h. stimulated by baroreceptors in blood vessels: 2. Sympathetic Nervous System
i. stimulated by low blood pressure or volume: 3. Both
Explanation:
The antidiuretic hormone is one of the hormones released by the hypothalamus (regulator center in the brain) and collected by the posterior hypophysis from where they are then released again to the system. This hormone, also known as vasopressin hormone, is released by changes in serum osmolarity or blood pressure. The osmotic receptors are located in the hypothalamus, while the pressure receptors are located in the heart, the aorta, and carotids. The amount of hormone secreted depends on these two aspects. Its function is to keep homeostasis and make kidneys conserve or excrete water to regulate its volume. The antidiuretic hormone stimulates water reabsorption when factors such as dehydration or hemorrhages are causing an increase in blood solutes. It might also stimulate water excretion when solutes in the blood are very low or blood pressure is too high.
Aldosterone is another hormone that acts stimulating the sodium ions reabsorption. This hormone production is controlled by a circuit named the renin-angiotensin-aldosterone system. This system is activated by the decrease of blood supply to the kidney, and hence, the decrease in blood pressure and sodium concentration. These factors cause the release of the renin, a proteolytic enzyme that acts on angiotensinogen producing angiotensin I which is converted into angiotensin II. Angiotensin II is a peripheric vasoconstrictor peptide, that can increase the blood pressure when it is circulating in the plasma. It also stimulates the secretion of aldosterone.

The pygmy shrew is the smallest mammal in North America. However, when comparing the amount of
food eaten to its body weight, the pygmy shrew eats more food than any other mammal. It will
consume two to three times its own body weight in food daily. One explanation is that the pygmy
shrew uses energy at a high rate. In fact, its heart beats over one thousand times per minute.
What is the best explanation for what happens to the food's mass and energy when it is consumed by
the pygmy shrew?
A. The mass is mostly excreted as waste. The
energy is burned up and destroyed by the
pygmy shrew's high rate of cellular respiration.
B. The mass is all used for creating new mass in
growth. The energy is stored, used in cellular
respiration, or lost to the environment as heat.
C. The mass is used for growth, stored, or excreted
as waste. The energy is stored, used in cellular
respiration, and lost to the environment as heat.
D. The mass is used for growth, stored, or excreted
as waste. The energy is burned up and
destroyed by the shrew's high rate of cellular
respiration
Answer:
C. The mass is used for growth, stored, or excreted
as waste. The energy is stored, used in cellular
respiration, and lost to the environment as heat.
Explanation:
I got it right on the quiz.
Mass used for growth, stored or excreted as waste. Energy is stored that is used in cellular respiration which is lost to the environment in the form of heat. So, the correct option is (C).
How Pygmy shrew uses its food for energy?The pygmy shrew has a large appetite which is a result of small body mass, rapid heat loss and high metabolic rate. It is kept in captivity which provides some idea of the energy requirements of the species.
The pygmy shrew has such a high metabolism that it must eat at least every 30 minutes otherwise it will die. This can be explained by food mass and energy is that due to very high metabolism most of the food mass which is rapidly used up to form shrew, and a large proportion of the food is lost from the body surface because of its very small size.
The combination of these two factors are
1. A very high metabolism which is rapidly utilizes food material, and generates large amounts of heat in a very short period of time.
2. Very small size due to which high surface area to volume ratio leading to heat loss.
Thus, Mass used for growth, stored or excreted as waste. Energy is stored that is used in cellular respiration which is lost to the environment in the form of heat. So, the correct option is (C).

Intrinsic factor A. increases gastric motility. B. causes the release of stomach acid. C. facilitates the absorption of vitamin B12. D. protects the stomach lining from the effects of stomach acid. E. stimulates the synthesis of DNA.
Answer:
C. facilitates the absorption of vitamin B12.
Explanation:
The Intrinsic factor is a substance that is produced by the stomach and it has the important function of producing vitamin B12 which is necessary for life. Vitamin B12 is used in the production of mature red blood cells. It also improves the function of the nervous system. The production of this intrinsic factor is a very vital role of the stomach because, in the absence of a stomach, for example, in the case of a gastrectomy, a person can only survive if he is given injections of Vitamin B12.
The stomach also serves as a holding center for food and eventually delivers the food to the small intestine and the duodenum.
A couple has just learned their neonate is diagnosed with osteogenesis imperfecta, and they
ask, "What caused our child to get this disease?" What should the health care provider teach
the couple about their neonate's condition?
Answer:
osteogenesis imperfecta is an inherited genetic disease that mainly affects the bones.
Explanation:
Osteogenesis imperfecta is an inherited genetic disease associated with alterations in collagen synthesis, which have been shown to increase the risk to suffer bone fractures. This genetic disorder is characterized by different health problems including, among others, fragile bones, reduced skeletal mass, skin hyperlaxity, malformations in the central nervous system, etc. Clinically, osteogenesis imperfecta must be managed by an interdisciplinary medical team, since patients may present a clinical picture ranging from mild to lethal. In the first place, it is imperative to provide health care to avoid fractures, exercises to maintain muscle mass, exercise to improve motor skills, skincare by specialized dermatologists, etc.
The disease 'osteogenesis imperfecta' is caused by the neonate inheriting it
from either of the parent because it's a genetic disorder. The health care
provider should teach the parent about how to prevent the effect of having
such disease such as bone fractures.
Osteogenesis imperfecta is a genetic disorder inherited by offspring from
their parent. The disease involves individuals having very brittle bones which are easily broken. The nurse should teach the parent to adopt bone strengthening steps such as adequate calcium intake and physiotherapy.

Biologists designed an experiment to test the effects of compost on the development of root crops
Answer:
The crop has good yield because Compost has a good effect on root crops.
Explanation:
Compost has a great effect on the development of root crops such as onion, potato, garlic and ginger etc. Compost provide nutrients to these crops as well as soften the soil due to which they grow rapidly. It also improved ventilation, soil structure and soil texture which is very necessary for the crop. Due to ventilation, oxygen gas is available to the roots which increases growth and yield of these crops. Compost also retain water and nutrients so they are available to the roots. So those plots where compost is applied observed increase in yield as compared to other plots.

During the Paleocene-Eocene Thermal Maximum, when global surface temperatures spiked, we observe temperate forests ____________________, insect herbivory of temperature.
Answer:
The overview of the problem concerned is listed below.
Explanation:
Mostly during Paleocene Eocene Temperature Optimum, we consider temperate vegetation momentarily relocated towards the poles whenever global average surface temperature jumped, bug harvesting temporarily escalated, as well as coral reef crashed.The level of variations in climate or temperature was as sluggish as it is today, which suggests that such past occurrences are likely to overestimate the effects of rising temperatures nowadays.Increase occur in the insect's population due to increase occur in global surface temperature.
During the Paleocene-Eocene Thermal Maximum, when global surface temperatures increase, we observe temperate forests having more population of insects due to favourable temperature for the growth of insects.
The productivity and distribution of forests could be affected due to change occur in the temperature, precipitation and the amount of carbon dioxide in the air. As the temperature increases the population of insects also increases which leads to increase in biodiversity of forest so we can conclude that increase occur in the insect's population due to increase occur in global surface temperature.

Draw a cross section of a peach, and label the structures. What parts of the flower give rise to these structures
Answer:
exocarpo is synonymous with exocarp
endocarpo is synonymous with endocarp
mesocarpo is synonymous with mesocarp
semilla is synonymous with seed
Explanation:
In phase one, the plant's ovary begins to grow abruptly, this is where the embryo and endosperm affect their size, but if this ovarian growth is interrupted by an external factor, it determines the size of the future.
Then, the embryo and the endosperm could grow and undergo a process called sclerification, which is the hardening of the interior of the fruit, that is to say, the future formation of the seed or vulgarly called "pit". .
After this, the mesocarp, which is what is called the fleshy body or subglobose edible drupe, begins to grow.
The growth of the mesocarp is what gives the volume, weight and body to the fruit, so that after maturation it exceeds the strength of the branch and it falls from the tree.
After entering a dark room, you turn on a light switch, but the light does not come on. Please suggest three different hypothesis that might explain your observation. Please also note how you might test these hypotheses and describe what observation(s) may lead you to conclude that one of the hypothesis is correct.
Answer:
First hypothesis; may be the power is cut. ( no power supply) Second hypothesis; may be the light switch is defective ( wall switch not working )Third hypothesis; maybe the bulb is burnout ( light bulb may not be working )Explanation:
The three possible hypothesis for light not to turn on immediately after one on the switch are;
First hypothesis; may be the power is cut. ( no power supply) Second hypothesis; may be the light switch is defective ( wall switch not working )Third hypothesis; maybe the bulb is burnout ( light bulb may not be working )We test the first hypothesis, how?
We check if other electronics connected to the same sources of power supply as the bulb is working. If the electronics are not working, then the first hypothesis is correct but if they are working then the hypothesis fails and we move on to test the next hypothesis.
To test for the second hypothesis as the first hypothesis fails, we remove the bulb and fix it into another socket which has a working switch. If the bulb comes on then the second hypothesis is correct but if the bulb does not turn on then the hypothesis fails so we move on to test the third hypothesis.
As the bulb fails to turn on in our initial socket and a second bulb is fixed in that same socket and it came on, then the third hypothesis is correct.
The three hypotheses we can derive from entering a dark room, turning on a
light switch,and the light not coming on include
There may be no power source at that momentThe bulb may be faultyThe switch may be faultyA power source helps to provide energy to power up an appliance and where it is absent, the bulb won't light up.
A defect in the switch and bulb may also hinder the light from coming on as
the switch controls electric current flow while the bulb produces the light.

Without this, many cycles such as the water cycle and photosynthesis would not exist. What could all these cycles not exist without?
Answer:
This question appears incomplete
Explanation:
This question appears incomplete. However, one similar substance that, if missing, many cycles (particularly the two cycles/processes provided in the question) will not exist/proceed is the sun/sunlight.
In the water cycle for instance, if there is no sun/sunlight, there will be no heat to allow for evaporation of water from the water-body (ocean, sea, stream or lake) hence there will be no cloud of water droplets in the atmosphere. The implication of this is that, the first process of the water cycle will not proceed, hence the cycle will not exist.
During photosynthesis, carbondioxide reacts with water in the presence of sun/sunlight to produce glucose and oxygen. The absence of sun in this reaction will not lead to the production of glucose which is the useful product of photosynthesis for plant.
From the explanation above, it can be deduced that the absence of the sun/sunlight will prevent the two cycles from existing.

Answer:
genetic variation
Explanation:
Genetic variation refers to the difference in genetic content of organisms within a population. The genetic makeup of living organisms are made up of GENES, which exists in contrasting pairs called ALLELES. Each allele is responsible for variation in traits exhibited by the organisms. Differences in the allelic content of organisms of the same species leading to the display of varying phenotypic characteristics is referred to as GENETIC VARIATION.
This is the case in the example given in which four birds in a population possess a range of wing and feather colors i.e light brown feathers with darker wings, dark feathers with lighter wings, medium brown feathers with light wings, and medium brown feathers with very dark wings, all resulting from a variation in their genetic content. Hence, this is an example of GENETIC VARIATION.

a. They produce β-lactamase that provides resistance to ampicillin.
b. They carry a vector that contains a DNA fragment inserted into the multiple cloning site.
c. They produce functional β-galactosidase that cleaves X-gal.
d. They carry a vector with a lacZ gene that has been disrupted and rendered nonfunctional.
e. They carry a vector with the bla gene used as the selectable marker.
Answer:
c. They produce functional β-galactosidase that cleaves X-gal.
Explanation:
β-galactosidase is an enzyme capable of catalyzing the enzymatic hydrolysis of β-galactosides into monosaccharides by hydrolyzing the β-glycosidic bond. On the other hand, X-gal is an analog of lactose composed of galactose, which is widely used in laboratories for the detection of β-galactosidase. In the presence of β-galactosidase, X-gal is hydrolyzed by cleaving its β-glycosidic bond, thereby confirming the presence of β-galactosidase.

Food microbiologists are scientists who have a background in both microbiology and food science. They focus on how microbes grow, cause disease, and how they can be identified from food. Their work is of importance to the food industry as it relates to the production, preservation, and spoilage of food; and it is of importance to public health and regulatory agencies due to the many diseases that are related to food intake and consumption. Food microbiologists can have varying backgrounds, including training in veterinary medicine. This scenario is about a food microbiologist who works as a food safety inspector who pays a visit to a cheese manufacturing plant and makes some interesting discoveries!
Part A-Understanding the Role of Microbes in Fermentation The Midwest is known for its contribution to the dairy industry Fermented dairy products include milk, yogurt, and cheese. The fermentation process relies on lactic acid bacteria and pasteurization. Fermentation can vary based on what food is being produced, the type of bacteria used to produce lactic acid, and the time and temperature of pasteurization. It is important to the manufacturer to produce a product that won't spoil before it is packaged and sold and that won't result in disease for those who ingest and enjoy it. Julie, a food inspector for a local Michigan health department is going to a nearby cheese plant for a biannual inspection. When she gets there, she will take a tour of the plant and allow the operators to describe what makes their cheese so special. She will use what she understands about fermentation to inquire about their production practices Please sort the following statements as being true or false regarding fermentation and its role in food production. Please recall the role that microorganisms can play in the production of foods.
