Answer:
The human pelvis Is use for determining sex of skeletal remains. The woman pelvis provide optimal space for birth canal which is shown in the morphology and relationship of it's different part. Skull is also use.
The fourth ribs is use for determining the age of skeletal remains.
Explanation:
The human pelvis is use to determine the biological sex of skeletal remains. The woman pelvis is wider than man's and it provide space for birth canal.
The fourth ribs is use to estimate the age of skeletal remains as the cartilage between the ribs and sternum gradually turn as time goes on. The features of the head can also be use to estimate the age of skeletal remains.
Blood plays an important role in thermoregulation. Which of the following statements
about thermoregulation is NOT correct
A. Thermoregulation involves a balance between the production of heat and
the loss of heat.
B. The rate of heat loss is affected by the difference between temperature
of skin and external environment.
C. Internal conditions remain the same regardless of the external
conditions.
D. Heat loss from surface of the body is slower when the temperature
difference is higher.
E. Heat loss from the body deceases as more blood passes through the
skin.
Answer: C and E options not correct.
Explanation:
Thermoregulation itself is actually a branch of homeostasis. Homeostasis is defined as the internal regulation of body environment which includes the vital organs of the body such as the heart, liver, brain and contraction of skeletal muscles.
However, there are four routes of heat lost in the body. They are through convection, conduction, radiation, and evaporation. If skin temperature is greater than that of the surroundings, the body can lose heat by radiation and conduction. But, if the temperature of the surroundings is greater than that of the skin, the body actually gains heat by radiation and conduction. In such conditions, the only means by which the body can rid itself of heat is by evaporation. So, when the surrounding temperature is higher than the skin temperature, anything that prevents adequate evaporation will cause the internal body temperature to rise. Even during sports activities, evaporation becomes the main avenue of heat loss. Humidity itself, affects thermoregulation by limiting sweat evaporation and thus heat loss.

The pyruvate dehydrogenase complex is subject to allosteric control, especially inhibition by reaction products. The main regulatory process controlling pyruvate dehydrogenase's activity in eukaryotes is:
a. Exchange of ADP and ATP on the pyruvate dehydrogenase complex.
b. AMP binding to and activating the enzyme.
c. Phosphorylation by ATP, which turns the complex on, and dephosphorylation, which turns the complex off.
d. Phosphorylation by ATP, which turns the complex off, and dephosphorylation, which turns the complex on.
Answer:
d. Phosphorylation by ATP, which turns the complex off, and dephosphorylation, which turns the complex on
Explanation:
Pyruvate dehydrogenase complex (PDC) is a complex enzymes which is responsible for the conversion of pyruvate into acetyl-CoA, NADH and CO2 through oxidative decarboxylation.
Pyruvate dehydrogenase is one of the main component of PDC that catalyze conversion of pyruvate to acetyl-CoA. Pyruvate dehydrogenase (PDH) enzymes is first modified by covalent modification in the pyruvate dehydrogenase complex. Pyruvate dehydrogenase kinase undergo phosphorylation with ATP and inactivates PDH which turns the complex off. then the pyruvate dehydrogenase phosphatase support dephophorylation which turns the complex ON.
Hence, the correct option is d.

Which best describes an organism’s niche? A. life span B. habitat C. environment D. role
Answer:
role
Explanation:
An ecological niche is the role and position a species has in its environment; how it meets its needs for food and shelter, how it survives, and how it reproduces. A species' niche includes all of its interactions with the biotic and abiotic factors of its environment.
An ecological niche is the role and position a species has in its environment; how it meets its needs for food and shelter, how it survives, and how it reproduces.
What is Niche?A species' niche includes all of its interactions with the biotic and abiotic factors of its environment.
The term "niche" in ecology refers to the function an organism performs within a community. The physical and environmental requirements (such as temperature or topography) and interactions with other species that a species must tolerate make up its niche (like predation or competition).
For instance, the tiny songbird from North America known as the Kirtland's warbler (Setophaga kirtlandii), which is scarce, has an extremely constrained niche.
Therefore, An ecological niche is the role and position a species has in its environment; how it meets its needs for food and shelter, how it survives, and how it reproduces.

What releases glucose into the blood stream?
Answer:
Insulin helps your body turn blood sugar (glucose) into energy. It also helps your body store it in your muscles, fat cells, and liver to use later, when your body needs it. After you eat, your blood sugar (glucose) rises. This rise in glucose triggers your pancreas to release insulin into the bloodstream.

Use the word bank below to complete the passage below describing mitosis and meiosis. All words will be used at least once and most words will be used more than once.A) diploidB) mitosisC) meiosisD) sister chromatidsE) haploidF) homologous chromosomes1) A male giant panda has 42 chromosomes in its skin cells. This represents the _________ chromosome number. As the animal's old skin cells die and slough off, cells nearby divide through _________ to produce more skin cells. 2) Germ cells within the animal's testicles undergo _________ to replicate themselves and _________ to produce sperm. 3) The cells produced by mitosis in this panda have a _________ chromosome number and are produced after _________ are pulled apart into separate daughter cells.4) The cells produced by meiosis I in this panda have a _________ chromosome number and are produced after _________ have been pulled apart into separate daughter cells. 5) The cells produced by meiosis II in this animal have a _________ chromosome number and are produced after _________ have been pulled apart into separate daughter cells.
Answer:
1. diploid ,Mitosis
2. mitosis, meiosis
3. diploid, sister chromatids
4. haploid, homologous chromosome
5. haploid, sister chromatids
Explanation:
1. The Giant Panda has 42 chromosomes but these chromosomes exist in the form of homologous pairs therefore the Panda are diploid organisms. The somatic cells of the Panda undergo mitosis like skin cells.
2. The Germ cells are present in the testicles of the Panda which makes an exact copy of themselves by mitosis but these germ cells undergo meiosis to produce sperms.
3. The Mitotic division forms two daughter cells with the same genetic material because the sister chromatids of homologous chromosomes move to the opposite pole.
4. The meiosis I am also known as reductional division as the homologous chromosome separate and move to opposite poles during meiosis I and the ploidy changes from diploid to haploid.
5. During meiosis II, the sister chromatids of a chromosome separate and move to the opposite poles as a result of this the haploid cells are formed.

Which type of reproduction involves the passing of characteristics to offspring? A. only sexual
B. only asexual
C. both sexual and asexual
D. neither sexual or asexual
Answer:
C. both sexual and asexual
Explanation:
In both cases, the parent(s) of the offspring pass down characteristics. Asexual reproduction makes a carbon copy of the parent so they would obviously have the parent's characteristics. Sexual reproduction passes down characteristics of both parents to the offspring.

When fewer visual pigment molecules are available to absorb light (for example, when a person has a color weakness), which of the following nervous system responses occurs? A.Fewer signals of the weakly perceived color are sent to the brain. B.A normal number of signals of the weakly perceived color is sent to the brain, but each signal is less intense. C.The signals for the weakly perceived color are sent to the brain via other, more plentiful, pigments. D.Light molecules stimulate the cells to make additional pigment.
Answer:
A.Fewer signals of the weakly perceived color are sent to the brain.
Explanation: the brain is the seat of nervous coordination where nerve cells sends signals for processing. An individual with a weak color means a fewer signal for color production is sent to the brain this is due to low pigment it had hence fewer pigment molecule are available to absorb light. If the pigment is high the signal sent will also be high.
