Mendel examined many crosses involving traits found in pea plants. He identified being tall as dominant (T)
and short as recessive (t). What is the genotype of a heterozyous tall plant?
Answer:
Tt
Explanation:
Heterozygous means the organism has two different alleles, one for tall and one for short.
Gametes (SEX CELLS) have ... A. half the number of chromosomes found in the body cells B. twice the number of chromosomes found in body cells C. two sets of chromosomes
Answer:
A. Half the number of chromosomes found in the body body cells
Explanation:
Somatic (body cells) have 2 sets of chromosomes, while gametes have 1 set of chromosomes. Sperm has one set, and an egg has one set allowing both to fuse to create a new organism.
Answer:
[tex]\boxed {\boxed {\sf A. \ Half \ the \ number \ of \ chromosomes \ found \ in \ the \ body \ cells}}[/tex]
Explanation:
Gametes are sex cells, such as the egg and sperm. They are used in sexual reproduction to produce offspring.
The sex cells are produced during meiosis. The DNA or genetic material is replicated, then the cells divide twice. After this, four haploid cells are produced with half of the genetic material. For example, human body cells have 46 chromosomes but sex cells have 23 chromosomes.
They contain half the genetic material for an important reason. During fertilization, an egg and a sperm fuse. Each one contributes half of the genetic material from the mother or father to create one complete set for the offspring.
Gametes have half the number of chromosomes in body cells and choice A is correct.
Explique de qué manera la deriva continental ha influido en la distribución de especies vegetales y animales en el mundo.
Answer:
la deriva continental ha notablemente influido en la distribución actual de las especies. Este fenómeno se puede observar en grupos de organismos similares que se encuentran en diferentes continentes, lo cual concuerda con la idea de que la separación entre dichos continentes se produjo más tardíamente en el tiempo
Explanation:
La teoría de la deriva continental plantea que durante el final del Paleozoico y el principio del Mesozoico (hace aproximadamente hace 225 millones de años) las masas continentales actuales se encontraban unidas formando una gran masa de tierra o supercontinente conocido como 'Pangea'. Esta teoría se basa en evidencia de diversa fuentes incluyendo pruebas geográficas (coincidencias en las costas de algunos continentes), paleontológicas (mismos fósiles en diferentes continentes), geológicas y tectónicas (por ej., la presencia de cadenas montañosas que se separaron hace millones de años), y paleoclimáticas (evidencia de climas similares durante el pasado en continentes diferentes). La deriva contiental afectó la distribución actual de especies de plantas y animales. Por ejemplo, la fauna en Europa es semejante a la observada en Norteamérica porque estos continentes se separaron más tardíamente en el tiempo que otros contientes/masas de tierra del hemisferio sur, y dichas semejanzas se encuentran reflejadas en organismos evolutivamente más relacionados (menor tiempo de divergencia evolutiva).
How does waste removal in a fetus differ from waste removal after birth?
A) Fetal waste is removed through the chorion; infant waste is removed through the rectum.
B) Fetal waste is removed through the rectum; infant waste is removed through the chorion.
C) Fetal waste is removed through the ductus venosus; infant waste is removed through the rectum.
D) Fetal waste is removed through the large intestine; infant waste is removed through the ductus venosus.
Answer: A) Fetal waste is removed through the chorion; infant waste is removed through the rectum.
Explanation:
A developing fetus is surrounded by chorion which is an outer membrane. The role of the chorion is to protect the embryo and provide nutrition to it in the form of blood supply. It helps in getting rid of waste products from the developing fetus that goes into the mother blood to remove out of her body. In case of infants the rectum is the last part of the digestive tract and it receives the waste in the form of fecal matter from small intestine which is removed out through the rectum.

Given a parent genotype of Bb, what are the possible gametes that they can produce?
Assuming both parents have genotype Bb, this would lead to the Punnett square (in this case a monohybrid cross) as shown in the image below. We have four outcomes, three of which are unique. Those offspring genotypes are: BB, Bb, and bb.
An offspring with B or b on its own is not possible because both parents contribute genes.

Tourniquet ____ Using your gloved hand to apply pressure on the wound to control bleeding ____ Bleeding that can be seen coming from a wound ____ The escape of blood from an artery, vein or capillary inside the body ____ A tight band placed around an arm or leg to constrict blood vessels in order to stop blood flow to a wound ____ Blood vessels that carry blood from all parts of the body to the heart ____ Vessels that transport blood to the capillaries for distribution to the cells ____ A bandage applied snugly to maintain pressure on the wound to control bleeding
Answer:
Using your gloved hand to apply pressure on the wound to control bleeding. b. Direct pressureBleeding that can be seen coming from a wound. a. External bleeding The escape of blood from an artery, vein, or capillary inside the body. d. Internal bleeding A tight band placed around an arm or leg to constrict blood vessels in order to stop blood flow to a wound. g. TourniquetBlood vessels that carry blood from all parts of the body to the heart. f. Veins Vessels that transport blood to the capillaries for distribution to the cells. e. ArteriesA bandage applied snugly to maintain pressure on the wound to control bleeding. c. Pressure bandageExplanation:
Direct pressure is a technique used to stop the bleeding on the wound. The person should place both hands over the wound and press firmly till doctors arrive. With this first aid technique, we prevent excessive blood loss, which can cause worse problems in the future.
There are two types of bleeding, external and internal. In the first one, the skin opens, and blood comes out to the exterior. In the second one, the skin is not open, so the blood does not come out to the exterior, but blood goes to tissues around the broken vessel due to an internal injury.
A tourniquet is a first-aid technique use to stop blood flow and prevent that the injured person bleeds out till death. A band, a piece of shirt, or a belt should go around the limb and tie it hard to stop the blood flow and allow the patient to arrive at the hospital. It is a technique usually use when there is a wound that affects the main vessels.
There are different types of vessels. They change in size and structure. Veins are the vessels that carry blood back to the heart, where it will go to the pulmonary circuit to be oxygenated. Arteries will take the oxygenated blood from the heart to the rest of the body. The arteries branch into small vessels called arterioles, and the arteries branch into capillaries which will give oxygen to the cells.
A pressure bandage controls bleeding and prevents the injury from being contaminated. The pressure bandage does not restrict blood flow as a tourniquet.

What concept does Hubble's Law most concern?
A. energy lost over time across the universe
B. growing distance between galaxies
C. how stars recycle energy and matter
D. how the universe will eventually end
Hubble's Law most concern with growing distance between galaxies. Thus option B is correct.
What is Hubble's Law ?Hubble’s law refers to the observation in physical cosmology where the movement of galaxies from the Earth at a speed that are proportional to their distance.
The velocity of the galaxy which is called as the redshift.
This laws study physical cosmology and is also known as Hubble-Lemaitre law.
After measuring recession velocity one can determine the distance of the galaxy from us by using Hubble’s equation.
Some limitations are; due to intrinsic motion of galaxies, observed velocity gets influenced and Galaxy orbit due to gravitational movements.
Hubble constant is another unit of measurement, which is used for description of the expansion of the universe. It is 160 km/s per million-light-years.
Thus option B is correct.

Population Growth
Project: Analyzing Factors That Affect Carrying Capacity and Biodiversity
In this assignment, you will use simulations to analyze how climate, resources, and habitat size affect
carrying capacity. You will then look at another simulation to analyze the effects of certain factors that
affect biodiversity and populations. Finally, you will write and revise a conclusion on how human activity
affects biodiversity.
Background Information
Population growth is the change in size of a group of organisms of the same species over time. It is
affected by four factors: birth rate, death rate, immigration, and emigration.
Carrying capacity is the maximum total population that an area can support. Carrying capacity limits
population growth and is affected by competition for food, water, shelter, or mates, and threat of
predators, disease, and parasites. Carrying capacity may be affected by one or a combination of these
factors.
Biodiversity is the total variety of organisms that live in the biosphere. Biodiversity is affected by the loss
of habitat, introduction of invasive species, pollution, and/or human activities.
Answer:
Question 1: How does increasing the size of the habitat affect carrying capacity? Explain your answer. Recall the scenarios: 0–15 years, Little land; 15–30 years, Moderate land; 30–45 years, Ample land.
Population numbers self-regulate to some extent since mortality rise when a population exceeds its carrying capacity. Carrying capacity is affected by disease, competition, predator-prey interactions, resource usage, and the number of populations in an ecosystem.
Explanation:
Question 2: How and why did changes in the environmental conditions affect carrying capacity in this scenario? Recall the scenarios: 0–15 years, Harsh winter; 15–30 years, Harsh winter and Cold spring; 30–45 years, Harsh winter, Cold spring, and Hot summer.
The carrying capacity of an environment is also affected by conditions within or adjacent to it. If the environment is adjacent to a human population, for example, this may have an impact on its carrying capacity. Pollution can also have an impact on the carrying capacity of an environment.
Question 3: If there were no other changes in the habitat, would the value under “Larger Than Ample” be correct? Why or why not
Climate change isn't only about global warming. While it is true that temperatures would rise during the summer months, it is also feasible that the winter months would be even colder. As a result of this effect, the winters will be exceptionally cold from year 0 to 15.
Question 4: Suppose there were changes in the habitat that caused this actual value. What might a combination of those changes be
Assume that the climate in a habitat shifts. The amount of precipitation reduces by 20% over time. It will have an impact on the habitat because species that have adapted to drier climates will supplant those that are less suited to the new climate. This best circumstance explains the cause for adaptation, and those that adapted rapidly will replace those who found it difficult to adapt, resulting in the extinction of species as those who can thrive will be able to cope with the rapid shift in the environment. The most fittest survive in the new environment, according to Charle's Darwin thesis.
Question 5: How would you describe the effect of a 1°C increase of temperature on the biodiversity of the habitat in terms of number of populations and number of individuals in the populations? Use evidence from your graph and table to support your answer
The graph and table in the supplied question were not provided, nor could they be found anywhere, hence the question was answered based on prior knowledge. Earth's species can adapt to their surroundings, however adaptation in organisms can take thousands to tens of thousands of years. However, for the last 200 years, a consistent rise in temperature has been recorded.
The thermal limits of species residing in the tropics, equator, and poles have already been altered. If the global average temperature rises by one degree Celsius, the number of people on the globe will drop. The population of a species will decline as the number of individuals decreases.

Which part of the blood is responsible for transporting oxygen throughout the body?
Answer:
The main job of red blood cells, or erythrocytes, is to carry oxygen from the lungs to the body tissues and carbon dioxide as a waste product, away from the tissues and back to the lungs. Hemoglobin (Hgb) is an important protein in the red blood cells that carries oxygen from the lungs to all parts of our body.
