Answers

Answer:c

Explanation:

Bc

A biome is a major community of plants and animals living in a specific geographic area and adapted to specific climate conditions. There are five major types of biomes: grassland, forest, desert, aquatic and tundra.

These major biomes can be divided into different categories (e.g., temperate grasslands).

The grassland is a biome that has grasses as the dominant vegetation.

The temperate grasslands have in common the same seasonal patterns of temperature and precipitation (Option C).

In these regions (temperate grasslands) rainfall is insufficient to support trees.

The temperate grasslands have four well-defined seasons. i.e., spring, summer, fall (autumn), and winter.

Some examples of temperate grasslands include Argentine pampas, Euro Asian steppes and North American prairies.

In conclusion, the temperate grasslands have in common the same seasonal patterns of temperature and precipitation (Option C).

The Arizona poppy has adapted to living in areas that receive less rain, but there are still periods of time that a drought occurs. What part(s) of photosynthesis would the plant not be able to perform if there is no rain? What would be the long-term effects on the plant if the drought were to continue? Explain your answer.

Answers

Answer:

I guess it would not grow??

Explanation:

Answer:

When plants lose more water than they can take up from the soil, they become water stressed. ... Such drought conditions certainly inhibit the growth of plants. If it goes long enough without water it will die because the plant uses water for a lot of different jobs needed to keep the plant alive, so the long-term effect is that the plant will die if the drought continues.

1. You and Tim, who is larger than you are outside with a wagon. Tim (the bigger person) gets in the wagon and you (the smaller one) pull it. As you pull
it, you accelerate until you reach a comfortable velocity. Then you stop and switch places with Tim. Tim now pulls you in the wagon, accelerating
from a stop to a comfortable velocity. Now, Tim may be bigger than you, but you have been working out and are just as strong as Tim, so the force
that Tim uses to pull the wagon is the same force that you used. You both pull with the exact same amount of force. Who was riding in the wagon
when it had the greatest acceleration during start up? Why? Use Newton's second law to explain.
2. Now Sara comes along, and she is the exact same size as you. However, she is even stronger than you! When she pulls you in the wagon, she pulls
with a greater force than when you pull her. Now who is in the wagon when it has the greatest acceleration? Explain, using Newton's second law.

Explain why meiosis is such a critical process in the inheritance traits. Be as specific as you can.

Answers

Answer:

It ensures that sexually reproduced offspring have the correct amount of chromosomes when born, this ensures that disorders such as down syndrome don't occur. It also makes genetic variation possible, by way of genetic recombination, this is so that siblings don't look exactly the same, disregarding twins.

Explanation:

Meiosis is such a critical process in the inheritance of traits, and meiosis is important because it ensures that each daughter cell receives the correct number of chromosomes from the parent cells.

What is the significance of the inheritance of traits?

Inheritance of traits allows for the transfer of beneficial traits from one generation to the next, allowing populations to adapt to changing environmental conditions, and the study of inheritance of traits can provide insight into the underlying genetic causes of diseases. The understanding of the traits helps in the improvement of agriculture and in other fields of biology.

Hence, meiosis is such a critical process in the inheritance of traits, and meiosis is important because it ensures that each daughter cell receives the correct number of chromosomes from the parent cells.

Which best compares self-renewal and differentiation?
O Both are processes that are the result of stem cell division.
O Both create more of the same types of cells.
O Both form specialized cells.
O Both depend on gene expression.

Answers

Answer:

Both are processes that are the result of stem cell division

Explanation:

Self-renewal and differentiation are the property of the stem cells. Both the processes result from stem cell division. Thus, option A is correct.

What are stem cells?

Stem cells are the special cells that can produce other types of cells from differentiation. For example, the Hematopoietic Stem Cells give rise to the blood cells that can be RBC, WBC, etc.

Differentiation is the process where the less specialized cells give rise to a more specific cell type. The stem cells also undergo self-renewal where the same cell type is also produced.

Therefore, both process results from stem cell division.

Compare the thickness of the right and left ventricles. Which ventricle is thicker the right or left. Explain the difference.

Answers

Answer:

When comparing the thickness of the heart's ventricles, the left one is thicker than the right one, because it must generate more pressure to pump blood throughout the body.

Explanation:

In the human heart, the right ventricle is in charge of pumping the blood to the lungs —initiating the minor circuit of the circulation— while the left ventricle is in charge of pumping the blood to the whole body.

To fulfill its function, each ventricle has a specific thickness in its walls, the left one being thicker than the right one.

The right ventricle is a chamber that handles more volume than pressure, and its walls are thinner because it does not require much pressure to pump the blood to the lungs. The left ventricle has a thicker muscular wall because it is a chamber that must generate a high pumping pressure, so its contraction force must be greater.

The structure of the myocardium in the heart is what allows each chamber to fulfill its function adequately.

B.Power pumps drain water from rivers and reservoirs.
C.The heated water becomes unfit for consumption.
D.Smelting releases toxic metals into the water supply.​

Answers

Answer:

a

Explanation:

Due to the current relationship with groundwater and surface water, fracturing fluids like return fluids might pose a risk to both, hence option a is correct.

What is fracking?

It's possible for water to get contaminated during fracking owing to chemicals that are accidentally spilled,in the water during the migration of thermogenic methane gas.

Since a hydraulic fracture might intercept a natural fracture, such as a geological fault, and be connected to the surface, this presents another potential source of pollution.

Therefore, presence in the subsoil may be encouraged during the fracturing process, which may enhance the incidence of chemical reactions and the production of new contaminating substances, hence option a is correct.
