Answer:
CRISPR can also be used to make precise changes such as replacing faulty genes – true genome editing – but this is far more difficult. Customised Cas proteins have been created that do not cut DNA or alter it in any way, but merely turn genes on or off: CRISPRa and CRISPRi respectively.

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).

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.
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.

Explain why reintroducing wolves changed the ecosystem of the park?
WILL GIVE BRAINLIEST
Answers
Answer:
After 70 years without wolves, the reintroduction caused unanticipated change in Yellowstone's ecosystem and even its physical geography. ... The healthier bear population then killed more elk, contributing to the cycle the wolves started.
Explanation:
The reintroduction of wolves had several positive effects on the ecosystem.
What are the effects of reintroduction of wolves?The reintroduction of wolves caused a trophic cascade of events in the Yellowstone national park. This resulted in an increase in the population of beavers and also brought back several forms of vegetation.
The killing of wolves in the 1930s resulted in the shifting of predatory pressure on the elk population. But, they were much less active in winter. They browsed on cottonwood plants and aspen.
But now, the predatory pressure came back on wolves. This keeps the elks more active. This also resulted in an increase in vegetation.
The reintroduction of wolves also resulted in the increase in the population of beavers because of the recovery of willow strands reflourished due to the activeness of the elk.
Therefore, the reintroduction of the wolf population greatly impacted the ecosystem of the Yellowstone national park causing a ripple of positive effects.

How can fracking impact water quality? (1 point)
A.Methane leaks make the water supply flammable.
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.

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.
Answers
Answer:
2. Sarah
Explanation:
because she is stronger, she is able to pull faster and easier because of the amount of weight she can carry vs the amount of weight you can carry. Although you are the same height, she has more muscle.

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.
