To discover the location of a genetic mutation that causes disease in humans, scientists use genetic mapping. Specifically, they

look for genetic markers, or previously discovered DNA polymorphisms, that show statistical association with the disease gene. The statistical association means that the:
a. DNA polymorphism causes the disease.
b. disease causes the DNA polymorphism.
c. DNA polymorphism and the disease gene are unlinked.
d. DNA polymorphism and the disease gene are linked.

Answer:

The correct answer is d. DNA polymorphism and disease gene are linked.

Explanation:

DNA polymorphism helps to study the difference in nucleotide sequence of one DNA in comparison to the standard one.

      DNA polymorphism is an important tool to analyze the disease that is caused due an alteration of gene sequence leading to genetic mutation.

Now the altered gene sequence is compared with the normally functioning gene to draw a statistical relationship between altered gene sequence that causes disease with  peviously discovered DNA polymorphism.

What is not a unique property of water
timofeeve [1]

Answer:

Water molecules stick together by cohesion

Explanation:

This sticking together of like substances is called cohesion. Depending on how attracted molecules of the same substance are to one another, the substance will be more or less cohesive. Hydrogen bonds cause water to be exceptionally attracted to each other. Therefore, water is very cohesive.

Why do plant cells have a cell wall and plant cells don’t?
Minchanka [31]
So animal cells can have various shapes, but plant cells only havethe shapes of their cell walls. That's nice for plants, because it gives them the ability to grow up and out, where they can get lots of sunlight for making their food.

In particular, organelles called chloroplasts allow plants to capture the energy of the Sun in energy-rich molecules; cell walls allow plants tohave rigid structures as varied as wood trunks and supple leaves; and vacuoles allow plant cells to change siz
Exactly why plant cell have wall and animal cell don't :-Cell walls are supporting structures that help the plant to have a fixed shape and protect it from injury. Other than that, it helps to keep the plant turgid so that it can stay firm and upright. Because when it enters a high water potential solution, as water moves in, the water exerts turgor pressure on the cell wall and the cell wall thus exerts an opposing pressure to keep water out. Hence cell wall is needed for the plant.

On the other hand, animal cells do not need to keep the structures, as they have the skeletal system to protect the organs and cushion them against any external Injuries.


This was the all information I had thank you.

2.tidally

3.spin

4.Kuiper

5.A solar nebula forms when the gas and dust are pulled together in a spinning disk. Particles began to clump together due to gravity, and larger chunks of material exert more gravity on nearby dust and gas. These chunks of material grew faster and formed planets or moons. Denser elements such as iron settled closer to the center of the solar nebula.
