Answer:
DNA evidence can show the evolution patterns of organisms, the relationships among species, and how evolution occurs. Because of this, DNA evidence can show how closely related organisms are by comparing DNA and genetic codes to show their shared ancestry and how they evolved.
Hope this helps! :)
Summarize the functions of blood below by providing a description:
Protection
Transportation
And temperature regulation
If anyone could help me with this I say thank you!
Explanation:
Blood has various functions that are central to survival. They include:
supplying oxygen to cells and tissuesproviding essential nutrients to cells, such as amino acids, fatty acids, and glucoseremoving waste materials, such as carbon dioxide, urea, and lactic acidprotecting the body from diseases, infections, and foreign bodies through the action of white blood cellsregulating body temperatureRift valleys can form when fractures in Earth’s crust widen. The valley walls slowly move at a rate of only a few millimeters a year. Which of these best describes the type of tectonic activity that forms rift valleys?
Answer: When fractures in the earths crust widen

3. How do gases from the air help break down rocks?
4. How does erosion make more soil? *
5. Explain how erosion can be helpful to the environment. *
6. Explain how erosion can be harmful to the environment. *
Answer:
3) Chemical weathering changes the molecular structure of rocks and soil. For instance, carbon dioxide from the air or soil sometimes combines with water in a process called carbonation. This produces a weak acid, called carbonic acid, that can dissolve rock.
4) Soil erosion is a gradual process that occurs when the impact of water or wind detaches and removes soil particles, causing the soil to deteriorate. The impact of soil erosion on water quality becomes significant, particularly as soil surface runoff. Sediment production and soil erosion are closely related.
5) Natural soil erosion can play a beneficial role in the environment too. ... The erosion also helped cleanse the soil of any useless materials, such as rotting tree matter or nutrient-less dirt from the area. The replaced soil can often become nutrient-rich and help plant life thrive.
6) The effects of soil erosion go beyond the loss of fertile land. It has led to increased pollution and sedimentation in streams and rivers, clogging these waterways and causing declines in fish and other species. And degraded lands are also often less able to hold onto water, which can worsen flooding.

Explanation:
In humans, a widow’s peak hairline is determined by the dominant allele (W), and a straight hairline is determined by the recessive allele (w). If a male is heterozygous for a widow's peak and a female has a straight hairline, what is the probability they will have a child with a straight hairline?

The folded mountains is an example of which type of plate boundary?
Answer: Contential Crust
Explanation:
what comes from centrioles and are used to move chromosomes in animal cells
-cell plates or C. Spindle Fibers
Answer:
I think Spindle Fibers
Answer:
Spindle Fibers
Explanation:
Spindle fibers emerge from the centrioles of the cell and pull the chromosomes to both sides of the cell during prophase. By anaphase, the chromosomes have divided and reach either pole of the cell.
So, the answer is C) Spindle Fibers

A patient who was in a car accident has lost their sense of smell. Which part of the brain is likely injured?
medulla
brain stem
cerebrum
cerebellum
Explain if you want brainliest
Answer:
There are three primary areas of the brain that control your sense of smell: The orbitofrontal cortex, located above and behind the eyes. The insula, which lies beneath the ears. The piriform cortex, located between the other two. Besides these three areas, there are smaller brain regions that also play a part in smell.
