Which of the following is not a line of evolutionary evidence supported by empirical evidence?
a. How similar DNA is between organisms
b. The length of the organism’s life
c. Where fossils are found
d. How similar the organisms were as embryos
Answer:c where fossils are found
Explanation:
Where fossils are found is not a line of evolutionary evidence supported by empirical evidence. Therefore, option C is correct.
What are fossils ?Any surviving remains, impression, or evidence of a once-living thing from a previous geological epoch is referred to as a fossil. Examples include exoskeletons, bones, shells, animal or microbe imprints in stone, items preserved in amber, hair, petrified wood, and DNA traces. The fossil record is the collection of all fossils.
Shells, bones, animal or microbe imprints in stone, exoskeletons, items preserved in amber, petrified wood, coal, hair, oil, and DNA traces are a few examples of fossils.
The majority of fossils are created when a living thing (such as an animal or plant) dies and is swiftly buried by sediment (such as mud, sand or volcanic ash).
Thus, option C is correct.

C. Extinction helps keep air and water clean.
D. Extinction makes the environment more pleasant.
Answer:
B. Extinction upsets the natural cycling of nutrients
The extinction of species affect humans as extinction upsets the natural cycling of nutrients. Therefore, option (B) is correct.
What do you mean by extinction of species?Extinction is the end of a sort of life form or of a gathering of sorts, normally an animal categories. The snapshot of annihilation is for the most part viewed as the passing of the last person of the species, albeit the ability to raise and recuperate.
As species go terminated, they are removed from the established pecking order. The animals that ate the species that has gone extinct must find new food or die. Other animal or plant populations could suffer as a result.
Habitat loss and degradation (primarily deforestation), overexploitation (hunting and overfishing), invasive species, climate change, and nitrogen pollution are the main modern causes of extinction.

QUESTION:
Tell me more about the parts of the water cycle and how they work.
ANSWER:
The water cycle consists of three major processes: evaporation, condensation, and precipitation. ... In the water cycle, liquid water (in the ocean, lakes, or rivers) evaporates and becomes water vapor. Water vapor surrounds us, as an important part of the air we breathe. Water vapor is also an important greenhouse gas.

The diagram shows the same type of molecules in area A and area B.
With the passage of time, some molecules move from area A to area B. This movement is the result ot the process of
1. phagocytosis
2. pinocytosis
3. diffusion
4. cyclosis
Answer:
3. diffusion, because molecules are moving from a high concentration(A) to a low concentration(B)
Diffusion is the net flow of matter from a location of high concentration to a region of low concentration as a result of the random mobility of molecules. Both stopping and reversing this process are not possible. Thus, option C is correct.
What are the main mechanism in diffusion process?The molecules' kinetic energy causes random motion, which causes diffusion. This mechanism happens in simple diffusion without the help of a carrier protein.
The molecules travel from an area of high concentration to an area of low concentration due to their random mobility.
Chemicals flow across the plasma membrane from areas of high concentration to areas of low concentration in cells to maintain an equilibrium (balance) of internal substances.
This implies that if there are more items inside the cell than outside, they will go outside and vice versa. It happens when the medium around the cell contains more water than the cell itself.
Therefore, This movement is the result of the process of diffusion.

Please help...Will mark brainiest....It is due and I need help
Answer:
Explanation:
For the 1st one with the Cheetah: It would be a long tail because it helps them balance when they turn. Sinch Cheetahs move extremely quickly they need a balance to ensure they don't topple over when they turn, this tail provides this balance.
For the 2nd one with the bear: Thick coats on a bare will help provide warmth whenever they go to hybernate. Thin fur would leave room for freezing and wouldn't be able to help them maintain the proper body temperature.
The 3rd one with the clownfish: A round tail provides a bigger boost when swimming since it is able to push more water. A forked tail would create a gap when they swim so they would have to expend more energy than with a round tail.
The 4th one with the Finch: Since grubs live underground a thinner beak would be able to dig them out and stab them faster. This allows them to reach farther and get more food.

During one year, seven coyotes in a population die. Eight immigrate into the population, but none emigrate. If the overall population growth is 13 coyotes, what was the birth rate of coyotes during the year? Use this formula: population growth = (birth rate + immigration) – (death rate + emigration) 7 11 12 15
Answer:
Death rate= 7 coyotes
Immigration= 8
Emigration= 0
Population growth= 13
Let’s suppose that the birth rate for the given population is x.
Population growth = (birth rate+immigration) - (death rate+emigration)
13=(x+8)-(7+0)
13=x+1
Move the variable to the left side and change its sign.
-x+13=1
Move the constant to the right side and change its sign

The statement which best describes trait distribution is: B. Distribution describes the different traits that are found in a population.
What is a trait?
A trait can be defined as a distinguishing quality, feature or characteristic that is possessed by a living organism and it differentiates from other species of organisms.
Generally, a trait is commonly transferred from the parent of a living organism to her offspring, so as to distinguish him or her from others.
