plsssss help me with this .Evidence for evolution from living organisms comes from comparisons of their DNA, similar bone structures, and embryo similarities. Pick one piece of evidence and describe how supports the theory of evolution. piece of evidence and describe how supports the theory of evolution are comparisons of their DNA, similar bone structures, and embryo similarities.
Answer:
I pick embryo similarities.
Explanation:
Vertebrates have a resemblance of their embryos. Such as birds, amphibians, fish, reptiles and mammals. Though there's resemblance but it doesn't form the same organism since there's evolution which might be due to geographic and ecological isolations.
Example, Amphibian embryo resemble with fish embryo.

what property of greenhouse gas make them important Earth's temperature?
Answer:
The greenhouse effect is a process that occurs when gases in Earth's atmosphere trap the Sun's heat. This process makes Earth much warmer than it would be without an atmosphere.
Explanation:
The greenhouse effect occurs as the gases reach Earth’s surface. As the short wave energy heats the surface, some of the longer wave energy radiates back into the atmosphere and back into space. Greenhouse gases absorb some of the energy and trap it in the lower atmosphere. Less heat radiates into space, and Earth is warmer.
what is the greatest degree of genetic diversity
Answer:
The greatest degree of genetic variation would be found in an offspring resulting from sexual reproduction.
Explanation:
Explanation: Asexual reproduction produces very less variations. Asexual reproduction requires only one parent and thus the offspring would be very similar to the parent.
NO LINKS Explain how a knee-j erk reflex occurs.
Answer:
The sensory neuron receive the stimulus by tapping at the knee cap and its going to send the message all the way to the spinal cord. And then it will make a U-turn and they will send the message back to motor neurons and then back to the knee cap so that the muscle will contract and your knee will just kick up.
Explanation:
A blood specimen X is tested with blood group A serum and with B serum, both of which it agglutinate. To which blood group does X belong?
Answer: The blood group X belongs to is blood group AB.
Explanation:
Blood group typing is a process used in blood group serology to safely receive or donate blood during transfusion procedures. Blood groups found in human being can be put into four distinct groups, A, B, AB, and O, according to the antigens and antibodies that are found in the blood. Antigens are found on the surface of the red blood cells, while antibodies are found in plasma.
--> Blood group A: They possess A antigen on their red blood cells and antibody B in the serum
--> Blood group B: They possess B antigens on their red blood cells and antibody A in the serum.
--> Blood group AB: They possess both antigen A and B on their red cells with NEITHER antibody A nor B.
--> Blood group O: They possess neither antigen A nor B on their reb cells but has BOTH antibodies A and B.
In blood typing, we can identify our blood group by mixing a drop of blood with serum containing:
--> Anti- A antibody and
--> Anti- B antibody.
The clumping of red blood cells is called agglutination. The anti - A serum will cause the blood containing red blood cells with antigen A to clump while the anti- B serum would cause blood containing red cells with antigen B to clump. Therefore, specimen X is Blood group AB as the blood group contains both antigen A and B which clumps when added both A and B serum antibody.

How does an increase in the human population affect ecosystems?
A larger human population increases Earth's biodiversity.
A larger human population has a greater need for natural resources.
A larger human population produces more natural resources for living things
A larger human population helps matter cycle through ecosystems more quickly
Answer:
B, A larger human population has a greater need for natural resources.
Explanation:
Biodiversity means the population of something. But humans are using more resources as the human biodiversity increases.
SOOOOO... as the biodiversity of the human population increases, CAUSES us to use resources.
Refer to Animation: Filtration, Reabsorption, Secretion. Cells of the excretory tubule _________water by osmosis, from which we can conclude that the solute concentration in these cells must be _________ than in the filtrate.
Answer:
Remove and lower.
Explanation:
Cells of the excretory tubule remove water by osmosis, from which we can conclude that the solute concentration in these cells must be lower than in the filtrate. The excretory tubule remove excess amount of water from the cell through semi permeable membrane of the cell while on the other hand, the solute concentration in the cell is lower as compared to filtrate so that's why it can't diffuse from the cell by the process of osmosis.
A trace fossil can determine the ______________ of an organism.

It will gradually decrease in size for four weeks.
Answer: B. It will gradually increase in size for approximately two weeks and it will gradually decrease in size for approximately two weeks.
Explanation:
The moon orbits around the earth in 27.322 days. It is the brightest celestial body. It does not shine under own power instead glows with the reflected sunlight. Moon start dark and gets illuminated by the sunlight over the time of two weeks. When moon's disk becomes fully bright it gets fade, again returns to dark in about two weeks.

As you worked down the dichotomous classification key to identify sharks, did you go from general to specific characteristics or from specific to general characteristics? Explain your answer using four characteristics that were used in the shark key.
When constructing a dichotomous key, we should start with general characteristics and then move to more specific characteristics. A dichotomous key lists an organism's structure and behavior so it may be recognized through elimination.
What are four characteristics that are used in the shark key?When attempting to categorize an organism, scientists frequently make use of a dichotomous key. A dichotomous key is a listing of specific features, such as structure and behavior, in such a way that an organism may be identified through a process of elimination. Examples of dichotomous keys include the following:
The shape of the body, the number of gill slits, the position of the mouth, and the shape of the caudal fins are the dichotomous keys for identifying sharks. Other features include the length of the dorsal fins or the number of dorsal fins, the presence or absence of pelvic fins and the shape of the skull.
