An animal that does not have the traits to adapt to its surroundings will?

Answers

It may become endangered

Explanation: If organisms cannot adapt to the changes in their ecosystem, they may move to another location. If they will not move, the species may become threatened, endangered, or extinct. Under an evolutionary phenomenon called relaxed selection, traits that were advantageous in one time and place become obsolete in another. Traits that aren't actively maintained by natural selection tend to become smaller or less functional over time, studies suggest.

During the retreat of a glacier, pebbles and bare rock that were under the sheet are exposed to the air. What is likely the next event to occur?
( don’t mind the blue dot )

Answers

I think it’s cause About 200 years ago, the glaciers started melting, which scientists call "glacial retreat." With the retreat of the glaciers, ridges of rock and debris called moraines remained. Moraine is little more than bare rock and no plant life can exist on it until the first stages of succession begin.

what property of greenhouse gas make them important Earth's temperature?

Answers

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.

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?

Answers

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.

Why do traits increase within a population over time

Answers

Gene duplication, mutation, or other processes can produce new genes and alleles and increase genetic variation. New genetic variation can be created within generations in a population, so a population with rapid reproduction rates will probably have high genetic variation.

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.

Answers

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.

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.

Answers

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.

What conclusion can you make regarding how humans affect biodiversity? Is evidence from the graph to support your answer

Answers

Answer:

Decrease population of staghorn coral and spotlight parrot fish.

Explanation:

Humans greatly affects biodiversity by decreasing the population of most of the organisms due to its activities. Human activities causes pollution in the environment as well as disturbed the habitats of many organisms that leads to  decrease in their population. Humans activities releases carbondioxide gas in large concentration that will leads to the increase of pH of the ocean water which adversely affected the population of many marine animals such as staghorn coral and spotlight parrot fish etc so that's why we can say that human activities adversely affected biodiversity.
