Answer:

The correct answer is 4. D and E

Explanation:

Organisms are divided into seven major levels of classification and these are Kingdom, phylum, class, order, family, genus, and species. The highest level here is the kingdom and the smallest level is species.

If we move from kingdom to species the structural homology increase and when we move from species to kingdom structural homology and relatedness decreases.

Therefore as class is higher domain than order so the organism in order will show more degree of structural homology with each other than class therefore the correct answer is 4.

Drinking alcohol can cause dehydration, which makes the blood hypertonic. Which option best describes the consequences of this h
julsineya [31]

Answer:

Hypertonic blood draws water out of the interstitial fluid, which makes the interstitial fluid hypertonic. This, in turn, draws water out of the cells.

Basically an hype tonic blood has high solute potential,( low water potential)  compare with  the surrounding  plasma  and the interstitial fluid. Thus the interstitial fluid is hypotonic to the blood.

Consequently,water with higher potential moves   from the interstitial fluid medium into the blood by osmosis through the capillary endothelial. This raises the water potential of the blood, lowering the solute potential, thus making it hypotonic to the interstitial fluid; which is now hypertonic(lower water potential ,due to loss to the blood by osmosis).

Since the interstitial fluids is now hyper tonic to the surrounding cells, water moves from the hypo tonic surrounding cells through osmosis into the interstitial fluids. The sequence continues until a stable internal environment is achieved,

Based on the model explain whether the molecules shown crossing the membrane require energy to do so
Svetach [21]

Answer:

As the diagram is not given, hence let's generally describe the movement of molecules along the cell membrane.

Molecules can either pass through the cell without using energy through the process of passive transport. An example includes molecules of oxygen.

Molecules which are large and un-polar cannot move through the cell membrane easily. These molecules will require energy to move through the cell membrane. These molecules might move in with the help of the carrier or facilitated proteins. Examples include molecules of glucose.

Apart from suffering from recurrent and prolonged infections, Marie Curie also experienced the following signs and symptoms: fat
Nataly [62]

Answer:

See below

Explanation:

Marie Curie died of aplastic anemia in 1934. Aplastic anemia is an autoimmune disease in which the body fails to produce blood cells in sufficient numbers. Blood cells are produced in the bone marrow by stem cells that reside there. Aplastic anaemia causes a deficiency of all blood cell types: red blood cells, white blood cells, and platelets.

Fatigue is a symptom of aplastic anemia as the blood doesn't have the necesarry red blood cells to transport the oxygen to the organs.

Rapid heart rate happens because the body senses the decrease of oxygen's concentration and the hearts beats faster to provide the organs of oxygen.

Pale skin happens because the blood vessels are contracted in order to provide oxygen to the important organs of the body as the brain and heart. It means that less blood reaches the face and it shows as pale skin.

Prolonged bleeding from cuts happens because there aren't enough platalets to produce a blood clot to stop the bleeding.

Dizziness happens because there is not enough oxygen arriving to the brain.

If she is A negative, she can only receive blood from others A negative donors, or O- donors. This is because she has antibodies to B, and to groups that have the protein Rh (+). So she can't receive blood either B nor Rh+.

How does the structure of a type of human tissue relate to its function in the body?
Illusion [34]
I'll give the example of muscle tissue. The arrangement of cells in muscle tissue allows for contraction and relaxation with elasticity, as the tissue is smooth. The answer will be different depending on which type of tissue you are looking at.
