Anolis cristatellus and A. cooki are both trunk-ground anoles that live on Puerto Rico. A. cristatellus lives in a shady, forest

environment, while A. cooki lives in an open, sunny environment. What is an adaptive explanation for why the dewlap of one species evolved to be brighter and that of another species darker?

Answer:

The answer is for reproductive reasons.

Explanation:

The anolis cristatellus has a brighter dewlap and the anolis cristatellus has a darker dewlap. Their dewlap contrasts the brightness of their environment, most likely because it stands out more and attracts more female anoles.

The semilunar valves of the heart open at the onset of the ejection period. Approximately what percentage of the stroke volume i
mr Goodwill [35]

The percentage of the stroke volume is ejected during the first quarter of systole will be approximately 60% to 65%

<u>Explanation:</u>

The time interval between the atria contraction and the relaxation of ventricles are called as a Cardiac cycle. Systole denotes the heart contraction during the blood pumping. Diastole refers to the heart relaxation when the blood is filled in the heart chambers. The total blood is not fully pumped by the ventricles.

Instead they will pump only a proportion of blood in each of the cardiac cycle.  The ejection fraction refers to the proportion of the intraventricular volume that is received as a output in circulation process. A human with normal heart functioning can have approximately 60-65%. This is known to be stroke volume. The blood volume that is ejected is strove volume.

What are the 2 ways plants use energy?
Alex777 [14]

Answer:

What are the 2 ways plants use energy?

Explanation:

This process uses solar energy to convert carbon dioxide and water into energy in the form of carbohydrates. It is a two-part process. First, the energy from solar radiation is trapped in the plant. Secondly, that energy is used to break down carbon dioxide and form glucose, the main energy molecule in plants.

plasma cell differentiation, antibody quality, and initial germinal center b cell population depend on glucose influx rate
garri49 [273]

In secondary lymphoid tissues, germinal centers (GCs) are created after exposure to T-dependent antigens.

As a result of somatic hypermutation, B cells with higher antibody affinities are produced in GCs. These high-affinity B cells then preferentially develop into plasma cells, which reside in the bone marrow and provide long-lasting humoral protection.

The physiological and molecular basis for starting the shift from a GC B cell to a plasma cell has been newly illuminated by recent investigations. Here, we review recent developments in our knowledge of how the GC response regulates the production of plasma cells in order to produce long-lasting protective immunity and avoid damaging autoimmunity.

The terminally developed B lymphocytes known as plasma cells release antibodies on a regular basis. These antibodies can defend against infections, and the greatest clinical correlates of vaccine effectiveness are their amount and quality.

Therefore, the plasma cell lifespan plays a major role in determining the duration of humoral immunity. However, autoimmune disorders or multiple myeloma can result from a breakdown in plasma cell activity. The primary determinants of plasma cell longevity are food intake and metabolic processes that are not transcriptionally regulated.
