Answer:
Following are the solution to this question:
Explanation:
Consider its nucleotide that many of the time arrives to suggest a binding site. For example, nucleic acid A comes four hours at the place-100th, mostly on the list. Consequently, A would be the -100th nucleic acid. The following was its pattern:
Answer: False
Explanation: They are replaced every seven years
Explanation:
When blood glucose levels increase above set point, the hormone insulin, which is produced in the beta cells of the Islets of Langerhans in the pancreas, is secreted into the bloodstream. The insulin binds to insulin receptors on cell membranes of liver cells, which results in accelerated conversion of glucose to glycogen, and a slower conversion of glycogen to glucose. This caused blood glucose levels to fall back to normal range again.
<h2>a,d,b,c is the correct order</h2>
Explanation:
Before oxygen is picked up in the lungs by hemoglobin, it first diffuses through (a) alveolar cells,d) capillary walls (b) blood plasma, (c) red blood cell plasma membranes
- Although oxygen dissolves in blood, only a small amount of oxygen is transported this way,1.5 percent of oxygen in the blood is dissolved directly into the blood itself and most oxygen—98.5 percent—is bound to a protein called hemoglobin and carried to the tissues
- Hemoglobin (Hb) is a protein molecule found in red blood cells (erythrocytes) made of four subunits: two alpha subunits and two beta subunits
- Each subunit surrounds a central heme group that contains iron and binds one oxygen molecule, allowing each hemoglobin molecule to bind four oxygen molecules
- Molecules with more oxygen bound to the heme groups are brighter red because of which oxygenated arterial blood where the Hb is carrying four oxygen molecules is bright red, while venous blood that is deoxygenated is darker red
- At the same time, carbon dioxide that is dissolved in the blood comes out of the capillaries back into the air sacs, ready to be breathed out
- Oxygenated blood travels from the lungs through the pulmonary veins and into the left side of the heart, which pumps the blood to the rest of the body
- Oxygen-deficient, carbon dioxide-rich blood returns to the right side of the heart through two large veins, the superior vena cava and the inferior vena cava
- Then the blood is pumped through the pulmonary artery to the lungs, where it picks up oxygen and releases carbon dioxide
The main goal of ecological succession is "development of new species".
<u>Option:</u> A
<u>Explanation:</u>
The mechanism of transformation of an ecological community's species structure over time is understood as "Ecological succession". The timeframe can be decades like a wildfire after a mass extinction, or even millions of years.
Succession can either be caused by the development of new, unused habitat, perhaps from a lava flow or a severe landslide, or through some form of community disruption, such as from a fire, extreme windthrow, or deforestation. It is not in equilibrium as a group undergoes numerous changes across each stage of succession.
