Answer:
<em>B. Nitrogen controls the rate of productivity within an ecosystem.</em>
Explanation:
B) Diploid - Only Gametes are Haploid. Every other cells are somatic cells which are diploid. They contain 46 chromosomes rather than 23 that the haploid carry. Neurons and glial cells make up of the brain and that makes up the nervous tissue. Just remember Gametes (sex cells) are the only cells that are haploids.
Photosynthesis occurs in the chloroplast of algae and plants. Details about photosynthesis can be found below.
<h3>What is photosynthesis?</h3>
Photosynthesis is the process whereby green plants and algae produce food molecules by themselves using energy from sunlight.
Photosynthesis occurs in a compartment of a cell called chloroplast and it harbors a pigment that traps sunlight called chlorophyll.
Therefore, photosynthesis occurs in the chloroplast of algae and plants.

<span> answer: poor regulation of the brain's locus </span><span>ceruleus may lead to panic attacks</span>.
Locus ceruleus is a nucleus in the pons involved with physiological responses to stress and panic. When there is stress he responds by increasing norepinephrine (NE) secretion, which is a critical
regulator of numerous activities from stress response. Panic attacks result from alterations to NE.
Flow through the heart:
Blood enters into the heart through the Superior and Inferior Vena Cava into the Right Atrium. Then from there goes through the Tricuspid Valve into the Right Ventricle, then through the Pulmonary Valve into the Pulmonary Artery and out of the heart to the lungs. Then enters back into the heart through the Pulmonary Veins and into the Left Atrium then through the Mitral Valve down to the Left Ventricle. From there pumps through the Aortic Valve into the Aorta and out to flow throughout your body.
The simple way of explaining the flow throughout the body:
It flows out of the Aorta through Arteries that take your blood throughout your body. The Descending Aorta is large and carries blood downward into more arteries that flow through all of your organs and down to your Pelvic Region to the Iliac Artery and down through your lower extremities through the Femoral Artery. Then there's the Carotid Artery that takes the blood up from the Aorta to our neck and brain. and goes into the arms through the Subclavian Artery. Once it does all this it transfers back from the arteries to the veins. The blood from the arteries goes into little arterioles which is connected to small capillaries and on the other side of those capillaries are Venules which connect to the veins. Then blood is draw into the heart from the veins and the process starts all over again. Crazy that all of this happens each time you feel you feel your heart beat.
