<span> How does pulmonary circulation work? In my example below, we will start with the blood not reaching the heart yet. The heart beats around 75 beats a minute. Deoxygenated blood is in the veins, going to the heart. Note that veins will always carry deoxygenated blood, excluding the pulmonary veins. The deoxygenated blood goes into the heart through the superior or inferior vena cava, and goes into the right atrium. It then gets pumped into the right ventricle, and gets pumped through the pulmonary arteries to the lungs to get oxygenated. The blood, now oxygenated, comes back to the heart through the pulmonary veins, into the left atrium. The blood gets pumped from the left atrium to the left ventricle, where it gets pumped through the aorta to all of the body systems. The red blood cells travel through capillaries, which is where most of the gas exchange occurs between body cells and red blood cells. Red blood cells have no nuclei. When the red blood cells are no longer red, but blue due to lack of oxygen, they go back to the heart to get pumped to the lungs, and enter the heart through the superior or inferior vena cava. The cycle starts over. Just like the veins, arteries always carry oxygenated blood, excluding the pulmonary arteries. Also, the right side of the heart will have deoxygenated blood, or blue blood, and the left side of the heart will have oxygenated blood. </span>
Answer:
The correct answer will be option-The red and white flower alleles are co dominant.
Explanation:
The Mendel suggested that for any trait, the organism contains its alleles which could be dominant and recessive. But there are cases in which multiple alleles exist for the same trait which are neither dominant nor recessive.
Two cases arise due to this in which both the dominant alleles co-exist and show their phenotype effect called "co-dominance" and when both alleles form a new phenotype called 'incomplete dominance".
In the given case, the self-pollination produces red, white and patched flowers as a result of co-dominance because both the alleles show the equal effect on the flower petals (mixed phenotype) and form a flower with red patches or spots on the flower.
Thus, the selected option is the correct answer.
Answer: C.
Explanation: science involves data of the natural world and is gathered everyday which makes different observations b
I would say either A or B
The Greenhouse Effect is the process in which the earth's surface if warmed when the sun's energy enters the earth atmosphere and is retained by the greenhouse gases in the earth's atmosphere. The rest of the radiant heat that didn't make it past our atmosphere is reflected into space.
