Answer:
Explanation:
Interphase is composed of G1 phase (cell growth), followed by S phase (DNA synthesis), followed by G2 phase (cell growth). At the end of interphase comes the mitotic phase, which is made up of mitosis and cytokinesis and leads to the formation of two daughter cells.
Answer:
Poorly; his digestive system is not breaking down starch molecules into glucose.
Explanation:
His starch molecules are high while his glucose is low which means that his starch molecules are not breaking down into glucose.
Answer:
Bull = Pp
Cow A = pp
Cow B = pp
Cow C = Pp
Explanation:
In cows polled (P) is dominant over horned (p) trait.
The bull is polled so it can be PP or Pp. Cow B is horned so it must be pp. Resultant offspring from bull X Cow B is also a horned calf (pp). This calf must have received one p from the bull. So the bull's genotype is Pp.
Cow A is also a horned cow so it must be pp. When bull X Cow A, a polled calf is produced. Since the bull's genotype is Pp and Cow A's genotype is pp, this polled calf will be Pp like the bull.
Cow C is polled like the bull so it can be PP or Pp. However on crossing with the bull (Pp) a horned calf is produced (pp). This calf got one p allele from the bull and p allele from the Cow C. So Cow C's genotype must be Pp.
Hence,
Bull = Pp
Cow A = pp
Cow B = pp
Cow C = Pp
<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:
Natural selection is the process where organisms that are mostly adapted to their environment survive and pass on their genetic traits in generations.
