Answer:
The left side of the heart receives oxygenated blood from the pulmonary vein and pumps it into the aorta, while the right side of the heart receives deoxygenated blood from the vena cava and pumps it into the pulmonary vein. The pulmonary vein and aorta also have valves connecting them to their respective ventricle.
Explanation:
Answer:
In mammals, oxygen is carried through the red blood cells called hemoglobin. The reason is that the oxygen is very important for the cell for releasing energy. This energy is used by the cell in different processes.
2) These adaptations are adapted by the organisms in order to perform different functions. In slow twitch skeletal muscles having high number of mitochondria because it requires more energy while fast twitch skeletal muscles contains less amount of mitochondria due to low requirements of energy. These characteristics are adapted according to the performance of the body parts.
Answer:
0.095
Explanation:
Phenylkentonuria is a disease caused by a recessive allele.
The frequency of the recessive allele + the frequency of the dominant allele equals 1.
The frequency of the recessive allele is q = 0.05
The frequency of the dominant allele then is p = 1 - q = 0.95
If people mate randomly, the frequency of the homozygous dominant genotype will be p², the frequency of the heterozygous genotype will be 2pq and the frequency of the homozygous recessive genotype will be q² .
2pq=2× 0.05 × 0.95
2pq=0.095
The heterozygote frequency in the population is 0.095
