Blood type is coded by two alleles, which have three possible type: A, B and O. The O alleles is recessive, so you need two O allele(from both parent) to have type O blood child.
A person with type AB blood type allele should be one A and one B, so it is impossible to get O allele him.

Answer:
D) 0.04
Explanation:
Assuming that a is the recessive allele when homozygous that causes the polycystic kidney disease and A is the dominant one:
Since Penelope's sisters has the disease, she must be homozygous recessive (aa). Her parents must both be Aa (otherwise her sister wouldn't have inherit the disease). So, the probability of Penelope of being heterozygous (Aa) is 0.5.
On the other hand, the probability of having the disease in the population is 0.04 (1 minus the probability of not having the disease which is 0.96). This, according the Hardy–Weinberg principle, in the population would represent the genotype frequency . So, the allele a would have a frequency
=
= 0.2. Since the gene has only two alleles, all alleles must be either A or a , therefore p + q = 1. So, the A population's frequency is p = 1 - q = 1 - 0.2 = 0.8.
The European man's probability of being Aa (doesn't have the disease but can carry the disease allele) is 2pq = 2 x 0.8 x 0.2 = 0.32.
The probability of Penelope and the European man of having an ill kid (assuming they both are Aa) is 0.25.
Finally, given the Penelope's probability of being Aa (0.5), the European man's 's probability of being Aa (0.32) and the probability of having a kid homozygous recessive aa (0.25) = 0.5 x 0.32 x 0.25 = 0.4 is the probability that they will have a child with ARPKD.

Answer:
c. The pharynx
Explanation:
The pharynx is a tubular organ that begins in the funnel-shaped neck down the neck, extending from 12 to 15 cm in length and about 35 mm at its onset and about 15 mm at the end. its ending. It has communication with the esophagus, nasal passages and the ears. The pharynx is located behind the nasal passages and in front of the cervical vertebrae, remains attached to the larynx and esophagus.
Simply put, we can say that the pharynx is a funnel-shaped passageway that connects the nasal and oral cavities to the "voice box," also known as the larynx.
Answers
Answer:
0.01%
Explanation:
According to the ten percent rule of energy transfer, whenever energy is transferred from one trophic level to a higher trophic level only 10% of total energy available at the lower level gets transferred to a higher one.
Therefore, when the energy is transferred along with the food chain:
grass → grasshopper → mouse → snake → hawk, from grass to hawk there is a loss of 10% of energy at each level.
Therefore, the hawk only gets 0.01% of the energy from the grass.
Answer:
The best answer is Grass. The grass is photosynthetic, which means grasses make their energy from the sun. About 10% of this total energy is available to other organisms in the food chain.
