Answer:
a. The embryo would suffocate or dehydrate.
Explanation:
Chorion is one of the four extraembryonic membranes that cover the embryo inside the egg. Chorion develops into the part of placenta-derived from the fetus.
Trophoblast develops into chorion during pre-embryonic development. Once formed, the chorion develops villi that are required for the exchange of material, specifically the respiratory gases, between the mother and fetus.
If an egg had nonfunctional chorion, the developing embryo will not get the supply of gases. In the absence of gas exchange between mother and embryo, the embryo will die of suffocation.
Chorion is also involved in the development of the placenta which in turn is the organ of the exchange of nutrients and gases and removal of toxic material.
Nonfunctional chorion would not support the placenta formation and the embryo will not get the supply of nutrients and water.

Answer:
0.483
Explanation:
The given population is in Hardy-Weinberg equilibrium. If the gene has two alleles, the sum total of the frequencies of these two alleles will be one.
Therefore, the total of the frequency of allele B and frequency of allele b will be 1. f(B) + f(b)=1
If the frequency of allele "B" is 0.59, then the frequency of allele "b" will be=1-0.59= 0.41
The frequency of heterozygous genotype in the population= 2pq
p= frequency of the dominant allele
q= frequency of the recessive allele
So, 2pq= 2 x 0.59 x 0.41 = 0.483
Answer:
Circulatory system remove waste from the cell and provide clean blood to the cell.
Explanation:
During cellular respiration, lungs inhale oxygen which stored in the alveoli. The red blood cells contains hemoglobin that carries deoxygenated blood containing carbondioxide from the cell in the veins to the heart and unload this carbondioxide gas in the alveoli of the lungs and load oxygenated blood having oxygen from the alveoli through capillaries in order to provide oxygen to the cells that is necessary for the survival of humans. Platelets are the type of cells that helps in blood clotting whereas white blood cells provides immunity against pathogens.
