Answer:
A. 0
Explanation:
Both red-green color blindness and and shape of hairline are independently assorting genes.
Red-green color blindness is X-linked recessive while hairline shape is autosomal dominant.
The man who has widow's peak had a father with straight hairline. This means that the man is heterozygous for the trait.
Assuming hairline shape is represented by S. A heterozygous widow's peak man will have a genotype of Ss. A straight hairline woman will have a genotype of ss.
Assuming the allele for colour blindness is c. A normal vision man will have the genotype while a color blind woman will have the genotype .
x
<em>The man does not have the color blind allele and a daughter will need two color blind alleles (one from the father and the other from the mother) in order to show the trait.</em>
<em>This means that the probability of the couple producing a color blind daughter is 0. Hence, the chance that any daughter the couple has will be color blind with a straight hairline is also 0.</em>
The correct option is A.
Answer: "The synovial fluid in my joint capsule acts as a lubricant and helps the movement of the joint's articulating surfaces."
Explanation:
Synovial fluid is also called Synovia. It is produced by the synovial membrane. It is a thick liquid found in the cavities of synovial joints. It's function is to reduce friction by acting as a natural lubricant between the articular cartilage of synovial joints and allows ease of movement, they act as shock absorber and nourishment in the joints. Each of the joints contain synovial fluid.
The answer to the problem is surface zone
Answer:iii. 6
Explanation: the RBC will enter from the superior vena cava into the right atrium then enters the right ventricle. Then it goes into the lungs through pulmonary artery from lungs it enters the left atrium through pulmonary vein and then enters the left ventricles and from left ventricles it enters the aorta.
