<span>The answer to the question that is being presented above would be K-selected. Sperm whales, which have adapted to live in equilibrium at carrying capacity for a long time, are referred to as the K-selected kind of species.</span>
Sunlight is the main change! sun light cannot penetrate into the deep layers of the ocean and availability of oxygen is also low there. this causes the considerable amount of organisms to live in the upper layers of the ocean and we can only observe decomposing organisms in the deeper layers!
A pedigree shows the genotypes of the family members
in autosomal recessive disorders, the diseased genes are inherited from the parents. For the person to get the disease both diseased genes should be there in the genotype as its a recessive disorder.
the dominant gene - H
recessive gene - h
for a person to get a disease, genotype should be hh, as its autosomal recessive. If the person is normal he/ she could have the genotype HH or could be Hh and thats called a carrier.
the offspring will receive one gene from the mother and one from the father
I assume that in this item, we are asked to solve for the force exerted during the heartbeat. Force is the product of the mass and acceleration. To solve for the acceleration in this item, we divide the velocity by time.
a = 1 m/s / 0.2 s = 5 m/s²
Then, we multiply this by the mass (in kg)
F = (80 g / 1000 g/kg) x (5 m/s²)
= 0.4 kg m/s² = 0.4 J
Therefore, every hearbeat will take 0.4 J of force.
Answer:
True
Explanation:
The Drosophila like the mammals possess X and Y chromosomes but as in males in which the XX is female and XY is male, the sex In Drosophila is not determined by the presence of Y chromosomes as a male determining factor are present on the autosomes.
However, the Y chromosome is important for males as they are involved in the formation of the sperms therefore the presence of Y is important. In the given question if the allele is present ion the Y chromosome which can reduce the size therefore the allele is passed on to the males only ans no females.
Thus, true is the correct answer.
the fly is female (Bridges 1921, 1925). Thus, XO Drosophila are sterile males. In flies, the Y chromosome is not involved in determining sex. Rather, it contains genes active in forming sperm in adults.
