Answer:
The use of left arm is more compared to right hand
Explanation:
In the given question, the anthropologist when examines the left and right arm he found that the left arm is thicker than the right arm.
The more thickness of the left arm signifies that the person uses his left arm for the muscular work as the more use of hand increases the deposition of the calcium phosphate and sulfate in bones along with other material which increases the thickness for the bones and increases the strength.
Thus, The use of the left arm is more compared to the right hand is correct.
Answer:
The correct answer is A. autosomal recessive
Explanation:
In an autosomal disease, the mutation occurs in the autosomal chromosome, not in the sex chromosome. In autosomal recessive disease if both the defected allele from parent comes in the child then only the child would be affected by the disease. If the offspring have single defected allele than he is said to be a carrier.
So as the defect is not in sex chromosome the disease will occur in the same frequency in both the sexes and if parents are carriers which means they are not affected by disease than 25% offspring can have the disease because out of four offspring one can get both the defected allele, one from each parent. So the correct answer is A.
Answer:
c
Explanation:
plants create growth by converting sunlight into energy, but all organisms need cellular respiration
Both gymnosperms and angiosperms have vascular tissue that is specialized for transport of minerals, water, and organic compounds. Also, both gymnosperms and angiosperms have seeds. The only difference is that angiosperms have seeds hidden in the ovary while gymnosperms have seed on the surface of the scales of the cones.
During interphase, cell growth occurs
