Answer:
b) from a region of high pressure to a region of low pressure
Explanation:
Blood flow is measured in blood volume per unit time. It is the movement of blood through an organ, tissue or vessel. It is initiated when ventricles in heart contract leading to its ejection at high pressure. Major arteries receive this blood and they further transport it at high pressure to smaller arteries, arterioles and capillaries. Hence arteries have thick walls to withstand this pressure. The pressure decreases when blood reaches to veins hence their walls are not that thick. Hence, blood flows from a region of high pressure to a region of low pressure.
Answer:
C. tend to be transmitted together.
Explanation:
Independent assortment of alleles of the genes during anaphase-I of meiosis-I requires that the genes should be present on different chromosomes. The genes that are present on the same chromosomes deviate from the independent assortment. These closely placed genes are called linked genes. They move from one generation to next together and do segregate randomly. This results in the generation of more proportion of the parental types in the progeny. The linked genes may be present on both autosomes and sex chromosomes.
