Answer: Shoot of plants is positively phototropism.
Explanation:
The response in view is phototropism. The shoot of plants are positively phototropic , meaning that it moves towards the source of light.
The mechanism here is that Auxins, a growth hormone that are produced at the meristematic cells at the apices of the shoot and the root especially in young plants shy away from the source of light. So if a potted plants is kept in a dark room with only a small source of light, the Auxins at the tip of the shoot will move away from the side of the plant facing the source of light.
Because Auxins is a major plant hormone, it will induce a rapid growth on the side it has accumulated hence cause the shoot of the plant to bend towards the source of light and respond positively to the light stimulus.
The response is an adaptation for the plant because green plants need light (solar) to produce their food through the process of photosynthesis. Absence of light will negatively affect the survival of the plant.

Woman's genotype is AO
Man's genotype is BO
The can have a child with blood group A, B, AB and O
1/4 will have type AB blood group;
1/4 will have AO, which is type A blood group;
1/4 will have BO, which is type B blood group;
1/4 will have OO, which is type O blood group
