Answer:
The correct answer would be B) the flow of water through the body of a sponge.
Sponges are multi-cellular organisms which are devoid of organ systems like digestive system, nervous system, circulatory system et cetera.
They have a unique feeding system in which they keep constant water flow through their bodies. They obtain food and oxygen and remove waste through this water movement.
The movement of water throughout the sponge is unidirectional in nature. It enters the sponge body through ostia and exit from the osculum.
As the water is pumped out, the cells present in the walls filter out the food present in the water.
The cell membranes begin to come apart when there is insufficient water around the cells. The cytoplasm of the cells becomes more concentrated, which slowly poisons the cells. The cell walls become brittle as they dry out, and some of them collapse. The central vacuoles in the cells lose water and can no longer help support the cells.

The answer is B) ATP production begins with glucose.
Thigmotropism is a directional growth movement of curvature which occurs in response to stimulus of contact. Thigmotropism is found in twiners and tendrils. After initial contact with support due to nutation, the tendril or twiner shows less growth in the region of contact and more growth on the other side. As a result they bend over the support.
