The patellar reflex can be defined as the kicking movement of the lower leg which occurs with a sudden twitch when the patellar tendon of a person is tapped. This patellar tendon is present below a person's kneecap. This reflex happens only when the leg is bended. It is impossible for patellar reflex to occur if the leg is straight as the quadriceps muscles are already contracted and a sudden kicking movement of the leg in such state could not be elicited. The patellar reflex protects the quadriceps from stretching too much.
Answer:
d. Water is transported in the phloem.
Explanation:
Xylem is the vascular tissue responsible for the movement of water and dissolved minerals from roots to various plant parts. Phloem is another vascular tissue that serves mainly in the translocation of sugars. The cohesion-tension model of water transport explains that the upward movement of water from roots to the aerial plant parts is drive by transpiration pull. Transpiration of water from leaves results in a large negative pressure in xylem elements. Cohesion and adhesion properties of water maintain the water column in xylem elements.

Aquatic nitrate pollution can result in algal bloom that when the algae die and are decomposed by bacteria, leads to hypoxia and the death of fish.
<h3>What is algal bloom?</h3>
Algal bloom is a dense spread of algae on the surface of water.
Algal bloom is caused by a process of eutrophication, which is the release of artificial or natural nutrients, mainly phosphates, through detergents, fertilizers, or sewage, to an aquatic system.
Therefore, it can be said that aquatic nitrate pollution can result in algal bloom that when the algae die and are decomposed by bacteria, leads to hypoxia and the death of fish.
