Answer:
promote stomatal closure during drought stress.
Explanation:
Abscisic acid inhibits the growth and stomatal opening, specifically when the plants are exposed to some stress conditions. Abscisic acid also regulates the seed maturation and seed dormancy. ABA concentration in leaves increases multiple folds under drought conditions. Its accumulation in leaves promotes closure of stomata and prevents the water loss by transpiration. ABA is required to restore the turgor pressure under drought conditions by stimulation of stomatal closure.
I think the answer is naturally acquired active immunity..also depends on which disease
Answer: mitosis
Explanation:
Mitosis is the process when a parent cell is divided, and two daughter cells are found after the process. This question says that when the parent cell is split, two daughter cells are the result. This is mitosis, so the answer is D.
It represents the cycle of life, because a tadpole should turn into a frog.
Answer:
Myelin sheath
Explanation:
Myelin sheath cover the axon of neurons and act as insulator for the faster transmission of signals.
Each axon is covered by multiple myelin sheaths and the gap between myelin sheath are known as Nodes of Ranvier.
In CNS myelin sheath is composed of glial cell called as oligodendrocytes and in PNS the myelin sheath is composed of Sachwann cells (glial cells).
