Because the roots are still connected to the grow
Answer:
C. True.
Explanation:
It should be understood that the the percentage of nitrogen is the highest in the atmosphere. This is because, it make up of more than 60% of the atmosphere. And it should be noted that the atmospheric nitrogen is inform that can not be used by the plant.
Therefore, there is a need for a certain group of bacteria which live in the root noodles of the plants to convert the unused form of the atmospheric nitrogen to a form that can be used by the plants.
For Hypothalamo-Pituitary-Adrenal Axis of endocrine gland secretion, follow the root "CORTI" (C). This will be a great memory tool. Also, nearly all hypothalamic hormones that stimulate anterior pituitary secretion have the word RELEASING (hence "R" in their acronyms). So if asked what secretes CRH, GnRH, TRH, or GHRH... the answer will be the Hypothalamus because of the R.
Now... back to CRH... we're following the "C" for CORTI. What other endocrine hormone has C for CORTI??
ACTH = Adreno[Corti]coTropic Hormone
Which will then stimulate secretion of [Corti]sol (a glucocorticoid), amongst others from the cortex of the adrenal gland. Notice the [Corti] follows the whole pathway from Hypothalamus to adrenal Cortex: Hypothal. (CRH) --> Ant. Pituit. (ACTH) --> Adrenal Cortex (Cortisol)
Sorry this was so long-winded, but I was hoping to help you grasp a portion of how the Endocrine System works!
Good luck and hmu should you have any further Anatomy/Physiology questions.
