Answer:
A)Fixation. Nitrogen in its gaseous form (N2) can't be used by most living things
B) it can not be used because it most be converted or, ’fixed’ to a more useable form. To do this it goes through a process called fixation.fixation is the change in a gene pool from a situation where there exists at least two variants of a particular gene (allele) in a given population to a situation where only one of the alleles remains.
C) This form can be made more usable if it’s converted. It has to go through the process of fixation so the gene pool changes.
Explanation:
Answer:
D) The fungicide will reduce the stability of the ecosystem because nutrients in the soil will be less likely to be recycled, directly impacting plant nutrition and growth.
Explanation:
Fungicide are primarily applied to an area to kill off fungi species in that place.
Fungi are very important groups of organisms. They are natural "recyclers".
In a food chain or web they can be classified as decomposers.
Decomposers are organisms that takes feeds on dead and decaying organic matter.
The produce useful materials and releases nutrients from life back into nature.
Killing them off by applying fungicides is a damaging act to their sustenance.
Without decomposers such as fungi, the ecosystem becomes less stable and soil nutrients will not be properly recycled.
The answer to your question is B, Lunacy.
Answer:
Adrenocorticotropic hormone (ACTH)
Explanation:
During stress condition, the pituitary gland located in the brain receives a stimulatory signal from the hypothalamus and releases the Adrenocorticotropic hormone
.
The Adrenocorticotropic circulate in the brain and when reaches the adrenal gland causes the release of the cortisol and the epinephrine or adrenaline from the adrenal gland cortex.
These two hormones along with norepinephrine acts in the adrenergic receptors and produces the stress response or fight or flight response.
Thus, Adrenocorticotropic hormone is the correct answer.
Polar.
Polar means that it has a negative pole and a positive pole
