<span>Land snails, semi-slugs and slugs are important players in the forest decomposition process and contribute to the nutrification of soils through their decaying bodies, shells and faeces. Their dead shells can form an important source of calcium for other animals in calcium-poor habitats.</span>
YOUR ANSWER IS tRNA because the mRNA sends out a message to the tRNA and the tRNA brings back the appropriate amino acid but if the tRNA where to bring back the wrong the protein could fold incorrectly.
At an inhibitory synapse (IPSP), the postsynaptic membrane experiences all of the above and is denoted as option B.
<h3>
What is Hyperpolarization?</h3>
This is described as the opposite of depolarization and involves the cell's membrane potential being more negative.
At an inhibitory synapse (IPSP), the postsynaptic membrane becomes hyperpolarized which is characterized by an increase in permeability to both Na and K.

#SPJ1
Answer:
Option A
Explanation:
As per the principle of intrinsic fitness, a person likes to work for his/her inner satisfaction driven by motivation within him/herself.
Thus, a young bird which feels an urge to produce chicks by mating each year will ultimately go outside to find his/her mate on their own and will produce chick every year. In an intrinsic behaviour the rewards achieved are internally self satisfying and thus a person need no assistance in achieving them on their own.
Thus, option A is correct.
Answer:
alarm reaction
Explanation:
In Selye's general adaptation syndrome theory of stress, the initial response of the autonomic nervous system to a stressor occurs in the alarm reaction phase.
The Alarm Reaction is subdivided into two states, the shock phase and the counter shock phase. The physiological changes in the shock phase, when the individual experiences the stressor stimulus, are very exuberant.
During the Alarm Reaction the so-called Autonomic Nervous System (ANS) actively participates in the set of physiological changes. The ANS is a complex neurological ensemble that autonomously controls the entire internal environment of the body through activation and inhibition of the various systems, viscera and glands.
Also during the moment of acute stress stimulation (Alarm Reaction Shock Phase), a part of the Central Nervous System called Hypothalamus promotes the release of a hormone, which in turn stimulates the pituitary gland (which makes part of the hypothalamus) to release another hormone, ACTH. The latter gains the bloodstream and stimulates the adrenal glands for cortisol secretion.
