Basically all of the choices given are failure of negative feedback mechanisms to maintain homeostasis. The correct option among all the options that are given in the question is the last option or option "E". I hope that this is the answer you were looking for and it has come to your help.
Answer:
Nucleic acids are the most important macromolecules for the continuity of life. They carry the genetic blueprint of a cell and carry instructions for the functioning of the cell. The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
Explanation:
dang it.
Answer:
Like with fingerprints, no two people have the same brain anatomy, a study has shown. This uniqueness is the result of a combination of genetic factors and individual life experiences. Like with fingerprints, no two people have the same brain anatomy, a study by researchers of the University of Zurich has shown.
According to Darwin's Theory of Natural Selection, each generation produces more individuals than the ecosystem can sustain. However, not all individuals are identical and phenotypical variation exists.
Due to this variation, some antelopes are better at escaping lions, perhaps due to speed and/or stamina. Thus, the individuals that are slower and thus less fit will be killed and eliminated from the herd. The antelopes with heritable traits that makes them better suited to the environment, will escape and thus, survive and reproduce.
In Darwin's Theory predation is an evolutionary force.
2) Chemical substances in food dissolve in saliva
Substances form the food need to be dissolved and and a little bit degraded (by teeth and some of the enzymes in the mouth) in order to react chemically with taste receptors
1) Taste receptors are stimulated
Taste receptors are located in the oral cavity, usually on the tongue but also pharynx and the epiglottis (receptors are placed on taste buds within papilla on tongue)
3) Signals are sent to the thalamus by the facial nerve
From the ventral posterior medial nucleus in thalamus sensation is projected to the gustatory cortex
4)The gustatory cortex processes taste perception
The sensation of taste includes: sweetness, sourness, saltiness, bitterness, and umami
