The CNS are lined by ependymal cells. Ependymal cells are epithelial cells that monitor the composition of cerebrospinal fluid (CSF)
The correct answer should be
<span>D. Autonomic nervous system
It is called autonomic because it works on its own and it regulates organs functioning which is a thing that happens involuntarily. It regulates heart beats for example and it's not something that you do voluntarily since the heart beats regardless of you. It also controls things like vomiting or sneezing that you can't choose not to do when it starts happening.</span>
Answer:
The citric acid cycle is fundamental to produce the energy needed for aerobic cell metabolism, thereby mutations in the enzymes involved in this metabolic pathway would be lethal to the individual
Explanation:
In aerobic organisms, the citric acid cycle (also known as the Krebs cycle), is a key metabolic pathway used to remove electrons and uses them in the electron transport chain in order to generate adenosine triphosphate (ATP), the energy currency of the cell. The citric acid cycle depends on eight enzymes that oxidize acetyl-CoA into two molecules each of carbon dioxide (CO2) and water (H2O). Thus, the citric acid cycle is a series of chemical reactions that are key to breakdown carbohydrates, fats and proteins into CO2 and H2O in order to produce energy (ATP).
Hello. The chart mentioned in the question above is attached just below.
Answer:
A) has increased with increasing human population
Explanation:
As you can see in the graph below, the line that indicates the number of endangered species increases as the line that represents the increase in the human population increases. This means that the number of extinct species has increased with the increase in the human population.
This is because with the increase in the human population, there is a growing need for natural resources, in addition to increasing the need for cities to expand. All of this results in greater deforestation and extraction of natural resources, which ends up causing an increase in the factors responsible for the extinction of animals.
