Answer:
is this a true or false question
The
correct answer is RNA.

The
central dogma explains the flow of genetic information within a biological
system. It is a simplified explanation for a gene expression. DNA is copied
into mRNA during the process of transcription and the proteins are synthesized
using the information in mRNA during the translation.</span>
Answer:
The correct answer is "Decreased metabolic rate".
Explanation:
The sympathetic division is the part of the autonomic nervous system that deals with the coined "fight or flight" response when facing with a stressful situation. Is not true that when the sympathetic division is activated the metabolic rate decreases, actually, the effect is the opposite. The sympathetic division influences key processes such as glucose and lipid metabolism as well as daily energy expenditure, particularly, it influences the resting metabolic rate (RMR).
Diffusion is essential for cells to bring nutrients and releasing wastes WITHOUT spending energy. This is accomplished by the "urge" of a system to achieve equilibrium, which means that materials tend to flow from high concentration to low concentration area. For example, if a cell lacks amino acids, and therefore has a low concentration of it inside the cell compared to the outside, then by diffusion, the amino acids outside will flow in through the membrane until the concentrations of amino acids outside and inside the cell are the same. All these are done without spending energy from the cell. Note, however, that simple diffusion cannot transport larger particles or those insoluble in lipids; these materials have to be transported with facilitated diffusion, where a carrier on the membrane of the cell will help bring in the materials.
<span>Diffusion is when particles in a more concentrated area move to a less concentrated area, through a semi- permeable membrane. Without diffusion, the cells in your body will not be able to obtain the resources they need to survive, like water and proteins.</span>
