Answer:
B. decreases salivation and increases blood pressure
Explanation:
The sympathetic nervous system is part of the autonomous nervous system which controls involuntary responses of the body such as salivation and blood pressure.
The sympathetic nervous system is majorly responsible for body actions that are produced when threat is perceived. It generates responses referred to as the “fight or flight” response. Examples of such responses include, increased breathing, increased high blood pressure, dilation, decreased salivation, etc.
Activation of the sympathetic nervous system would result in rise in the blood pressure as can be witnessed by someone whose body has perceived a threat or reacting to a stressful situation.
The control of salivary production by the sympathetic nervous system leads to the release of noradrenaline which acts on certain receptors that results in decrease in the production of saliva. This is evident in a person that is facing a threat also.
Answer:
The correct answer is a. messenger RNA
Explanation:
The plasma membrane mainly contains lipids, proteins, and carbohydrates. Phospholipids make the bilayer of the plasma membrane. Carbohydrates can be found attached to proteins and lipids.
The carbohydrates that are attached to lipids are called phospholipids and those with proteins are called glycoproteins. mRNA is the molecule which is not the part of the plasma membrane. mRNA is produced in the nucleus through the transcription process and is responsible for proteins formation.
So phospholipids, glycolipids, and glycoproteins are the part of the plasma membrane but not messenger RNA.

38 chromosomes
<span>The two identical daughter cells resulting from mitosis and cytokinesis are identical in the following ways:1. Mitosis occurs when the nucleus of the cell divides into two identical nuclei, each with the same type and number of chromosomes. The cell's DNA is duplicated during this phase. Sometimes the cell's DNA isn't copied properly resulting in cancer-type cells. 2. Cytokinesis is when the cytoplasm divides into two identical daughter cells. Each cell is genetically identical and both are a similar size. </span>
