Why do you think plasmids and bacterial cells are such important tools in genetic engineering

Masja [62]

In my point of view plasmids allow the genetic transfer of DNA so We can also genetically altered the plasmids to do what we want.

What are the dangers to the nervous system and consequences for a person's health while using ecstasy?

salantis [7]

Answer:

Effects of Ecstasy on the nervous system:

- stimulant

- psychedelic

- neurotoxic

- abnormal neurotransmitter function

- injured cognitive functions (e.g., sleep and pain control)

Explanation:

Ecstasy, also known as MDMA (3,4Methylenedioxymethamphetamine), is a stimulant and psychedelic drug that may exhibit neurotoxic effects. This amphetamine analog (i.e, drug based upon the amphetamine structure) has several effects on the nervous system which are caused by the increase in the activity of three major neurotransmitters: serotonin, dopamine, and norepinephrine. It has been shown that Ecstasy alters the central nervous system, producing neurotoxic effects and affecting brain functions including, among others, cognitive functioning and development, neuroendocrine release mechanisms, sleep control, pain control, etc.

Why is your respiratory system necessary for your body to live

Sonja [21]

Answer:

The respiratory system is necessary for an organism's body to live because it introduces oxygen-rich air, which is needed to perform vital functions, while at the same time promoting the elimination of carbon dioxide.

Explanation:

Oxygen (O₂) is necessary for life because it participates in the process of cellular respiration, a mechanism that allows the oxidation of glucose to form energy in the form of ATP.

The respiratory system is made up of a set of organs that carry air into the body and facilitate gas exchange, i.e. the entry of O₂ into the blood and the elimination of potentially harmful carbon dioxide (CO₂).

This exchange of gases occurs in structures called pulmonary alveoli, whose surface is located in relation to the pulmonary capillary vessels.

The entry of air into the lungs brings O₂ to the alveoli, which will diffuse into the pulmonary capillary for the process of hematosis or oxygenation of the blood.
CO₂, a product of metabolism, leaves the capillary to the alveoli, to join the air that will be expelled during expiration.

Both O₂ and CO₂ require a transport molecule in the blood, red blood cell hemoglobin, which binds the gases and allows them to be transported to and from the tissues.
