Answer:

<u>Proto-oncogenes</u>

  • These genes code for protein that normally promote cell division
  • Mutations that increase activity of these genes may lead to cancer

<u>Tumor suppressor genes</u>

  • These genes code for protein that normally prevent uncontrolled cell division
  • Some products of these genes normally function in repairing damaged DNA
  • Mutation that decrease activity of these genes may lead to cancer.

Explanation:

<em>Proto-oncogenes</em> are group of genes that ordinarily help cells develop. At the point when a proto-oncogene mutates or there are such a large number of duplicates of it, it turns into a "terrible" quality that can turn out to be forever turned on or activated when it shouldn't be. At the point when this occurs, the cell becomes wild, which can prompt malignant growth. This terrible quality is called an oncogene.

Tumor suppressor genes are normal gene that hinder cell division, fix DNA missteps, or tell cell when to undergo apoptosis (die). At the point when tumor suppressor gene don't work appropriately or inactivated, cells can develop uncontrollable growth, that ultimately lead to cancer.

What happens to a cell to specialize as a red blood cell
OverLord2011 [107]

Answer:

Red blood cells transport oxygen around the body. They are specialised to carry oxygen because they: contain large quantities of a protein called haemoglobin , which can bind oxygen. don't have a nucleus, so there is more room for haemoglobin.

The somatic motor division consists of somatic motor neurons that innervate cardiac, smooth, and skeletal muscle cells. The soma
juin [17]

Answer: FALSE

Explanation:

The nervous system is the system that detects and responds to changes inside and outside the body. This system consists of the brain, the spinal cord and peripheral nerves. The structure and organisation of the tissues that form these components enables rapid communication between different parts of the body.

Parts of the nervous system includes:

--> Central Nervous System ( consists of the brain and spinal cord)

--> Peripheral Nervous System ( consists of nerves outside the brain and spinal cord).The two functional parts of the peripheral nervous system are made up of the sensory (afferent) and motor (efferent). The motor division is involved in activities that are voluntary (somatic nervous system) and involuntary (autonomic nervous system).

The somatic motor division consists of somatic motor neurons that innervates ONLY the SKELETAL MUSCLE for its voluntary actions while the autonomic motor neurons innervates the cardiac and smooth muscles. Therefore the statement is FALSE

What is the cause and effect between mutations and effects of gene expression?
Leto [7]
The cause of mutations in gene expressions are the changes of gene instructions that causes your protein to malfunction. The effect of mutations are the genes not being able to function properly and send the wrong codes/info to your cells.

Many naturally occurring environmental exposures increase risk for cancer. Residents in many parts of North America are exposed
Katena32 [7]

Answer:

RADON GAS

Explanation:

Radon is a naturally occurring gas, which is produced due to the radioactive decay of the Radium element. It is one of the dense gas that is mostly concentrated in the lower portion of the houses, and are trapped in the cracks and fractures of the walls of houses and buildings.

Radon gas is an invisible, colorless and odorless gas, which is a very harmful gas, and exposure to Radon gas can cause an individual to suffer from cancer.

In recent studies, it has been found that in many parts of North America, a large number of residents are exposed to Radon gas, which led to an increased risk of cancer.
