Answer:

Passive transport.

Explanation:

Osmosis and diffusion because a single substance tends to move from an area of high concentration to an area of low concentration until the concentration is equal across the space. Osmosis is a passive transport process during which water moves from areas where solutes are less concentrated to areas where they are more concentrated.

The optimal window for post-exercise recovery to replenish nutrients lost during training begins __________.
Andru [333]
I believe the answer is within 30 minutes after exercise. 
There are two optimal windows of recovery following a hard workout that play crucial roles in helping the body recover as quickly as possible. The first window of recovery begins within 30 minutes following prolonged exercise. The second window for optimal recovery is from one hour to three hours post workout.

GTPases serve in many signal transduction pathways and the presence of GTP or GDP dictates where the pathway is on or off, respe
Anton [14]

Answer:

None of the above.

Explanation:

GTPases are the regulatory proteins that are involved in the signal transduction pathway involving the activation of the G protein. The mutation in these proteins cal lead to cancer cells.

The guanine nucleotide exchange factors (GEF) allows the replacement of GDP by GTP. They activates the GTPase activity of the cell and can also activate the multiple GTPase activity of the cell. The Ras superfamily is activated by the GEF.

Thus, the correct answer is option (d).

A disease was caused by a bacterium; you want to produce a biological product to kill this bacterium. Which product you have to
makvit [3.9K]

Answer:

The product that must be produced to kill a bacterium —which causes a disease— is an antibiotic, which through biotechnology can investigate the structure of the bacterium and synthesize the chemical formula needed to produce antibiotics in high amounts.

Explanation:

Antibiotics are specific medicines for the treatment of infectious diseases, produced by bacteria. <u>Antibiotics can kill bacteria and prevent their replication</u>.

If a disease is produced by bacteria, the product that is necessary to kill those microbes is an antibiotic, for which biotechnology is useful.

By using biotechnology —a branch of biology that uses technology as a research and development tool— it is possible:

  • <em>Know the structure, functions and behavior of pathogenic bacterial strains. </em>
  • <em>Create chemical formulas -antibiotics- that serve to effectively eliminate bacteria, and cure infectious diseases. </em>
  • <em>The synthesis and production of antibiotics on a large scale, allowing their sufficient availability for use.</em>
