At individual level i believe the mechanism of bacteria survival is brought about by the ability of bacteria to survive in extreme conditions such as extreme heat, cold, dehydration, and large amounts of ultraviolet rays. At population level, bacteria can produce quickly and their population grows rapidly.
Question 1: the cell must grow in size so there is enough material for each new cell
Question 2: interphase
Question 3: false
Answer:
The box will move toward you with a force of 10N
Explanation:
If you and your friend are pushing the same box with the same amount of force, those two forces will balance each other out, and the box won't move. In the question, 20N will cancel each other out, and there will be 10N. Your friend is pushing the box with more force than you, so it will move toward you with the remaining force of 10N
If an event caused the population to diverge into two different species over a long period of time, then is likely that a natural disaster separated it.
<h3>What is speciation?</h3>
Speciation is the evolutionary process by which a population generates two different species in a given period of time.
- Speciation usually occurs as a consequence of geographic separation and further reproductive isolation.
In conclusion, if an event caused the population to diverge into two different species over a long period of time, then is likely that a natural disaster separated it.

Answer:
A geneticist has devised a strategy to study protein translocation into the endoplasmic reticulum (ER) in yeast cells. She is interested in two different signal sequences that are thought to operate via slightly different translocation mechanisms. Using genetic engineering, she has fused the first signal sequence to a protein whose cytosolic expression is absolutely necessary for cell survival in the selective medium, but is inactive when in the ER. In the same cell, she has also fused the second signal sequence to a toxic protein whose cytosolic expression leads to cell lysis but is harmless when in the ER. Whereas wild-type cells undergo lysis upon the expression of these fusion proteins, she has been able to identify viable mutants, each of which has a loss-of-function mutation in a gene encoding a protein involved in membrane translocation. The products of these genes are probably ...
Explanation:
Involved in the transport of proteins with the first signal sequence but not the second one.
