Answer:
Option-A
Explanation:
A bacteria divides by binary fission which divides a parent bacteria into the two daughter cells and generation time refers to the average time difference between two consecutive generations.
The bacterial cell grows by the exponential function that is by
x initial population of bacteria.
In the given question,
<u>Initial population</u>
the initial population of bacteria - 2x 10³ per ml
So per liter, the bacterial population will be 2 x 10 ⁶
<u>Generation time</u>
1 generation time of bacteria is 30 min.
so 5 hours will have- <u> </u>
= 10 generations
<u>New bacterial population</u>
Using formula<u> </u>
x initial population of bacteria
x (2 x 10⁶)
= 1048 x (2 x 10⁶)
2048 x 10⁶
Thus, Option-A is the correct answer.
Mrs. Lopez has the most difficulty initiating digestion of proteins after her stomach is removed. The correct option is C.
Explanation:
When the stomach is removed due to complications such as in cancers the food eaten directly goes to intestine. Without stomach Mrs Lopez will have difficulty in starting the digestion of protein.
The digestion of protein takes place and starts in the stomach and duodenum of intestine. There are enzymes as pepsin, trypsin and chyomtrypsin secreted by stomach and pancreas. Pepsin breaks the peptide bonds of protein.
The HCl and the enzymes in stomach initiates the process of digestion of protein. The amino acids formed are ardent in various metabolic processes and repair.
lipids and carbohydrate digestion starts from the mouth only as salivary amylase and lipase initiates the process.
The Noble Gases. The Noble Gases is a(n) group on the periodic table of elements that contains elements that have full valence electron shells. Because of this, the Noble Gases do not react with any other elements.
Answer:
B. Disruptive Selection
Explanation:
the population is divided into two distinct groups, or is disrupted so the gentics start to vary between the separted populations over time.
)Sexual reproduction maintains a constant level of variation in the population and requires less energy.
