Answer:
Option A, B, C, D and E
Explanation:
The first option indicates an early retroviral colonization of large double-stranded DNA viruses, which are the presumed ancestors of the eukaryotic nucleus; and then inappropriate activation of the telomerase can be implicated in the development of cancer by continous elongation of the telomere length without control.
Its activity can also be turned off leading to continuous shortening during replication and bringing about senesence and aging. the T-loops formed by the activity of the telomerase protects the ends of the chromosomes from being recognized as being broken and degradation.
Answer:
B. taking a shorter shower
Explanation:
Using the same bag would be reusing
Taking a shorter shower reduces the amount of water you use.
Turning old cans into new ones is recycling.
Throwing your trash in the garbage is wasteful.
The pharynx would need to come first in order for C to be correct.
B is also incorrect. Air flows through the bronchioles, then the
alveoli, and finally into or out of the capillaries where gas exchange
can occur with cells.
A is the only option that correctly describes the path of air through the respiratory system in the correct sequence.
The complete flow of air would be:
Nose>pharynx>trachea>bronchi>bronchioles>alveoli>gas
exchange with cells and then back out.
The correct answer choice is answer B.) The fossil record provides evidence of a common ancestor to many species. Hope this helped!
