Answer:
True
Explanation:
Prokaryotic cell or bacterial cell contain cell wall which is made up of peptidoglycan and traditional antibacterial antibiotics were able to interfere with the cell wall synthesis and cause the destruction of bacterial cells.
For example, one of the most traditional antibiotic is penicillin which inhibit the synthesis of bacterial cell wall by blocking transpeptidation reaction. As it inhibits new cell wall formation it results in the formation of holes in the cell wall.
These holes in the cell allow movement molecules inside the cell and cause osmotic cell lysis. Therefore the statement is true.
It shows evolution and growth from the past and present
A habitat left unoccupied by native herons and egrets met the biotic and abiotic requirements of the cattle egret transplants and their descendants
Answer: Option B
<u>Explanation:</u>
The cattle egret was a species of Heron to be first seen in Greater Caribbean Basin. They acquired their name “Cattle egret” as they were found to be co-existing with the grazing cattle and feeding on the insects that come out during grazing and also feed on the ticks present on the cattle’s body.
The cattle egret within a span of few years showed a dramatic increase in its population. This was attributed by their high reproduction rate leading to their extensive population growth. They also do not have any predators devouring them. They also feed on anything and everything to survive be it insects, rodents or small reptiles. They were good flyers and they were also able to get accustomed to their surroundings and reproduce.
