Cells are called the building blocks of life because they are the basic unit for all living organisms, and must be present for life to exist. ... The tiny parts of each cell are called organelles, which means "little organs" in Latin. Each cell in the human body is a small and simple form of life.
Answer:
A. True
Explanation:
Apoptosis is a normal cellular process in which the cell inherently programs the death of a mutated or damaged cell without affecting the healthy condition of the other surrounding cells by proliferating.
Apoptosis is a system of checks and balances that the cell uses to prevent damaged or mutated cells from proceeding to the next phase in the cell cycle. This curbs or prevent the damaged cell from passing on the problem to its daughter cells. Hence, according to this question, it is TRUE.
The correct answer is: Even though the S strain had been heat-killed, it changed the R strain.
Griffith in his experiment used two strains of bacteria:
• The rough strain (R) which did not cause pneumonia, (nonvirulent)
• the smooth strain (S) which did caused pneumonia (virulent)
When Griffith heat-killed the S strain it did not caused mice to die.
But, when he gave both the heat-killed S strain and the R strain to mice, the mice developed pneumonia and died.
Griffith conclusion was that the R-strain bacteria took what he called a "transforming principle" from the heat-killed S bacteria which transformed the nonvirulent R strain.
I stated three answers.
<span>1. White blood cells inundates bacteria that might entered the wound.
2. White blood cells produce antibodies that attack pathogens that might entered the cut(s).
3. They fight infection.(For Sure)
Hope this helped :D</span>
