Answer:
Most scientists, including Darwin, thought each species was specially created by God in its present form and did not change over time.
Explanation:
Gram-positive microorganisms have a thicker layer of peptidoglycan which traps a greater amount of the gem violet included and upon de-colorizer discharges approximately caught stains.
Gram-positive cell dividers contain a thick peptidoglycan layer with teichoic acids. Gram-negative cell dividers contain a thin peptidoglycan layer that is encompassed by a thick plasma film. Gram-positive microorganisms will recolor purple in view of their thick peptidoglycan cell divider.
D, increase population of all species, because humans have not helped increase the population of ALL species. In fact, humans are at fault for the decline of some species.
This is an example of an Epigenetic effect.
Explanation:
It is the study of heritable changes in the expression of genes, that are not involved in the changes present in DNA sequence. It is regular and naturally occurred, sometimes factors are responsible like age, lifestyle and disease state.
At times it leads to more damaging effect that can cause cancer. So this is also related to various fatal disease. During adulthood epigenetic effect remains stable. It does not occur in mother womb, but during the lifespan. This epigenetic effect can be reversed.
Answer AND Explanation:
Exponential phase is the phase during which growth is rapid. The growth rate is proportional to the amount of material or number of cells of the organism already present. This rapid growth is due to:
- An increase in number of cells dividing following a geometric progression.
- Cells having adjusted to the new environment.
- Food and other factors are not limiting hence cells are not competing for resources.
- The rate of cell increase being higher than the rate of cell death.
