Answer:
False
Explanation:
Gram stain technique is a method use to classify bacteria into large groups base on their different cell wall components. It differentiate gram positive and gram negative by coloring them with red or Violet colors.
Gram stain is use for identification and classification of bacteria.
Gram positive stain violet due to presence of thick layers of peptidoglylcan in their cell walls and gram negative stain red due to thin layers of peptidoglylcan in their cell walls.
<span>Sclerenchyma cells are the strongest. They have a second cell wallwhich is hardened by lignin, making them very tough and durable.</span>
There are several ways selection can affect population variation:
stabilizing selection
directional selection
diversifying selection
frequency-dependent selection
sexual selection
As natural selection influences the allele frequencies in a population, individuals can either become more or less genetically similar and the phenotypes displayed can become more similar or more disparate. In the end, natural selection cannot produce perfect organisms from scratch, it can only generate populations that are better adapted to survive and successfully reproduce in their environments through the aforementioned selections.

Answer:A=V
Explanation:
It is used to move small or non polar molecules does not apply to facilitated diffusion. Small, non-polar molecules can diffuse directly across the phospholipid bilayer.
I would personally go with D or B
