Answer: Nitrogen is so vital because it is a major component of chlorophyll, the compound by which plants use sunlight energy to produce sugars from water and carbon dioxide (i.e., photosynthesis). It is also a major component of amino acids, the building blocks of proteins.
Explanation:
Answer: Genetic equilibrium is a situation where allele frequencies in a gene pool are not changing. In other words, the population is not evolving. The conditions to maintain the genetic equilibrium are no mutation, no gene flow, large population size, random mating, and no natural selection. The equilibrium can be disrupted by deviations from any of its five main underlying conditions.
An example of this in humans would be a heterozygote for brown eye color. The person would carry both a dominant brown allele “A” and a recessive blue allele “a” yet have brown eyes. The dominant brown allele masks the recessive blue allele. Genetic equilibrium is the state in which allele frequencies remain constant.
Answer:
Plant cells have a cell wall, but animals cells do not.
Plant cells have chloroplasts, but animal cells do not.
Plant cells usually have one or more large vacuole(s), while animal cells have smaller vacuoles, if any are present.
Explanation:
The answer is C, the opposite
