The cell membrane folds upon itself easily, which facilitates cellular reproduction by mitosis. 

<span>The membrane is a flexible, fluid mosaic and changes shape easily to create holes for substances to move in and out of the cell. </span>

<span>The outer layer of the membrane is hydrophilic, which allows water to flow in and out of the cell easily to eliminate waste. </span>

<span>The proteins that are embedded in the cell membrane act as channels to transport substances in and out of the cell.</span>

Nucleic acid such as DNA is the repository of genetic information in most organism.

          The genetic information stored in DNA is Transferred to RNA by transcription which deals with the the production of mRNA from DNA.

        The mRNA then undergo translation to transfer its own own genetic information in form of codons to specify amino acids of a protein molecule.

        Thus the Central dogma of molecular biology relates proteins and nucleic acids.

Reika [66]

Answer:

Explanation:

The rate of pollination in the field (near the pond with no fish) will decrease exponentially. Because, as the fish population is removed from that ecosystem, the population of dragonflies and larva increases without check because, fish feeds on the dragonflies larva and kept there population in check. Due to this, the population of bees and other pollinators population decline becuase, they are major food source of dragonflies.

Honeybees are the keystone species because it's absence will lead to major changes in the ecosystem.
