Answer:
All living organisms are classified into groups based on very basic, shared characteristics. The classification of living things includes 7 levels: kingdom, phylum, classes, order, families, genus, and species . Kingdoms. The most basic classification of living things is kingdoms.
The genetic change causes alterations in only one or a few nucleotide bases in known as mutation.
A mutation is a change in a brief section of a genome's nucleotide sequence. Another frequently replaces one nucleotide in point mutations; other changes involve the insertion or deletion of one or more nucleotides.
Errors in DNA replication or the harmful effects of mutagens, such as chemicals and radiation, which react with DNA and alter the architecture of individual nucleotides, are the leading causes of mutations.
DNA repair enzymes are present in all cells and work to reduce the frequency of mutations. These enzymes reduce genetic information loss, double-strand break formation, and DNA crosslinking by repairing DNA damage.

The hormone ethylene is a gas and disperses easily.
Answer:
C. Guard cells and storage parenchyma cells each make a different set of proteins, which determines each cell type's structure and function.
Explanation
Both of these are two types of specialized cells that make specific combinations of proteins, which allows them to have unique structures and functions.
In DIFFUSION AND FACILITATED DIFFUSION no energy is used. The one that needs a helper to get thing across is FACILITATED DIFFUSION.<span> Facilitated diffusion involves the diffusion of materials across the cell plasma membrane with the aid of membrane proteins such as carriers and channels. The process of diffusion does not need a carrier, the molecules to be transported just move on their own from the area of high concentration to the region of low concentration until the concentration in the space become uniform.</span>
