1. Nucleic acids are the molecules that code the genetic information of organisms.
2. The two nucleic acids used in the repair, reproduction and protein synthesis are deoxyribonucleic acid (DNA, shown) and ribonucleic acid (RNA)
3. DNA and RNA are polymers made up of monomers called nucleotides
This is because plants has cell wall while dog doesnt have. <span>A </span>cell wall<span> is a structural layer surrounding some types of </span>cells<span>, situated outside the </span>cell<span> membrane. It can be tough, flexible, and sometimes rigid. It provides the </span>cell<span> with both structural support and protection, and also acts as a filtering mechanism.</span>
As a mechanism of evolution, natural selection can be most closely equated with UNEQUAL REPRODUCTIVE SUCCESS.
Mechanism of evolution refers to micro-evolution that involves mutation, gene flow and natural selection. Unequal reproductive success is also related to other processes of micro evolution such as natural selection. The organisms that can reproduce unequally and survive even in adverse condition, increase in numbers.
