Answer:
<u><em>Genetic variation</em></u> occurs because beneficial traits exist in a collection of genes, and <u><em>gene flow</em></u> makes these traits more prevalent in populations.
Explanation:
In biology, genetic variation can be described as the different genotypes which occur in species of the same kind. This genetic variation allows those organisms to survive on Earth which are better adapted to survive to the environmental changes.
The organisms which are better adapted to live in an environment will reproduce and pass their traits to the offsprings. Over time, these traits will become more prevalent in a population.
The nucleotide sequence would have to have 900 nucleotides in order to code for a protein of 300 amino acids. When translating RNA into proteins, RNA is read 3 bases at a time. Each group of 3 bases is a codon, and each codon codes for an amino acid. When read, the proper amino acid is added to a growing chain of amino acids, which will be folded to become a protein.
Therefore, 300 amino acids * 3 nucleotides per amino acid = 900 nucleotides.
<h3><u>Answer;</u></h3>
mechanoreception
In the context of sensation and perception, the detection of pressure by sensory receptors is called <u>mechanoreception</u>.
<h3><u>Explanation</u>;</h3>
- Mechanoreception involves detection and response towards certain kinds of stimuli such as touch, sound, and changes in pressure or posture.
- Mechanoreceptors are type of sensory receptors found on the skin and on other organs that detect sensations of touch. They are called mechanoreceptors because they are designed to detect mechanical sensations or differences in pressure.
