When it is said that mutation is the ultimate source of genetic variation it means that it creates several new combinations which is similar to meiosis and fertilization because <span> new alleles and genes appear. It is just about some common points.</span>
<h3><u>Answer;</u></h3>
D) Mutations lead to new genes, which may have an advantage over the old forms, causing the species to evolve.
<h3><u>Explanation;</u></h3>
- <em><u>Mutations are sudden, random changes that occur spontaneously in the genetic make up of an organism.</u></em> Mutation are caused by various factors which includes errors in meiosis, and other factors such as chemical mutagens.
- <em><u>Mutations may be beneficial and may play an important role in evolution as they are raw material of genetic variation</u></em>. <em><u>Mutations may lead to genetic variations in the genetic make up of an organism . Therefore mutations are important to mutation since they create new DNA sequences for a given gene and thus resulting to new alleles.</u></em>
The three characteristics used to classify prokaryotes are shape, how they move, and how they get energy. Prokaryotes are unicellular or single celled organisms that lacks a membrane-bound nucleus, mitochondria, or any other membrane-bound organelles. Prokaryotes includes both bacteria and archaea and are found almost every where.
<h2>Monocular cue - Motion parallax</h2>
Explanation:
- When only one eye is used to perceive depth it is known as Monocular Cues.
- The various types of cues are as follows: aerial perspective, relative size, interposition, linear perspective, motion parallax and texture gradient.
- By using such cues artists create more Realistic creation.
- Motion parallax is a depth cue which takes place from the movement of our body relative to surroundings.
- Motion parallax makes the object that are closer to you to appear to move faster.
- The objects that are further away to you to appear to move slower.
The correct answer is C. Virus.
Virus falls on the gray area which is between nonliving and living things.
Virus is referred to as the small infectious agent which replicates only inside the living cells. Virus can infect life forms plants and animals and microorganisms, for example, archaea and bacteria.
They live in form of independent particles which are referred to as virions. Some viruses can evolve from plasmids.
