These two elements are transposase and terminal repeats. Transposase enzyme binds to the end of a transposon and catalyzes the movement of the transposon to another part of the genome by a cut and paste mechanism or replicative transposition mechanism. Terminal repeats are identical sequences which repeats hundreds or thousands of times, found at the end of proviral DNA formed by reverse transcription of retroviral RNA. They are used by viruses to insert genetic material into the host genomes.
<h3>1.<u> Answer;</u></h3>
A. lipid
<h3><u>Explanation;</u></h3>
- <u><em>Lipids are among the four biomolecules, others being nucleic acids, carbohydrates, and proteins.</em></u>
- <u><em>Lipids contain hydrocarbons and make up the building blocks of structure and function in living cells. Lipids includes; fats, oils, waxes and certain vitamins.</em></u>
- <u><em>Lipid can be used for energy storage in the form of fat in animals. Additionally, lipids can be used as heat insulation as fat or adipose tissue under the skin reduces heat loss.</em></u>
<h3>2. <u>Answer;</u></h3>
B. The cell membrane contains cholesterol molecules.
<h3><u>Explanation;</u></h3>
- <em><u>The structure of the lipid bi-layer allows small, uncharged substances such as oxygen and carbon dioxide, and hydrophobic molecules such as lipids, to pass through the cell membrane, down their concentration gradient, by simple diffusion.</u></em>
- <u><em>Carbon dioxide and oxygen are molecules that can move across the lipid bi-layer without the help from membrane proteins or integral proteins. They are non-polar molecules and thus can easily pass through the hydrophobic interior of a membrane.</em></u>
Answer:
When the battery is used to start the car, The energy is converted from electrical to mechanical energy to move the car, The chemical energy in the form of gasoline converts to the mechanical energy, and each transformation leads to the production of the heat.
Answer:
hom0zygous recessive
Explanation:
Hom0zygous is the term for the lettering of a recessive trait ( two lowercase letters)
I believe the correct word in the blank would be biological. I don't think anything else will fit in, especially when monomers of biological polymers are truly larger and more complex.
