<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:
The unique characteristic of earth is liquid water.
Explanation:
The correct answer is "they originate as pockets, rather than forming continuous tubes".
Lymphatic capillaries are very small vessels located between cells. Their function is to absorb and process extracellular fluid. They have very thin walls and larger diameter than blood capillaries. Another important characteristic is that they have closed ends, permitting the extracellular fluid to flow in but not out.
Answer:
it provides energy for conversion of ADP to ATP by ATP synthase. Anabolic pathways store energy by building molecules
Explanation:
Catabolic pathways release energy by breaking down molecules. ... Hydrogen ion generation is essential for ATP production because it provides energy for conversion of ADP to ATP by ATP synthase.
