Answer:
1.Phospholipids provide barriers in cellular membranes to protect the cell, and they make barriers for the organelles within those cells. Phospholipids work to provide pathways for various substances across membranes.
2.Carbohydrates are organic compounds that are organized as ring structures and are always composed of the elements carbon, hydrogen, and oxygen. Carbohydrates are truly hydrates of carbon because the ratio of hydrogen atoms to oxygen atoms is always nearly 2:1, as in H2O.
Explanation:
Mercury and Venus.
The order of the planets is
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, (and I guess based on your beliefs) and Pluto.
The question is incomplete as it does not have the options which are:
- greater the unsaturation, the lower the fluidity.
- greater the unsaturation, the higher the melting temperature.
- lower the unsaturation, the greater the fluidity.
- greater the unsaturation, the greater the fluidity.
- Canadians have developed plants with higher amounts of unsaturated fatty acids.
Answer:
Greater the unsaturation, the lower the fluidity.
Explanation:
The differences in the lipid content of the membrane of the plant cells in Canada and Africa can be accounted for the difference in the temperature of Canada and Africa.
The temperature in Africa is higher compared to Canada as a result of which the cell membrane increase saturated lipids which could keep the membrane normal whereas the Canada plants increase the unsaturated lipids which increase the fluidity of the membrane.
Thus, the selected option is correct.
