Answer:
glycine, alanine, valine, leucone, isoleucine, proline, phenylalanine, methionine, and trytophan are all amino acids with hydrophobic side chains.
The best answer is (3).
Guard cells help regulate water loss by controlling the opening and closing of stomata which facilitates gas exchange and transpiration in plants.
Guard cells are able to control the opening and closing of stomata by changing shape. The guard cells take in potassium ions which causes water to diffuse into them by osmosis. The cells then swell and become bowed. When this happens, they bend way from each other thereby opening the stomata.
When they lose the potassium ions, water diffuses out by osmosis and the cells become flaccid and less bowed thus closing the stomata between them.
<span>True. Sphagnum is a genus of mosses that can retain large amounts of water within their cells, due to the presence of pores in cells that can rapidly absorb water through their pores. The acidic water and the lack of oxygen cause the Sphagnum to decompose slowly, producing the accumulation of dead tissue, which can form a mantle from 1 to 9 m deep.</span>
The characteristics of most unsaturated fatty acids found within a human cell are deprotonated carboxylic acid and cis double bonds.
- With the exception of steroids, fatty acids are carboxylic acids that provide the structural foundation of fats, oils, and all other types of lipids. More than 70 have been found in the natural world.
- They are typically unbranched, contain an even number of carbon atoms (often 12–20), and can be divided into groups based on the existence and quantity of carbon–carbon double bonds.
- As a result, saturated fatty acids don't have any carbon-to-carbon double bonds, while monounsaturated fatty acids have one, and polyunsaturated fatty acids have two or more.
