Answer:
Here, we have a composition passage and we are required to fill in the with missing words. The missing words are highlighted in bold format and underlined.
Lecithins and cephalins are both <u>glycerophospholipids;</u> they consist of <u>glycerol</u> with fatty acids forming <u>ester</u> bonds with the first and second <u>hydroxyl </u>groups. The third <u>hydroxyl</u> group of the <u>glycerol </u>forms a<u> phosphate bond </u>with phosphoric acid, which forms another<u> phosphate </u>bond with an amino alcohol. In lecithins, the amino alcohol is <u>choline;</u> in cephalins, the amino alcohol is usually <u>ethanolamine. </u>
Explanation:
Lecithin is a chemical complex composed primarily of fatty acids, glycerol, phosphoric acid, and choline. It can be present in egg yolks, soybeans, sunflower seeds, and plant seed cells and is completely normal. Soybean and sunflower lecithins contain much more important fatty acids than rapeseed lecithin, making them nutritionally more useful.
Phosphatidylethanolamine, also known as cephalin, is a phosphoglyceride that, like phosphatidylcholines and lecithins, is a component of biological membranes. A glycerol residue esterified by two fatty acids and a phosphoethanolamine residue gives rise to phosphatidylethanolamines. They're made by combining CDP-ethanolamine with diglycerides and releasing a CMP molecule. Phosphatidylcholines are formed when S-adenosylmethionine methylates the amine in ethanolamines. They're mostly found in the inner layer of plasma membranes' lipid bilayers.

3/4 as you do the grid and f is for non dominant , F is for dominant and the F is in 3/4 of the boxes , therefore it is 3/4 chances
Answer:
One of the most critical interactions in an ecosystem between the biotic and abiotic environment is photosynthesis, the base chemical reaction that drives most life on earth. Plants and algae use sunlight, water and carbon dioxide to create the energy they need to grow and live via photosynthesis.
