How many fatty acids are in a phospholipid? request answer part b what functional feature(s) does the phosphate group contribute to the structure of a phospholipid? select all that apply. select all that apply. nonpolar group that avoids water place where bonds can form between adjoining phospholipids place to attach fatty acids negative charge to interact with water place to attach another small charged molecule?

1. Answer;

-Two fatty acids

Explanation;

-Phospholipids have a hydrophilic head and a hydrophobic tail.

-The hydrophilic head includes a glycerol molecule attached to a single phosphate group, which is then attached to another small molecule. The phosphate group and its attachments are either polar or charged. Water molecules are polar and therefore are attracted to these charged regions of the phospholipid head.

-The hydrophobic tails are two fatty acids attached to the glycerol molecule of the head. Water molecules are not attracted to the tails because C-H bonds are relatively nonpolar and therefore do not result in charged regions in the tails.

2. Answer;

-negative charge to interact with water

-place to attach another small charged molecule

Explanation;

-Phospholipids vary in the small molecules attached to the phosphate group.

-Because the phosphate group and its attachments are either charged or polar, the phospholipid head is hydrophilic, which means it has an affinity for water.A phospholipid also has two "tails" made up of two fatty acid molecules, which consist of a carboxyl group with a long hydrocarbon chain attached.

answers: to make sure that all of the broken pieces of tablet were added to the water, to allow for fair comparison of all three trials, with different particle sizes to avoid experimental error

a electronegativity decreases beacuse the size of nucleus is bigger.
