Every fatty acids has a long hydrocarbon chain (with even amounts of carbons, usually 16 or 18) and a carboxyl group.
glycerol is a 3-carbon molecule with 3 -OH groups.
fatty accids and glycerol can be connected by single or double bonds, depending on if the fatty acid is saturated or unsaturated.
when a lipid forms, the -COOH functional groups of 3 fatty acids react with -OH groups of glycerol.
this leaves 16, 18, or 20 carbons, making a triglyceride 16, 18, or 20 carbons long.
hope this helps!
Answer:
In biology, the relationship in which one organism lives inside another is described by the term endosymbiosis.
Explanation:
Endosymbiosis refers to a form of association that organisms have, in which one individual lives and performs his functions within another's body -using his resources to survive- being called the first symbiont, and the second host.
An example of endosymbiosis is found in bacteria that are part of the intestine of some living organisms, contributing to the process of food degradation.
Additionally, endosymbiosis is relevant in explaining the origin of eukaryotic cells from symbiosis between prokaryotic cells, which is known as endosymbiotic theory.

Answer: 50% ErWw (wild-type traits) and 50% rrww (red eyes, white-banded wings)
To solve this, we need to analyze step by step all the data they give us.
First, they told you about two homozygous traits that are recessive in this kind of animal, Red eyes and withe-banded wings.
We'll assign the names rr and ww (lower because they are recessive)
You know the dominant traits are wild type and all are in the same chromosome.
EE will be normal eyes, and WW will be normal wings.
If you cross this F0, rrww x EERR all the offspring are ErWw.
Crossing F1 with red eyes, with-banded wing you have to draw a Punnte square with ErWw x rrww and the ofsspring posibilities you'll find are 50% ErWw (wild-type traits) and 50% rrww (red eyes, white-banded wings)
Answer:
The first statement
Explanation:
Osmosis is the transfer of water molecules from a low concentration to a higher concentration through a partially permeable membrane
The partially permeable membrane only allows water molecules to pass through
Therefore, the first statement best describes osmosis
