They are thought to have separate paths of evolutionary development.
They developed along different evolutionary paths.
They had independent evolutionary development.
The answer would be A packing becomes less tight. The double bounds create kinks in the chain making it harder for the chains to back tightly
Answer:
b) Tendon
Explanation:
Tendons are fibrous, thick, stiff and flexible structures, with a whitish color, present in different parts of the human body.
They are part of the striated muscle being made up of connective tissue (composed of collagen).
The main function of the tendons is to connect the muscles to the bones. In this way, it helps in the balance of the body and in the development of movements, distributing the forces in the muscles.
As it pulls the connecting bone with the muscle, the tendon creates the movement in order to transmit the force of the contraction to the bone.
In addition, the tendon provides stability to the joints (meeting point between two bones) of the body's joints.
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!
The answer is true.
All of them bunched together is called a community
