<h3>
Answer:</h3>
The generation of local currents.
<h3>
Explanation:</h3>
An action potential at the axon hillock generates local currents that depolarize nearby sections of axon to threshold. This change in membrane potential causes voltage-gated Na+ channels to open in the adjacent axon segment. This generates/regenerates the action potential in the adjacent segment, causing the action potential to propagate away from the axon hillock.
The distance between 1 and 7 spans a sarcomere correspond the structure at B is covered by the perimysium.
<h3>What is the smallest contractile unit within skeletal muscle?</h3>
A sarcomere comprises the segment between two consecutive Z lines and is the contractile unit of the muscle fiber, as it is the smallest portion of the muscle fiber capable of contraction and distension.
In this case, the distance between points 1 and 7 has the smallest structure of a skeletal muscle and corresponds to figure B.

Answer:
The correct option is <u>B. Lipids</u>
Explanation:
Lipids can be described as molecules which dissolve in non-polar solvents and cannot dissolve in water. The biological function of a lipid molecule is to store energy as well as to structure the shape of cell membranes. Lipids are also used in a cell for signalling.
Lipids are made up of carbon, hydrogen and oxygen. Some lipids might have phosphorus in them like the phospholipids which make up the cell membrane.
Answer:
Producers give off AND take in carbon dioxide
Explanation:
They give off carbon dioxide from respiration so they return carbon dioxide to the atmosphere. They also use carbon dioxide to synthesize their food.
