Answer:
Option C, open chemically gated sodium ion channels.
Explanation:
The nicotinic receptors are present on the muscle cell membrane. These receptors belong to the class of cholinergic receptor which binds to the acetylcholine and opens the gated channel to allow transfusion of cation through it. These actions of the receptors are stimulated by the neurotransmitter. Nicotinic receptors are very fast at acting and hence are more prevalent at the neuromuscular junction.
Hence, option C is correct
The meaning of the term photosynthesis is the process by which green plants manufacture their food (sugar) through the use of inorganic substances and sunlight as a source of energy.
Before photosynthesis takes place in a green plant, there must be presence of inorganic substances such as:
- water
- carbondioxide and
- sunlight (energy source).
The energy from sunlight is captured by the pigment called chlorophyll which is present only in green plants.
The products of photosynthesis is simple sugars with the giving off of oxygen as a by-product.
Therefore, photosynthesis is the process by which green plants manufacture their food (sugar) through the use of inorganic substances and sunlight as a source of energy.

The answer is B Adipose tissue.
We know that it cant be C or D
And A was wrong.
One wouldn’t allow for passive transport. And the other would allow to much. The membrane serves as a gate. Non-permeable would be a solid wall were nothing and no one can get through or get out . Including things like water. And fully permeable would represent no gate at all and would allow to much in and out of the cell.
I believe it is its reproduction rate
