Answer:
Hormones can be proteins, lipids or cholesterol-based molecules. Neurotransmitters are protein. The main difference between hormones and neurotransmitters is that Hormones are produced in the endocrine glands and released into the bloodstream where they find their movement targets at a distance from their origin. In contrast, Neurotransmitters are released into the synaptic space by a terminal of an excited presynaptic nerve cell and transmit a nerve signal to the neighboring postsynaptic nerve cell.
Explanation:
The force between them if the distance between them is doubled is a. F/4
Explanation:
- To find the answer, we can use Coulomb's law where it is defined as the force between two point charges is directly proportional to the magnitude of the point charges and proportional inversely to the distance between them.
- The equation can be written as,
where k is the Coulomb constant, 
are the point charges, and r is the distance between these two point charges. - To find the answer to this question, just substitute 2r in the place of r hence, you will get
as the new force when the distance is doubled.
Answer:
A plant cell
Explanation:
In the given question, a stage of a cell has been described during cell division.
The characteristic of this cell division are:
1. Nuclei are formed at opposite poles- shows that it is the stage of cell division
2. The formation of cell plate- the cell plate is formed in the middle of the cell which indicates that the cell is a plant cell.This cell is a plant cell as the cell plate is formed only in the plant cells and not in the animal cell in which the contractile rings are formed.
Thus, A plant cell is correct.
Grana is the term that describes stacks of thylakoids.
