Answer:
It depends whether you're talking about catabolism or anabolism. If you're creating new organic compounds, then it's an anabolic reaction. That way, ATP will be broken down, so as to fuel the chemical reactions. However, if you are talking about catabolic reactions, in which you aim to obtain ATP, by means of degradation of certain substances, in that case the right answer would be II.

There are at least three primary functions that are performed by the epithelial tissue.Firstly it provides a great protective covering for all the tissues lying beneath it from radiation, toxins, physical trauma, desiccation and invasion of pathogens. Secondly it helps to regulate the exchange of chemicals between the body cavity and the tissues that lie underneath the epithelial tissues. It also helps in the secretion of the hormones in to the bloods. These are all major but primary functions of the epithelial tissues. From this we can easily understand the importance of the epithelial tissues.</span>
Answer:
A neuron's nucleus is located in its CELL BODY
A nerve impulse moves toward a neuron's cell body along AXON
Explanation:
A neuron consists of three major parts: cell body, dendrite and the axon.
1) The cell body consists of the nucleus and cytoplasm
2) Dendrites are short cytoplasmic filaments which conduct impulses towards the cell body
3) Axon is made up of a single, long fibre which transmits impulses away from the cell body
Answer:
a. Water will move out of the cell
b. Shrink
c. Hypertonic solution
Explanation:
a. The scenario given shows that there is greater concentration of solutes outside the cell than the concentration of solutes inside the cell because there is 75% water inside the cell and 60% water outside the cell. So by osmotic pressure, water moves out of the cell.
b. Once the cell loses water it would shrink
c. It is an hypertonic solution because the concentration of solutes outside the cell is greater than the concentration of solutes inside the cell.
