While norepinephrine is majorly a neurotransmitter (in synaptic transmission)
, it also acts as a hormone produced by
the adrenal gland. It is usually secreted as a stress hormone, just like
cortisol. It increases heart rate, blood flow
in skeletal muscles, production of glucose by the liver, especially in the
fight-or-flight response.
The hypothesis which most likely explains the results is The enzyme breaks down at temperatures above 60°C; option B.
<h3>What are enzymes?</h3>
Enzymes are biological catalysts which speed up the rate of chemical reactions that occur in the body.
Enzyme activity is affected by the following factors:
- temperature
- pH of the medium
The temperature at which enzyme works best is known as optimum temperature.
The pH at which enzyme works best is known as optimum pH.
Considering the results of the experiment as shown in the graph:
The activity of the enzyme decreases to zero at 60°C.
Therefore, the hypothesis which most likely explains the results is The enzyme breaks down at temperatures above 60°C; option B.
In conclusion, enzymes are denatured by high temperatures.

Answer:
An organism that develops a trait that helps it survive in its environment will have a better chance of reproducing and passing that trait on to the next generation. As a consequence, organisms with this helpful trait will become more prominent while other organisms of the same species die out.

The meninges are the connective tissue coverings of the brain and spinal cord.
Answer: Lumbar and sacral nerves travel nearly vertically down the spinal canal to reach their exiting foramen. The spinal cord ends at the intervertebral disc between the first and second lumbar vertebrae as a tapered structure called the conus medullaris, consisting of sacral spinal cord segments.
