<span>Norepinephrine uses the Second
Messenger System, which means, cells signal to each other what molecules have
been released that will trigger a physiological reaction. </span>
<span>
This phenomenon is activated after the ligand (ion or molecule) is bonded to its receptor
(protein molecule), creating a variation that causes a chain-reaction, that will
finally activate the Second Messenger. The latter will activate intercellular
molecules that will be able to control the cell’s activity. </span>
HI there!!!!!!
It would probably be the heart, brain or our muscles; they are constantly working !
Answer:
The organism will pass on the traits to their offspring. If the offspring also has an increased chance of survival it will have a higher chance of passing on the traits. Over a long period of time the entire population can inherit this trait.
Explanation:
According to the theory of natural selection organisms with beneficial traits are more likely to survive to the reproductive stage and pass on the beneficial gene to their offspring. <em>Natural selection selects beneficial traits.</em>
Answer:
It is the process where the plants use sunlight to gain their food.
Explanation:
Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.
Hope this helps!
<h3><u>Answer;</u></h3>
Compressions
Rarefactions
<h3><u>Explanations;</u></h3>
- A wave is a transmission of a disturbance from one point to another, and involve the transfer of energy from the source to another point.
- Waves may be classified as longitudinal waves or transverse wave depending on the vibration of particles relative to the wave motion or mechanical and electromagnetic waves based on the material medium of transmission.
- <em><u>Sound waves are examples of longitudinal waves that are mechanical waves since they require material medium for transmission. Longitudinal waves involves transmission of waves such that the vibration of particles is parallel to the wave motion , creating compressions and rarefactions.</u></em>
