Answer:
<em>Avoidance Learning</em>
Explanation:
<em>Avoidance learning</em>, also known as <em>escape learning</em>, is the procedure whereby a person learns how to conduct himself or react <em>to prevent a stressful or uncomfortable circumstance.</em>
The conduct is to prevent the scenario, or to get rid of it. It is a form of <em>absence of punishment</em>.
Answer: All membrane lipids are amphipathic
Explanation:
The membrane lipid molecules are amphathic in nature which states that they are both hydrophobic and hydrophillic part. The lipid bi layer has been found tot be the most widely found in cell structure.
The structure is made of phosphorus and lipids and hence called as phospholipids.
The amphipathic nature of the lipids allows it to assemble spontaneously into bi layers even under the artificial conditions.
hence, all the lipids in the cell membrane or membranes are amphipathic in nature.
This is evidenced by Doppler
shift effect. This is the phenomenon where waves that are coming from an object
that is accelerating towards your direction are heard at a higher frequency than that of
objects moving away from you. This is the same for light (which also has
wave-like properties). When observing distant galaxies, astronomers discovered that
they all showed to be redshift (change in the frequency of light towards red
color). This means that all galaxies are moving away from each other because
the universe is expanding.
Scientists will probably look at the birds' beaks, feathers, skeletal structure to see if they are closely related.
