The continental drift affects living organisms in that it causes changes in climates which puts selective pressure on organisms, causes changes in habitats, including when large amounts of shallow marine habitat were lost in the formation of Pangea. Additionally continental drift may cause an increase or decrease in competition among different species and also it happens so slowly that it does not affect living organisms
Cortisol hormones are stress hormones that increase blood glucose levels. When the level of happiness increases the level of cortisol does not increase.
<h3>What are cortisol and its function?</h3>
Cortisol is the steroidal hormone that is produced in the cortex of the adrenal glands and is discharged in the blood vessels when in stress or danger.

<u>Answer</u>: A heritable trait can be changed from one generation to another.
<u>Explanation</u>:
- The concept of <em>descent with modification</em> was given by Darwin which simply states that the traits are passed on from the parents to the offsprings.
- The traits that can be passed on are known as <em>heritable traits</em>.
- These traits are passed on with the help of the genes.
- So this passing on of traits explains the term <em>descent</em> in this concept. However, there are always chances that these heritable traits can be changed due to environmental factors or due to the process of recombination and thus the term <em>modification</em>.
- So <em>descent with modification</em> means that a<em> heritable trait is passed from parents to offspring but it can be changed from one generation to another.</em>
