Studying evolutionary relationship among organisms
Answer:
Let's find out if exhaled air contains carbon dioxide.
Take a glass and fill it up with some limewater. ... The limewater turns milky. This goes to show that the carbon dioxide present in the exhaled air turns the limewater chalky. The limewater turns from clear and colourless to chalky.

If no egg has been fertilized, estrogen and progesterone levels are low. As a result, the top layers of the endometrium are shed, and menstrual bleeding occurs.
Explanation:
Answer – C. If the seed shape did not have a clearly dominant form
In doing his research on inheritance, Mendel studied seven different traits in peas, namely – height, flower color, seed color, and seed shape. Actually in Mendel’s study, seed shape had a very clear dominant form; having a smooth seed was a dominant trait and having a wrinkled seed was a recessive trait. If this clear dominant form could not be established, then Mendel’s experiment would have ceased to progress. Option B is not the answer because rate of reproduction was not one of the features that Mendel studied in the research. Options A and D are not the answers because they were the actual findings of the study.
