Answer:
The correct option is A. His research was not appreciated by the scientific community until after he died.
Explanation:
Gregor Mendel was an Austrian monk who laid the foundation of genetics. Mendel studies seven traits from the pea plants and formed the law of segregation and law of independent assortment.
The work of Mendel was not appreciated until his death. In the 20th century, his work was eventually rediscovered and appreciated.
However, Mendel's study did not include any explanations for polygenic traits. His results could predict heritability in both plants and animals.
Proteins serve as antibodies.
B. It is a form of passive transport.
Explanation:
Tropical rain forests are one of the densely vegetated forests with millions of plants and animals species. The climate of the Earth is changing at an alarming rate and the scientists are appealing people to save these forests.
This could be accounted for the reason that the tropical forests have a diversity of plant species which can utilize the available carbon dioxide from the atmosphere to perform photosynthesis. This can directly reduce the carbon dioxide concentration in the atmosphere which is responsible for the greenhouse effect.
The greenhouse effect increases the temperature of the Earth as the greenhouse gases like carbon dioxide and monoxide covers the atmosphere which does not allow the sun rays to deflect back from the surface of the earth and the heat energy is trapped in the atmosphere. This heat energy is one of the causes of Global warming.
