Similarities in organisms with different genotypes indicates
1 microevolution
2 macroevolution
3 convergent evolution
4 divergent evolution
Explanation:
Convergent evolution refers to the evolution in different lineage of structures that are similar or analogous but that cannot be attributed to the existence of common ancestor. In other words the fact that the structures are analogous does not reflect homology. A similarity may reside at the phenotypic level, in which case the lineage share the over trait, but the underlying DNA sequences are different.

The unit of evolution is now known to be the
1 individual
2 family
3 population
4 species
Explanation:
The unit of evolution is now known to be the population. Evolution is defined as the changes acquiring in the inherited traits of the population from one generation to another. While population is the group of individuals who are of the same species living in the same geographical area and also interbreed with each other. The smallest and fundamental unit of evolution is the population that undergoes any type of evolutionary change.

The concept of chemical evolution is based on
1 crystallization of chemicals
2 interaction of water, air and clay under intense heat
3 effect of solar radiation on chemicals
4 possible origin of life by combination of chemicals under suitable environmental conditions
Explanation:
The theory of chemical evolution was proposed by Oparin and Haldane in 1992**. Chemical evolution suggests that under the right conditions on early Earth, various organic molecules and compounds could have formed through a series of chemical reactions. These are organic molecules, such as amino acids and nucleotides.

There is no life on moon due to the absence of
1 \(\mathrm{O}_{2}\)
2 Water
3 Light
4 Temperature
Explanation:
BThe absence of water is a significant factor in the lack of life on the Moon. Water is a fundamental requirement for life as we know it, and the Moon's harsh environment, including extreme temperature and vacuum, makes it hospitable for life as we find on earth.

Earth originated approximately:
1 4,500 million years ago
2 3,600 million years ago
3 between 1,600-2,600 million years ago
4 2.5 million years ago
Explanation:
Earth formed around 4,500 million years ago, approximately one-third the age of the universe. It is believed to have been born \(4-5\) billion years ago as a solidified cloud of dust and gases left over from the creation of the sun.
