Answer:

Charles Robert Darwin was a British naturalist and biologist known for his theory of evolution and his understanding of the process of natural selection

Explanation:

2. Some of these variations are passed on to offspring;

As the genetic changes may occur due to mutations in the genes.
As these changes do not occur in days or months but they occur after hundred and thousands of years.
The off springs are distinct from their ancestors. This results in the formation of new species. Gradual modification of the existing species leading to the formation of new species is known as speciation.

4.Individuals vary in their ability to survive and reproduce;

Those with the most favorable adaptations are more likely to survive and reproduce.
Individual variation (usually through mutation) may introduce traits or abilities that enable that individual to survive in order to reproduce. Usually these are tiny incremental changes that accumulate over centuries or millennia.

Note: However there are certain drawbacks of Darwinism even such as it failed to explain the basis of variation and the mode of transmission of characters.

Explanation:

Transfer RNA is a type of RNA that help to translate messenger RNA sequence into protein. Each tRNA have two major areas; the anticodon and region for attaching specific Amino acids.

tRNAs function at specific sites in the ribosomes during mRNA deciding.

The four specific recognition sites of trna that must be inherent in it's tertiary structures in order for it to carry out it's role are;.

Interaction with ribosomes.

Interaction with aminoacyl tRNA synthase.

Attachment of specific Amino acid.

Interaction with codon.

Sexual reproduction produces genetically different offsprings which do possess variations, hence better chance to survive in the environment.

Option C

<h3>Explanation:</h3>

Sexual reproduction is the process of reproduction where there's a fusion of gametes from a male and female of the same species, resulting in a zygote and eventually an offspring. Sexual reproduction is very advanced type of reproduction which is very expensive for an organism. Much of the energy of the organism is spent to produce gametes and other necessary processes for reproduction.

Gametes of the sexual reproduction is produced mainly by means of meiotic cell division. This involves crossing over and chaismata formation which helps in genetic variations in the offspring. These variations help the species to survive unknown changes in environment, and helps to adapt quickly lessening the chances of extinction. So sexual reproduction has modified various times in different groups of species.
