D. sexual selection
D. Mutations
<span>These are all component of evolution in the promotion of biodiversity. How an organism evolves due to mutation, selection and adaptation. </span>
<span>Biodiversity depends on a species' ability to reproduce itself. If a species cannot reproduce then it will die out. This depends on the climatic conditions of the region. If there is a natural disaster for example, it will affect a species' ability to reproduce. This reduces the number of diverse species on earth. Biodiversity is the recognised variety of different types of life found on the earth. It also measures the variety of number and variety of plants, animals and other organisms found in different ecosystems.<span> </span></span>
Assume that the average protein in E.coli consists of a chain of 400 amino acids. Now, a single amino acid present in the protein requires a codon to code for it. A codon consists of 3 nucleotides. This shows that a protein of length 400 amino acids will require, 400 codons to code for it, that is, 1200 (3 x 400) nucleotides are required. We know that the length of the E.coli genome on average is 5 x 
base pairs.
1200 nucleotides = 1 protein
5 x nucleotides = X no. of proteins
X = 
= 4167
The answer is 4167 proteins.
Phylogenesis is the evolutionary development of particular features of an organism as well as the diversification of organisms, which sets them apart from one another.
Highly conserved proteins are useful in constructing phylogenesis because proteins are made by genes. These genes contain the genetic material of the organism. If the genetic material is in good condition, it is easier to study and the relationship of the particular organism with others is easily studied.
The answer is <span>A. Dermal tissue, ground tissue, and vascular tissue respectively.
<em>
</em>1. <em>Epidermis is dermal tissue. </em>Dermal tissue covers the plant from the outside. It consists of epidermis and periderm. Epidermis is a single layer that covers young plants.
2. <em>Sclerenchyma is ground tissue.</em> Ground tissue has a variety of functions. It consists of sclerenchyma and parenchyma. The function of sclerenchima is support and strength of roots, stems, and leaves.
3. <em>Phloem is vascular tissue.</em> Vascular tissue has a role in transport of minerals, water, and organic compounds. It consists of phloem and xylem. Phloem transport organic compounds, such as carbohydrates, hormones, etc.
