How can one species eventually change into something completely different over the course of millions of years?

1 answer:

3 0

One species eventually changes into something completely different over the course of millions of years. This can be described using the evolution theory. The evolutionary process of species shows how one population of a species changes over time to the point where that population is distinct and can no longer interbreed with the parent population. Hence one species is changed into another over o period of time. Speciation is an evolutionary process by which a new species comes into being.

This theory of evolution was proposed by Charles Darwin.

What is the process that occurs in the Vesicle? (Biology)

Mariulka [41]

Vesicles form naturally during the process of secretion(exocytosis), uptake (phagocytosis and endocytosis) and transport of materials within the cytoplasm. Alternatively, they may be prepared artificially, in which case they are called liposomes.

Where are the richest deposits of oil and natural gas most likely located?

Maurinko [17]

Answer:

<em>The correct option is C) Continental shelves</em>

Explanation:

The continental shelf can be described as a part of a continent which is submerged in shallow water. This shallow water is known as a shelf. Hence, the name continental shelves.

Rich deposits of oil and natural gas can be present in this part of the sea. The continental shelves are of extreme commercial significance and are a commercial site for exploitation. The continental shelves can be rich in metallic and non- metallic ores and hydrocarbon products.

natulia [17]

Options for the question are not given. They are as follows:

a. arg or lys

b. ala

c. thr

d. leu or ser

e. Only termination codons

Answer:

d. leu or ser

Explanation:

Four codons code for proline amino acid. These are CCT, CCC, CCA, and CCG. Hydroxylamine causes C to change into T or G to change into A.

If first position is changed in each codon:

CCT = TCT (UCU)

CCC = TCC (UCC)

CCA = TCA (UCA)

CCG = TCG (UCG)

These codons produce Serine amino acid.

If second position is changed in each codon:

CCT = CTT (CUU)

CCC = CTC (CUC)

CCA = CTA (CUA)

CCG = CTG (CUG)

These codons produce Leucine amino acid.

Hence, out of the given options, option d. leu or ser is correct.
