Answer:
Explanation:
A gene can be turned on or off by environmental factors or from other cells that activate proteins known as transcription factors.
14: Operons allow prokaryotes to replicate DNA at the appropriate time.
Operons are specific regions of genes that are linked to a singular process. They ensure that the expression of these genes does not go unchecked and only occurs when necessary. Two key examples of this in humans are the lac operon and trp operon.
15. The central dogma of molecular biology is:
DNA to RNA to Proteins
Protein Synthesis occurs in 3 steps.
First our DNA is translated into RNA. Next the RNA is sequenced into Amino Acids by reading the corresponding 3-Base Codons. These Amino Acid sequences form various protein structures.
Answer:
B.
Explanation:
Same but different because lizards are very similar to snakes. Snake are just more vicious.
You could do regular daisies, or pet grass... It could be almost anything.

The correct answer is option C, For more kingdoms were introduced
Linnaeus was the first to develop a system of classification of living things. He mainly grouped the living things into animal or plant kingdom, but later with the advent of microscope it became easy for the researchers to observe microscopic beings and thus three new kingdoms were proposed namely- fungi, protists (considered as simple organism) and monera (bacteria).
Not only this with in a kingdoms comes several phylum, these phylums were also reorganized and recategorised based on the discovery of more categories and subcategories.
