B, of course! DNA is often referred to the ‘genetic code’ of the body and do regulate the production of genes.
Answer:
The study of the field of genetic engineering started with the emergence of cloning.
Explanation:
Genetic Engineering is the process of manipulation in an organism's DNA using tools of Biotechnology. Genetic Engineering started with the discovery of gene cloning. Gene cloning demonstrated that beneficial genes from one organism can be expressed into another host organism. For example, The human insulin gene was inserted into bacteria to produce insulin for human at large scale.
Enzyme may work if in it's optimum pH if the pH didn't match with the enzyme's pH, the enzyme will break down.
Enzyme will break down if the temperature so high it's called denaturation.
Answer:
a) produced the oxygen in the atmosphere
Explanation:
- Prokaryotes are likely to first form of life on earth and they existed billions of years ago before animals and plants.
- As these prokaryotes can do photosynthesis so there most important function is produce oxygen in atmosphere for the evolution of aerobic life.
- At that time the conditions were harsh on earth so these prokaryotes are used to survive under earth like in oceans. They first produce oxygen in oceans.
- In eukaryotes photosynthesis emerge by endosymbiosis with photosynthetic prokaryotes.
to keep them fresh and hydrated because even though there picked its helps keep them from drying out it also may clean any chemical or bacteria that would be leftover
