PLEASE SOMEONE HELP ME I’M REALLY STRUGGLING

Answers

Answer 1

Answer:seventy-seven thousand years ago, a craftsman sat in a cave in a limestone cliff overlooking the rocky coast of what is now the Indian Ocean. It was a beautiful spot, a workshop with a glorious natural picture window, cooled by a sea breeze in summer, warmed by a small fire in winter. The sandy cliff top above was covered with a white-flowering shrub that one distant day would be known as blombos and give this place the name Blombos Cave.

Which conclusion about the growth of new bacterial cells does the experiment support?
O Heat helps bacterial cells grow new bacterial cells faster.
New bacterial cells can only arise from preexisting bacterial cells.
The amount of available nutrients impacts the growth of new bacterial cells.
Growth of new bacterial cells depends only on the presence of nutrients.

Answers

Answer: New bacterial cells can only arise from preexisting bacterial cells.

Explanation:

Option A is wrong because when heat was applied, there was no new bacterial growth. Most likely because the heat killed the bacteria cells. Option C is also wrong as well the third trial had nutrients but no new bacteria cells grew.

Option D is wrong because in Trial 1, there were nutrients and yet no new cells were formed. This means that growth of new cells depends on more than nutrients alone.

This leaves option B as the correct answer which is proven by the lack of growth of new cells when there were no pre-existing ones in trial 3.

Hopetown is farther from the equator than kamina. Which location has colder air temperature and why

Answers

Answer:

Hopetown

Explanation:

The farther from the equator the colder the air temperature. This is because the equator is the point on planet Earth that receives the largest amount of solar energy, so the regions that are above this line are the warmest in the entire planet. The further away from the equator a region is established, the less solar energy it receives, which is why the poles are so cold. In this case, we can say that the Hopetown temperature is colder than the kamine temperature.

Explanation:

DNA is the unit of heredity and present in almost every living organism, it carries the genetic information and transfer from generation to generations. In this process of transfer of the genetic information, there are two processes transcription and translation helps to produce protein.

The ability to produce proteins with the help of DNA for the particular function as said in question which is HGH production. Correcting the abnormality of not able to produce HGH, to produce the normal protein with the help of putting human genes into Bacteria as DNA is universal genetic language.
