On a sunny day mark can stay in the sun for 20 minutes before he gets sunburnt. He wants to sunbathe for 3 hours. What is the lowest level of sun protection that he should use : 5, 15, 20, 30, 50Also the question below

Answers

Answer 1

Answer: For the 1st question, 30. Not too high, not too low.
2nd one is Their bodies are used to it and it's the way they were made, so lets say a (NOT BEING RACIST!!!!) let's say a white person and a Latino, went out, the white would have a greater risk because their bodies aren't used to the sun more than the Latino!

Which organelles of a cell possess their own DNA?. A) Lysosomes and plasma membrane. B) Mitochondria and chloroplasts. C) The Golgi apparatus and ribosomes

Answers

Nucleus is the central organelle of the cell which encloses the DNA. Apart from the nucleus, there are few other organelles which have their own DNA.Mitochondria,power house of the cell has its own DNA.so the selected cell possess is mitochondria and chloroplasts.

Mitochondria and chloroplasts are organelles of a cell possess their own DNA. Thus, option (b) is correct.

In both plant and animal cells, mitochondria are membrane-bound organelles that are essential for producing the chemical energy required for the cell's metabolic processes.

On the other hand, chloroplasts, which are only present in plant cells, are in charge of photosynthesis. Both organelles are involved in protein synthesis and have their own genetic material.

As a result, the significance of the organelles of a cell possess their own DNA are the aforementioned. Therefore, option (b) is correct.

The options

A. Personal mortality

B. Inevitability

C. Purposefulness

D. Organicity

The CORRECT ANSWER IS A.

A. Personal mortality

Explanation:

Universality

It as to do with the fact that all living things must gradually or at some point die. It sees Death as an all-inclusive, inevitable, and unavoidable.

A. personal mortality✔✔✔

It is the concept that death applies to oneself, that not only do all living things die but each and every living thing will surely die.

B. Inevitability❌

It is the concept that all living things must one way or the other encounter death.

C. Purposefulness❌

It has to do with death and it's purpose.

D. Organicity❌

It is the probable etiology of the inadequacy of full eyelid closure at death.

If two eukaryotes participate in lateral gene transfer what will this do to the overall genetic variation of thespecies?
A) Nothing, the genetic variation will stay the same.
B) The genetic variation will decrease.
C) The genetic variation will increase.
D) This type of gene transfer is impossible in eukaryotes.

Answers

Lateral gene transfer, also known as horizontal gene transfer, increases genetic diversity and plays a big role in evolution of single celled organisms.

Answer:

The correct answer would be C) The genetic variation will increase.

Horizontal or lateral gene transfer refers to the transmission of genetic material between two different genomes which is distinguished from a transfer of genetic material from parent to the offspring that is, vertical gene transfer.

For example, transformation, transduction, and conjugation result in horizontal gene transfer in bacteria.

It increases genetic variation of the population and plays important role in adaptation as well as evolution.

When a raw, shell-less egg was placed in sugar solution, the egg shrank. The egg was brought back to its original size by placing it in water. Which process does the experiment demonstrate?

Answers

The process that the experiment in question demonstrates is called Osmosis. It is the process in which a solvent moves from a region of higher concentration to a region of lower concentration through a semi permeable membrane. This way the concentration of the solution in both sides of the membrane becomes equal.

Answer:

osmosis
