In the cells of most organisms, DNA is contained in the

a
cell wall
b
nucleus
c
ribosomes
d
lysosomes

Answers

Answer 1

Answer:

B. Nucleus

Explanation:

DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA). Mitochondria are structures within cells that convert the energy from food into a form that cells can use.

The information in DNA is stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T). Human DNA consists of about 3 billion bases, and more than 99 percent of those bases are the same in all people

Answers

B they are examples of weather

Temperature, cloud cover, and thunder are all the examples of weather. Thus, the correct option is B.

What are the weather conditions?

Weather is the state of the atmosphere. This is the degree to which it is hot or cold, wet or dry, calm or stormy, clear or cloudy at a geographical location. On the Earth, most weather phenomena occur in the lowest layer of the planet's atmosphere, the troposphere, just below the stratosphere of the Earth.

Weather refers to the day-to-day temperature, precipitation, and other atmospheric conditions, whereas the climate is the term for the averaging of atmospheric conditions over longer time periods.

Weather includes the sunshine, rain, cloud cover, winds, hail, snow, freezing rain, flooding, ice storms, thunderstorms, steady rains from a cold front or warm front, excessive heat, and heat waves.

Therefore, the correct option is B.
