What is cell?All living organisms are made up of cells, which are the basic building components. There are billions of cells in the human body. They support the body's structure, absorb nutrients from meals, transform those nutrients to energy, and perform specific activities. Cells also carry the body's genetic material and have the ability to replicate themselves.A cell is a cytoplasmic mass that is outwardly bound by a cell membrane. Cells are the smallest structural units of living matter and make up all living things. They are usually tiny in size. Most cells have one or more nuclei, as well as additional organelles that perform various functions.In unicellular and multicellular organisms, cells act differently. A unicellular creature relies on only one cell to conduct all of its duties. A multicellular organism contains cells that specialize in distinct roles and work together to maintain the organism.

What is a nucleotide base?

A nucleotide is the monomer constituting DNA or RNA biopolymer molecules.

Each nucleotide consists of a nitrogenous heterocyclic base (or nucleobase), which can be either a double-ringed purine or a single-ringed pyrimidine; a five-carbon pentose sugar (deoxyribose in DNA or ribose in RNA); and a phosphate group.

The two classes of nitrogenous bases are purines and pyrimidines and they are as follows;

Purines - Adenine and GuaninePyrimidines - Cytosine, Uracil, Thymine

What is the use of reverse transcriptase?

Reverse transcriptase enzyme has been generally used by the retrovirus for their genome replication. This enzyme has been discovered by the Howard tenim.

Reverse transcriptase enzyme generates the complementary DNA from the mRNA template by the process of reverse transcription. The presence of RNase H, RNA-dependent DNA polymerase and  DNA-dependent DNA polymerase activity enable the enzyme to convert the mRNA into DNA.

The position of the mRNA is to carry protein facts from the DNA in a cell's nucleus to the cellular's cytoplasm (watery interior), where the protein-making machinery reads the mRNA sequence and translates every three-base codon into its corresponding amino acid in a growing protein chain.

Therefore, The mRNA sequence will best match the section of DNA shown below is  C-U-A-G-G-A. Thus, option C is correct.

Astronauts on a spaceship in outer space notice their instruments detect energy from the Sun. Which of the following provides evidence that the Sun’s energy is moving through outer space?
A. Molecular collisions of visible light and infrared radiation
B. Electromagnetic radiation in the form of radio waves
C. Electromagnetic radiation in the form of matter
D. Molecular collisions of gas atoms

Answers

I believe the answer is B. Electromagnetic radiation in the form of radio waves. (Please Mark brainliest if correct )

The statement that provides evidence that the Sun’s energy is moving through outer space is electromagnetic radiation in the form of radio waves.

What do you mean by Radio waves?

Radio waves may be defined as electromagnetic waves enclosing a wavelength between 1 millimeter and 30,000 meters, or a frequency between 10 kilohertz and 300,000 megahertz. These waves are used in radio, television, and satellite communications.

The Sun's energy consists of UV radiations but these radiations are not consumed by radio waves, resulting in the consumption of electromagnetic radiation on the Earth's surface.

Therefore, the statement that provides evidence that the Sun’s energy is moving through outer space is electromagnetic radiation in the form of radio waves.
