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
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.

How would you demonstrate that all cells come from preexisting cells
Answer: The generally accepted parts of modern cell theory include: ... All living cells arise from pre-existing cells by division. The cell is the fundamental unit of structure and function in all living organisms. The activity of an organism depends on the total activity of independent cells.
Explanation:
To demonstrate that all cells come from pre-existing cells, you should: Observe a bacterium performing binary fission to form clones of itself.
A cell can be defined as the basic functional, structural and smallest unit of life which is found in all living organisms.
According to cell theory, the following statements are true about cells;
All living organisms comprises small structural units called cells.A cell is the fundamental (basic), functional unit of life.Every living organism is made up of one or more cells: unicellular or multicellular.All cells are produced from existing (other) cells i.e pre-existing cells produce new ones through a process called cell division.Binary fission is an asexual reproduction wherein the body of a prokaryotic organism such as bacterium, is divided into two (2) new identical bodies.
In order to demonstrate that all cells come from pre-existing cells, you should observe a bacterium performing binary fission (dividing) to form clones of itself.
In conclusion, the chromosome (pre-existing cell) of a bacterium containing deoxyribonucleic acid (DNA) and associated proteins replicates and then divides in half to form clones of itself (identical daughter cells).

Explanation:
took the quiz this question right with this answer
The mRNA sequence will best match the section of DNA shown below is C-U-A-G-G-A. Thus, option C is correct.
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.

What process forms stalactites and stalagmites?
Answer:
As the redeposited minerals build up after countless water drops, a stalactite is formed. If the water that drops to the floor of the cave still has some dissolved calcite in it, it can deposit more dissolved calcite there, forming a stalagmite.
What is a gene? a single strand of DNA. the fundamental unit of heredity. a single nucleotide. the fundamental unit of DNA
Answer:
the fundamental unit of heredity
Explanation:
DNA is a double stranded helix structure. Each strand is made up of a string of nucleotides.
A gene is a region of DNA, usually tens of thousands of nucleotides long. At the simplest level, one gene encodes for one trait. Therefore, the gene can be described as the fundamental unit of heredity.
Genes work by coding for specific proteins, which carry out essentially all the functions in the cell.

How did Claire's digestion reaction weights tell you that the problem was in her small intestine, and not in her stomach
Answer:
The reaction rate of the digestion helps in understanding which part of the digestive system having trouble in digestion especialy stomach and intenstine related.
It involves the fact that most of the enrgy or calories are get by the small intestine and also vitamins and minerals are absorbed by this part of the digestive system so if the small intestine is having problem the rate of digestion would be affected and and an individual could be malabosrbed.
If the problem lies in the stomach it might show some effects of a poor digestion, however the rate of digestion would be better than if the problem lies in the small intestine.

which of the following?
O convert solar energy to chemical energy
Odigest metabolic wastes in the organelle
O produce ATP during cellular respiration
move the cell through water
Answer:
convert solar energy to chemical
Explanation:
the mitochondria is the power house of the cell
The folds greatly increase the membrane's surface area. This improves the ability of the mitochondrion to produce ATP during cellular respiration. Thus, the correct option is C.
What is Cellular respiration?Cellular respiration is the process through which biological fuels are oxidized in the presence of an inorganic electron acceptor in the cell such as oxygen to produce large amounts of energy, to drive the bulk production of ATP (Adenosine triphosphate) in the mitochondria.
A large number of folds are present in the mitochondrial membrane to increase the capacity of the mitochondrion to synthesize ATP molecules, the inner membrane of the mitochondria is folded to form cristae in the membrane. These folds allow a much greater amount of electron transport chain (ETC) enzymes and ATP synthase to be packed into the mitochondrion membrane.
Therefore, the correct option is C.
