Answer:
The correct answer is option A. restriction enzymes.
Explanation:
Restriction enzymes or restriction endonucleases are enzymes that identify a particular DNA sequence, knowns as restriction site, and cuts the DNA within or adjacent to restriction site.
Restriction enzymes also known as biological scissors because of their ability to cut DNA at a specific sequence.
EcoR I, isolated from the bacterium Escherichia coli, is a restriction enzyme that restricts DNA between the G and A on each strand in a particular DNA sequence.
Thus, The correct answer is option A. restriction enzymes.
The runner's body will create all of the needed energy through fermentation.
The runner's body will supply all of the needed energy through cellular respiration.
The runner's body will produce the ATP that is required through glycolysis.
B. green, purple, and red
C. red, green, and blue
D.black, brown, and white
According to the trichromatic theory of color vision, the eye has cones sensitive to colors associated with red, green, and blue. Therefore, option "C" is correct. According to the trichromatic theory of color vision, the human eye perceives only three hues of light which are green, red, and blue.
Every color in the visible light spectrum can be produced by combining the wavelengths of these three colors. Thomas Young first proposed trichromatic theory, and Hermann Von Helmholtz later tested it. Each of these three kinds of cones responds to distinct wavelengths of light, which, when combined, can be used to produce all of the colors in the visual spectrum.

Answer:
A macromolecule is a very large molecule, such as protein, commonly composed of the polymerization of smaller subunits called monomers. They are typically composed of thousands of atoms or more. A substance that is composed of monomers is called a polymer .
Explanation:
The given question - 'Is the lifespan of the snowshoe hares which are white in winter and brown in summer affected by levels of winter snowfall?' is a good scientific question. This question is very specific about the query. Moreover, the query asked in the question can be answered using the scientific testing methods. A hypothesis can be formed based on the question which can be tested.
Hence, it is a good scientific question.
Cell respiration occurs in animal cells and not plant cells.
Photosynthesis uses chemical energy as energy source, and cell respiration uses light energy.
Photosynthesis uses light as energy source, and cell respiration uses chemical energy.
Correct answer: Photosynthesis uses light as energy source, and cell respiration uses chemical energy
Photosynthesis is a light dependent process in which green plants and certain other organism convert light energy in to chemical energy. In this process sunlight is uses to to convert water and carbon dioxide into ATP molecule which are needed for growth.
Cellular respiration is metabolic process that occurs inside the mitochondria of the cell to convert biochemical energy which is derived from nutrients into ATP (Adenosine triphosphate) and removal of waste products.
Photosynthesis uses light as an energy source, while cell respiration uses chemical energy. Therefore option d. is the correct answer.
The correct statement that distinguishes photosynthesis and respiration is:
Photosynthesis uses light as an energy source, and cell respiration uses chemical energy.
In photosynthesis, plants convert light energy into chemical energy, specifically glucose. This process occurs in the chloroplasts of plant cells.
On the other hand, cell respiration is the process by which cells break down glucose to release energy in the form of ATP (adenosine triphosphate).
This process occurs in both plant and animal cells, specifically in the mitochondria.
Therefore, photosynthesis uses light as its energy source, while cell respiration uses chemical energy.
Therefore option d. is the correct answer.
