Answer:
The correct answer will be option-E
Explanation:
The structure of DNA revealed by Watson and Crick showed that Two strands of DNA are present in the intertwined state forming helix representing DNA as a double helix.
Each strand of DNA is made up of the monomer unit of DNA called nucleotide where each nucleotide binds to another nucleotide through weak covalent bond called phosphodiester bond.
The phosphodiester bond is formed between the 3’-OH group of one nucleotide to 5’ phosphate group of another nucleotide. In this way, the phosphate-sugar molecule forms the backbone of the DNA molecule.
Thus, option-E is the correct answer
A whole number ratio; Hopefully that is the answer if you need an actual number the best guess would be 2:1.
Answer:
Hydrogen bonding between water molecules allows water to be <u>cohesive.</u> This property of water allows it to rise from a plant's roots to its highest branches.
Explanation:
Cohesion is that force of attraction between molecules that holds the particles of a substance together with others of the same type. It is said that a liquid has more or less cohesion, depending on whether its molecules are more or less attracted to each other. In water, the cohesion force is high because of the hydrogen bonds that hold the water molecules tightly bound together, forming a compact structure. For example, in plants, it is essential that the water column be kept continuous, so that the tension of the xylem (conductive plant tissue) is transmitted to the root. The water column is held together thanks to the powerful cohesion forces that attract water molecules together.
Answer:
The sympathetic nervous system activates what is often termed the fight or flight response. Like other parts of the nervous system, the sympathetic nervous system operates through a series of interconnected neurons.
Explanation:
To generate ATP
The chloroplasts' thylakoid membrane experiences a light reaction. Both cyclic and noncyclic photophosphorylation is involved. During the photochemical phase of photosynthesis, photophosphorylation is the process of producing ATP from ADP and H3PO4 in the presence of light and chlorophyll-a.
ATP is created during cyclic photophosphorylation, and ATP and NADPH2 are produced during non-cyclic photophosphorylation. As water is photolyzed, oxygen is also created.
Therefore, ATP, NADPH2, and O2 are the byproducts of the light process.
By releasing its phosphate groups, the coenzyme ATP helps enzymes like ATP triphosphatase transmit energy to cells.
Therefore, ATP is frequently referred to as the "energy currency of the cell" by biologists. From a biological standpoint, ATP is made up of three parts.
