Answer:
Explanation:
Dna is shaped as a double helix and has weak hydrogen bonds. They contain complementary base pairs (adenine and thymine) and (guanine and cytosine).
Hope this helps.
Ocean trenches are deep sections of the ocean where an oceanic plate is usually sinking below a continental plate. How are they formed? They are formed in the subduction zone as the denser oceanic plate is subjected under the continental plate.
False, aerobic respiration creates lactic acid as a by product but produces far more ATP than respiration. When lactic acid is ferment by certain bacteria which includes the bacteria in yogurt and also by human muscles cells when they are worked hard and fast.
In aerobic cell respiration which includes glycolysis + the kerbers cycle = respiratory electron transport that produce 36 ATP /glucose consumed. Aerobic respiration cell are 18 times more efficient than anaerobic cell respiration because in aerobic respiration more ATP than anaerobic respiration due to the complete oxidation of glucose to CO2 and water .
Now O2 acts as terminal electron accept in this electron transport chain and gets reduced to water.ATP are produced by oxidation phosphorylation in the electron transport chain.

Answer:
1.)Carbohydrates
2.) Lipids
3.)Proteins
4.)Nucleic acids
Explanation:
1. Carbohydrates
The major carbohydrates found in cell walls are cellulose, hemicellulose and pectin. The cellulose microfibrils are bonded through hemicellulosic tethers to give the cellulose-hemicellulose network, that is found in the pectin matrix.
2. Lipids
Cell membrane are majorly made up of phospholipids, glycolipids, proteins, and cholesterol. The lipid found mostly though our the membrane are the phospholipids.
3. Enzymes/proteins
Enzymes are biological molecules that are protein in nature and accelerate the rate of the chemical reactions that occurs within cells.
4. Nucleic Acid
Nucleic acids aid major activities in the cell by serving as the repository of the genetic materials needed for the transfer of inherited characteristics from parents to offspring and from an individual cell to another cell
