Answer:
c) Amino acids
Explanation:
Proteins are long-chain molecules made of amino acids. They are linked through a covalent peptide bond. Therefore, the option (c) is the correct answer.
Answer:
The given blank can be filled with acid.
Explanation:
Acid deposition or acid rain refers to a broad term that comprises any kind of precipitation with acidic constituents like nitric acid or sulfuric acid, which falls to the ground from the atmosphere in dry or wet condition. This can fall in the form of snow, rain, hail, fog, or even dust, which is acidic. When sulfur dioxide reacts with water vapors, they give rise to sulfuric acid, and identically when nitrous oxide reacts with water vapors it produces nitric acids, which transforms the water of rain into acidic form.
Answer
the food chain the answer has to do with trophic levels as you probably know the organisms as the base of the food chain are photosynthetic plants on land and in the oceans these organisms are called the producers and they get their energy directly from sunlight and inorganic nutrients the organisms that eat the producers are primary consumers they tend to them to be small in size and there are many of the primary consumers RRB waris vegetarians their organisations that that eat the primary consumer or meat eaters coronavirus and are called the secondary consumers that the secondary consumer strength to be a larger and fear in number this continues on all the way up to the top of the food chain about 50 percentage of the energy possibly as much as 90 % of in the food is lost at the at each chapter 1 level when an organism is eaten so it is less efficient to be a higher order consumer that rather than have a primary consumer therefore the energy transfer from one trophic level to the next up the food chain is like a private pyramid wider at the top
