Answer: All the statements are true.
Sugar and O2 is produced In photosynthesis, Sugar and O2 is consumed in respiration and energy is required in photosynthesis.
Explanation:
Photosynthesis this is a process whereby green plants use energy from sunlight to convert carbon dioxide and water to sugar and oxygen.
While Respiration is the process whereby sugar produced during photosynthesis combines with oxygen to produce usable energy for cells.
Answer:
Animals and plants need nitrogen to build amino acids in proteins, which are the building blocks of life. Unlike oxygen, nitrogen cannot be absorbed directly from the air by animals and plants.
Explanation:
Answer:
specificity
Explanation:
Enzymes are proteins with high specificity, ie each catalyzes only one type of chemical reaction, or a small number of reactions. This is due to its shape, which presents on the surface molecular fittings, the active sites or centers where the substrates or reagents attach. An example of this is the ability of an enzyme to select a specific substrate from the myriad of molecules floating around its environment.
Therefore, substrates other than those that fit into the active sites of a specific enzyme cannot be part of that reaction, there must be another enzyme to catalyze its reaction. The specificity of enzymes for their substrates is similar to the specificity between a lock and its key.
Plant cells have several structures not found in other eukaryotes. In particular, organelles called chloroplasts allow plants to capture the energy of the Sun in energy-rich molecules; cell walls allow plants to have rigid structures as varied as wood trunks and supple leaves; and vacuoles allow plant cells to change size.
The answer is A. Think of stomach acid when you think of pH the stomach acid degrades and mushes the food up making it easier to digest. So acid rain will make the water acidic hurting the environment
