Small, but normal variations in genes may produce proteins that work differently from those of other individuals ( friends or relatives). This may affect how we respond to different medicines. The extent to which these proteins functions varies from one individual to another. Example; certain painkillers only work when body proteins convert them from an inactive form to an active one. If these proteins work too fast, the drug will be eliminated from the body before it has time to work. To do their job the pain killers need to bind and modulate a target body protein, the receptor, such that if the target body protein is altered the pain killer might not be able to bind.
Answer: definetly A, food webs
Explanation:
the other options are not even related to organisms
Answer:
They both contain multiple systems, which can be called organs or organelles, to function.
Explanation:
A single cell contains multiple small organs, called organelles, that give it energy and allow it to function as a living creature. Multicellular organisms are larger-scale versions of single-celled organisms, and while each cell has its own organelles, the larger organism has organs (such as the heart and lungs).
Photosynthesis is an example of an endergonic reaction. It is a type of reaction in which the energy is absorbed.
Photosynthesis refers to a set of reactions that uses solar energy, water and carbon dioxide in association with the pigment chlorophyll to produce organic compounds. Solar energy is converted into chemical energy in the form of ATP and NADPH. The chemical energy in these energy rich molecules is then used for the next step of photosynthesis for the fixation of the carbon.
Thus, photosynthesis is an endergonic reaction in which the solar energy is used to fix the carbon dioxide, transferring the energy into the carbohydrates formed and releasing oxygen.
