Answer:
By changing pyruvate into lactic acid with this transfer of electrons.
Explanation:
Transfer of electrons helps the lactic acid fermentation process repeat itself because the pyruvate molecule takes electron from NADH which is reduced to lactic acid so indirectly with the transfer of electrons helps the lactic acid fermentation process to repeat itself. If these electrons are not transferred from NADH to pyruvate molecules so the lactic acid is not formed.
These are few examples of ecosystem services. These are conditions or processes of natural systems that directly or indirectly have a benefit to humans or enhance their social welfare. They include purification of water and air, maintenance of biodiversity, soil and vegetation generation and renewal, seed dispersal, greenhouse gas mitigation among other services.
Answer:
A) It uses less energy to make something from recycled materials than from new materials.
Explanation:
When a recycled material is used to make a new product, it conserves energy because the recycled materials have already been processed once; so making something from it for the second time uses less energy-intensive than the first. For example: Making new aluminium from old products uses 95% less energy than making it from scratch.
Hence, the correct answer is "A)"
Answer:
When light energy is absorbed by a chlorophyll molecule its electrons gain energy and move to higher energy levels in the molecule
