D. animals supply co2 to plants and plants supply o2 to animals :)
I don't know. But alleles is one or more alternative form of a gene, and recessive allele is two genetic genes that the offspring inherited from both parents.
The toxic still ended up to the affected people because of bioaccumulation. This means that organisms who might have consumed the said mercury was consumed by some larger organisms. These larger organisms were eaten or consumed by human beings. The toxin, in other words, was just passed on to different species.
Answer:
Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy from oxygen molecules or nutrients into adenosine triphosphate (ATP), and then release waste products. The reactions involved in respiration are catabolic reactions, which break large molecules into smaller ones, releasing energy because weak high-energy bonds, in particular in molecular oxygen, are replaced by stronger bonds in the products. Respiration is one of the key ways a cell releases chemical energy to fuel cellular activity. The overall reaction occurs in a series of biochemical steps, some of which are redox reactions. Although cellular respiration is technically a combustion reaction, it clearly does not resemble one when it occurs in a living cell because of the slow, controlled release of energy from the series of reactions.
Answer: Precipitation -> evaporation -> condensation
Explanation: precipitation is when it rains, so water is delivered by the atmosphere into the ocean. Evaporation happens when water in the ocean is heated up and returned to the atmosphere. Condensation occurs when water condenses due to pressure/temp differences creating clouds.
