Answer:
Primary active transport
Explanation:
Primary active transport is the transport in which molecules are moved against their gradient, with direct use of ATP as an energy source. Na/K pump is an example of primary active transport: Na ions are transported out of cell, K ions are moved into the cell. This pumps maintain concentrations of those ions and also creates voltage across the cell membrane, which can be used for the secondary active transport of other molecules (e.g. glucose).
Grasses are the producers. Gazelles, warthogs, and wildebeests are primary consumers. Lions and cheetahs would be the secondary consumers.
Please provide an image. But just for reference, a plant cell's main organelles are the cell wall, cell membrane, large water vacuole, nucleus, mitochondria, cloroplast, lysosme, golgi body, and some other organelles that may also be found in animal cells.
Which of the chemical where are the chemical
I am not sure if this question means the adjective form or the adjacent form? However, a Schwann cell is a type of glial cell and its main function is to support neurons. Adjacent to the Schwann cell are nodes of Ranvier which are gaps in the myelinated axons, and are believed to assist in potential generation among other things.
