The statement is - True.
The humans, as advanced and developed they may be, can not function and survive without the proper functioning of the biosphere, hydrosphere, atmosphere, geosphere, cryosphere. All of those spheres are crucial in defining the life conditions on our planet, and the human kind, as all other living organisms, is heavily dependent upon them.
Unfortunately, the humans have been interfering a lot in the functioning of this systems, and make it harder and harder for them to function properly, and the interfering with the ecological systems is extremely dangerous as it can have a catastrophic consequences.
Active transport is the movement of dissolved molecules into or out of a cell through the cell membrane, from a region of lower concentration to a region of higher concentration. The particles move against the concentration gradient , using energy released during respiration .
Answer:
plasma membrane of the target cell
Explanation:
There are two main types of acetylcholine (ACh)receptors:
- muscarinic ACh receptors (because muscarin as agonist) which are G-protein coupled receptors that initiate slow response. Mostly, they are located in the central nervous system-CNS (involved in the release of neurotransmitters), heart (control of the heart rate), smooth muscles (contraction).
- nicotinic ACh receptors (nicotin is agonist) which are ligand-gated ion channels involved in the fast response. They are located at neuromuscular junctions but also in CNS (involved in synaptic transmission between two neurons).
Answer: This might be helpful because t is a good basis for organizing elements because each element has a unique number of protons and atomic mass is an indirect way of organizing elements by number of protons.
Since frogs consume plants, it needs to have a longer small intestine so the food has more time to digest and be absorbed because the small intestine helps enthrall nutrients and calories from digested food, so it needs to be long enough so it can go through full digestion.
