Neurons that carry information away from the central nervous system are called motor (or efferent) neurons.
Quadrat method is used for estimating the number of individuals in an area. In this method, a large square area on the ground or water surface is marked, call it an enclave. The number of animals present in this enclave is counted. Then by assuming that the animals are less migratory and are uniformly distributed, their number for a large area is estimated by the use of unitary method of calculation. Example a 4 square feet area has 2 snails, then a 1000 square feet area will have (1000 x 2)/4, i.e, 500 snails in it. Fishes can be counted using this method only if they are confined in a small water body like a lake or a pond. Rivers are flowing so the fishes may move along its length which can give us an underestimate or an overestimate of their numbers. Sea has its depth and huge area, and fishes can be moving randomly in it. Hence this method will not work for river and sea fishes.
The answer is D. The last one.
glucose is a chemical compound made of 6 atoms of carbon 6 atoms of oxygen and 12 atoms of hydrogen.
No, it is not alive because water is a non-living thing. Aka it doesn't have cells or organs. The fact that it rolls up on the beach all depends on wind and the gravitational pull of the Earth.
A system is a group of organs that work together and provide an organism with an advantage for survival. It is the most complex organization in your body and the final level of the progression from cells to tissues to organs and then systems.
