The answer to your question is C- colder , saltier , and denser why because they don't have the same density level and deep ocean water is more dense than surface. and also From
your feet to your knees the water feels icy cold and from your knees to your head the water feels
warm. You probably wondered what causes this to happen. What you felt were warm surface
currents and cold deep currents. Changes in the density set these currents in motion. some ocean currents are set in motion by the wind other ocean currents are created by something you can't feel or see. Differences in density of water can also cause currents to form and move. Density is affected by temperature and salinity. i hoped i helped
Answer:
D

D is the best answer, as it’s the only true statement. The circulatory system consists of your blood, blood vessels, and heart. The system is mainly responsible for delivering nutrients and oxygen to your cells and removing waste like carbon dioxide.
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.
