Correct question: A fast swimming strong body fish such as a <u>salmon</u> which is adapted to clear fast and strong water current would most likely be found in which aquatic zone? Options in the attached file
Answer:
Source of a river zone
Explanation:
The fishes body is directly correlated with their environment and the pressures they receive from it. Those animals that are used to living in clear waters, with fast currents must be very strong, must have a hydrodynamic torpedo-like body and big and strong caudal fin to propel against the currents. These animals are used to living in water masses such as the source of a river zone.
Rivers belong to lotic environments, characterized by constant moving water.
- Profundal zone: Sunlight can not reach this zone, so there are no plants. The Water movement is very limited, and in most cases, water is not clear.
- Littoral zone: Is the transition zone, near the shore, where the light easily reaches the bottom. Usually, there is plenty of vegetation fixated to the bottom.
- Wetland zone: In general these are calm water, very rich in diversity, and a proper breeding area for a wide variety of fish.
- Source of a River zone: Rivers flow from higher to lower areas. They originate at the top of the mountains and fastly descend to finally end in a lake or in the sea.
Some species of salmons characterize by living in the sea during sexual maturity, but whenever they need to breed, they go back to the area where they were born. This is in sweet water. They swim in the river until they reach the place where they are going to oviposit. In order to do this, they need to swim against the current. Many times, females die trying to reach this special place.
The answer to this question would be: visceral motor
The muscle in the stomach is not consciously moved. The muscle regulated automatically by the nervous system based on some mechanism like other organs. The things that can influence the muscle would be when the autonomous nervous system is activated. This kind of motor innervation is called visceral motor.

Answer:
the correct answer is B) Hydro Pods
Explanation:
Hydroponic Pods are miniature farms that can fit indoors even in a rented apartment and which enables one to grow their foods indoors.
It is designed to enable one to grow plants using water, and nutrients only. No soil is required. Often, the plant's nutrition comes in already made solutions. This system of farming occupies far less space than traditional farming methods.
