Answer:

B. change natural marine life habitats.

Explanation:

Aquaculture or aquaculture is the set of activities, techniques and knowledge of breeding aquatic plant and animal species. It is an important economic activity of food production, raw materials for industrial and pharmaceutical use, and living organisms for repopulation or ornamentation. The farming systems are very diverse, from freshwater or seawater, and from cultivation directly in the environment to installations under fully controlled conditions. The most common crops correspond to planktonic organisms (microalgae7 and Artemia), macroalgae, molluscs and crustaceans, the professionals in charge of this work are Fisheries Engineers, Zootechnicians, Aquatic Engineers and Marine Biologists.

Fish farming is the breeding of fish, a term used to group a great diversity of crops that are very different from each other, generally denominated according to the species or the family. The facilities of industrial fish farming are known as fish farms, although this is a term in disuse, due to the diversification that has suffered the crop, in tanks, ponds, floating cages, etc. The most produced species worldwide are carp, salmon, tilapia and catfish.

Answer:

The layer that contains the youngest fossils is layer A.

Explanation:

In the picture, we have presented four layers and each of them contains one fossil. The rock layers are horizontally arranged and there isn't any disturbance to the layers. Without having disturbances, we have a situation of superposition, basically meaning that the rock layers are arranged in order by age.

The principle of superposition means that the bottom layer of rock strata is the oldest, while the top layer of rock strata is the younges, and all layers between them are arranged from top to bottom as younger to older. In this case, layer A is the one on top, thus it is the youngest layer of rock, and with it, the fossils it contains are the most recent as well. The fossil that we can see is most probably of a carnivorous dinosaur or a very large carnivorous reptilian.
