Explanation:
Metamorphism describes how one type of rock is changed into another. Schist, a metamorphic rock is produced by adding heat and pressure to mudstone or shale, thus it is metamorphic; the extreme pressures during its creation fire the quartz grains, flat minerals and feldspar into large-grained rock. As metamorphism increases, i.e. pressure and temperature, the size of the crystals and how coarse the folding or foliation increases.

When something is cooled, its atoms compact and become more dense. vice versa for heating
Answer: omega 3's
Explanation:
-combination of marine & food biotechnology
-polyunstaturated fatty acids (PUFAs)
-3 types in human physiology
->α-linolenic acid (ALA) - found in plant oils
->eicosapentaenoic acid (EPA)
->docosahexaenoic acid (DHA)
-N-3 fatty acids have health benefits & are considered essential fatty acids, meaning that they cannot be synthesized by the human body - but are vital for normal metabolism
->table of dietary source of Omega-3
-->fish is commonly used but dangerous as you can contract mercury poisoning
Answer:
C) The main predator of these fish is another species of fish on which alligators also prey
Explanation:
The only reasonable explanation as to why the species of fish experiences decline in number despite the fishing being the same, and the number of alligators that preyed on the fish going down, is another species of fish which preyed upon the fishes that are fished, but the alligators were also preying on them. Since the alligators have been mostly removed from the ecosystem, the fish that preyed on the other fishes experienced significant increase in its numbers, and since it feeds upon the other fish, that resulted in constant decline in the population of those fishes. The decline in number will only stop when the carrying capacity is reached for the predatory fish in the ecosystem.
The fossil record is used to divide Earth's history into geologic time periods. The figure below shows the four major subdivisions of geologic time—eons, eras, periods, and epochs. Eons are the longest subdivision and are based on the abundance of certain fossils. Eons are divided into smaller time periods called eras
