Answer: The correct answer for the first question is- B) Mechanical.
Adaptation can be described as a process of change in an organism over time that facilitates its survival in the changing environmental conditions. It results due to mutation or genetic change in the individual that gives a benefit to the organism. It exhibits change in structure ( like succulent plants in desert), function, or behavior.
Mechanical is not a type of adaptation as it deals with movement of objects.
The correct answer for second question is- C) Variations.
Variation among organisms in a population results from change in the genetic material or their genetic sequences. Change at the genetic level is thus reflected in the phenotypes ( like different color of feathers in birds).
Thus, difference is in the feather color reflects variations.
The answer to the above question is in a hot spring.
<h3>What is a habitat?</h3>
The term "habitat" in ecology refers to a region's collection of biotic, physical, and resource elements that are present to support a specific species' ability to survive and reproduce. It is possible to think of a species' habitat as the outward representation of its biological niche. As a result, "habitat" refers to a particular species, which is fundamentally distinct from ideas like "environment" or "vegetation assemblages," for which the term "habitat-type" is more applicable.

The correct answer is (B) chemosynthesis and marine snow are the two ways that organisms on the bottom of deep sea food chains acquire energy.
What is the meaning of chemosynthesis and marine show?
Chemosynthesis is the utilization of energy supplied by inorganic chemical processes to make food in bacteria and other organisms. To generate a sugar, all chemosynthetic organisms require energy provided by chemical processes, although various species employ different methods.
Marine snow is a shower of biological particles that falls from the upper ocean to the deep sea. Marine snow refers to biological material that descends from higher in the water column. Some flakes fall for several weeks before reaching the ocean floor.

this statement is False. prenatal development stages in order go from the germinal stage, embryonic stage, and the fetal stage, hope this helps :)
Answer and Explanation:
Today, the average proportion of fish production at a global scale used for human consumption is over 75 %. This has led to several disadvantages, such as overexploitation of fish and seafood, but to other advantages, such as aquaculture and economic improvement.
<em>Weaknesses</em>:
- Overfishing / overexploitation that leads to the significant decline of marine organisms.
- Noise pollution caused by fishing ships
- Waste and other pollutants that also increase marine contamination.
- An average person currently consumes almost twice as much seafood as half a century ago.
<em>Strengths</em>:
- The implementation of aquaculture.
- Higher economic gains
- More opportunities / jobs
