Final answer:
The bottom layer of the ocean, known as the abyssal zone, lacks sunlight but is not devoid of living things. It has high salinity and cold water temperatures.
Step-by-step explanation:
The bottom layer of the ocean, also known as the abyssal zone, has no sunlight(A). It is the deepest part of the ocean where light cannot penetrate. However, despite the absence of sunlight, the bottom layer of the ocean is not devoid of living things(B). Many organisms have adapted to survive in this extreme environment, such as deep-sea fish, bacteria, and plankton. The bottom layer of the ocean is characterized by high salinity(C) and cold water temperatures(D). Additionally, it is important to note that conductivity(E) is present in the ocean as a measure of the water's ability to conduct electrical current.
