Answer:
The Answer Is B . I Think
Answer:
A. Location
Explanation:
A black hole is a massive structure in the space from which light cannot escape. Therefore, <u>the depth of the black hole (B), the speed (C), and size (D) are extremely difficult to measure</u>. However, scientists have been able to locate the position of black holes via the movement of stars and gases around it. Typically, since black holes are extremely dense objects, masses spins around the black holes and form a structure called an accretion disk. By looking at the speed of stars, the scientists can detect where the black holes are in the space.
The organisms that live in the dark zone survive through a food chain, just like everything else on this planet. Food can sometimes get into a cave through natural weather events like flooding, flooding can lead all sorts of leaves and plants into the cave, giving insects and animals that live there food to eat. Guano (Bat feces) can also be eaten, bacteria and fungi can decompose it into basic food.
Enzyme. An enzyme is a biological catalyst and is almost always a protein. It speeds up the rate of a specific chemical reaction in the cell.
In molecular biology, the term double helix refers to the structure formed by double-stranded molecules of nucleic acids such as DNA. The double helical structure of a nucleic acid complex arises as a consequence of its secondary structure, and is a fundamental component in determining its tertiary structure.
