Answer:
Active Transport: Active transport pumps molecules through the cell membrane against the concentration gradient.
Passive transport, also known as passive diffusion, is a process by which an ion or molecule passes through a cell wall via a concentration gradient, or from an area of high concentration to an area of low concentration.

Answer:
FALSE. because why would something be wrong of it is supported by credible evidence, but if it stated the hypothesis along with the evidence and the evidence isn’t as credible then it could be true but only in that case.
Explanation:
Sea floor sediment provide an invaluable key to past climate change. Finely varved sediments from areas of rapid deposition provide a high-resolution record of past climate variation, and volcanic ash layers contribute to the comprehensive study of climate change on relatively short timescales. Oceanographers like to say that we know more about the dark side of the Moon than we do about the oceans. That statement is doubly true of the seafloor. Although modern technology has allowed us to learn more about the seafloor, vast regions remain unexplored. Scuba divers can only dive to about 40 meters and they cannot stay down there for very long. Although this is good for researching the organisms and ecosystems very near a coast, most oceanic research requires accessing greater depths.
Question #1: D
Question #2: B
These are the correct answers hopefully. I knew the second one, but the first one I had to look up and do a wee bit of research
