Since our bodies are made up of 70 percent water, we need water to keep us from dehydrating, food is important because it has the nutrients and proteins that our bodies need to repair, grow, and keep healthy, and oxygen is also important because it gets carried throughout our blood stream and oxygenates our muscles, without any of these, we would die within a few weeks
Cell membranes serve as barriers and gatekeepers. They are semi-permeable, which means that some molecules can diffuse across the lipid bilayer but others cannot. Small hydrophobic molecules and gases like oxygen and carbon dioxide cross membranes rapidly.
Plants are a part of nature, they breed and have yarns of space to grow
The best I have is that the cold air is at the bottom and the warm air is at the top.
The correct answer is the spray zone.
The upper littoral, also known as the spray zone, or the splash zone. This region is dry for the majority of the time, however, gets sprayed with salt water at the time of high tides. It is only flooded at the time of extreme high tides and storms. The species in this scarce habitat comprise isopods, barnacles, limpets, lichens, lice, whelks, and periwinkles.
