Answer:
The phenomenon seen by the students is Osmosis.
Explanation:
Osmosis is the movement of molecules from higher concentration to lower concentration through a semi-permeable membrane. This type of movement of molecules occurs in the body cells. When the concentration of molecules is higher outside the cell than the inside, the molecules goes inside the cell through semi-permeable membrane.
Answer:
Jennifer observes a weather map showing tomorrow's weather. She predicts that air will travel from the high pressure system to the low pressure system, causing wind. The wind will carry moisture since it is coming from the ocean.
Explanation:
Winds refers to the movement of air which are produced due to differences in air pressure.
These pressure differences are to uneven heating of the earth by the sun. Due to the uneven shape of the earth, regions around the equator receive a fairly consistent heating from the Sun. However, with increase in latitude north and south, there is more uneven heating of the earth's surface by the Sun. When air is heated, warm air rises up to the atmosphere. This produces a pressure difference and subsequently cold air sinks downward to replace it. This constant air movement results in winds. The winds generated moves from a high pressure system to a low pressure system. The greater the pressure difference, the greater the wind force.
When warm air from land rises, air from the ocean in to replace it. The wind coming from the ocean is moisture-laden, and results in precipation on land.
Beause we cut down a lot of trees. Often, so many, that the health of a forest is irreparably damaged. A forest is not just a bunch of trees. It is a whole ecosystem, in which the trees anchor the growth of many other plant and animal species, hold the ground together to prevent erosion, and produce a lot of oxygen to support animal life. If you harvest too many of the trees, the local ecosystem stops being a forest and starts turning into something else
Answer:
the circulatory system provides the the skeletal system with nutrients within blood and aids in keeping muscles ligaments and tendons oxygenated.
