Write 1-2 paragraphs explain the following concept: convection currents in fluids, wind, global winds , local winds, sea breeze, land breeze, jet streams, trade winds,

Convection currents in fluids - ok so, convection currents rely on the constant cyclical motion of air, water and other substances to distribute heat, they form because a heated fluid expands becoming less-dense, the less dense rises away from the heat source as it rises it pulls cooler fluids down to replace it.

Wind - moving air and is caused by differences in air pressure within our atmosphere. Air under high pressure moves toward areas of low pressure. The greater the difference in pressure, the faster the air flows.

Global Wind - These winds occur in belts that go around the planet they are caused by the unequal heating of the atmosphere(the earth's surface) the warm air rises at the equator and moves toward the poles. At the poles, the cooler air sinks and moves back toward the equator, which is caused by the Coriolis effect because it causes global winds to move on a diagonal over the surface.

Local winds - local winds blow over a limited area, they blow between small and high-pressure systems (sea to land) this keep the coastal temperature milder so they affect the weather and climate of a region, they are happening predictably way because they have a particular local area.

Sea breeze - Blowing breeze from the sea towards land during the day, it is classified as a local wind. At high temperatures, the air becomes lighter and rises, the air on the land is at high temperature so it starts blowing towards the sea.

Land breeze - coastal breeze at night blowing from the land to the ocean which is caused by the difference in the rates of cooling of the land and the ocean. so it is a local nighttime and early morning wind that occurs along coasts and blows offshore (from the land to the sea). It arises at sunset when the sea surface is warmer than the adjacent land due to the land having a lower heat capacity and cooling off faster.

Jet streams - relatively narrow bands of strong wind in the upper levels of the atmosphere. they follow the boundaries between hot and cold air, the warm air rising at the equator will move toward both poles. they form when warm air masses meet cold air masses in the atmosphere. so it is basically a narrow current of strong winds high above the earth that moves from west to east. 

Trade winds - permanent east-to-west prevailing winds that flow in the Earth's equatorial region. so it is a wind blowing steadily towards the equator from the north-east in the northern hemisphere or the south-east in the southern hemisphere, especially at sea. Two belts of trade winds encircle the earth, blowing from the tropical high-pressure belts to the low-pressure zone at the equator.

I really hope this helps

under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.

i think? ?

the right answer is c i just did the question.
