Sinks; clear: dry.

Explanation:

Weather can be defined as the atmospheric conditions of a particular area over a short period of time.

The elements of weather include precipitation, wind, temperature, atmospheric pressure, relative humidity, cloud, and wind speed.

The air pressure gradient which typically is the difference in air pressure between two systems affects the movement of atmospheric air. Consequently, this movement has a significant level of impact on the type of weather that is formed between low-pressure and high-pressure systems.

In a high pressure system, cool air sinks and warms, and the weather is clear and dry. Similarly, in low-pressure systems, warm air usually rises and then cools, thus, leading to the formation of clouds and precipitations.

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.
