Answer:
6 factors that cause short term climate change...
Explanation:
Latitude - depends on how far or close to the equator it is
Ocean currents - Certain ocean currents have different temperatures.
Wind and air masses. Heated ground causes air to rise which results in lower air pressure. As it rises it cools and descends to the ground resulting in high air pressure.
Elevation. The higher up you are, the colder and drier it will be. When air rises it expands due to low air pressure which causes it to cool.
Relief. The differences in the elevation inland. As air is forced to rise over a piece of land, the temperature decreases and condensation increases.
Nearness to water. The water heats up and cools down slower than land does, having a moderating effect. On colder days, the water heats up the land, whereas on hotter days, the land is cooled down by the water.

Like a prokaryotic cell, a eukaryotic cell has a plasma membrane, cytoplasm, and ribosomes. However, unlike prokaryotic cells, eukaryotic cells have: a membrane-bound nucleus. numerous membrane-bound organelles (including the endoplasmic reticulum, Golgi apparatus, chloroplasts, and mitochondria)
Rough ER is studded with ribosomes and the Smooth ER has a smooth surface ..
