13) Crossing over is important because it creates ___.
Ainat [17]

Crossing over is important because it creates genetic variability.

<h3>What is crossing over?</h3>

It is the exchange of chromosomal segments between non-homologous chromosomes in a tetrad.

Since chromosomal segments contain genes at different loci, the exchange will increase the genetic variability of the new chromosomes.

Thus, the daughter cells carrying the recombined chromosomes will be genetically variable from not just the parent cell, but fellow daughter cells.

Why factors are cause of short-term climate change
laiz [17]

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.
