The nucleus intructs cells to do their activities
First, weather is the atmospheric condition occurring over a short period of time in a relatively small location. Climate, on the other hand, is the overall environmental condition over extended periods of time. Next, the water cycle is when water from the surface evaporates as water vapor under high temperatures and condenses in the atmosphere under lower temperatures and precipitates back to the surface. In the event that water evaporates more than it condenses then the weather will be warm to hot, the ground will be relatively dry, and drought over extender periods of time may ensue. On the other hand, if water condenses and precipitates more than it evaporates, then there will be a rainy season, and may extremely lead to landslides and floods.
Answer:
Change in the structure of chromosome.
Explanation:
Chromosome structure mutations are the changes that occur in the structure of chromosomes rather than just individual nucleotides. These mutations occurs due to the errors that happens in cell division that leads to the breaking in section of a chromosome, which can be duplicated or move onto another chromosome. Chromosome mutation is the process of change in the chromosomes that occurs due to the rearranged chromosome parts and abnormal numbers of individual chromosomes.
A. In prophase I, tetrads of homologous chromosomes form and crossing over occurs
