Those changes in an individuals' genotype that ensure genetic variation begin to be done in Metaphase, where chromosomes are aligned to the equatorial axis of the cell, and eventually, each chromosome is pulled to each pole of the cell during Anaphase I. After this process, follows telophase I, where we can say that each chromosome is given to each of the two daughter cells. We can say then that the creation of different versions of alleles begins with Telophase I.
The trends that shows the increasing use of renewable energy are:
- Houses and cars powered by solar energy
- Use of geothermal energy in areas with hot water springs
- Construction of wind energy farms in sea
- Research for cheaper and efficient material for solar cells and batteries
- Construction of dams to harvest kinetic energy of flowing water
- Research for alternative biofuels from the leftover husk of crops.
Hundreds of years ago, explorers often died of scurvy. This bone-related disease be prevented by C) supplementing the diet with fresh fruit rich in vitamin C. Vitamin C is essential for the production of collagen which is found in bones and connective tissue.
