Easy!!
the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment.
Evaporation and transpiration since the suns energy causes this phenomenon
Carbon sequestration describes long-term storage of carbon dioxide or other forms of carbon to either mitigate or defer global warming and avoid dangerous climate change. It has been proposed as a way to slow the atmospheric and marine accumulation of greenhouse gases, which are released by burning fossil fuels.
I processes that transfer energy over Earth's surface are:
1) Conduction
2) Convection
3) Radiation
4) Latent Heat
Conduction is the transfer of heat from a warmer object to a cooler object through molecular interaction. As the Sun heats the ground, energy from the heated ground is transferred to the atmosphere by conduction.
Convection is the transfer of heat by mass movement of a fluid. Convection appears mostly in liquid and gases because they are free to move around. Heat is transferred upward and outward, away from the heat source, while cooler air is brought to replace the rising air.
Radiation is the final process of heat transfer. The energy received from the Sun, radiation, are absorbed by all objects that in turn radiates some of the energy back to its surroundings in a weaker form of energy called long wave radiation such as heat.
Later heat, also known as phase change, is the heat required to change phases. Example of phase change is water transforms from gas to liquid or solid or vice versa. For water to transform from liquid to gas, latent heat from the surrounding atmosphere is needed. In evaporation, water takes heat from the surrounding air in order to evaporated and become gas.
Answer:
Gene mutation:
Gene mutation may be defined as change or alteration in the nucleotide sequence of the gene. DNA replication errors and mutagens are responsible for the gene mutation. A single gene may affected in this mutation. For example: Sickle cell anemia is caused by the replacement of GAG to GUG results in the formation of valine instead of glutamic acid. The shape of RBCs changed from the biconcave to the sickle cell shape.
Chromosome mutation:
Chromosome mutation may be defined as the change or the alteration of chromosome number or structure. Chromosome mutation occurs due to errors during crossing over. The segment of the chromosome may get changed. Large number of genes may get affected. For example: Down syndrome occurs due to the presence of extra chromosome at chromosome 21.
