The three sources of energy include,

Solar energy

Wind energy

Water and geothermal.


Energy is termed as the capacity of physical system to do work. It exists as kinetic or mechanical energy, light potential energy, electrical and heat.

Source of energy can be classified as renewable and non-renewable.

The renewable is derived from natural processes which replenished constantly, for example, solar energy, biomass, ocean, hydropower and wind.

The solar energy it is sustainable to mean that it does not run out but it is maintained reason being that sun shines every day.

A good advantage of solar is that it is natural and available in plenty, and non-pollution. Wind energy helps to turn the blades of windmills as it turns shaft to where they are attached.

Cas9 cleaves both strands of the target DNA. Which of the following could occur when cells will try to repair the damage after c
Aloiza [94]

The correct answers are: the insertion of a DNA sequence into the targeted gene and deletions of the targeted gene

Cas9 is an enzyme endonuclease (which means it cuts nucleotides) that is part of the CRISPR-Cas9 complex- genome editing tool that can remove, add or alter sections of the DNA sequence.

Cas9 recognize the sequence that is going to be cut thanks to guide RNA- pre-designed RNA sequence complementary to sequence of interest. DNA repair machinery will try to fix the “damage” but it can add (insert) or delete some nucleotides.

A. Which form of nitrogen in the soil is NOT usable by organisms?
Colt1911 [192]

Answer:

A)Fixation. Nitrogen in its gaseous form (N2) can't be used by most living things

B) it can not be used because it most be converted or, ’fixed’  to a more useable form. To do this it goes through a process called fixation.fixation is the change in a gene pool from a situation where there exists at least two variants of a particular gene (allele) in a given population to a situation where only one of the alleles remains.

C) This form can be made more usable if it’s converted. It has to go through the process of fixation so the gene pool changes.
