<span>Cell cycle checkpoints are control mechanisms necessary for proper cell division. In the cell cycle, there are two checkpoints: the G1 checkpoint and the G2 checkpoint. The G1 checkpoint is right before the S phase, and G2 checkpoint is right before the M phase.
</span><span>The G2 checkpoint is a DNA damage checkpoint and if DNA is damaged, entering the cell cycle is delayed before mitosis (M phase).</span><span>

The thing that is happening when you gargle with salt water is you are creating a high-salt barrier. As a result fluids are pulled out from the tissues in the throat area and the viruses are washed out. Fluids (water) are moving down the concentration gradient (to the area with the high salt concentration) and this is an example of passive transport.
Answer:
The founder effect may result in a population with a diminished gene pool, so there is a need to choose organisms with diverse genetic material.
In order to reduce the loss of any allele, preferential mating must be made between the organisms possessing rare alleles.
Inbreeding leads to reduced fitness as inbreeding occurs because of mating between the associated individuals, thus, there is a need to permit the least associated individuals to mate.
The captive-bred animals may exhibit reduced adaptation in wild, thus, they must be discharged into the wild prior passing of the generation.
The loss of learned behavior is generally associated with the acquired trait and does not associate much with genetics.
When the fossil fuels are burned they produce energy and give of harmful gas
Answer:
To form a strand of DNA, nucleotides are linked into chains, with the phosphate and sugar groups alternating. ... DNA is made of chemical building blocks called nucleotides. These building blocks are made of three parts: a phosphate group, a sugar group and one of four types of nitrogen bases.
Explanation:
