Answer:
The action and reaction forces are reciprocal (opposite) on an object. The swimmer pushes against the water (action force), the water pushes back on the swimmer (reaction force) and pushes her forward. The ball puts a force on the wall (action force), and the wall puts a force on the ball (reaction force) so the ball bounces off.
Explanation:
Well, they are both deposited by glaciers, but the way they are deposited makes them different. Till is just sediment left by the ice, outwash is deposited by the running water coming off of the glacier. Your welcome! Don't for got to thank me!
Answer:
<u>Changes in inheritable physical or behavioural traits</u> due to changes caused by variations as the organism move from one generation to another.
In addition changes in selective pressures of their new environments in order to gain adaptions for survival in the new environment is another factor for this changes.
Explanation:
Answer:
Phosphorylation
Methylation
Explanation:
Histone mobilization deals with the covalent bonding of several functional groups to the free nitrogens in the R-groups of lysine in the N-terminal tail.
DNA transcription can be controlled or altered via 'methylation' on the histones. Methylation is the mode of transferring methyl group to amino group of histone proteins that form the nucleosomes, which result to chromosomes formation through wrapping of DNA double helix around it. Histones methylation can either increase or decrease genes transcription. Chromatin modification is known to stimulate neural pathways that are essential for long memories and learning.
Histones phosphorylation is associated transcriptional activation. It deals with the transfer of phosphate group to amino acids of the proteins. Phosphate group known to be negatively charged, when transferred to amino acids of the histone proteins, it creates a repulsive force with the negatively charged phosphates of the DNA backbone. It can occur in serine, tyrosine and threonine. The enzymes kinases activate phosphorylation, while protein phosphatases remove phosphate groups.
