What is the difference between whole-chromosome aberrations and point mutations?

Biology
1 answer:
Lady_Fox [76]3 years ago
8 0
Both are types of mutation yet in a point change, one base combine is changed, and in a chromosomal deviation, a whole area of the chromosome is modified. 
A chromosome variation from the norm, issue, inconsistency, distortion, or change is a missing, additional, or unpredictable bit of chromosomal DNA. It can be from an atypical number of chromosomes or a basic anomaly in at least one chromosomes.

Which of the following best describes cell communication processes that are present in bacteria, yeast, and multicellular organi
Savatey [412]

Answer:

They release chemical messengers to communicate with cells they may or may not be in direct contact with.

Explanation:

Unicellular organisms such as bacteria or yeast, 'talk' to each other through the release of chemicals. In bacteria, this is known as quorum sensing which allows them to determine the surrounding bacterial population density. In yeast, one of the more popular pathways is known as the mating factor pathway, which allow the organisms to find mates. Whereas, in multicellular organisms (such as humans), this chemical release allows for cell-cell co-ordination which keeps the system functioning correctly.

chambers A and B are placed next to each other but are separated by a film permeable to both glucose and fructose. chambers A co
Molodets [167]

Answer:

2.glucose move into chamber B faster than fructose

Explanation:  

  • Facilitated diffusion: refers to the transport of hydrophilic molecules that are not able to freely cross the membrane. Channel protein and many carrier proteins are in charge of this <u>passive transport</u>. If uncharged molecules need to be carried <u>this process depends on concentration gradients</u> and molecules are transported from a higher concentration side to a lower concentration side. If ions need to be transported this process depends on an electrochemical gradient. The glucose is an example of a hydrophilic protein that gets into the cell by facilitated diffusion.  Facilitated diffusion is a passive transport process because the cell does not need any energy to make it happen.  

The exposed scenario is an example of facilitated diffusion, a process that occurs in favor of the concentration gradient, and which rate depends on the concentration of molecules in each side of the membrane, in this case, glucose and fructose, among other factors that might also influence the diffusion rate. So, as the concentration of glucose is higher in chamber A (80%), and lower in chamber B (20%), in comparison with fructose, the first one will diffuse faster than fructose. The difference in concentration between both chambers is sharper in glucose, so its transport is faster than the fructose transport, which will also diffuse but at a lower rate.
