What is the difference between control group and controlled variables of an experiment

Biology
1 answer:
Likurg_2 [28]2 years ago
4 0

Answer:

Control group is a set of experimental samples or subjects that are kept separate and aren't exposed to the independent variable. A controlled experiment is one in which every parameter is held constant except for the experimental (independent) variable.

How might an RNA-based genome result in an increased infection rate? What are some potential complications to this infection str
WITCHER [35]

Answer:

I think the question is "How might an RNA-based genome results display an increased in infection rate?" because current statement doesn't convey a message clearly.

Explanation:

To answer this question, we need to understand first that what is gene expression. Gene expression is a process in which genetic information is transcribed first to RNA and then into proteins. During transcription stage, only active genes would be transcribed to RNA and all other DNA material don't transcribe at all. Now, if there is an infection, host cell would express only those genes which would actively take part in the defense mechanism, e.g. R-genes, genes involved in production of reactive oxygen species, etc. Hence, to monitor the infection rate, we will look at the RNA-based genome. To do this, we will extract the total RNA and then would sequence it. Then we will annotate the genes and check the relative abundance (differential expression). Finally, we would have a clear that these genes were active against the infection. By doing temporal sampling and sequencing, we would be able to measure the rate as well.

For the second part, potential complications that could arise in doing analysis is the lower amount of RNA, or rapid degradation of RNA in case of presence of RNAses. RNA can be degraded easily at room temperature.

Mumz [18]

Answer:

C is the Answer.

Explanation:

Carbon is an organic element which when broken down will release energy within an organism.  

Process of elimination

A: Wrong because Water has nothing to do with carbon being broken down.

B: Wrong because when carbon is broken down no waste products are being eliminated.

C: Right because Energy is released when Carbon is broken down

D: Wrong because Carbon being broken down has nothing to do with oxygen being absorbed.
