What must be present for the araC gene to be activated?

Answers

The araC gene is associated with the arabinose operon in bacteria, such as E. coli. For the araC gene to be activated, the presence of arabinose is crucial. AraC is a regulatory protein that can act as both an activator and a repressor, depending on the presence or absence of arabinose.

In the absence of arabinose, AraC represses the ara operon. When arabinose is present, it binds to AraC, causing a conformational change in the protein. This altered form of AraC then acts as an activator, promoting the transcription of genes in the ara operon.

So, in summary, arabinose is the key inducer required to activate the araC gene and initiate the expression of genes in the arabinose operon.

Within this population, there is a different frequency of alleles than there is throughout the population of southern Germany and Switzerland from which they came. Given this information, how is it possible that polydactyly, or the condition where people have extra fingers and toes, is more common within this group? Please choose the correct answer from the following choices, and then select the submit answer button.

Answers

Answer:

Polydactyly is a genetic condition where formation of extra finger or toe takes place.The extra finger or toe is called as supernumerary.

Explanation:

Polydactyly is associated with mutation in genes in their cis position Mutation in Hoxa gene also results in polydactyly.

It is associated with autosomal dominant mutation that occur in single gene.

This condition appears 1 in every 500.This is a common disorder in African black children and is more frequently found in Africans that are living in Eastern and central part.

Polydactyly is mainly affects the right toe or finger.

It is common in men.

The extra digit may be functional or not,partly formed with some bone.

Which statement best explains why water is known as the universal solvent?

Answers

It is known as a universal solvent because of the vast number of compounds that dissolve in water completely. This however goes for destilated water which has been cleansed from all waste and the water has been purified to be pure H2O. This means there's no metals or trace compounds inside.

Which of the following statements about tolerance range is true?a.

Tolerance range is different for different organisms.


b.

The tolerance range is the total number of organisms that can be supported by an ecosystem.


c.

Tolerance range is affected by biotic factors in an ecosystem.


d.

The available water supply does not impact an organism’s tolerance range.

Answers

The answer is a. Tolerance range is different for different organisms. 

Tolerance range is range of abiotic factors that must be maintained in order for species or populations to survive and function normally. Tolerance range is different for different organisms. It is affected by abiotic factors in an ecosystem. These abiotic factors could be available water supply, temperature, climate, etc.

Choice b could not be the right answer because  the total number of organisms that can be supported by an ecosystem is known as carrying capacity.

The Possible answer would be A.
