DNA binding proteins in prokaryotes regulate gene expression by controlling transcription
true or false​

Answers

Answer 1

Answer:

True

Explanation:

Gene expression, which involves the transcription of DNA into mRNA and the subsequent translation of mRNA into proteins, is regulated in the cell of prokaryotes i.e. it is kept under control. This regulatory process, however, is done at the TRANSCRIPTIONAL LEVEL, in prokaryotic organisms like bacteria.

DNA binding proteins called transcription factors bind to the promoter region of a gene and either facilitates/enhance the binding of RNA polymerase or inhibits its binding. The enhancers are called ACTIVATORS while the inhibitors are called REPRESSORS.

If i added 27 grams of salt to water and saparated the solution with a hot plate what amount of salt will be left behind

Answers

Answer:

27 grams

Explanation:

27 grams of salt would still be left behind.

The dissolution of salt in water is a physical reaction and the salt can be recovered by evaporating off the water using appropriate procedures.

Provided that no part of the salt/water mixture is lost during the process of evaporation, if 27 grams of salt was dissolved initially, the same amount of salt would be recovered at the end of the separation process.

what kind of authority does our elected government officials exercise?​

Answers

Answer:

Depending upon the country and community in which you live, the authority exercised by elected officials is defined by formal rules and informal norms of behavior that apply in that jurisdiction. Authority is the willing compliance, almost automatic, with dictates from figures to whom we grant that authority. The formal rules limiting government officials’ authority should protect citizens from abuses of that authority but informal norms may sometimes allow elected officials to get away with actions that violate those rules or, at least, bend them to their own purposes.

Rational- legal authority is practiced by elected government officials. The

practice of the people voting the officials they deem fit is referred to as

Democracy.

Democracy involves leadership of the people through laws which govern

that area. The laws  are referred to as constitution and contains the power

and authority that government officials and says what can be done by them

or not with laid down consequences if disobeyed.

This however helps to put office holders in check as no one is above the

law in order to prevent anarchy.

Why are genetic variation and selective breeding are advantages of sexual reproduction?

Answers

The evolution of sexual reproduction is a great puzzle in modern evolutionary biology. Many groups of eukaryotic organisms, especially most animals and plants, reproduce sexually. The evolution of sex between two organisms of the same species contains two related but different themes: its origin and its maintenance. However, since hypotheses for the origin of sex are difficult to test experimentally, most of the current work has focused on the maintenance of sexual reproduction. Biologists, including W. D. Hamilton, Alexei Kondrashov, and George C. Williams, have proposed various explanations for how sexual reproduction is maintained in a large set of different living things.

A scientist with the EPA examining water for contamination writes down that there was an iridescent sheen on the surface of the water. What type of data did the scientist record

Answers

Answer: Qualitative data

Explanation:

Since we are informed that the scientist writes down that there was an iridescent sheen on the surface of the water, this is a qualitative data.

Qualitative data is a firm of data that one can observe and then record. It should also be noted that it is non numerical. It can be gotten from observations, conducting focus groups, having a one-to-one interviews, etc.

Answer: this is qualitative and categorical (binary) data

Explanation:

There are no measurements. The observation is qualitative: observation of some change in appearance. It is categorical in that the possible values are only ‘no sheen’ or ’sheen’.
