Albert, a student researcher, varies the amount of food given to rats in an experiment to measure the effect on their learning behavior. In albert's study, the amount of food given is the independent variable.

An independent variable is under the control of the experimenter. Independent variable does not depend on the other variables involved in the experiment. Since the amount of food is varied, it is not depending on other variables like size of mice, weight, etc.

Essay Frankenstein predictions
atroni [7]

Answer:

The monster in Mary Shelly’s Frankenstein lurches into life as big as a man but as ignorant as a newborn. He can’t read, speak, or understand the rudiments of human interaction. When he stumbles upon the cottagers, however, he picks up language by observing them and studying their speech. It is this acquisition of language, along with the eloquence it brings, that turns the monster from a mysterious nightmare into a sympathetic and tragic figure. By showing how language transforms the monster, and by contrasting the well-spoken monster with his equally articulate creator, Shelley argues that verbal communication—rather than action or appearance—is the only way through which people can truly understand one another.

bogdanovich [222]

If mutation destroys the function of the Cas9 gene then the bacteria will not be able to target a specific bacteriophage for destruction upon infection for the second time.

<h3>What is the Cas9 gene?</h3>
  • Cas9 is a 160 kilodalton protein that plays a vital role in the immunological defense of certain bacteria against DNA viruses and plasmids and is heavily utilized in genetic engineering applications.
  • Its main function is to cut DNA and thereby alter a cell's genome.
  • Although Cas9 is an endonuclease and is evolved as a mechanism of immunity against viruses, they are not considered restriction enzymes.

If the mrna is damaged, it directly interferes with the ability of a animal cell to do which of the following?
Elena-2011 [213]

Answer:

Proteins.

Explanation:

If the mRNA is damaged, it directly interferes with the ability of producing proteins in animal cell because mRNA is responsible for carrying the protein blueprint from a cell's DNA to its ribosomes which are considered as the machines of the cell that produces proteins for the cell. These messenger RNA has the information about what type of proteins are required to produced for the cell. So if mRNA is damaged, the ribosomes are unable to produce proteins for the cell.
