For a cross in which the genotypes of the parents are  heterozygous, Rr, 25% of offspring will be unable to roll the tongue.

For a cross in which the genotypes of the parents are homozygous recesive rr, the offspring by 100% will be unable to roll the tongue. Probability 1

Tom [10]

Correct answer: C). Making sure that a piece of work is correct and includes bias

The peer review process can be defined as the process of exposing an author's research or ideas or results to be verified by the others who are expert in that field. Its main function is to encourage an author to meet the high standards of discipline in order to ensure that unacceptable results, interpretations or personal views are not published without the expert view.

Any scientific work should not contain any biasness as they may affect the validity of results. Hence, the scientific work does not have any bias.

Hence, the correct answer would be option C.

C. Read the hypotheses below, and identify the
tiny-mole [99]

Answer:

Independent variable: Salinity/Salt concentration

Dependent variable: hatching rate

Explanation:

As rightly stated in this question, INDEPENDENT VARIABLE, in an experiment, is the variable that the experimenter changes or manipulates in order to bring about a measurable response while the DEPENDENT VARIABLE is the variable that the experimenter measures in an experiment. Dependent variable as the name implies is dependent on the independent variable.

In this question where an hypothesis was given as follows: "Hatching brine shrimp is related to salinity (how salty the water is), then the greater the salt concentration, the higher the hatching rate". The hypothesis relates the independent and dependent variables i.e. it tells us how the independent variable affects the dependent variable.

Hence, according to the hypothesis, it is telling us how a change in SALINITY OR SALT CONCENTRATION will affect HATCHING RATE. Therefore;

Independent variable: SALINITY/SALT CONCENTRATION

Dependent variable: HATCHING RATE
