Answer:
In a research there are two variables independent and dependent variable. independent variable is defined as the variable which is controlled and changed in a scientific experiment and evaluate the effects on the dependent variable while the variable which are tested and measured in experiment are called dependent variable.
When antibiotic is sprayed at one side of the petri dish, the bacterial growth on that side will eventually decrease in comparison to other side.
So, the independent variable in this experiment will be antibiotic because it is used to understand the growth of bacteria by decreasing their numbers and the dependent variable in this experiment will be bacteria as they vary according to the change in independent variable that is antibiotic.
The bacteria is the dependent variable whose growth is dependent on the antibiotic presence or absence, while the antibiotic is the independent variable.
An Independent variable is a variable whose value is never dependent on another variable other than the researcher. A dependent variable is a variable whose value is dependent on another variable.
An independent variable is the expected cause. A dependent variable is the expected effect.
The side of the petri dish which is sprayed with an antibiotic will have a decreased bacterial growth as compared to the other side of the petri dish.
In this case, the antibiotic affects the bacterial growth and is called an independent variable which is not affected but the bacteria is a dependent variable as its growth is affected by the antibiotic.

Answer and Explanation:
Answer:
there are three different species.
Explanation:
There are three different species of monkey according to the hypothesis because all monkey species have different feeds i. e. one feed on the fruits while the other feed on the tree sap. It also shows that two monkey species have same feed i. e. eating fruits while one specie feeds on tree sap. This hypothesis also shows that no specie of monkey feeds on leaves and insects present on the trees.
offspring will be white flowered?
Answer:
100%
Explanation:
This question involves a single gene coding for flower color in pea plants. The allele for purple flowers (P) are dominant to white flowers (p). This means that purple color will be expressed in a heterozygous state.
According to this question, If two white flowered plants are cross i.e. pp × pp, the following gametes will be produced by each of the parent: p and p. Using these gametes in a punnet square (see attached image), ALL (100%) of the offsprings will be white colored (pp).
Therefore, 100% of the offsprings will be white flowered.
b. cytomegalovirus
c. norovirus
d. poliovirus
