(Entry 1 of 2) transitive verb.

1a : to exercise restraining or directing influence over : regulate control one’s anger.

b : to have power over : rule A single company controls the industry..

Which axis indirectly shows the relative amount of DNA per cell by what relationship?

x-axisWhich axis indirectly shows the relative amount of DNA per cell? By what relationship? the x-axis; the DNA was stained, so there is a positive correlation between fluorescence and DNA content.

Which of the following is a function of the S phase in the cell cycle?

Which of the following is a function of the S phase in the cell cycle? The synthesis of sister chromatids, DNA replication occurs during S phase and results in two sister chromatids for each original chromosome. … Chromosomes must undergo replication before mitosis can occur; this copying occurs during the S phase.

What are some examples of control?

Control is defined as to command, restrain, or manage. An example of control is telling your dog to sit. An example of control is keeping your dog on a leash. An example of control is managing all the coordination of a party.

How does a control group work?

The control group (sometimes called a comparison group) is used in an experiment as a way to ensure that your experiment actually works. It’s a way to make sure that the treatment you are giving is causing the experimental results, and not something outside the experiment.

How do you identify a control?

If you have not identified the control in a science experiment, you may be mistaking one of your controls as an independent variable. Remember that the control should never change. If your independent variable always remains the same, odds are it is your control.

What is a control group easy definition?

Control group, the standard to which comparisons are made in an experiment. … A typical use of a control group is in an experiment in which the effect of a treatment is unknown and comparisons between the control group and the experimental group are used to measure the effect of the treatment.

What is a control in biology?

In scientific experiments, a scientific control is one in which the subject or a group would not be tested for the dependent variable(s). The inclusion of a control in an experiment is crucial for generating conclusions from the empirical data. … The use of controls allows to study one variable or factor at a time.

Why is a control group important?

You would compare the results from the experimental group with the results of the control group to see what happens when you change the variable you want to examine. A control group is an essential part of an experiment because it allows you to eliminate and isolate these variables.

What is the importance of S phase?

The S phase of a cell cycle occurs during interphase, before mitosis or meiosis, and is responsible for the synthesis or replication of DNA. In this way, the genetic material of a cell is doubled before it enters mitosis or meiosis, allowing there to be enough DNA to be split into daughter cells.

What is the purpose of a control group?

In a scientific study, a control group is used to establish a cause-and-effect relationship by isolating the effect of an independent variable. Researchers change the independent variable in the treatment group and keep it constant in the control group. Then they compare the results of these groups.

What is S phase of cell cycle?

In the eukaryotic cell cycle, chromosome duplication occurs during “S phase” (the phase of DNA synthesis) and chromosome segregation occurs during “M phase” (the mitosis phase).

What is control in an experiment?

A scientific control is an experiment or observation designed to minimize the effects of variables other than the independent variable. This increases the reliability of the results, often through a comparison between control measurements and the other measurements.

What is control condition example?

For example, if researchers were to design an experimental study to test the effect of loud music on test performance, students who did not listen to loud music would be in the control group. … Not all experimental designs have a control condition.

What is the purpose of a control experiment?

Scientists use controlled experiments because they allow for precise control of extraneous and independent variables. This allows a cause and effect relationship to be established. Controlled experiments also follow a standardised step by step procedure. This makes it easy another researcher to replicate the study.

What is the purpose of control variables?

Controlling variables is an important part of experimental design. Controlled variables refer to variables or contributing factors that are fixed or eliminated in order to clearly identify the relationship between an independent variable and a dependent variable.

What occurs in g2 phase?

Gap 2 (G2): During the gap between DNA synthesis and mitosis, the cell will continue to grow and produce new proteins. At the end of this gap is another control checkpoint (G2 Checkpoint) to determine if the cell can now proceed to enter M (mitosis) and divide. … Cancer cells reproduce relatively quickly in culture.

How do you describe a control group?

The control group is defined as the group in an experiment or study that does not receive treatment by the researchers and is then used as a benchmark to measure how the other tested subjects do.
