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.

What are the three goals of integrated pest management (IPM)?
Delicious77 [7]

The correct answer is C. To reduce the use of artificial pesticides, reduce costs, and control pests.

Explanation

Integrated pest management (IPM) is a method that integrates different practices and scientific principles to make adequate management with pests. This method considers knowledge about the habits, life cycle, needs, and aversions of the pest, reducing the use of toxic methods and implementing less toxic methods, monitoring pest activity and adjusting methods over time, tolerating harmless pests, setting a threshold to decide when it is time to act, among others as its main principles. Therefore, the correct answer is C. To reduce the use of artificial pesticides, reduce costs, and control pests.

PLS HELP ASAP If an animal cell wasn't in an isotonic solution, wouldn't active transport be able to balance the cell's volume?
ohaa [14]

Answer:

Animal cells tend to do best in an isotonic environment, plant cells tend to do best in

a hypotonic environment. This is demonstrated in the attached PDF.

Explanation:

A cell that does not have a rigid cell wall, such as a red blood cell, will swell and lyse (burst)  when placed in a hypotonic solution, a process called cytolysis. Cells with a cell wall will swell when placed in a hypotonic solution, but once the cell is turgid (firm), the tough cell wall prevents any more water from entering the cell. When placed in a hypertonic solution, a cell without a cell wall will lose water to the environment, shrivel, and probably die. In a hypertonic solution, a cell with a cell wall will lose water too. The plasma membrane pulls away from the cell wall as it shrivels, a process called plasmolysis.

I hope this helps. If not I am really sorry!

Svetradugi [14.3K]

  • SS - spotted condition
  • 2 Ss - Spotted condition
  • ss - non-spotted condition

If two heterozygous Dalmatian dogs are crossed i.e. Ss × Ss, the allele combination for each gamete is as follows:

  • Ss - S and s
  • Ss - S and s

The following offsprings will be produced:

  • SS - spotted condition
  • 2 Ss - Spotted condition
  • ss - non-spotted condition
