Answer:
In an experiment, the factor (also called an independent variable) is an explanatory variable manipulated by the experimenter. Each factor has two or more levels (i.e., different values of the factor). Combinations of factor levels are called treatments.
Explanation:
The table below shows independent variables, factors, levels, and treatments for a hypothetical experiment.
Vitamin C
0 mg 250 mg 500 mg
Vitamin
E 0 mg Treatment
1 Treatment
2 Treatment
3
400 mg Treatment
4 Treatment
5 Treatment
6
In this hypothetical experiment, the researcher is studying the possible effects of Vitamin C and Vitamin E on health. There are two factors - dosage of Vitamin C and dosage of Vitamin E. The Vitamin C factor has three levels - 0 mg per day, 250 mg per day, and 500 mg per day. The Vitamin E factor has 2 levels - 0 mg per day and 400 mg per day. The experiment has six treatments. Treatment 1 is 0 mg of E and 0 mg of C, Treatment 2 is 0 mg of E and 250 mg of C, and so on.
Answer:a layer of parallel elongated cells believe the epidermis of a leaf
Explanation:
Fungi obtain nutrients in three different ways: They decompose dead organic matter. A saprotroph is an organism that obtains its nutrients from non-living organic matter, usually dead and decaying plant or animal matter, by absorbing soluble organic compounds.
The answer that would best complete the given statement above is the term EVAPOTRANSPIRATION. As the plants grow high in the tree canopy and send out roots, these roots search for water vapor in the humid air, and this response that helps aerial plants find water is called evapotranspiration. Hope this helps.
<span>It helps because it slows the flow of the water down the slope and little by little the water will get soaked up and by the time it gets to the bottom. i think that is the correct answer
