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.
contour farming:
Contour farming has been practiced for centuries in parts of the world where irrigation farming is important. Although in the United States the technique was first practiced at the turn of the 19th century, straight-line planting in rows parallel to field boundaries and regardless of slopes long remained the prevalent method. Efforts by the U.S. Soil Conservation Service to promote contouring in the 1930s as an essential part of erosion control eventually led to its widespread adoption.

Answer:
Malonyl-CoA, a key intermediate in fatty acid synthesis, inhibits carnitine acyltransferase I, thereby blocking the entry of fatty acyl units into the mitochondrion for oxidation.
Fatty acyl-CoAs, the substrates for fatty acid oxidation, inhibit fatty acid synthesis by interfering with the polymerization of acetyl-CoA.
Hormonal effects on adipocytes are opposed; insulin promotes fatty acid synthesis by several mechanisms; while glucagon promotes fat breakdown and fatty acid oxidation
