Answer:
F. Is fatty acid molecule.
Explanation:
It's unsaturated fatty acid.
Fatty acid consists of a straight chain of an even number of carbon atoms, with hydrogen atoms along the length of the chain and at one end of the chain and a carboxyl group (―COOH) at the other end.
It is that carboxyl group that makes it an acid (carboxylic acid).

Then I will eat nothing but Special K cereal, milk and water for two weeks and track my weight in the morning. What do you think my hypothesis should be? What will my variables be? Hypothesis: Independent variable: Dependent Variable:
Answer:
Hypothesis: If you eat Special K cereal for 2 weeks, you will lose 10 pounds.
Independent variable: Special K cereal.
Dependent Variable: Weight lose.
Explanation:
Hypothesis: The term "hypothesis" is determined as a testable and a precise statement of what a specific researcher or experimenter predicts would be considers as the outcome of a particular study.
Independent variable: In research, the term "independent variable" is determined as a variable that is being re-organized in an experiment or research in order to see its impact on the dependent variable. Independent variable influences the dependent variable directly.
Dependent variable: The term "dependent variable" is determined as a variable that is being measured or tested in an experiment or research by the experimenter or researcher and is directly influenced by the independent variable.

Answer:
The mineral formed through evaporation.
Explanation:
Minerals are inorganic substances that occur naturally i.e. not man-made. These minerals are formed in different ways in nature. One of those ways is through EVAPORATION.
Since water dissolves a lot of substances including the particles of these minerals, the mineral components can be found in a dissolved state in water bodies e.g lakes, oceans etc. However, when heat increases and the water molecules evaporate (change to gas), the dissolved minerals in these water bodies crystallize out.
This is what happens when minerals form at the edge of a lake. The water from the lake evaporates leading to the formation of minerals.
Answer:
The mineral formed through evaporation.

Describe the stage of the cell cycle that takes place before mitosis.
The _____ stage occurs before mitosis. In this stage extra sub-______ structures are produced.
The interphase stage occurs before mitosis. In this stage, extra sub-phases like G1, S, and G2 are produced various proteins necessary for divisions.
What do you mean by Cell cycle?The Cell cycle may be defined as the process a cell goes through each time it divides.
Interphase is the initial stage of any cell cycle which is the interval between the end of one mitotic or meiotic division and the beginning of another. It is the longest phase of the cell cycle as compared to the mitotic phase.
Therefore, the interphase stage occurs before mitosis. In this stage, extra sub-phases like G1, S, and G2 are produced various proteins necessary for divisions.
