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.

It is an independent variable. Thus option A is correct.
What are the key difference between Independent and dependent Variable ?
The variable whose values are changed by researcher to get desired outcome is called an independent variable.
The variable, by changing its values to reciprocate change in the values of the independent variable is called the dependent variable.
The independent variable is act as the experiment controller whereas, the dependent variable act as experiment measure.
An independent variable is a cause whereas the dependent variable is an effect of that cause.
we can say in a linear regression, ‘y’ denotes dependent variable while ‘x’ denotes independent variable.
An independent variable does not rely on anything, while the dependent shows the effect, due to changes in independent variable.
Thus option A is correct.

what do you observe at low temperature medium temperature and high temperature
The temperature of a body can be related to the energy transferred between the particles of the body. Hence, temperature is directly proportional to the energy of the particles in the sample.
The kinetic energy possessed by the particles in a sample is highest at the highest temperature attained by the body. The kinetic energy drops as the temperature drop s from high to medium to low temperature. Hence, the low temperature samples have very low kinetic energy.Therefore, the energy possessed by the particles of a sample is directly proportional to the temperature of the sample.

Answer:Blood
Explanation:
Glucose reaches each and every cell through the circulation of blood, which is present in Option A as the primary function of the circulatory system, which includes the heart, blood vessels, and blood, is to transport essential nutrients.
What is blood?After food is digested and absorbed into the bloodstream, glucose is transported to cells throughout the body by the circulatory system, which consists of the blood, heart, capillaries, etc., where the heart pumps blood throughout the body via arteries, which branch into smaller vessels called arterioles and then into even smaller capillaries. The circulatory system also plays an important role in removing waste products, including carbon dioxide, from the body's tissues, so glucose has been used by cells for energy, the waste product, carbon dioxide, is transported back to the lungs, where it is exhaled.
Hence, glucose reaches each and every cell through the circulation of blood, which is present in Option A.

What is Fermentation?Fermentation is defined as a metabolic process that produces chemical changes in organic substrates through the action of enzymes which is narrowly defined as the extraction of energy from carbohydrates in the absence of oxygen.
Microorganisms such as bacteria and fungi have metabolic genes that allow them to produce enzymes to break down a variety of sugar metabolites.
Yeast and sugar produce carbonic gas through fermentation which is why as the yeast consumes the sugar, it produces alcohol (ethanol) and carbonic gas (carbon dioxide) as waste products, hence the carbon dioxide trapped in the dough lifts up,
Thus, the trapped carbon dioxide causes the dough to rise, evidence of a chemical change in Michael's bread-making process.

A car drives 150 m to the east then backtracks 30 m to the west. Describe the mathematical operation you will use to determine the net movement of the car.
Answer:
Subtraction operation
The car's displacement is 120 m west
Explanation:
Given;
first motion of the car as 150 m east
second motion of the car as 30 m west
The mathematical operation that will be used to determine the net movement of the car is subtraction operation.
The net movement of the car is the car's displacement.
Displacement is given by;
D = final position - initial position
D = 30 m - 150 m
D = - 120 m
The negative sign is direction = west ward direction
Thus, the car's displacement = 120 m west

Science rejects any hypothesis not supported by __________________________ and the results of ___________________________ experiments. what are the blanks?
Answer:
Observations; control.
Explanation:
A hypothesis is considered to be tentative or an educated guess and can be defined as a testable explanation for an observation or a scientific problem. An example of a hypothesis is saying, Corona virus is caused by the introduction of the "5G" technology.
On the other hand, a control experiment can be defined as an experiment in which a condition assumed to be a probable cause of the effect is being compared to the same situation by the scientist without involving or using the suspected condition.
Hence, science rejects any hypothesis not supported by observations and the results of control experiments.
This ultimately implies that, for any hypothesis to be acceptable in science, it must be supported by observations and the results of control experiments; this give rise to factual informations, theories and by extension solutions to problems.
