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.

Answers

Answer:

The question is unclear, however, it can still be answered based on understanding of the topic, with correct explanation.

The independent variable is the HELICOPTERS MADE FROM DIFFERENT MATERIALS

Explanation:

The independent variable in an experiment is the variable that the experimenter manipulates or changes in order to effect a response in the dependent variable. The independent variable is also called the experimental variable.

In this case, Ben makes five paper helicopters using different materials and tests the amount of time each paper helicopter will take to fall. Hence, the PAPER HELICOPTERS MADE FROM DIFFERENT MATERIALS is the independent variable, which determines how long they will fly (dependent variable)

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.

Answers

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?

Answers

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.

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.
