What is a independent variable?
- A.
The Variable that is Expected to change.
- B.
The Variable in a experiment that is being tested.
- C.
The variable only used for comparison.
- D.
The procedure you are following to get the answer.
Correct Answer
B. The Variable in a experiment that is being tested.Explanation
An independent variable is the variable that is manipulated or changed by the researcher in an experiment. It is the variable that is being tested to see how it affects the dependent variable. In other words, it is the variable that the researcher has control over and can change to observe its impact on the outcome of the experiment.Rate this question:

What is a Hedotroph?
- A.
Organisms who CAN make their own houses/ shelters.
- B.
Organisms who CAN'T make their own houses/ shelters.
- C.
Organisms that CAN make their own food.
- D.
Organisms that CAN'T make their own food.
Correct Answer
D. Organisms that CAN'T make their own food.Explanation
A hedotroph is an organism that cannot make its own food. This means that it relies on obtaining nutrients and energy from external sources, such as consuming other organisms or organic matter. Unlike autotrophs, which can produce their own food through processes like photosynthesis, hedotrophs are heterotrophs that depend on external food sources for their survival.Rate this question:

What is the most abundant chemical in cells?
- A.
Water.
- B.
Carbohydrates.
- C.
Nucleic Acids.
- D.
Proteins.
Correct Answer
A. Water.Explanation
Water is the most abundant chemical in cells because it makes up approximately 70% of the total cell mass. It is essential for various cellular processes such as metabolism, transportation of nutrients, and maintaining cell structure. Water also serves as a solvent for many biological molecules, allowing them to interact and participate in biochemical reactions. Additionally, water helps maintain the proper pH balance and temperature within cells, ensuring optimal conditions for cellular functions.Rate this question:

True or False?The cells of organisms use energy for growth and repair.
- A.
True?
- B.
False?
Correct Answer
A. True?Explanation
The cells of organisms require energy for various processes, including growth and repair. This energy is obtained through cellular respiration, where glucose is broken down to release ATP, the energy currency of cells. This ATP is then utilized in processes like protein synthesis, cell division, and tissue repair. Therefore, it is true that cells use energy for growth and repair.Rate this question:

What is Control in A Scientific Experiment?
- A.
Items that remain the same in each trial.
- B.
One trial used for comparison.
Correct Answer
B. One trial used for comparison.Explanation
Control in a scientific experiment refers to a trial or group that is used as a reference point for comparison. It is a standard against which the experimental results are measured. By having a control group, researchers can determine the effect of the independent variable by comparing it to the control group, which remains unchanged. This allows for the identification of any changes or differences caused by the independent variable, providing a basis for drawing conclusions and making valid scientific claims.Rate this question:

The Variable That is expected to change because of the other variable is the __________ _____________.
Correct Answer
Dependent Variable.Explanation
The dependent variable is the variable that is expected to change because of the other variable. In an experiment, the dependent variable is the one that is measured or observed to determine the effect of the independent variable. It is called "dependent" because its value depends on the value of the independent variable. Therefore, the correct answer is the dependent variable.Rate this question:

The idea of living things can come from nonliving sources is...
Correct Answer
Spontaneous Generation.
Spontanues Generation.Explanation
The correct answer is "Spontaneous Generation." Spontaneous Generation is the idea that living organisms can arise from nonliving matter. This concept was widely believed in ancient times, but it was later disproven by experiments conducted by Louis Pasteur in the 19th century. These experiments showed that living organisms can only come from pre-existing living organisms, through processes such as reproduction or germination. Therefore, the idea of living things coming from nonliving sources is referred to as Spontaneous Generation.Rate this question:

Identify a problem or question, observe nature carefully, and make a predicition are What steps of the Scientific Method? Name them in ORDER.
Correct Answer
2, 1 and 3.
two, one, and three.Explanation
The correct order of steps in the Scientific Method is as follows: 1) Identify a problem or question, 2) Observe nature carefully, and 3) Make a prediction. This order ensures that scientists first identify a problem or question that they want to investigate, then carefully observe the natural world to gather data and information, and finally use this information to make a prediction or hypothesis about the problem or question.Rate this question:

Living things have homeostasis, (living internal conditions) because The _________ must be just right for it to __________ .
Correct Answer
Condition, function.Explanation
Living things have homeostasis because the condition, or internal environment, must be just right for the function, or proper functioning, of the organism. Homeostasis refers to the ability of an organism to maintain stable internal conditions despite changes in the external environment. This is crucial for the organism to carry out its various functions and processes effectively.Rate this question:

True or False?And unicellular cell is Many cells.
- A.
True?
- B.
False?
Correct Answer
B. False?Explanation
The correct answer is False. The statement "And unicellular cell is Many cells" is incorrect. Unicellular organisms are composed of a single cell, not multiple cells. They are capable of carrying out all necessary functions for survival within that single cell.Rate this question:

True or False? Most Cells can be seen only with a microscope.
- A.
True?
- B.
False?
Correct Answer
A. True?Explanation
Most cells can only be seen with a microscope because they are too small to be visible to the naked eye. Microscopes allow us to magnify the cells and observe their structures and functions in detail. While some larger cells, such as chicken eggs or human ova, can be seen without a microscope, the majority of cells, including those in plants, animals, and microorganisms, require the use of a microscope for observation. Therefore, the statement "Most cells can be seen only with a microscope" is true.Rate this question:
