What tool do you use to view the cells?
- A.
Metric ruler
- B.
Centrifuge
- C.
Microscope
- D.
Pipette
Correct Answer
C. MicroscopeExplanation
A microscope is used to view cells because it allows for magnification and visualization of cells at a microscopic level. It enables scientists to observe the structure, shape, and characteristics of cells, which are otherwise not visible to the naked eye. By using a microscope, scientists can study the intricate details of cells and gain a better understanding of their functions and behavior.Rate this question:

What of the following is not a cell theory
- A.
All non living things have cell
- B.
Cell is a building unit of life
- C.
Cells make tissues
- D.
Nucleus is important part of the cell
Correct Answer
A. All non living things have cellExplanation
The statement "All non living things have cell" is not a part of the cell theory. The cell theory states that all living organisms are composed of cells, cells are the basic unit of structure and function in living organisms, and all cells come from pre-existing cells. The statement that all non-living things have cells is incorrect because non-living things do not possess the characteristics of living organisms and therefore do not have cells.Rate this question:

Which is the correct order of the organization?
- A.
Tissue, cell, organ, organ system
- B.
Organ, organ system, tissue, organism, cells
- C.
Cells, tissue, organ, organ system, organism
- D.
Cells, organs, tissue, organ system, organism
Correct Answer
C. Cells, tissue, organ, organ system, organismExplanation
The correct order of organization is cells, tissue, organ, organ system, organism. This is because cells are the basic building blocks of living organisms. Cells combine to form tissues, which are groups of similar cells that perform a specific function. Different types of tissues come together to form organs, which are structures that carry out specific functions in the body. Organs work together in organ systems, which are groups of organs that work together to perform a specific function. Finally, all the organ systems together make up an organism, which is a living being.Rate this question:

A group of similar cells that come together to perform a specific function is a/an
- A.
Organ
- B.
Tissue
- C.
Organism
- D.
Organ system
Correct Answer
B. TissueExplanation
A group of similar cells that come together to perform a specific function is called a tissue. Tissues are the building blocks of organs and organ systems, allowing for specialized functions such as muscle contraction, nerve transmission, or nutrient absorption. This cellular organization is crucial for maintaining the structure and function of living organisms, enabling complex biological processes to occur efficiently.Rate this question:

This is the example of _____
- A.
Organ
- B.
Organ system
- C.
Tissue
- D.
Cell
Correct Answer
B. Organ systemExplanation
This question is asking for an example of something. The options given are organ, organ system, tissue, and cell. The correct answer is "organ system." An organ system is a group of organs that work together to perform a specific function in the body. This is different from an individual organ, which is a structure made up of different tissues that performs a specific function. A tissue is a group of cells that work together to perform a specific function, and a cell is the basic unit of life. Therefore, the correct answer is organ system.Rate this question:

This is the example of _____
- A.
Organ
- B.
Organ system
- C.
Tissue
- D.
Cell
Correct Answer
A. OrganExplanation
This question is an example of a classification question where the options are different levels of biological organization. The correct answer, "Organ," represents a higher level of organization compared to the other options. An organ is a group of tissues that work together to perform a specific function in the body.Rate this question:

Tissues that perform the same function is called ____
- A.
Cells
- B.
Tissue
- C.
Organ
- D.
Organ system
Correct Answer
C. OrganExplanation
An organ is composed of different types of tissues that work together to perform a specific function in the body. For example, the heart is an organ composed of cardiac muscle tissue, connective tissue, and nervous tissue, among others, all working together to pump blood throughout the body.Rate this question:

- 8.
A group of tissues that perform similar function is called _____ (Examples included heart, lungs or stomach)
- A.
Organ
- B.
Organ system
- C.
Tissue
- D.
None of the above
Correct Answer
A. OrganExplanation
The correct answer is "Organ". This is because a group of tissues that perform similar functions is called an organ. Examples of organs include the heart, lungs, and stomach.Rate this question:

Correct Answer
B. TissueExplanation
This question is an example of a classification question. The options provided are different levels of biological organization, ranging from cells to organisms. The correct answer is "Tissue" because it is the level of organization that is higher than cells but lower than organs. Tissues are groups of cells that work together to perform a specific function in the body.Rate this question:

What is the difference between a cell and a tissue?
- A.
Cell is basic unit of life; tissue is a group of different cells
- B.
Cell is a basic unit of life; tissue is a group of cells that work as one
- C.
Cell is a basic unit of life; tissue is group of different organs
- D.
None of the above
Correct Answer
A. Cell is basic unit of life; tissue is a group of different cellsExplanation
A cell is the basic unit of life, meaning it is the smallest and most fundamental unit that can carry out all the necessary functions of life. On the other hand, a tissue is a group of different cells that work together as one unit to perform a specific function. Therefore, the correct answer is that a cell is the basic unit of life, while a tissue is a group of cells that work as one.Rate this question:

When many organs system works together it can form_____
- A.
Organs
- B.
Organ system
- C.
Tissue
- D.
Organism
Correct Answer
D. OrganismExplanation
When multiple organ systems work together, they form an organism. An organism is a complete living entity, made up of various organ systems, such as the respiratory, digestive, and circulatory systems, which collaborate to perform the functions necessary for life. The other options represent smaller components of this hierarchy:
Organs are individual structures made up of tissues that perform specific functions.
Organ systems are groups of organs working together to perform complex functions.
Tissues are groups of similar cells that work together to perform a specific job.
Thus, multiple organ systems combine to form an organism.Rate this question:

Which one of these is the basic unit of life
- A.
Organs
- B.
Organism
- C.
Tissue
- D.
Cell
Correct Answer
D. CellExplanation
The basic unit of life is a cell. Cells are the smallest structural and functional unit of living organisms. They are responsible for carrying out all the necessary processes of life, such as metabolism, growth, and reproduction. Cells can exist as independent organisms, such as bacteria, or they can work together to form tissues, organs, and ultimately, an organism. Therefore, out of the given options, the correct answer is cell.Rate this question:

Controls what passes in and out of the nucleus
- A.
Nuclear membrane
- B.
Vacuole
- C.
Cytoplasm
- D.
Chloroplast
Correct Answer
A. Nuclear membraneExplanation
The nuclear membrane is responsible for controlling what passes in and out of the nucleus. It acts as a barrier, separating the contents of the nucleus from the cytoplasm. This selective barrier allows certain molecules to enter or exit the nucleus while preventing others from doing so. The nuclear membrane is composed of two layers, an inner and outer membrane, which are perforated by nuclear pores. These pores regulate the transport of molecules, such as proteins and RNA, between the nucleus and the cytoplasm. Therefore, the nuclear membrane is the correct answer as it controls the movement of substances in and out of the nucleus.Rate this question:
