Cell Differentiation And Homeostasis
It’s time to put your thinking caps on and see if your biology knowledge is up to scratch. In this quiz we’ll be talking all about homeostasis – the state of steady internal conditions maintained by living things – as well as cell differentiation. Think you can tell us about these topics? Let’s find out!
- 1.
What term goes in the box labeled C?
- A.
Mature Cell
- B.
Self Renewal
- C.
Differentiation
- D.
Stem Cell
Correct Answer
C. DifferentiationExplanation
The term that goes in the box labeled C is "Differentiation." Differentiation refers to the process by which a stem cell transforms into a specialized cell with a specific function. It involves the activation and repression of specific genes, leading to the development of distinct cell types in the body. This process is crucial for the growth, development, and maintenance of tissues and organs in multicellular organisms.Rate this question:

What is the definition of cell differentiation?
- A.
Process by which a less specialized cell becomes a more specialized cell part
- B.
Cells that are able to differentiate (change) into different cell parts
- C.
When the whole cell is fully developed
- D.
Process by which stem cells divide to make more stem cells
Correct Answer
A. Process by which a less specialized cell becomes a more specialized cell partExplanation
Cell differentiation refers to the process in which a less specialized cell undergoes changes and becomes a more specialized cell part. This process involves the activation and repression of specific genes, leading to the development of distinct cell types with specialized functions. Through differentiation, cells acquire unique characteristics and structures that enable them to perform specific roles within the organism. This process is essential for the growth, development, and maintenance of multicellular organisms.Rate this question:

All body cells in your body have the same DNA
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Remember, they all started from the same cell so they all have the same DNA!Rate this question:

What is the correct order of organization in order of increasing complexity (from smallest to largest)?
- A.
Cell -> organ system -> organ -> tissue -> organelle
- B.
Organelle -> cell -> tissue -> organ -> organ system
- C.
Organ system -> organ -> tissue -> cell -> organelle
- D.
Cell -> organ -> tissue -> organelle -> organ system
Correct Answer
B. Organelle -> cell -> tissue -> organ -> organ systemExplanation
The correct order of organization in increasing complexity is organelle -> cell -> tissue -> organ -> organ system. This is because organelles are the smallest units of a cell, cells are the basic building blocks of living organisms, tissues are groups of cells that work together to perform a specific function, organs are made up of different tissues and perform specialized functions, and organ systems are groups of organs that work together to carry out specific functions in the body.Rate this question:

When your body temperature increases from stress or exercise, what is one of the most predominant actions that your body does to keep homeostasis and how does it keep homeostasis?
- A.
Shivering to keep making your body more warm
- B.
Chills to make you put on a blanket to stay warm
- C.
Sweating to bring your body temperature back down to normal
- D.
Fever to make you feel even more hot
Correct Answer
C. Sweating to bring your body temperature back down to normalExplanation
When the body temperature increases due to stress or exercise, sweating is one of the most predominant actions that the body does to keep homeostasis. Sweating helps to bring the body temperature back down to normal by evaporating the moisture on the skin, which cools the body. This process helps to regulate the body temperature and maintain a stable internal environment.Rate this question:

Why do all body cells in the body have the same DNA?
- A.
They all serve the same function
- B.
They all express (turn on) the same genes
- C.
They all have the same shape
- D.
They all started from the same cell (zygote stem cell)
Correct Answer
D. They all started from the same cell (zygote stem cell)Explanation
All body cells in the body have the same DNA because they all started from the same cell, which is the zygote stem cell. During embryonic development, the zygote divides and gives rise to all the different types of cells in the body. Each cell contains the same DNA as the zygote, which is passed down from one cell division to the next. As the cells differentiate and specialize into different tissues and organs, they express different genes and perform different functions, but their DNA remains the same.Rate this question:
