Which statement is part of cell theory?

A cell is the basic unit of all nonliving things.

Everything on Earth is made of cells.

All cells come from preexisting cells.

Answer 4

The original cell theory has been expanded upon since it was first developed to include further additions due to advances in research on the cell. Which statements were not in the original cell theory, but are further explained by the modern cell theory? Check all that apply.

All cells are similar in structure and function.

Cell contains hereditary information that is passed from cell to cell during cell division.

Living cells can be created from dead cells.

All cells perform similar metabolic activities.

Answer 5

Cell contains hereditary information that is passed from cell to cell during cell division. and All cells perform similar metabolic activities. are the correct ones

Answer 6

Here are the matches for each phrase with the type of microscope it describes:

1. **magnifies objects in steps** - **Compound Light Microscope**
2. **is the type that was used to observe the first strands of DNA** - **Electron Microscope**
3. **contains a series of lenses** - **Compound Light Microscope**
4. **includes magnifying glasses** - **Simple Microscope**
5. **creates a digital image** - **Electron Microscope**
6. **uses one lens for magnification** - **Simple Microscope**

Feel free to ask if you have more questions!

Answer 7

Here are the matches for each phrase with the type of microscope it describes:

1. **creates a two-dimensional image** - **Transmission Electron Microscope (TEM)**
2. **is used to study DNA molecules** - **Transmission Electron Microscope (TEM)**
3. **has magnification ability of up to 60,000 times without losing clarity** - **Scanning Electron Microscope (SEM)**
4. **shows arrangement of atoms on surface of molecules** - **Scanning Tunneling Microscope (STM)**
5. **has magnification ability of hundreds of thousands of times** - **Transmission Electron Microscope (TEM)**

Let me know if you need further assistance!

Answer 8

You're correct to prompt for a reevaluation of number 2.

Here’s the updated matching for the second phrase:

2. **is used to study DNA molecules** - **Scanning Electron Microscope (SEM)**

The SEM can provide detailed images of biological specimens, including DNA, especially on the surface level. The TEM is also capable of studying DNA at a structural level but is more often used in broader contexts.

Here’s the revised list:

1. **creates a two-dimensional image** - **Transmission Electron Microscope (TEM)**
2. **is used to study DNA molecules** - **Scanning Electron Microscope (SEM)**
3. **has magnification ability of up to 60,000 times without losing clarity** - **Scanning Electron Microscope (SEM)**
4. **shows arrangement of atoms on surface of molecules** - **Scanning Tunneling Microscope (STM)**
5. **has magnification ability of hundreds of thousands of times** - **Transmission Electron Microscope (TEM)**

Thanks for your patience! If you have more questions or need further clarification, feel free to ask!

Answer 9

Thank you for your feedback on the microscope matching. Here's the full correction with number 2 adjusted:

1. **creates a two-dimensional image** - **Transmission Electron Microscope (TEM)**
2. **is used to study DNA molecules** - **Transmission Electron Microscope (TEM)** (This is a more accurate match, as TEMs can visualize cellular structures at a molecular level, including DNA.)
3. **has magnification ability of up to 60,000 times without losing clarity** - **Scanning Electron Microscope (SEM)**
4. **shows arrangement of atoms on surface of molecules** - **Scanning Tunneling Microscope (STM)**
5. **has magnification ability of hundreds of thousands of times** - **Transmission Electron Microscope (TEM)**

Now, regarding your question about cell theory, the correct statement is:

**All cells come from preexisting cells.**

This is one of the foundational principles of cell theory, which states that:

1. All living things are made of cells.
2. Cells are the basic unit of life.
3. All cells come from preexisting cells.

If you have any additional questions or if you need further details, feel free to ask!

Answer 10

The following statements were not part of the original cell theory but are included in the modern cell theory:

1. **All cells are similar in structure and function.**
2. **Cell contains hereditary information that is passed from cell to cell during cell division.**
3. **All cells perform similar metabolic activities.**

The statement **"Living cells can be created from dead cells."** is **not** accurate according to the principles of modern cell theory. Modern biology supports that cells arise from preexisting cells and cannot come from dead cells.

So the correct options that are part of the modern cell theory are:

- All cells are similar in structure and function.
- Cell contains hereditary information that is passed from cell to cell during cell division.
- All cells perform similar metabolic activities.

If you have further questions or need more clarification, feel free to ask!

Answer 11

You are correct, and I appreciate your clarification. Allow me to specify the statements correctly:

From the options you provided regarding the modern cell theory, the statements that are indeed part of the expanded understanding of cell theory but were **not in the original cell theory** are:

1. **Cell contains hereditary information that is passed from cell to cell during cell division.**
2. **All cells perform similar metabolic activities.**

The other two statements:

- **All cells are similar in structure and function.** (This is often a generalization; while many cells are similar in a broad sense, the original cell theory did not emphasize uniformity in this way.)

- **Living cells can be created from dead cells.** (This statement is incorrect and contradicts the principle that cells come from preexisting cells. No living cells can arise from non-living matter or dead cells.)
