What is the function of the cell membrane?
What is it controls what substances come into and out of a cell.
200
What is the purpose of DNA and where is it located in a cell?
What is it is used to direct all of the cells' functions and it is found in the nucleus.
300
Which structure directs all of the cell's activities?
A. vacuole B. nucleus C. ribosome D. cytoskeleton
300

In a microscope, an image is focused by
What is A) the eyepiece lens and the mirror B) the objective lens and the mirror C) the eyepiece lens and the objective lens D) the objective lens and a concave lens
300
Name three structures or organelles that are similar to both plants and animal cells.
What is cytoplasm, cell membrane, and mitochondria. You could have also said nucleus.
300
What is DNA?
What is the genetic material that carries information about an organism and that is passed from parent to offspring.
400
Which organelles convert energy in food molecules into energy the cell can use?
A. ribosomes B. vacuoles C. mitochondria D. golgi bodies
400
According to the cell theory,
What is A) cells come from nonliving things B) only plants are made of cells C) all cells come from other cells
400
What are the functions of these parts of the microscope? A) Stage clips B) Revolving nosepiece C) Stage D) Objective E) Arm F) Base
A) What is Holds the glass slide and specimen in place B) Switches between the different objective lens. C) Platform to support the slide D) Contains a lens capable of 10x magnification E) Holds the objectives above the stage F) Supports the whole microscope
400
What is the function of the nucleus?
What is it directs all of the cell's activities.
400
Why are nucleic acids important to all cells in the body?
What is they contain instructions that cells need to carry out all of the functions of life?
500
What is the cell theory?
What is all living things are composed of cells. Cells are the basic units of structure and function in living things. All cells are produced from other cells.
500
How do chloroplasts, mitochondria, and vacuoles work together in a plant cell?
Chloroplasts capture the sun's energy and use it to make food for the cell. Mitochondria convert energy in food to energy that the cell can use (ATP). Vacuoles store food and other materials the cell needs.
500
How did the invention of the light microscope help advance the study of life science?
What is the invention of the microscope made it possible to discover and learn about cells.
500
How does the nucleus "know" how to direct the cell?
What is thin strands of chromatin in the nucleus contain genetic material, the instructions for directing the cell's functions.
500
What do you notice about the nitrogen bases and how does this pairing determine how DNA replication occurs? What happens in DNA replication?
What is the same ones always pair. Adenine pairs with thymine, and guanine pairs with cytosine. The order of the bases in each new DNA molecule exactly matches the order of the bases in the original DNA molecule. The two strands in one molecule separate, and then new nitrogen bases pair up with each strand to form two molecules of DNA.
