Mrs. Jones's class conducted an experiment on the effects of sugar and artificial
sweetener on the cookies recipe's overall color when baked. What would be the
independent variable in the cookie experiment?
A. The students would use the same ingredients in both recipes, but bake the
cookies with sugar at 450 degrees and those with artificial sweetener at 475
degrees. They should increase the baking time on the artificial sweetener cookies,
since the package instructs them to do so.
B. The students should use the same. ingredients in both recipes, but increase the
baking time on the artificial sweetener cookies, since the package instructs them to
do so.
C. The students should use the same ingredients, same baking temperatures, and
same baking times for both recipes.
D. The students should use the same ingredients and making times in both recipes,
but bake the cookies with sugar at 450 degrees and the artificial sweetener cookies
at 475 degrees.
C.
The independent variable that is changed in the experiment in order to determine
its effect on the dependent variable or the outcome of the experiment.
- The dependent variable result from the experimenter making only one change to
an experiment that can be repeated with the same results.
,Which part of the cell is often called the cell "power house" because it provides
energy for cellular functions?
A. nucleus
B. cell membrane
C. mitochondria
D. cytoplasm
C. Mitochondria
Mitochondria are often called the power house fo the cell because they provide
energy for the cell to function.
- The nucleus is the control center for the cell.
- The cell membrane surrounds the cell and separates the cell from its
environments.
- Cytoplasm is the thick fluid within the cell membrane that surrounds the nucleus
and contains organelles.
What functions do ribosomes serve within the cell?
A. ribosomes are responsible for cell movement.
B. ribosomes aid in protein synthesis
C. ribosomes help protect the cell from its environment
D. ribosomes have enzymes that help with digestion
B. Ribosomes are organelles that help synthesize proteins within the cell.
- Cilia and flagella are responsible for cell movement.
- The cell membrane helps the cell maintain its shape and protects it from the
environment.
,- Lysosomes have digestive enzymes.
What is the most likely reason that cells differentiate?
A. Cells differentiate to avoid looking like all the cells around them.
B. Cells differentiate so that simple, non-specialized cells can become highly
specialized cells
C. Cells differentiate so that multicellular organs will remain the same size
D. Cells differentiate for no apparent reason.
B. Cells differentiate so that simple, less specialized cells can become highly
specialized cells.
How is meiosis similar to mitosis?
A. both produce daughter cells that are genetically identical
B. both produce daughter cells that are genetically different
C. both occur in humans, animals, and plants
D. both occur asexually
C. Both meiosis and mitosis occur in humans, animals, and plants.
- Mitosis produces cells that are genetically identical, and meiosis produces cells
that are genetically different.
- only mitosis occurs asexually
In the suburban neighborhood of Northwood, there have been large populations of
deer, and residents have complained about them eating flowers and garden plants.
, What would be a logical explanation, based on observations, for the large increase
int eh deer population one the last two season?
A. increased quantity of food sources in surrounding areas
B. Decreased population of a natural predator in Northwoods.
C. Deer migration from surrounding areas
D. Increase in hunting licenses sold.
C. Deer migration from surround areas
How do DNA an RNA function together as part of the human genome?
A. DNA carries genetic information form RNA to the cell cytoplasm.
B. RNA carries genetic information from DNA to the cell cytoplasm.
C. DNA and RNA carry genetic information form the cell nucleus to the cytoplasm
D. DNA and RNA do not interact within the cell.
B.
DNA is the primary carrier of genetic information in most cells.
- RNA serves as a messenger that transmits genetic information from DNA to the
cytoplasm off the cells.
The majority of nutrient absorption occurs in the:
A. mouth
B. stomach
C. small intestine
D. large intestine
