Introduction to Biology and Scientific Method

The Scientific Method always has an equal number of experimental groups compared to the control group

The Scientific Method is used to develop new products and technologies.

A hypothesis is a statement that is always correct and proven by the experiment.

A valid experiment should test only one variable at a time

The Scientific Method can be used to answer any question.

The hypothesis should be a simple statement that describes the desired outcome.

The Scientific Method is just a guideline, and not all steps have to be followed in the same order.

Science is only about collecting and explaining information, not testing that explanation.

A valid experiment will always result in the same conclusion, regardless of the variables changed.

The independent variable is the variable that is measured in an experiment.

To determine if grass grows better in soil than gravel, the dependent variable would be the soil type.

Evolution is considered a theory because it is a well-supported explanation for how life has changed over time.

The most important rule in any laboratory is wearing safety glasses.

All living organisms have exactly 6 characteristics.

A fire blanket is used to extinguish flames by cooling the burning material.

A broken glass container is used to protect custodial staff from broken glass in garbage.

All living things reproduce sexually to ensure the survival of their species.

The study of cells is called cytology.

The term abiotic refers to something that is made up of living things.

Protozoa are known as first animals.

The term dermatitis refers to inflammation of the bones.

The term anaerobic describes something that requires oxygen to survive.

The term bilateral describes an organism that has one side.

The term arthropod refers to an organism that has segmented feet.

All living organisms obtain energy by producing their own food through photosynthesis.

The process of releasing waste products from the body is not essential for survival.

Internal movement refers to the ability of an organism to move from one place to another.

The bending of a plant towards light is an example of an organism responding to an external stimulus.

All living organisms grow in size and complexity during their life cycle.

Metamorphosis involves a complete change in an organism's body structure, while puberty is a gradual process of development.

Reproduction is a necessary process for the survival of a species, but not for the survival of an individual organism.

The process of respiration involves taking in carbon dioxide and releasing oxygen.

The term "encephalitis" is derived from Greek words meaning "brain" and "inflammation of".

The term "heterotroph" is a combination of Greek words meaning "other" and "feeder".

The "histo- " root in the word "histology" means "study of".

The root word "neuro" in the term "neuralgia" means "nerve".

A compound light microscope requires thin specimens because light needs to travel through them to reach the lens.

The diaphragm of a microscope controls the amount of light reaching the specimen.

The ocular lens of a microscope has a magnification of 100x.

The objective lens with a magnification of 40x has a field of view (FOV) of 0.5mm, which is equivalent to 500 μm.

An organism covering 1/2 of the medium power field is 1000 micrometers long.

A drawing magnification of 100X would result from an organism covering 1/5 of the high power field and being drawn 10 mm long.

An organism that fits into the diameter of the low power field 14 times is 357 millimeters long.

An organism that is 200 micrometers long and is drawn 15 cm long has a drawing magnification of 750X.

An object covering 1/5 of the medium power field is 400 micrometers large.

An object covering 1/10 of the high power field is 5 micrometers large.

An organism that measures 357 micrometers long, when drawn with a magnification of 30X, results in a drawing that is 10.71 millimeters long.

An object covering 1/15 of the low power field is 400 micrometers large.
