The first step of the scientific method

Observation

100

Give an example of something that is NOT alive

Lots of answers!!!

100

This is stored in the bonds of molecules.

potential energy

100

This type of cell contains the structure shown in the vivid colors.

eukaryote

Give a general definition of passive transport.

a spontaneous movement of ions and other substances across cell membranes without need of energy input

200

In an experiment that tests the effect of Miracle-Gro on plant growth this is the dependent variable.

plant growth

200

This is one of the characteristics of life.

Metabolism, control, generative, and response processes; unique structural organization

200

How many electrons can fit in the second energy level (of an atom)?

eight

200

Rough endoplasmic reticulum are covered by these structures.

ribosomes

200

The term for the diffusion of water

osmosis

300

We fail to reject this when an independent variable has no effect on the dependent variable

Null hypothesis

300

This is the scientific study of life.

biology

300

This is the outermost energy level and determines whether atoms bond together or not.

valence

300

These two membrane-bound organelles are similar in that both are involved in energy transformation.

chloroplast and mitochondria

300

This is the unit of energy required for active transport

ATP

A shrimp swims away when you shine a light on it.  This is known as

negative taxis

400

All living things are made (composed) of...

cells

400
How might an unstable atom become stable?

By sharing electrons with another atom (or more); By transferring electrons

400

These structures are key to the division of a cell into two.

centrioles

400

These are the scientific terms that refer to cell eating and drinking.

phagocytosis and pinocytosis

500

State a prediction that represents the following alternative hypothesis: Green beans have an effect on a person's heart rate.

If green beans have an effect then a person's heart rate will decrease whenever they are eaten.

500

An example of a generative process is 

growth, reproduction

500

How is the pH of a solution controlled or determined?

the concentration of hydrogen ions [H+]

500

This is the one organelle found in a prokaryotic cell

ribosome

Using the correct terminology, what is the direction of movement of water through a semi-permeable membrane when one side has fewer solutes (and more water) than the other.

hypotonic to hypertonic (from fewer solutes/more water to more solutes/less water)
