What is the definition of a hypothesis?

An educated guess about the relationship between two variables, or the outcome of an experiment.

100

What is the difference between "abiotic" and "biotic"?

Abiotic = nonliving

Biotic = living

100

What is the most basic structure of life?

The cell.

100

Give an example of an organism that performs photosynthesis.

Examples: plants, trees, grass, algae, etc.

100

What organ system is the stomach a part of?

The digestive system.

200

What is the difference between an independent variable and a dependent variable?

The independent variable is a variable that is changed (cause); the dependent variable is the outcome (effect).

200
What is the primary source of energy for producers?

The sun.

200

What is the molecule created in the mitochondria that is used for energy?

ATP.

200

What are the products of cellular respiration?

CO2, H2O, and ATP.

200

Which body system provides structure, protection of organs, and movement to the body?

The skeletal system.

300

What is a "constant variable"?

A constant variable is a variable that remains the same in all experimental groups.

300

What is "carrying capacity"?

"Carrying capacity" is the population size of a species that an environment can sustain.

300

What is a difference between prokaryotes and eukaryotes?

Prokaryotes: single-celled organisms without a nucleus.

Eukaryotes: organisms that can be multicellular with a nucleus.

300

Which organelle performs photosynthesis?

Chloroplasts.

300

What is the name of the balance of all human body functions that body systems try to maintain?

Homeostasis.

400

Why is it important to have a control group in most experiments?

It is important to have a control group because the experimental group (which received the treatment) is compared to the control group (which did not) to tell if the treatment caused any changes.

Can you give three examples of populations that live in NYC?

Some examples: humans, rats, pigeons, cats, dogs, etc.

400

What are two organelles that plant cells have but animal cells do not have?

Cell wall and chloroplasts.

400
Is the Krebs Cycle a part of photosynthesis or cellular respiration?

Cellular respiration.

400
Which body system does not have a direct role in maintaining homeostasis?

The reproductive system.

500

What are two ways to improve experiment validity?

1. Repeat the experiment multiple times

2. Conduct the experiment with a larger sample size.

500

What is the definition of ecological succession?

Ecological succession is how the structure of a biological community evolves over time.

500

What is the name of the passive movement of molecules from areas of higher concentration to areas of lower concentration?

Diffusion.

500

What is the chemical equation of photosynthesis?

6CO2 + 6H2O --> C6H12O6 + 6O2

What does the endocrine system do?

The endocrine system releases hormones into the bloodstream to regulate specific organs.
