Hypothesis

Before doing an experiment a scientist writes the following statement, "If water is present, then the growth of mold on bread may accelerate". This is an example of a(n)

Thickness of fur

Dr. Thalamus wanted to know if a new hormone would increase the thickness of fur on rabbits. Twenty rabbits of the same type and age were placed into two groups. Group A was given the hormone every week. Group B was not given the hormone. What would be the dependent variable?

Hormone

Dr. Thalamus wanted to know if a new hormone would increase the thickness of fur on rabbits. Twenty rabbits of the same type and age were placed into two groups. Group A was given the hormone every week. Group B was not given the hormone. What would be the independent variable?

was fed the same amount without the food additive

A biologist wants to test the effectiveness of a new food additive on causing growth in mice. An effective control group would be on that

How do viruses reproduce?

the ability to nourish

In order to be classified as living, an organism must have among other characteristics

catalysts used in all chemical reactions

What are enzymes?

Nucleus

Which cell structure contains the cell's genetic material and controls the cell's activities?

Lysosomes

Which organelle is the recycling center that breaks down worn cell parts using digestive enzymes?

Golgi apparatus

What cell part is labeled by the arrow in the image below, which helps package substances?

Ribosomes

Which organelle is the site of protein synthesis?

Cell Walls

Structures that support and give shape to plant cells are

prokaryotic cells lack a true nucleus and membrane bound organelles

Prokaryotic cells differ from eukaryotic cells in that

cell wall and chloroplast

What two structures are found in plant cells that are not found in animal cells?

mitochondria

Which organelle converts food into energy?

Homeostasis

Sweating is a process by which excess water and salts and a small amount of urea are removed from the human body. Sweating involves the skin and the excretory system. This ability of an organism to maintain a stable internal environment is called

stores food, water, waste, etc.

What is the function of the cell part that is labeled by the arrow in the image below?

Semi-permeable

The type of membrane that allows only certain molecules to pass through is

passive transport

The movement of substances into and out of the cell without the use of energy is called

osmosis

The movement of water across a semi-permeable membrane from an area of high water concentration to an area of low water concentration is called

Hypotonic

If the solution surrounding a cell has a lower concentration of solutes than inside the cell, water will move into the cell through osmosis, causing it to expand. What kind of solution is surrounding the cell?

an area of high concentration to an area of low concentration

Diffusion is the movement of molecules from

the organism will shrink

Organism Y has an internal salt concetration of 3 g/L. Solution A has a salt concentration of 5 g/L. What will most likely happen to the organism if it is placed in solution A?

water to move into the cell

An animal cell that is surrounded by fresh water will burst because the osmotic pressure causes

an Amoeba wraps its' membrane around a small unicellular organism to eat it

Which of the following is an example of phagocytosis?

active transport

Potassium molecules move from areas of LOW concentration to HIGH concentration through a protein channel in the cell membrane. This would be an example of

swell, but stop when the cell wall prevents further expansion

If a plant cell is placed in distilled water, it will

Isotonic

A red blood cell has been placed in a solution. There is no net movement of water. This means that the solution is

Exocytosis

When vesicles are used to release waste product out of the cell, it is called?

ATP

The chemical energy supply for all living cells s contained in a molecule that, when broken down, releases the energy so that it may be used for activities such as muscle contractions, photosynthesis, and locomotion. This molecule that is a storehouse of energy is
