An organized way of gathering and analyzing evidence about the natural world

When you notice something you have made a(n)

The smallest unit of life

Living thins do NOT have to:

Biology is the study of

Living things

A generally accepted principle, supported by large amounts of experimental evidence.

Levels of organization from smallest to largest

Hypotheses must be

This will not change during an experiment

The cloud around the nucleus of an atom contains

Ionic bonds result from

Covalent bonds result from

Isotope are atoms of the same element, but they contain a different amount of

These are atoms that have lost or gained electrons

These ions LOSE electrons

The atomic mass of an element =

Organic compounds always contain

Covalent double bonds between two atoms result in __________ total shared electrons

Water molecules are ________________ molecules

amino acids are the monomer of

monosaccarides are the monomers of

nucleotides are the monomers of

The pH scale indicates the concentration of _________________ ions

These special proteins can influence the rate of chemical reactions

This is NOT a function of proteins:

Cells are classified based on whether they have a __________ or not.

A cell nucleus

This controls what enters or leaves a cell

This organelle packages and prepares substances for transport

This cell organelle produces ATP during cellular respiration

Proteins are produced by the

Extremely active cells would need to have many

Phospholipid heads of the cell membrane are _________, while the tails are ______.

Plants and some bacteria have a _______________ that supports and protects the cell.

Eukaryotes usually have

The gel like substance in a cell

Microfilaments and microtubules make up the

Some cells use this whip - like structure for movement

particle in a solution are evenly distributed at

The natural movement of particles from high to low concentration.

This requires energy because particle are being moved from low concentrations to high.

Moving larger particle into the cell, requires energy.

Moving larger particle out of the cell, requires energy

Cell "drinking" of fluids, requires energy

A cell placed in a(n) ____________________ solution will eventually burst due to a net movement of water IN

A cell place in a(n) _____________ solution will shrivel due to movement of water out of the cell

A cell placed in a(n) _______ solution will not change due to equal net movement of water in /out.

Facilitated diffusion requires

Diffusion of water?

What must be broken to release energy for the cell to use

What is needed for photosynthesis

The organelle where photosynthesis takes place

In chloroplasts, chlorophyll is found in membrane-disks called:

This fluid fills in the space inside the chloroplasts, surrounding the thylakoids

Which is NOT a product of the light-dependent reaction of photosynthesis

What is the main product of the Light Independent Reaction (Calvin cycle) during photosyntheis?

All of the energy stored in the chemical bonds of the food you eat initially came from the

Which of these is NOT needed for the light independent reaction (calvin cycle)?

The first step for both aerobic and anaerobic respiration is:

This molecule is broken down into two molecules of pyruvate during glycolysis

If oxygen is present, the next step after glycolysis is:

If oxygen is NOT present, _____________________ will occur in animal cells

During fermentation, animal cells produce ________________ while unicellular organisms produce _____________.

The __________________________________ of aerobic cellular respiration requires oxygen.

What is the correct sequence of aerobic cellular respiration?

About how many ATP are produced in the electron transport chain?
