• homeostasis

• photosynthesis

• reproduction

1. when a higher concentration of a solute is separated from  a lower concentration by a semi permeable membrane.

• concentration gradient

• hypothesis

• meiosis

• cellular respiration

Many types of trees lose their leaves in the winter to avoid freezing. This is an example of

• concentration gradient

• photosynthesis

• response to stimuli

• mitosis

The action of a white blood cell engulfing a bacterium is

• osmosis

• mitosis

• meiosis

• phagocytosis

 is the movement of water into and out of cells

• osmosis

• phagocytosis

• fertilization

• response to stimuli

The first cell of a baby that results from fertilization is called a(n)

• hypothesis

• osmosis

• zygote

• gamete

A polymer is a (macromolecule/micromolecule) is composed of smaller units called

• stimuli

• monomers

• zygotes

• ribosomers

What is the first explanation of a problem? (It is sometimes called an "educated guess.")

• response to stimuli

• meiosis

• independent variable

• hypothesis

1. A new life cycle begins with

• 1. meiosis/ fertilization

• photosynthesis/ mitosis

• homeostasis / fertilization

• cellular respiration / meiosis
