Unit 1: What is life?

Macromolecules:

are biologically important molecules that are technically polymers. Polymers are made by combining smaller units called monomers

Energy:

can be defined as the capacity to do work or to make a change in the location, temperature, or structure of matter.

development:

structure and function change in an orderly way as an organism passes through its life cycle.

Homeostasis:

The ability or tendency of organisms and cells to maintain stable internal conditions is called..

Atom:

Basic unit of matter

To be considered alive, something must:

Be made of materials organized in a hierarchical pattern. Use energy and raw materials to survive. Sense and respond to changing environments and maintain internal stability, or homeostasis. Grow, develop, and reproduce. Be part of a population that evolves.

is the molecule of inheritance. It has additional roles, but one of the main things it does is encode proteins.

DNA

flows through living systems, changing forms as it goes.

Energy:

Biotic:

Living

Classification of Matter:

Matter is any substance that has mass and takes up space.

Abiotic:

Nonliving

Natural Selection:

helps explain how groups of organisms become well-suited, or adapted, to their surroundings.

Molecule:

is a chemical structure consisting of at least two atoms held together by a chemical bond.

Evolution:

is a scientific theory that explains how and why life changes over time.

Growth:

is just an increase in size.

Matter:

is traditionally defined as anything that has mass and takes up space.

reproduction:

occurs when an individual organism passes on its genetic information to a newly independent organism, or offspring.
