false
Natural Selection is the change in the characteristics of living things over time.
false
Simple life forms like bacteria, have simple chemistry.
false
Simple life forms, Like bacteria, do not grow and develop.
false

false
A cell is the basic unit of the structure and ______________ of living things.
function
theory that the characteristics of living things are controlled by genes that are passed from parents to offspring
gene theory
Maintaining a stable internal environment
homeostasis
The process of maintaining a stable internal environment is _________.
homeostasis
process of maintaining a stable environment inside a cell or an entire organism
homeostasis
Homeostasis is?
maintaining a stable internal environment
The process by which evolution occurs
natural selection
evolutionary process in which some living things produce more offspring than others so the characteristics of organisms change over time
natural selection
Evolution
occurs by natural selection, is a change in the characteristics of living things over time, explains how modern organisms have descended from ancient life forms

population
An adaptation is a characteristic that helps a living thing survive and ______________ in a given environment.
reproduce
___________ is the process by which living things give rise to offspring.
reproduction
process by which living things give rise to offspring
reproduction
