Chapter 1- The Scientific Study of Life

Asexual Reproduction

is when one parent is involved and offspring are genetically identical to the parent.

Sexual Reproduction

is when two parents are involved and offspring are genetically different from each parent.

Primary Producers

: extract energy and nutrients from the non living environment.

Domains

are divided into kingdoms.

Protista

Eukarya, : Most diverse group of eukaryotes with multiple lineages like amoebas, slime molds, algae, and more.

Homeostasis

is the process by which a cell or organism maintains internal equilibrium.

Prokaryotic

: single celled organism with no membrane bound organelles.

Decomposers

: Consumers that obtain nutrients from dead organisms and organic wastes.

Plantae

Eukarya, : Producers that capture light from the sun and create energy that is passed to consumers and decomposers and are autotrophs (Autotrophs)

Development

: changes that occur as an organism matures, including growth, cell specialization, and other processes.

organelles

Eukaryotic: has membrane bound .

external digestion

Eukarya, Fungai: Natures decomposers and heterotrophs by .

Consumers

: obtain energy and nutrients by eating other organisms.

Growth

: an increase in an organisms size, usually by way of cell division.

Cells

use DNA top produce proteins which carry out the work that do.

scientific theory

A(n) is a broad explanation for a natural phenomenon.

Hypothesis

: A testable idea to answer a question.

Independent Variable

: What is changing.

This organization leads to Emergent Properties

components interact, and the whole is greater than the sum of parts

Dependent Variable

What is measured

Standardized Variable

Held constant for all subjects

Control Group

Baseline used for comparison

Experimental Group

May or may now show different results from control group

What are the five characteristics of life?

Organization, Reproduction/Growth/Development, have DNA, requires energy, and requires homeostasis
