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.
