Chapter 1 - Introduction To Biology Pt 1

Question 1

What is Biology?

Answer 1

The scientific study of life

Question 2

Order

Answer 2

The highly ordered structure that typifies life

Question 3

Reproduction

Answer 3

The ability of organisms to reproduce their own kind

Question 4

Growth and Development

Answer 4

Consistent growth and development controlled by inherited DNA

Question 5

Energy Processing

Answer 5

The use of chemical energy to power an organism’s activities and chemical reactions

Question 6

Response to the Environment

Answer 6

An ability to respond to environmental stimuli

Question 7

Regulation

Answer 7

An ability to control an organism’s internal environment within limits that sustain life (homeostasis)

Question 8

Evolutionary Adaptation

Answer 8

Adaptations evolved over many generations as individuals with traits best suited to their environments have greater reproductive success and pass their traits to offspring (also know as natural selection)

Question 9

Biological Organization

Answer 9

Biosphere -> Ecosystem, Community -> Population -> Organism -> Organ -> Tissues -> Cells -> Organelle -> Molecule

Question 10

Biosphere

Answer 10

Biggest level; all of the environments on Earth that support life

Question 11

Ecosystem

Answer 11

Level below Biosphere; all the organisms living in a particular area and the physical components with which the organisms interact

Question 12

Community

Answer 12

Third Level below Ecosystem; the entire array of organisms living in a particular ecosystem

Question 13

Population

Answer 13

Below Community; all the individuals of a species living in a specific area

Question 14

Organism

Answer 14

An individual living thing within a population

Question 15

Organ System

Answer 15

Several organs that cooperate in a specific function to sustain an organism

Question 16

Organ

Answer 16

A structure composed of tissues that provides a specific function in an organ system

Question 17

Tissues

Answer 17

A group of similar cells that perform a specific function to make up an organ

Question 18

Cells

Answer 18

The fundamental unit of life that makes up tissues

Question 19

Organelle

Answer 19

A membrane bound structure that performs a specific function within a cell

Question 20

Molecule

Answer 20

A cluster of small chemical units calls atoms held together by chemical bonds

Question 21

Emergent Properties

Answer 21

Arise in each step upward in the hierarchy of life; from the arrangement and interactions among component parts

Question 22

At which level of Biological Organization does life emerge?

Answer 22

Cellular Level

Question 23

What unit regulates its own internal environment, takes in and uses energy, responds to its environment, develops and maintains complex organization, and is capable of reproduction?

Answer 23

Cells

Question 24

What do all cells have?

Answer 24

1. A membrane that acts as a security wall

2. DNA as their genetic information (for reproduction)

Question 25

The two types of Cells include:

Answer 25

Prokaryotic and Eukaryotic

Question 26

The cells that were first to evolve, are simpler, and usually smaller

Answer 26

Prokaryotic

Question 27

Cells that contain membrane-enclosed organelles, including a nucleus with DNA, and are found in plants, animals and fungi.

Answer 27

Eukaryotic
