Regulation

Answer 5

Ability to maintain constants. i.e. blood flow, warmth

Question 6

Reproduction

Answer 6

Ability to reproduce

Question 7

Energy processing

Answer 7

Eating and the cycle of energy in the environment.

Question 8

Evolution Adaption

Answer 8

Evolving to your environment. i.e. snow leopards vs normal leopards.

Question 9

Growth and Development

Answer 9

inherited gene information.

Question 10

Hierarchy of size (small->big)

Answer 10

Atoms -> Molecules -> Organelles -> Cells -> Tissue -> Organs -> Organ system -> Organism -> Population (Same species) -> Community -> Ecosystem -> The BIOSPHERE

Question 11

Cellular basis of life

Answer 11

1. The cell is the smallest unit capable of all life activities
2. All cells come from other cells (problem with evolution theory)

Question 12

2 Major cell types

Answer 12

Prokaryotic and Eukaryotic

Question 13

Prokaryotic cells

Answer 13

Pro-before; karyo-nucleus.
Lacking a nucleus & membrane enclosed organelles.

2 domains.
1.Domain Bacteria
2. Domain Archaea

Question 14

Eukaryotic Cells

Answer 14

Eu-with; karyo-nucleus.
Contains nucleus & membrane enclosed organelles

1 domain:
Domain Eukarya

Question 15

Chromosomes in a dividing cell

Answer 15

Information within cells, structures called chromosomes contain genetic material in the form of DNA.

Question 16

Genomics

Answer 16

Studying an entire section of genes (DNA)

Question 17

Genome

Answer 17

entire “library” of genetic instructions that an organism inherits. Chromosome code.

Question 18

Proteomics

Answer 18

Studying an entire section of proteins

Question 19

Ecosystem Dynamics

Answer 19

1. Producers: photosynthetic organisms
2. Consumers: organisms that feeds on other organisms or its remains.

Question 20

Negative and positive feedback

Answer 20

Negative: stop doing something i.e. blood sugar levels
Positive: Keep doing something i.e. blood clotting

Question 21

Taxonomy

Answer 21

Scientific study of naming, defining, & classifying groups of biological organisms based on shared characteristics

Question 22

Domain Bacteria

Answer 22

Most widespread & diverse prokaryotes. Are now classified into multiple kingdoms. Typically live in human friendly environments.

Question 23

Domain Archaea

Answer 23

Prokaryotes, multiple kingdoms. Tend to live in extreme environments

Question 24

Domain Eukarya

Answer 24

4 kingdoms:
1. Plantae
2. Fungi
3. Animalia
4. Protsits

Question 25

Kingdom Protists

Answer 25

Single to simple multicellular eukaryotes. Hard to classify. Most numerous & diverse of eukaryotes.

Question 26

Levels of Classification

Answer 26

DK PC of GS 1. Domain 2. Kingdom 3. Phylum 4. Class 5. Order 6. Family 7. Genus 8. Species

Question 27

Unity in diversity

Answer 27

Similarities between species w/ no relation

Question 28

Origin of life: Evolution

Answer 28

Origin by Evolution from molecules...descent with modification.

Question 29

Origin of life: Creation

Answer 29

Origin by intelligent design w/ microevolutions

Question 30

Natural Selection vs Structure fits function

Answer 30

Natural Selection: Best genetics survive and reproduce, passing on the good genes. Structure fits function: Things are good at what they were designed to be good at.

Question 31

Common Ancestor

Answer 31

Everything came from a common ancestor, which is why a bat has matching traits with a horse, whale and a human.

Question 32

Natural Selection

Answer 32

1. Variation: very similar finches w/ slight differences 2. Overproduction: lead to many micro evolutions; better chance of survival 3. Competition: Competition lead to weaker & inferior genes dying out 4. Inheritance of fitness: Passing down genetic makeup, better genes reproduce.

Question 33

Inquiry

Answer 33

Search for information & explanation of natural phenomena

Question 34

Discovery science

Answer 34

Discovery based science. Uses scientific method. Aims to find new patterns, correlations, and form hypotheses through the analysis of large-scale experimental data.

Question 35

Data

Answer 35

Recorded observations. 2 types: 1. Qualitative: observations/recorded descriptions 2. Quantitative: Numerical based. Stats.

Question 36

Inductive reasoning

Answer 36

Conclusions reached by analyzing observations. Specific to general

Question 37

Deductive Reasoning

Answer 37

General to specific, If-Then statement. Prediction of result if hypothesis is discovered to be true.

Question 38

Scientific method

Answer 38

Observe -> research/ask a question -> hypothesis -> null hypothesis/predictions -> test -> analyze (repeat) -> report.

Question 39

Controlled Experiments

Answer 39

You control one group & compare those results to the other groups

Question 40

Independent variable

Answer 40

Factor being manipulated. The one you control.

Question 41

Dependent variable

Answer 41

Factor being measured/predicted according to independent variable.

Question 42

Limitations of science

Answer 42

It is impossible to control every variable

Question 43

Theories

Answer 43

Broader than hypothesis. Supported by many studies. Can be modified/changed if the need and support arises.

Question 44

Technology

Answer 44

Any method or device that applies scientific knowledge for a specific purpose.
