chapter one

Question 1

What is Biology?

Answer 1

The study of life and all living organisms

Question 2

What is a hypothesis?

Answer 2

Hypothesis is a tentative (not certain) answer to a scientific question - educated guess

How do Hypothesis differ from predictions?

Answer 3

A prediction is a specific outcome or result that is expected to occur if the hypothesis is correct. It is often derived from the hypothesis.

Question 4

Process of science

Answer 4

Exploration - Hypothesis - Prediction - Experiment

Question 5

What is an essential part of science?

Answer 5

Peer Review

Question 6

what does natural selection mean

Answer 6

Living organisms adapt and change in response to environmental conditions

Question 7

What are genes?

Answer 7

Heredetary units of information.

Question 8

What are controlled experiments

Answer 8

scientific tests designed to investigate the effect of a single variable while keeping all other variables constant.

Question 9

Do you change experimental or controlled

Answer 9

experimental

Question 10

Should both groups be similar or different in controlled groups

Answer 10

As close to similar

Question 11

What does placebo mean

Answer 11

A medically ineffective treatment that allows the placebo group to serve as a controlled group

Question 12

what is single blind experiment and why do people do it

Answer 12

Researcher knows which treatment a participant receives but participant does not

Question 13

What are the properties of life

Answer 13

Order, Evolutionary Adaption

Question 14

What is the key difference between how energy and matter moves in ecosystem

Answer 14

Energy moves through an ecosystem (it exits and enter) where matter is recycled with an ecosystem

Question 15

What is the primary way by which energy leaves the body?

Answer 15

Heat

Question 16

What is the modern term for what Darwin Called descent with modification

Answer 16

Evolution

Question 17

What mechanism did Darwin propose for evolution?

Answer 17

Natural Selection

Question 18

What three word phrase summarized Darwins mechanism

Answer 18

unequal reproductive success

Question 19

What are the results of natural selection?

Answer 19

evolutionary adaption, inherited traits that enhance survival in an organisms specific enviornment

Question 20

what is the fundamental principle of life and the core theme that unifies all of biology

Answer 20

evolution

Question 21

what is recycled within an ecosystem

Answer 21

Nutrients

Question 22

do all scientific investigation follow steps in an order

Answer 22

No, different scientific investigations may proceed through the process of science in different ways

Question 23

what is intended to provide quality control

Answer 23

peer review

Question 24

anecdotal evidence

Answer 24

not systematically collected or analyzed and often lacks reliability or generalizability

Question 25

what properties of life apply to a car?

Answer 25

order, regulation, energy, processing, and response to the environment.

Question 26

what proporties of life don't apply to a car

Answer 26

grow, reproduce, or evolve and not composed of cells

Question 27

What are the five unifying themes that recur throughout our investigation of biology

Answer 27

1.the relationship of structure to function, 2.information flow, 3.pathways that transform energy and matter, 4.interactions within biological systems and 5.evolution

Question 28

Structure of function

Answer 28

Structure = What it looks like or how it's made. Function = What it does or its purpose.

Question 29

Refers to the relationship between the shape, form, or organization of a biological entity (structure) and the role it performs

Answer 29

Structure ***determines*** Function Function ***influences*** Structure

Question 30

information flow

Answer 30

It's like how messages move through a system to make sure everything happens at the right time and in the right way.

Question 31

at the microscopic level

Answer 31

every cell contains genes

Question 32

what are the chemical names of DNA's , molecular building blocks?

Answer 32

A,G,C,T

Question 33

what is the term for the genetic information that encodes for a protein?

Answer 33

Gene

Question 34

how does energy flow

Answer 34

enters as light energy and exits as heat energy

Question 35

energy processing 

Answer 35

how living things get and use energy to survive, grow, and do activities.

Question 36

level of bioligical organization

Answer 36

1.biosphere 2.ecosystem 3.communities. 4.populations 5. organisms 6. organ system and organs 7.tissues 8.cells 9.organelles 10. molecules atoms

Question 37

properties of life

Answer 37

1.order 2.Regulation 3.Growth and development 4.response 5. energy processing 6.evolutionary adaption 7. reproduction

Question 38

homostasias

Answer 38

Living things can control their internal environment to stay balanced. (regulation)

Question 39

Growth and Development

Answer 39

Growth is when living things get bigger. Development is when they change or get more complex as they grow.

Question 40

Response to the enviornment

Answer 40

Living things react to changes around them, like how plants turn toward the sun or how you sweat when you’re hot.

Question 41

energy processing

Answer 41

Living things need energy to do everything, like moving, thinking, and growing. They get energy from food or sunlight.

Question 42

biological level organization

Answer 42

atom-molecule-cells-tissues-organs-organsystem-organism-population-community-ecosystem-biosphere

Question 43

evolutionary adaption

Answer 43

Over time, living things can change to better survive in their environment. This is called evolution. These changes can happen slowly over many generations.

Question 44

Reproduction

Answer 44

Living things can make more of themselves to keep their species alive.

Question 45

Order

Answer 45

Everything in living things has a special organization. For example, your body is made up of cells, and those cells form tissues, organs, and systems. This order helps everything work smoothly.

Question 46

what is not a characteristic of all living organisms

Answer 46

composed of multiple cells

Question 47

Pseudoscience

Answer 47

Any field of study that is falsely presented as having a scientific basis.
