Answer 3

biodiversity

Question 4

French naturalist in
the 1800’s

the organic evolution of
animals

Answer 4

Jean baptist Lamarck

Question 5

Assumptions of Lamarck

on Organic Evolution

Answer 5

Adaptation (environment)

Organisms were driven from
simple to complex forms

Question 6

British Naturalist in 1901

The Origin of Species (Theory of common ancestry)

Answer 6

Charles Darwin

Question 7

Evolutionary evidences

Answer 7

Fossil records

Biochemical evidences

Comparative anatomy

Observable evidences

Question 8

Nitrogenous base sequence in DNA are all the same.

Answer 8

Biochemical evidence

Question 9

Due to the changing
environment,
organisms change
structures to be fit in
the environment

Same structures,
different functions

Answer 9

Comparative anatomy

Question 10

Organisms with the best traits reproduce and produce
offspring

Organisms with undesirable traits become extinct

Answer 10

Theory of natural selection

artificial selection (genetic modification)

Question 11

Evolutionary process in which a new species arise from an

existing species

Answer 11

Speciation

Question 12

Causes of speciation

Answer 12

Geographical Isolation

Reduction of Gene Flow

Question 13

Scientists who developed gas laws

Answer 13

Robert Boyle

Jacques Charles

Joseph Louis Gay-Lussac

Question 14

used to describe the behavior of gases.

Answer 14

Kinetic Molecular Theory

Question 15

kinetic molecular theory assumptions

Answer 15

Gases consists of tiny particles.

Volume of the individual particles
can be assumed to be zero.

Particles are in constant, random
motion.

Particles do not attract nor repel
each other.

The average kinetic energy particles
is directly proportional to the
temperature of the gas.

Question 16

Quantifiable properties of gases:

Answer 16

Volume

Pressure

Temperature

Number of Particles

Question 17

Amount of space occupied by matter

Measured in L or cm3

depends on
temperature and pressure.

Answer 17

volume

Question 18

force per unit area

Answer 18

pressure

the higher the place, the lower the pressure

Question 19

average kinetic

energy of an object

Answer 19

Temperature

Question 20

The higher the amount of
moles, the higher the amount of
substance.

how many particles can I fit in that space

Answer 20

No. of particles

Question 21

Irish-born philosopher who did
investigations in physics, chemistry,
etc.

Studied the behavior of gases

Famous for his J-tube experiment

Answer 21

Robert boyle

Question 22

Temp x KE relationship

Answer 22

Directly proportional

more heat, more KE, more movement

Question 23

Pressure x Volume Relationship

Answer 23

inversely proportional

pressure increase, volume decrease

Question 24

French scientist

Provided an explanation of how hot
air balloons work

A larger volume is occupied when
gas is heated because hot air is less
dense than cold air.
