Evolution

Question 1

Evolution

Answer 1

Natural change of genes over millions of years. It’s the theory that organisms change with the passage of time as a result of natural selection

Question 2

Geological timescale

Answer 2

Is used to record the history of life on earth

Question 3

Evidence for evolution

Answer 3

Fossil records
Biogeography
DNA evidence
Descent with modification
Genetics

Question 4

DNA evidence

Answer 4

The more similar the DNA is is the more the organisms are related

Question 5

DNA evidence

Answer 5

The more similar the DNA is is the more the organisms are related

Question 6

Things were molecules

Answer 6

That had to replicate themselves in order for offspring to be produced, they formed due to extreme conditions at hat time

Question 7

The moving of tectonic plates to form laurasia and gondwanaland

Answer 7

Continental drift

Question 8

3 eras of the geological times ale

Answer 8

Palezoic, mesozoic and canozoic

Question 9

Before the cambrian period

Answer 9

Known as the pre cambrian period

Question 10

Fossils

Answer 10

Are mineralized remains of an. Organism that has lived in the past

Question 11

Genetic variation

Answer 11

Variety of genes that may differ from the maternal and paternal genes resulting in new genotypes and phenotypes

Question 12

Mutation

Answer 12

A sudden change in sequence or oder of nitrogeneous bases of a nuclei acid resulting in declines in genetics inherited

Question 13

Natural selection

Answer 13

Process by which organisms best suited to survive in the environment achieve greater reproduction successing passing advantageous characteristics onto future generations

Question 14

Palaeontology

Answer 14

Study of fossils

Question 15

Speciation

Answer 15

Process where new species are formed form the original population

Question 16

Transitional fossils

Answer 16

Show intermediate characteristics between two genera/species. It has common characteristics to both ancestor species and the descendant species that follow.

Question 17

Useful mutation

Answer 17

Advantages to the organisms and are passed from parent to offspring

Question 18

Variation

Answer 18

Refers to how organisms differ from each other

Question 19

Variation is caused by

Answer 19

Genes and environmental

Question 20

Selective breeding

Answer 20

When humans deliberately breed animals or pants together so that they can get the characteristics they want from the organisms

Question 21

How do cells communicate

Answer 21

Via the nervous system and hormone system (endocrine system)

Question 22

Variation causes

Answer 22

Cancer cell by radiation, carcinogenic and viruses

Question 23

Geological theory

Answer 23

Explains how the earth surface changes look now and how they were in the past and what caused the difference to occur

Question 24

Organic molecules

Answer 24

Pretend and fatty acids, the molecules are combined to form cell membranes

Question 25

Pangaea

Answer 25

It is given to the supercontinent that existed during the palezoic era

Question 26

Why did the dodo bird become extinct

Answer 26

The settlers that arrived on the island brought animals like dogs that ate the dodo’s eggs and they chopped down tres where the dodo bird lived and hunted them for food

Question 27

Adaptive evolution

Answer 27

Ensures individuals within a species have traits that allow them to survive and reproduce in a habitat

Question 28

Individuals die

Answer 28

When they fail to compete for food, reproduce or fight against Predators.

Question 29

Extinction

Answer 29

Species that no longer exist due to changes in the environment that reproduces its ability to survive an reproduce

Question 30

Charles dsrwin theory

Answer 30

Organisms evolve to adapt to the environment, organisms with adaptive features which allow reproduction and survals of the species while others die out.

Question 31

Trait

Answer 31

A distinguishing and inheritable charscteristic of an organism

Question 32

Charles proposed that evolution takes place

Answer 32

By natural and sexual selection

Question 33

Lamarckism

Answer 33

Things that we learn to inherit and changes were inheritable. Using or not using certain features can cause them to enlarge or shrink and determine if they are passed down to the next generation
Traists are acquired htorugh the overuse and under use of certain body sorts

Question 34

A fossil is

Answer 34

Completer organisms or remains, imprints or traces of an organism that is preserved in rocks, they are found in sedimentary rocks fokeed when clays and soil particles are carried from one palace to another

Question 35

Formations of oil

Answer 35

Marine organisms die and accumulate in stagnate water lacking oxygen. They are buried by classy to not decays but form hydrogen rich muds broken down by anaerobic bacteria. The oil sips into permeable rocks and gets trapped by impermeable rocks
