What is biodiversity?

- genetic diversity

- species diversity

- ecosystem diversity

Which community is more diverse?

Which community is more diverse?

The areas have equal species richness, but area 2 has a higher evenness and therefore a higher species diversity.

What is NOT part of Darwin's evolution's theory

1. Natural selection
2. Adaptation to circumstances
3. Survival of the fittest
4. Proof that God as Creator does not exist

Drag the missing words to the correct place in the text.

Darwin

changes

puzzle

apes

survive

fossils

what are the two basic ideas of Darwin's evolution?

What is natural selection?

Natural selection

Individuals that are best at surviving in their environment will produce more offspring 

NATURAL SELECTION

Animals best adapted to 

their environment, live 

longer and have a better

chance at reproducing

Adaptation

"the process of change by which an organism or species becomes better suited to its environment"

Variation due to mutation.

Are mutations always negative?

1. yes
2. no
3. no idea

What's the best description for
"mutation"?

1. A sudden change in an organism
2. A sudden change in a cell
3. A sudden change in a nucleus
4. A sudden change in the DNA

Sources of variation are

1. genes
2. environment
3. both are correct

Noem twee verschillen tussen DNA en RNA

Waarvoor wordt RNA gebruikt in de cel?

1. Om erfelijke informatie op te slaan in de celkern
2. Als kopie van DNA, zodat DNA in de kern kan blijven
3. Om DNA van te maken
4. Als kopie van DNA, zodat de ribosomen de code kunnen lezen

Welk organel maakt eiwitten?

1. Mitochondriën
2. Golgi systeem
3. Endoplasmatisch reticulum
4. Ribosomen

Wat betekent translatie?

1. hetzelfde als transcriptie
2. het aflezen van RNA door een ribosoom om eiwit te maken
3. het maken van een afschrift van het DNA: het RNA
4. het opvouwen van een eiwit

Hoeveel basen van het RNA vormen samen de code voor één aminozuur in een eiwit?

1. 1
2. 3
3. 9
4. 1000

Summary

Variation is caused by mutation.

Variation that heritable, will lead (under selection pressure) to natural selection.
Natural selection will lead to adaptation to the environment.

NATURAL SELECTION

Animals best adapted to 

their environment, live 

longer and have a better

chance at reproducing
