Question 2

Question 3

Endangered

Answer 3

Species of plants and animals that have a low population

Question 4

Answer 4

• store genetic material taken from endangered species to prevent extinction
• used for research

Question 5

Factors of extinction

Answer 5

• environmental disaster
• new predators
• tourism
• hunting
• disease
• habitat damage
• climate changer

Question 6

Interdependency in extinction

Answer 6

Question 7

Gene bank examples

Answer 7

• seed banks =dried seeds stored in -18.c freezers
• tissues= buds/cells of plants stored here
• cryogenic banks= seeds/embryos are stored here at very low temps using nitrogen

Question 8

Gene banks prevent extinction

Answer 8

• cells are taken/stored from endangered species in gene banks
• will be used for research and turned into stem cells
• embryo will be injected into similar species to be birthed
