DNA and Morphological features

Question 4

WHAT ARE THE SECTIONS OF THE BIONOMIAL SYSTEM (in order)

Answer 4

Kingdom, Phylum, Class, Order, Family, Genus, Species

Question 5

WHAT IS THE BIONOMIAL SYSTEM?

Answer 5

An order of categories that help to classify any organism

Question 6

WHAT IS A SCIENTIFIC NAME MADE OUT OF?

Answer 6

The Genus (capital letter) then the Species (lowercase letter)
e.g. Homo sapiens

Question 7

WHY IS IT IMPORTANT TO USE SCIENTIFIC NAMES?

Answer 7

It’s the universal language of classification

Question 8

WHAT IS AN ADAPTATION IN AN ORGANISM?

Answer 8

A morphological or behavioural feature that allows a living thing to survive in its habitat

Question 9

WHAT IS INTRASPECIFIC COMPETITION?

Answer 9

Competition between two of the SAME species

Question 10

WHAT IS INTERSPECIFIC COMPETITION?

Answer 10

Competition between two from DIFFERENT species

Question 11

WHAT DOES BIODIVERSITY PROVIDE?

Answer 11

• Food
• Medicine
• Industrial material

Question 12

WHAT IS THE DEFINITION OF BIODIVERSITY?

Answer 12

A variety of species or individuals in one area

Question 13

WHAT CAN BIODIVERSITY BE PROTECTED BY?

Answer 13

• CITES (making sure that trade doesn’t threaten a species’ survival.)
• Sites of Special Scientific Interest (an area of conservation that contains rare species)
• Captive breeding programmes. (These include zoos, aquariums, and safari parks)
• National parks.
• Seed/sperm banks (Sperm, eggs and seeds can be ‘banked’ in they are threatened with extinction)
• Local biodiversity action plans.

Question 14

WHAT IS A BIOLOGICAL CONTROL?

Answer 14

Biological control involves deliberately introducing a living organism to control the population of another pest species

Question 15

WHAT IS AN ALIEN SPECIES?

Answer 15

Alien species are organisms that are accidentally or deliberately introduced into habitats where they do not naturally occur

Question 16

WHEN DO ALIEN SPECIES BECOME INVASIVE?

Answer 16

• they have no predators in the area and the population grows out of control
• they compete with native species and cause that species to die out in the area
• they prey on native species, reducing their population
• they carry a disease that existing native species are not immune to.

Question 17

WHAT IS THE PRACTICAL USED TO SAMPLE THE BIODIVERSITY OF AN AREA?

Answer 17

Random quadrats and/or transects along a set distance
