biodiveristy

Question 1

what does biodiversity give an indication of?

Answer 1

both the Range of species and alos how evenely balanced the numbers of indicdulas are across difrrent species

Question 2

what is simpsons index?

Answer 2

meaure of biodiversity tht takes into account both the number of species and the number of individuals of eavh species

Question 3

when do we use density and when do we use %cover

Answer 3

d= anmials and %= plants

Question 4

what does simpsons index measure and what doesn’t it measure

Answer 4

it measures species diversity ut doesn’t measure ecosystem diversity eand genstic diversity

Question 5

what is ecodiversity?

Answer 5

represents the diversity of ecosystems within the biosphere

Question 6

what is a habiata?

Answer 6

refers to the place an organism lies

Question 7

what is an environment?

Answer 7

describes the conditons that affect organisms in a habitata

Question 8

what can the environment be split into?

Answer 8

abiotic and biotic

Question 9

what are ecosystems?

Answer 9

a community of organicms, interacting with one another and the associated envrinment

Question 10

what si the population?

Answer 10

it is madde up of all the members od the same species that occur in a particular area at a particular time

Question 11

what is a communtiy

Answer 11

a group of speices which occur in the same place at eh same time

Question 12

what is genetic diversity?

Answer 12

this refers to the genetic variblitiy of the species

Question 13

where is genetic varibilty greater? (variation of dna and genes)

Answer 13

in species that have become adapted to a wide range of environment. (species want to be this)

Question 14

what species will be more genetically varible

Answer 14

subject to higher rates of dna mutation

Question 15

What is the generic name

Answer 15

Indicates the genus to which the species belongs

Question 16

What is the specific or species name

Answer 16

Identifies the species to which an organisms belongs

Question 17

Why are tigers and lions classified as diffrent species

Answer 17

Hybrids tend to not occur in natural conditions

Question 18

Good for phylogenetic taxonmynover binomial

Answer 18

The different species in a genius do you not just have a large number of similarities, they also share a common ancestry i.e. they have evolved from a common ancestor

Question 19

How will diffrent species be more related

Answer 19

Grips of species that have shared a common ancestor more recently than other species will consequently be more closely related

Question 20

Why is cell structure important and

Answer 20

Cell structure differences are important in classifying organisms as plants fungi or animals

Question 21

How can length of time of separation from ancestors be evaluated

Answer 21

Analysing similarities in DNA, RNA or protein, using the degree of change at gene or a biochemical level as a type of molecular clock.

(This is because once two or more species evolved from an ancestral species, certain mutations will spontaneously take place in the DNA of one of the species but not necessarily in the others. Or tiny species will increasingly differ in their DNA.
