Answer 8

Bio diversity is the diversity of life forms in an environment.
Species diversity is the number of species in a region or particular ecosystem.
Genetic diversity is a measure of genetic variation among individuals in a population.

Question 9

what is a species

Answer 9

species are a group of organisms that is distinct from another group and its morphology, aka body form in structure behavior or biochemical properties

Question 10

define- speciation and background extinction rate

Answer 10

Speciation is the evolution of new species.
Background extinction rate is the average rate at which species become extinct over the long term.

Question 11

Define anthropogenic.

Answer 11

derived from human activity

Question 12

Question 15

define replication and theory

Answer 15

Replication-The data collection procedure of taking repeated measurements
Theory- a hypothesis that has repeatedly tested and confirmed by multiple groups of researchers and has reached wide acceptance

Question 16

defined natural experiment

Answer 16

A natural vent that acts as an experimental treatment in an ecosystem

Question 17

what is the scientific method and what are the stages of it

Answer 19

dependent variables are variables are dependent on other factors, while independent variables are not dependent on other factors

Question 20

Answer 20

Null hypothesis of protection that there is no difference between the groups or treatments that are being compared.

Question 21

define sample size

Answer 21

Sample size is the number of times and measurement is replicated in a data collection.

Question 22

define accuracy,precision, and uncertainty

Answer 22

How close the repeated measurements of a sample are to one another is _precision
accuracy -is how close a measured value is to the actual or true value
uncertainly- is an estimate of how much a measured or calculated value differs from a true value.

Question 23

defined natural experiment

Answer 23

A natural experiment, occurs when a natural event acts as an experimental treatment in an ecosystem. for an example, the volcano that destroyed thousands of acres of forest provides a natural experiment for understanding large-scale forest regrowth
