What sexual reproduction give species?
The most important characteristic of sexual reproduction is genetic variability between parents and offspring.
What is climate variability?
Climate variability is unknown
What variety of organisms within an ecosystem is characteristic of which type of diversity?
Biodiversity is the variability among living organisms from all sources including, inter alia, terrestrial, marine and other aquatic ecosystems and the ecological complexes of which they are a part; this includes between species, and of ecosystems.
Do plants decrease genetic variability when spores are produced?
No
What type of cell division increases genetic variability?
Meiosis
What tool is most useful for viewing the variability of a quality characteristic?
Control Charts
How much data is needed to have a representative sample of the population?
The answer depends on the variability of the characteristic that is being measured.
What sexual reproduction give species?
The most important characteristic of sexual reproduction is genetic variability between parents and offspring.
Why is a census preferred to?
1) when the fixed cost of selecting a sample is high. 2) when there is high variability in the characteristic been measured. 3) when the population is small.
What is climate variability?
Climate variability is unknown
Can variability be negative?
The usual measures of variability cannot.
Darwins observation of overproduction in a species was that what?
While living organisms tend to overprodue, the population still remains stable over time and across generations. therefore, there is competition, and success in competition is due to variability. Competition and variability together function to select the most adaptive characteristic, giving us natural selection
What is a definition for rainfall variability?
The degree to which rainfall amounts vary across an area or over time is called 'rainfall variability'. It has two components viz. saptial variability and temporal variability.
Why do smaller populations need larger sample sizes?
They do not. Population size does not affect the sample size. The variability of the characteristic that you are trying to measure and the required accuracy will determine the appropriate sample size.
Is range a measure of variability?
Yes. The greater the range, the greater the variability.
What is the meaning of minimizes the within-class variability while at the same time maximizing the between-class variability?
minimizes the within-class variability while at the same time maximizing the between-class variability.
An advantage of sexual reproduction is?
An advantage of a sexual reproduction is that it is able to produce more offspring because of the mate. Children are different from the parents and more genetic variation species.
