The answer to finish this sentence would be ''the amount of genetic variation in a population'' because environmental factors can either increase or decrease a population.
Options:
- a lake
- a prairie
- the land an organic farmer uses to raise crops to feed his dairy cattle
- a large island in the tropics that has snowcapped mountains
Answer:
a large island in the tropics that has snowcapped mountains
Explanation:
The land a farmer uses is likely to be quite highly regulated in order to ensure that his dairy cattle thrive. That means the growth of certain plants will be controlled, and this will likely impact diversity.
A lake and a prairie could have diverse and balanced ecosystems. However, due to the limited habitat are likely only to harbour specific organisms. E.g. the lake will only harbor organisms that thrive in water environments.
A large island will, first of all, have a lot of space to support diversity. It is in the tropics, meaning it will have species suited to a hot and wet environment. Since it is an island, there will also be the involvement of sea/ocean dwelling creatures. However, there is also mountainous habitat that has snow, meaning it is high up and cold. This provides a habitat for even more species adapted to different environments.
Therefore, the island will be the most diverse.
Answer:
Explanation:
Mutation can cause a change in DNA to change in many ways.
Mutation is the sudden change in the genome of an organism that can be heritable from parent by their offspring.
Missense mutation - This occur when a base pair is substituted for by another leading to the formation of an entirely new amino acid.
Nonsense mutation - This occurs when a base pair is substituted for by another leading to the formation of a new amino acid. The new amino acid form therefore send a stop signal to the sequence of amino acid been built.
Insertion or deletion - Insertion mutation inserts new base pair into the sequence changing the number of the DNA base while deletion deletes a base pair changing the number of DNA base from the amino acid sequence.
