Answer:
Glaciers bring quantities of minerals beneficial to plants as the water runs off melting ice.
Explanation:
Glaciers are natural reservoirs of water and minerals that may persist to dry conditions during the summer season. Ice melting provides water and minerals during the warm season, which is therefore critical for plants living in dry summer environments. Moreover, it is well-known that the 'melt-water' (i.e., water released by the melting of glacial ice) also affects downstream stream water temperatures, creating a microhabitat that may be beneficial to the life of plant species.
We know that frequency of recombination is proportional with the distance between the genes on the chromosome. Therefore when the recombination rate is higher that means the distance between the genes on the chromosome is bigger. If the recombination rate is lower that means the genes are closer to each other on the chromosome. In this case the cross over rate is half the normal rate in the wild-type. That means that on the genetic map the distance between the two genes on the wild type will be twice bigger than the genes of the mutated Drosophila.
Answer:
If the type of food available changes, then the frequency of beak also changes.
Answer:
Coal
Explanation:
Coal is considered a nonrenewable resource, because it takes millions of years to form.
