Algae and Cyanobacteria could mean life is flourishing and is a good food source for some fish in moderation- but if there's a lot of fertilizer runoff, they can grow too quickly and be counterproductive for the environment
Answer:
Unavailability of food decrease their population.
Explanation:
The population of Galapagos Finches decreases because of unavailability of food. Galapagos Finches feeds on a specific insects whose population decreases on that Island that leads to the death of the Galapagos Finches and they decrease in number. Positive population growth occurs only if more food is available to the Finches or they adapt another food item for themselves which fulfill their need of food.
Histone deacetylase is responsible for removing the acetyl group from the histone 3 lysine 9 residue. Remember that deacetylation is one step in converting euchromatin to heterochromatin. Because euchromatin is transcriptionally active (transcriptional machinery is able to reach gene of interest), and blocking histone deacetylase activity would result in an the DNA remaining as euchromatin, we would expect to see an increase in transcriptional activity.
So there’s your answer: An increase in transcriptional activity.
<span>Nitrogen fixation
This process creates organic compounds, including ammonium, that contribute to the growth of a plant in much the way fertilizer does. Many plants have evolved to facilitate nitrogen fixing bacteria in their roots as to promote production of these organic compounds when the soil quality is poor or lacking in these bacteria.</span>
This is because the melanocytes are located in the stratum basale. Lighter-skinned people usually have low basal levels, and exposure to UV radiation causes an increase which makes skin darker.
