The correct answer is A.
Water runoffs usually carry nutrients especially fertilizers from off the landscape and washed them into the wetlands and other water bodies. Phosphorus is a common ingredient that is present in all fertilizers. Phosphorus acts as a pollutant in these water bodies and put the organisms living in the water bodies at risk. High concentration of phosphorus causes rapid growth of plants in the wetlands and lead to depletion of oxygen leading to the death of organisms living in the wetlands.
Due to this occurrence, the Florida government has taken steps and enact several laws to ensure that the phosphorus pollution is arrested in order to preserve the wetlands.
Answer: Hello your question is incomplete below is the complete question
Let’s look at a different gene locus, we’ll call it B. The normal, wild type, the population was 100% BB. There are 150 Pakicetus in the population at present. Assume Charles had another mutation; this one at the B locus, to produce allele b. What is the gene frequency of allele b in the population if the population of Pakicetus reaches 100,000
answer : ≈ 1
Explanation:
<u>Determine the Gene frequency of allele b </u>
Population = 100,000
There are 150 Pakicetus in population i.e. 300 alleles at locus B
hence the frequency of b = 1/300 = 0.33%
Increase in population does not affect frequency of b ( HW equilibrium )
<em>therefore the Gene frequency of allele b </em>
= 0.33% * 0.33% * 100000 = 1.08
≈ 1
Groundwater is enclosed in aquifers. Groundwater
is found within a large range of rocks, but the most effective aquifers
are found in porous, open cavities, and permeable rocks. Aquifers can
contain salty, briny, and fresh water. Groundwater can exit the aquifer
by the pumping of a well, which is usually called discharge. The answer is aquifers.
Answer:
Plants produce oxygen gas and glucose molecule during the process of photosynthesis by absorbing radiation of the sun.
Explanation:
Photosynthesis is a process in which glucose and oxygen are produced by the combination of carbondioxide and water in the presence of sunlight. Carbondioxode is taken in the leaves through stomata and water is absorbed by the plant from the soil. When these two substances combine in the presence of sunlight produces glucose and oxygen.
