.What industry contributes to wetland loss in Louisiana?
"The swamps and marshes of coastal Louisiana are among the Nation's most fragile and valuable wetlands, vital not only to recreational and agricultural interests but also the State's more than $1 billion per year seafood industry.What part of Louisiana is most in danger from land loss?
Dozens of reports show the highest rate of land loss occurred in areas with the heaviest amount of oil and gas extraction and canal dredging, Marshall says. According to some studies, the oil and gas industry is responsible for anywhere between 36 to 60 percent of the loss.
The correct answer is b. Release of short-chain fatty acids.
The intestinal microflora is complex ecosystem which contains over 400 bacterial species.That microflora is capable of fermenting indigestible carbohydrates (dietary fiber) to short-chain fatty acids such as acetate, propionate, and butyrate.
Lactic acid produced by fermentation causes the sour taste.
Answer:
The genotype for the pink flower is Rr and the genotype for the white flower
is rr. This would lead to a 50% chance of the offspring having a phenotype of pink.
Explanation:
A mutation that involves one or a few nucleotides is called
a) mutagen
b) inversion
c) point mutation
d) translocation
Answer:
c) point mutation
Explanation:
When only one or a few nucleotides of a gene are changed by mutation, this is called a point mutation. A point mutation can add one additional nucleotide to the wild type gene or may delete or substitute a nucleotide from it. For example, if a wild type gene sequence is "ATATATATA", then the addition of "C" at the position 4 will change it into "ATACTATATA". This addition of new nucleotide is called point mutation since only one nucleotide is added to the gene. Point mutations can cause serious genetic disorders such as sickle cell anemia.
