Effects on Waterways
Fertilizers contain large amounts of nitrogen and phosphorus. When these chemicals runoff agricultural fields into waterways, they can lead to accelerated growth of aquatic plants. Nutrients from fertilizer runoff encourages the growth of nuisance algae through the process of eutrophication.
The answer to this question is "Dendritic Cells". In addition to m cells, the "Dendritic cells" in the epithelium can capture pathogens directly from the lumen of the gut without disturbing other cells and processes in the epithelium of the epithelial layer.
Answer:
a) Some island populations will have fixed one allele, and other populations will have fixed the other allele.
Explanation:
The founder population for each island is heterozygous for the locus. The absence of any migration and mutation would result in no gene flow or the introduction of new alleles of the locus. Over several generations, one or the other allele will be fixed in the populations depending on the adaptive features imparted by each under the different conditions present on these different islands. Genetic drift may also work on these small founder populations to randomly fix one or the other allele.
The answer is B. <span>White oaks are grouped in the genus Quercus. </span>
According to binomial nomenclature, a formal system of naming species, a name of species is composed of two parts. The first word indicates the organism's genus classification, the second word indicates the species within a genus. So, the first word Quercus indicates the genus in both cases, the second word alba or rubra indicates species within the genus Quercus.
A. is not the right answer because alba indicates species name, not genus name.
C. is not the right answer because white oaks and red oaks are different species, but the same genus.
D. is not the right answer because Quercus is not species but genus.
I think its A , Oil is a nonrenewable resource so its not D
