Answer:
It’s impossible to know what would happen
Explanation:
If contaminated water is pumped form an aquifer, cleaned and pumped back, it would be impossible to know what would happen unless the source of the contaminant is known.
<u>If the source of the contaminant is known</u> and removed before the water is pumped back into the acquifer, the water would be clean and stay clean provided that all the water was initially pumped off. If the source of the contaminant is not known, it would be difficult to predict what would happen.
This liquid substance most probably be a member of the group of lipids. Liquids which do not dissolve in water are called hydrophobic substances. Nonpolar substances exhibit this effect. Lipids are a class of large molecules or macromolecules which are hydrophobic. Lipids include cholesterol, fat, and phospholipids.
Answer:
Option A, Pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction
Explanation:
Genetics variation allows as organism to evolve in a way to be able to cope up with the existing or changing environmental condition. Now, a Pantala flavescens undergoes sexual reproduction, thus only this creature has the ability among all the given organism to evolve genetically and be able to survive in this environment. All the remaining organisms reproduce asexually and hence there is no variation with in them and hence it would be difficult for these organisms to cope up with changing environment.
Hence, option A is correct.
Variation, Heritability, competition, and different survival.
The correct answer is "Phylum Urochordata: xi = 25; yi = 77".
The table presented in this exercise can be used as a tool to examine any connection between the microRNA (miRNA) diversity and the morphological complexity in a phylum. The Xi column represents the average number of miRNAs in a phylum, while the Yi column represents the average number of cell types in that phylum. The eight observation of this table refers to the data obtained from the phylum Urochordata.
MicroRNAs are small non-coding RNAs which regulate gene expression post-transcriptionally. They are used as phylogenetic markers as they have a very low rate of evolution. Also, they are very useful because it has been shown that phyla with very high levels of morphological innovation have high numbers of miRNA concentration.
