Answer: D. His conclusion is flawed because he did not test the students to see if their bodies contained metal arsenic.
Explanation:
According to the given situation, student has tested seven different areas around the school to determine the presence of arsenic in the soil and also found the presence of arsenic in the school system. But has not studied the presence of arsenic in the students to support the fact that the school students are also affected by arsenic. So, conclusions based on the presence of arsenic in the soil and the system is inconclusive for the present study.
Answer: we classify organisms to group living beings who share the same characteristics or who have common attributes
Explanation: So, since the late '60s and based on the proposal of the researcher Robert Whittaker, most biologists group living beings into 5 large groups called Kingdoms, based mainly on three characteristics:
* type of cell,
* number of cells in each organism and
* the way of obtaining energy.
As a result, we could have 5 kingdoms; and these kingdoms are:
Monera, represented by the microorganisms of prokaryotic type known colloquially as "bacteria"
-Fungi, represented by mushrooms
-Plantae, the kingdom of the plants
-Animalia, the kingdom of the animals, and
-Protist, a very diverse group of organisms of eukaryotic type.

Answer:
The correct answer is <em>A molecule consisting of three phosphate groups, ribose, and adenine.</em>
Explanation:
ATP means adenosine triphosphate, and it is a molecule which has a very important role in energy transfer in the cells. As its name says, it is composed by:
- adenine: a purine base, which is also a component of nucleic acids.
- ribose: a 5-carbon sugar (in contrast to deoxyribose, ribose has a -OH group in place of a -H group in carbon 2)
- three phosphate groups
Notice that adenine bonded to the ribose is called adenosine.
Answer:
In this case, the biology graduate have to select species-specific genes and then identify if they were expressed in RNA-seq data
Explanation:
By RNA-seq it is possible to identify mRNAs specifically expressed between species since homologous species-specific genes may show single nucleotide polymorphisms (SNPs) among alleles with a biased gene expression
The correct answer is an Arachnid.
