A detective finds a miniscule spot of blood on a murder suspect’s shirt. What method would the police lab be expected to use to
WARRIOR [948]

Answer:

Polymerase chain reaction (PCR)

Explanation:

Polymerase chain reaction (PCR) is a method by which a target DNA fragment is amplified to produce millions of copies. In PCR, the Taq polymerase enzyme uses nucleotides and primers to replicate a small DNA segment <em>in vitro</em> and produces two DNA molecules. The newly formed DNA molecules are denatured by heating to facilitate their replication to produce four double-stranded DNA molecules. In this way, the number of DNA molecules is doubled in each cycle. Therefore, the small amount of DNA obtained from the minuscule spot of blood on a murder suspect’s shirt can be amplified using PCR.

Most fungi grow best at pH<br> a. 1<br> b. 5<br> c. 7 <br> d. 9<br> e. 14
scZoUnD [109]

Answer: pH 5 Acidic environment.

Explanation:

The fungi grows best in the acidic environment, this is because the fungi grows in a moist, warm and darker environment.

The fungus grows at lower pH. When the fungal species was grown in the laboratory conditions then under low pH, the fungal species grow more properly.

Hence, the best environment for the growth of fungus is pH 5.

Lorico [155]

Answer:

The population suffered a genetic bottleneck, which decreased genetic variation and thereby randomly increasing the frequency of harmful alleles

Explanation:

A population bottleneck, also known as genetic bottleneck, can be defined as a drastic reduction in the size of a population, which may be caused by anthropic activity and/or environmental phenomena (e.g., earthquakes, famines, fires, droughts, etc). A genetic bottleneck leads to a reduction in genetic variability within a population. Moreover, the genetic drifit caused by a genetic bottleneck can also increase the frequency of harmful alleles/mutations (it is due to the random sampling of individuals), thereby increasing the frequency of deleterious alleles/mutations in the population.
