Answer:

Sodium bicarbonate acted as a pH buffer in Solution 2.

Explanation:

One the other hand, sodium bicarbonate is alkaline in nature and has pH of 8.4. When an acid is added to a solution containing sodium bicarbonate, it will act as a pH buffer for acid and neutralize the acidic effect.

Other options are incorrect because there are no hormones added neither they will be produced or released during the reaction.

Also, lower initial pH of the solution 1 will not help to increase the pH after addition of acid.

Neither change in temeprature can change the pH.

how many dna molecules would there be after four rounds of pcr if the initial reaction mixture contained two molecules?
Marat540 [252]
  1. Answer: 32 molecules of DNA would be after four PCR if the initial reaction mixture contained two molecules
  • After 'n' rounds of the polymerase chain reaction, it is feasible to produce 2 n DNA molecules from a single DNA template molecule (PCR). Therefore, 2 to the power 4  = 16 DNA molecules will be produced after 4 PCR cycles
  • If two molecules are doubled four times, 32 DNA molecules are created.

Explanation:

The PCR method is what?

The highly sensitive PCR method enables quick DNA amplification of a particular section. Using visual methods based on size and charge, PCR may detect and identify gene sequences by producing billions of copies of a certain DNA fragment or gene.

What does a PCR have to accomplish?

A given DNA segment can be quickly multiplied (amplified) into millions or billions of copies using the polymerase chain reaction (abbreviated PCR), allowing for more in-depth analysis.

What are the three main PCR steps?

For any DNA synthesis reaction, there are only three easy stages that must be completed: First, the template is denaturated into single strands. Next, primers are annealed to each original strand to synthesise new DNA strands. Finally, the new DNA strands are extended from the primers.

What factors do biologists consider when placing organisms into different groups?
harkovskaia [24]

Answer:Morphology and Physiology

Explanation:Morphology studies the form,structure and features of an organism this could include the shape,height,color etc while physiology help study the underlaying factor that gives rise to the ways its functions.

This two are key for a Biology to group an organism for when the morphology is know it is possible to classify such organism.
