Answer:
The activity factor was modified. Ambulating indicates that the person is active. Even small activities require energy. So, people who can walk around and aren’t bedridden expend more calories than people who need to be on bedrest all day. Also, when the stress factor was changed to severe infection, the caloric requirement increased. This increase is probably because the immune system requires more energy to fight off the infection

Answer: reproduction
Explanation: the process by which an organism produces its offspring is called reproduction.
In step 2: Denaturation of the double-strand occurs.
In step 3: Annealing of the primer to the single strands.
In step 4: Extension or elongation takes place in this step.
Explanation:
In the PCR program an enzyme Taq Polymerase is used because it can withstand high temperature without altering its functions.
PCR is required for the amplification of DNA into multiple copies for experimental purpose. The artificial environment is created to form new DNA molecules from the sample in question.
The first step in replication is the opening of the double helix which is done by temperature treatment in PCR. The temperature would be 90 degrees for some 30 sec to two minutes.
The next step of primer annealing would be done at 52 degrees, this is the primer melting temperature.
The elongation of the DNA strand to be synthesized will take place at 72 degrees as Taq Polymerase can withstand that temperature.
Nearly one million copies of DNA will be made after 30 cycles of PCR.
PCR products can be stored at 4 degrees for some two months.
Answer:
The Rock is picture is Felsic.
Explanation:
Rhyolites are volcanic rocks that are igneous. The main component of these rocks is Silica and based on silica content they are termed as Mafic, Felsic, Intermediate and ultramafic. Felsic rocks have the highest silica content (more than or approximately 65%) and are lighter in color than other rocks. Mafic, ultramafic and intermediate rocks contain less content of Silica. They have high content of magnesium and mostly are of dark color.
