4.
Using the Quotient Rule, the derivative of y = (x + 3) / (x - 2) for x != 2 is:
1 / (x - 2)2
(2x + 1) / (x - 2)2
5 / (x - 2)2
-5 / (x - 2)2
5.
If f(x) = |x - 3|, the derivative f'(3) at x = 3:
Equals 0
Does not exist because the left-hand derivative (-1) does not equal the right-hand derivative (+1)
Equals -1
Equals 1
6.
Pure water reaches its maximum density (1.000 g/cm3 or 1000 kg/m3) at a temperature of:
-4.0 °C
25.0 °C
0.0 °C
4.0 °C
7.
Boyle's Law states that for a fixed mass of an ideal gas kept at constant temperature, the volume V is:
Directly proportional to absolute temperature
Independent of pressure changes
Inversely proportional to its absolute pressure P (P1 * V1 = P2 * V2)
Directly proportional to pressure
8.
Absolute zero temperature (0 Kelvin or -273.15 °C) is defined physically as the theoretical temperature at which:
All liquids solidify into glass
Atmospheric air completely combusts
Water reaches its maximum density
The volume and pressure of an ideal gas theoretically extrapolate to zero and translational molecular motion reaches its quantum minimum
9.
The pressure of a gas trapped inside an incandescent light bulb is 0.8 atm at room temperature (27 °C). When the bulb operates, the filament heats the gas to 327 °C at constant volume. The operational pressure is:
2.4 atm
0.96 atm
1.6 atm
1.2 atm
10.
The density of an ideal gas at temperature T and pressure P is rho. If the pressure is tripled and the absolute temperature is halved, the new density becomes:
3 rho
0.67 rho
6 rho (since rho is proportional to P / T)
1.5 rho
11.
The chemical formula of aluminum sulfate is correctly written as:
Al2(SO4)3
Al(SO4)3
Al3(SO4)2
AlSO4
12.
When examining a patient who suffers from severe weight loss, bulging eyes, rapid heart rate, and high temperature, the doctor diagnoses the condition as:
Exophthalmos caused by excessive secretion of the hormone thyroxine
Dwarfism
Diabetic urine
Myxedema
13.
In the secondary immune response upon exposure to the microbe for the second time, the response is characterized as:
Rely only on the first line of defense
Limited to non-specialized immunity
Slow and takes days
It is very rapid and produces huge amounts of antibodies thanks to memory cells, and the individual does not show symptoms of the disease
14.
The motile phase (motile zygote / ookinete) in the life cycle of Plasmodium malaria is characterized by:
Haploid group N
It secretes malaria toxin
It is diploid (2N) and penetrates the mosquito's stomach wall and turns into an egg sac
It attacks red blood cells
15.
DNA Repair Enzymes, which number approximately 20 enzymes, depend for their work on:
Heat irradiation of the cell
Production of lipoproteins
Destruction of the infected cell
The presence of a corresponding healthy template strip complementary to the damaged strip to guide its sequence in repair
16.
The thermal multiplex device (PCR - Polymerase Chain Reaction) depends on an enzyme that tolerates high temperatures called:
Taq polymerase enzyme
RNA polymerase enzyme
Amylase enzyme
Human DNA polymerase enzyme
