1.
An aqueous solution of titanium(IV) chloride (TiCl4) is diamagnetic and colorless because:
Chlorine ions quench all magnetic dipoles
The Ti4+ ion has an electronic configuration of [Ar] 3d0, devoid of unpaired d-electrons
It absorbs all visible wavelengths of light
Titanium is an alkali earth metal
2.

Methyl orange
Phenolphthalein
Litmus solution
Bromothymol blue

5000 N
2 N
2500 N
50,000 N
6.
In a hydraulic press, if the radius of the large piston is 4 times that of the small piston, the mechanical advantage is:
4
8
16
2
7.
An air bubble released from the bottom of a deep lake expands in volume as it rises towards the surface because:
The hydrostatic pressure decreases as depth decreases, allowing the trapped air to expand according to Boyle's law
The bubble absorbs water molecules into its gas phase
Atmospheric pressure increases at the surface
The water temperature at the surface is near absolute zero
8.
Phenolphthalein indicator cannot distinguish between an acidic solution and a neutral solution because:
It is colorless in both
It precipitates in both
It is blue in both
It is red in both
9.
What is the direct physiological effect of injecting a healthy person with an excessive dose of the hormone insulin?
Increased urine secretion
A severe drop in blood glucose levels (hypoglycemia) and hypoglycemic coma
A sharp increase in blood sugar
Uric acid accumulation
10.
The apple is considered a false fruit from a morphological and anatomical perspective because:
The cup leaves become greasy
The edible, fatty part that is lubricated by food is the takht, not the ovary of the flower
It is made without seeds
Produced from a hermaphrodite flower
11.
The genetic code is characterized as universal because:
It is found in the nucleus only
It does not change with mutations
The same codons code for the same amino acids in all organisms from bacteria to humans, confirming the common origin of life
It consists of only two letters
12.
