1.
The Ideal Gas Law combining all empirical gas relationships is mathematically formulated as:
P * V = n * R * T
P / V = n * R * T
P * V = m * g * h
P * T = n * R * V
2.
According to the 2026/2027 Egyptian STEM biology syllabus, what is the exact scientific deduction regarding: Chargaff's Rules of DNA Base Pairing?
Adenine bonds with Guanine via three hydrogen bonds
Uracil replaces Thymine in the double helix of nuclear DNA
The percentage of %A + %T always equals 50% in all organisms
In any double-stranded DNA molecule, the percentage of Adenine equals Thymine (%A = %T) and Guanine equals Cytosine (%G = %C), with purines equaling pyrimidines
3.
Which of the following conditions leads to increased secretion of parathormone from the parathyroid glands?
Excessive vitamin D excess
Low phosphate
High blood calcium level
Low level of ionized calcium in blood plasma
4.
Combined contraceptive pills are considered an effective method because they:
The fallopian tubes close mechanically
Placental abruption
It kills sperm
It contains synthetic hormones similar to estrogen and progesterone that inhibit the secretion of FSH and LH from the pituitary, thus preventing the maturation of eggs and the occurrence of ovulation.
5.
A synthetic chromosome mutation that occurs when a piece of chromosome separates, wraps around itself at an angle of 180 degrees, and then rejoins in the same position is called:
Deletion mutation
Repetition mutation
Transmission mutation
Inversion mutation
