(solutions)|| latest update 2025/26
Which organelle is responsible for packaging and transporting proteins in the cell? -
CORRECTANSWER golgi apparatus
The Golgi apparatus modifies, sorts, and packages proteins for transport.
What is the complementary DNA strand for the sequence ATCGGA? -
CORRECTANSWER TAGCCT
Explanation: DNA pairing rules are A-T and C-G.
Which blood vessels carry oxygenated blood away from the heart? -
CORRECTANSWER arteries
Explanation: Arteries carry oxygenated blood from the heart to the body, except the
pulmonary artery.
Which organ is primarily responsible for nutrient absorption? -CORRECTANSWER
small intestine
absorbs nutrients through villi
, Which of the following is a product of photosynthesis? -CORRECTANSWER
Explanation: Photosynthesis converts carbon dioxide and water into glucose and
oxygen.
what are the building blocks of DNA -CORRECTANSWER nucleotides
Explanation: DNA is composed of nucleotides, each consisting of a sugar, a phosphate
group, and a nitrogenous base.
In humans, brown eyes (B) are dominant over blue eyes (b). A person with Bb genotype
has children with another person who is Bb. -CORRECTANSWER 25%
Explanation: A Bb x Bb cross gives a 1:2:1 ratio of genotypes (BB, Bb, bb), so the
probability of blue eyes (bb) is 25%.
Scenario: After eating a protein-rich meal, enzymes in the stomach and small intestine
break the proteins down into smaller molecules.
Question: What is the end product of protein digestion? -CORRECTANSWER amino
acids
Scenario: A person accidentally touches a hot surface and immediately pulls their hand
away.
Question: What type of response is this? -CORRECTANSWER reflex
