1. Where does human fertilization typically take place within the female reproductive system?
Answer: C
Fertilization—the fusion of a sperm cell with an ovum—normally takes place inside the Fallopian tube.
2. Which floral organ attracts insect pollinators using vibrant colors and scents?
Answer: B
Brightly colored petals attract insects and birds, encouraging them to visit the flower and transport pollen.
3. Which method of asexual reproduction is utilized by bread mold (Mucor) to spread?
Answer: B
Mucor produces light, microscopic spores inside sporangia that disperse through the air to colonize new food sources.
4. Which form of asexual reproduction involves an outgrowth developing on the parent organism before detaching?
Answer: B
Budding involves the growth of a small protrusion (bud) on the parent body (such as in yeast or Hydra) that eventually detaches as a new organism.
5. Which process describes the transfer of pollen grains from an anther to a sticky stigma?
Answer: B
Pollination is the mechanical or biological transfer of pollen from the male anther to the female stigma.
6. What is the correct biological sequence following successful fertilization in humans?
Answer: A
Fertilization yields a single-celled zygote, which divides into an embryo, implants and grows into a fetus, and is delivered as a baby.
7. What primary protective role is served by the fluid contained inside the amniotic sac?
Answer: B
Amniotic fluid acts as a protective shock absorber guarding the developing fetus against external pressure or bumps.
8. Which organ of a flower develops into a fruit after successful fertilization?
Answer: C
Following fertilization, the ovary matures into a fruit, while the ovules inside transform into seeds.
9. Why are the testes located within the scrotum outside the main abdominal cavity?
Answer: B
Sperm development requires a temperature about 1 to 2°C lower than normal body temperature, provided by the external placement of the scrotum.
10. Which artificial method of vegetative propagation involves growing plant tissue in a sterile nutrient culture under controlled conditions?
Answer: C
Tissue culture allows large numbers of identical plants to be propagated from tiny tissue samples cultured in sterile media.
