12. Insects are considered to be beneficial because they are:
- A. Effective pollinators
- B. Sources of useful products and potential protein
- C. Biological control agents
- D. All of the above

- A. Conditioning
- B. Habituation
- C. Instrumental learning
- D. A and C

15. A certain insect usually becomes active each day at dusk. If kept in the dark all day, it will still become active around sunset even though it cannot see the sun. This behavior is an example of:
- A. Transverse orientation
- B. A circadian rhythm
- C. Diurnal behavior
- D. Exogenous entrainment

Answer :

Final answer:

The provided answers cover various aspects of biology, primarily focusing on insect behavior, fertilization processes in chickens, and physiological mechanisms like osmoregulation and negative feedback systems. Key definitions and examples provide clarity on each topic. Understanding these concepts is essential for grasping how organisms interact with their environment and regulate their internal systems.

Answers to the Questions

  1. 10. The site of fertilization in the chicken is C. Infundibulum. In chickens, fertilization occurs in the infundibulum, which is the upper part of the oviduct where the ovum meets the sperm.
  2. 11. The stage in the insect life cycle called the resting and inactive stage is C. The pupa stage. The pupa stage is characterized by a halt in feeding and decreased movement, as the insect undergoes metamorphosis.
  3. 12. Insects are considered beneficial because they are D. All of the above. They contribute to effective pollination, are sources of useful products (like honey), and serve as biological control agents for pests.
  4. 13. The behavior described is an example of B. Habituation. This describes how a female insect returns to her larval host plant based on instinct, even if she has not fed on it.
  5. 14. Behavior patterns that change drastically over the lifetime of an insect are probably A. Learned. Learned behaviors can adapt based on experience, while innate behaviors are more rigid.
  6. 15. The behavior of the insect becoming active around sunset is an example of B. A circadian rhythm. This refers to biological processes that cycle in a 24-hour period.
  7. 16. The correct order of terms in negative feedback to maintain homeostasis is C. 3, 2, 1, 5, 4. This means receptor (3) senses a stimulus (5) and sends information to the control center (1), which activates an effector (2) to create a response (4).
  8. 17. The mechanism of regulation of solutes and the loss and gain of water in humans is known as C. Osmoregulation. This process ensures the balance of fluids and electrolytes in the body, crucial for proper physiological functioning.
