How does the structure of the artery in its function?

Here are the solutions for the questions from the image: 10. How does the structure of the artery in its function? Arteries carry blood under high pressure from the heart to the rest of the body. To withstand this pressure and maintain blood flow, their walls must be thick, muscular, and elastic, allowing them to expand and recoil with each heartbeat. The correct option is B. Thick elastic muscular walls. 11. The diagram below represents a nephron. When does ultra-filtration occur? Ultra-filtration is the initial step of blood filtration in the kidney, occurring in the glomerulus, which is enclosed within Bowman's capsule. In the provided diagram of the nephron, the Bowman's capsule is labeled as '1'. The correct option is D. 1. 12. Where does gaseous exchange take place in the human respiratory system? Gaseous exchange, where oxygen enters the bloodstream and carbon dioxide leaves it, primarily occurs in the alveoli (tiny air sacs) within the lungs. The correct option is B. Alveoli. 13. Why is it that only 10% energy is transferred from one trophic level to another? According to the 10% rule, only about 10% of the energy from one trophic level is transferred to the next. This is because the majority of the energy consumed by an organism is used for its own metabolic processes, such as respiration, movement, and maintaining body temperature, rather than being stored as biomass that can be passed on. The correct option is D. Energy is used in metabolic processes. 14. Which structure in a bird plays a role in food storage? The crop in birds is a muscular pouch located near the esophagus that serves as a temporary storage organ for food before it moves to other digestive organs. The correct option is A. Crop. 15. Below is the diagram of a bean seed: During germination, water enters the seed through the: The micropyle is a small pore or opening in the seed coat of a bean seed. During germination, this pore is the primary entry point for water absorption, which is crucial for initiating the germination process. The correct option is B. Micropyle. 16. The diagram below is that of spirogyra: Which labelled part enables it to carry out autotrophic nutrition? Autotrophic nutrition involves producing one's own food, typically through photosynthesis. In Spirogyra, photosynthesis takes place in the chloroplasts, which are clearly labeled in the diagram. The correct option is A. Chloroplast. 17. The diagram below is that of the mammalian brain. Which of the labelled parts control reasoning and intelligence? The cerebrum is the largest part of the mammalian brain and is responsible for higher-level functions such as reasoning, intelligence, memory, voluntary actions, and sensory perception. The correct option is C. Cerebrum. Send me the next one 📸
