Circulatory system

1. No artery carries blood to the heart. Arteries carry blood away from the heart. Veins carry blood to the heart.
2. The largest artery is the aorta.

Excretory system

1. The earthworm excretes nitrogenous waste (such as urea and ammonia), water, and salts.
2. The excretory system for protozoa involves the contractile vacuole (for osmoregulation and waste removal) and diffusion across the cell membrane.
3. The excretory system for insects is the Malpighian tubules.

Living things

1. A bryophyte with a ribbon-like structure is a liverwort (e.g., Marchantia).
2. Snails belong to the phylum Mollusca (class Gastropoda).
3. The example of a non-vascular plant is:
   • II. Marchantia
4. The universal recipient blood type is AB positive (AB+).
5. The probability that the 4th child will be a girl is $\boxed{\frac{1}{2}}$ or $\boxed{50\%}$. Each birth is an independent event.
6. If parents both have sickle cell trait (heterozygous, HbAS), their children can have normal hemoglobin (HbAA), sickle cell trait (HbAS), or sickle cell disease (HbSS).
7. An example of a fungi disease is athlete's foot or ringworm.
8. Jean-Baptiste Lamarck postulated the acquired traits theory.
9. Secondary growth in older dicot roots occurs in the vascular cambium and cork cambium.
10. An example of secondary succession is forest regrowth after a wildfire or vegetation returning to an abandoned agricultural field.
11. The apex predator in an aquatic habitat varies, but examples include sharks, killer whales, or large tuna.
12. The primary vector for cholera transmission is contaminated water.
13. The intertidal zone (or littoral zone) has high tides.
