I decided to take
the high-school MCAS tests by doing a little bit each day when I get home from work, instead of doing the crossword puzzle.
I just finished the Biology test. Got 89% of the multiple choice correct. Things I learned:
- The large intestine removes water from undigested waste (I guessed "absorbs nutrients")
- A 'zygote' is formed when a sperm cell's nucleus fuses with an egg cell's nucleus
- A 'secondary consumer' is a thing (like a chipmunk) that eats something (like a grasshopper) that eats something else (like an 'Idaho fescue'), not something (like bacteria) that decomposes animals' bodies.
- Legumes have nitrogen-fixing bacteria on their roots
