Question: Answer the following question given this paragraph: Pollination occurs when pollen is transferred from a male to female cone. If sperm then travel from the pollen to an egg so fertilization can occur, a diploid zygote results. The zygote develops into an embryo within a seed, which forms from the ovule inside the female cone. If the seed germinates, it may grow into a mature sporophyte tree, which repeats the cycle. Q: If pollination occurs, what does the zygote develop into? Choices: - an ovum - a sperm - an egg - an embryo A:

Answer the following question given this paragraph: Most adults experience at least some hearing loss as they get older. The most common cause is exposure to loud sounds, which damage hair cells. The louder a sound is, the less exposure is needed for damage to occur. Even a single brief exposure to a sound louder than 115 decibels can cause hearing loss. Figure below shows the relationship between loudness, exposure time, and hearing loss. Q: Because it damages hair cells, what is the most cause of hearing loss in adults? Choices: - bacteria - ear wax - water in the ears - exposure to noise A:
exposure to noise
