Answer the following question given this paragraph: A mature sporophyte fern has the familiar leafy fronds. The undersides of the leaves are dotted with clusters of sporangia. Sporangia produce spores that develop into tiny, heart-shaped gametophytes. Gametophytes have antheridia and archegonia. Antheridia produce sperm with many cilia; archegonia produce eggs. Fertilization occurs when sperm swim to an egg inside an archegonium. The resulting zygote develops into an embryo that becomes a new sporophyte plant. Then the cycle repeats. Q: Sporangia produce spores that develop into tiny, heart-shaped what? Choices: - cells - tubules - filaments - gametophytes A:
gametophytes

Answer the following question given this paragraph: Alkaliphiles are organisms that "love" bases. Bases are like the opposite of acids. Basic environments where archaeans are found include Mono Lake in California, pictured in Figure below . Mono Lake is the oldest lake in North America. The water is not only unusually basic. It's also saltier than the ocean. So archaeans that live in the water of Mono Lake must have adaptations to both salty and basic conditions. They are haloalkaliphiles. Q: What is the term for organisms that have adaptations to both salty and basic conditions? Choices: - salinophytes - sporozoans - heterophiles - haloalkaliphiles A:
haloalkaliphiles
