1. How did we go from having a gametophyte to having a gametophyte with a sporophyte attached to it? 2. Ferns typically live in wet areas. Use your answer to question 1 to explain why this is the case.
3. Spores are the primary dispersal mechanism for seedless land plants. What adaptations does the fern have to increase the odds of one of its spores landing somewhere it will be able to successfully develop into a gametophyte?
4. How does the sporophyte of the fern compare to the sporophyte of the moss in terms of size, photosynthetic capability, and number of sporangia?

Melissa lives in a town called greendale. she discovers that when she lights a match and holds it near her kitchen faucet, the little flame grows into a larger fire. melissa is surprised because she thought the water would extinguish the flame rather than ignite it further. her mother tells her that the water might be contaminated with dissolved methane, a primary component in natural gas. melissa investigates the matter and finds that cases of methane contamination started shortly after a company began fracking for natural gas in the area. based on this information, which three statements are plausible consequences of fracking in greendale?

Which would be the most useful source of evidence to support mcneill's contention?

Which statements about the fluid mosaic structure of a membrane are correct? select the three correct statements.which statements about the fluid mosaic structure of a membrane are correct? select the three correct statements.the framework of a membrane is a bilayer of phospholipids with their hydrophilic heads facing the aqueous environment inside and outside of the cell and their hydrophobic tails clustered in the center.because membranes are fluid, membrane proteins and phospholipids can drift about in the membrane.the diverse proteins found in and attached to membranes perform many important functions.the kinky tails of some proteins keep the membrane fluid by preventing the component molecules from packing solidly together.membranes include a mosaic, or mix, of carbohydrates embedded in a phospholipid bilayer.
