Imagine that a biologist discovers a new species of green algae that has a cuticle-like waxy coating and some rudimentary structures for containing and protecting the gametes. These clues suggest that the new species is very similar to the direct ancestors of the land plants. Where would such a find most likely occur?
A. a lakeshore or marsh with water levels that rise and fall frequently
B. mats of algae that hang near the ocean's surface, similar to the floating seaweed mats seen in the Sargasso Sea
C. in a deep, cold mountain lake with a very stable water level
D. a deep-sea hydrothermal vent community

B. mats of algae that hang near the ocean's surface, similar to the floating seaweed mats seen in the Sargasso Sea

Explanation:

i think

the two answers are a, the population of birds with large beaks will increase on the island, and c, the trait for large beaks will be passed on to future generations through natural selection. the reason for that is because if the birds that have beaks developed for eating small seeds lose all of their food, they will go hungry and eventually starve because they physically cannot eat the large seeds, therefore making the population of large beaked birds higher. also, if the trait of large beaks are dominant on the island over small beaks, then over time the large beaked birds will reproduce more and more, while the smaller beaked birds will reproduce less and less because they can't survive with the food provided. that leads to the trait of small beaks disappearing and the trait of large beaks taking over the island.
