PLEASE HELP I AM GIVING 15 POINTSSS ONLY IF YOU ARE CORRECT I WILL GIVE BRAINLIEST Guppies living in a stream have a variety of spot patterns, some of which provide good camouflage against the stones in the streambed and others of which make them stand out against the background, allowing potential mates to see them more easily. If a predator that hunted by sight were introduced to the stream, what would be the most likely long-term consequence for the guppy population?

A) The number of guppies in the population would decline, although most of the remaining ones would be uncamouflaged.

B) The guppy population would devise a mutation that allowed the camouflaged guppies to find mates by scent or sound.

C) The guppy population would die out since none of the guppies would be able to find mates.

D) The number of camouflaged guppies in the population would increase while the number of successful matings decreased.

Archeologists have discovered three sites showing conclusive evidence for the mastery of fire in tanzania, from a period slightly after the time that homo habilis was present in africa. these sites clearly were founded by homo erectus, the descendent species of homo habilis that migrated north, out of africa and into asia. homo erectus was known to have mastered fire, from ample evidence at sites in asia. there is no reason to attribute mastery of fire to homo ergaster, the descendent species of homo habilis that remained in africa.which of the following is an assumption on which the argument depends? (a) before their migration, homo erectus occupied african territory as far south as tanzania.(b) the strain of migration provided the selective pressure motivating homo erectus‘ mastery of fire.(c) homo ergaster would not have derived as much benefit from the mastery of fire as did homo erectus.(d) homo ergaster inherited all cultural knowledge from homo habilis, a species that did not have mastery of fire.(e) homo ergaster did not occupy regions as far south as tanzania until well after the time of these three sites.
