Mutualism is a long lasting, mutually beneficial interaction among organisms. Which of the following relationships best reflects mutualism? 1) A starfish provides a safe place for sea worms to reside; the starfish receives nothing in return.

2)Reef corals build a hard protective skeleton that algae live in; the algae provide energy to the coral through photosynthesis.

3)Butterflylarvae lay their eggs on jaguars and consume blood and nutrients from the jaguars.
4) Galapagos tortoises eat all the branches of cactus plants; the plant is harmed and sometimes dies.

Aspecies has evolved an asexual mode of reproduction by having offspring develop from unfertilized eggs. which of the following will be true of this species' response to natural selection? there will be more deaths from natural selection because there is no mutation. there will be less genetic variation from recombination and a risk of not adapting quickly to environmental change. the species will increase in numbers because genetic variation is increased. the species will compensate for loss of genetic variation by hybridizing with other species. there will be fewer deaths from natural selection because sexual recombination always leads to extinction.
