Cells that are infected, damaged, or have reached the end of their functional life span often undergo "programmed cell death." this controlled cell suicide is called apoptosis. select the appropriate description of this event on a cell's life cycle. cells that are infected, damaged, or have reached the end of their functional life span often undergo "programmed cell death." this controlled cell suicide is called apoptosis. select the appropriate description of this event on a cell's life cycle. each cell organelle has protein signals that initiate the breakdown of the organelle's components which leads to cell death. during apoptosis, dying cells leak out their contents including digestive enzymes that also destroy healthy cells. apoptosis is regulated by cell surface receptors that signal when a cell has reached its density-dependent limits. during apoptosis, cellular agents chop up the dna

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.
