Climate change is affecting the chemistry of the world's oceans. In particular, the ocean water is becoming more acidic. For purple sea urchins, this poses problems as their calcium-based exoskeletons may dissolve in acidic conditions. In a certain population of purple sea urchins, some individuals possess a trait that makes their exterior more resistant to acid. If global climate change continues (as predicted) to make ocean water more acidic, how might this population of purple sea urchins evolve in response to this increased acidification? A:Purple sea urchins with a trait of having shorter, more flexible spines would become more common. B:Purple sea urchins with a trait that make their exoskeletons less resistant to dissolving in acidic water would become more common. C:Purple sea urchins with a trait that make their exoskeletons resistant to dissolving in acidic water would become more common. D:Purple sea urchins with a trait of having longer, more rigid spines would become more common.

Climate change is affecting the chemistry of the world's oceans. In particular, the ocean water is
becoming more acidic. For purple sea urchins, this poses problems as their calcium-based
exoskeletons may dissolve in acidic conditions. In a certain population of purple sea urchins, some
individuals possess a trait that makes their exterior more resistant to acid.
If global climate change continues (as predicted) to make ocean water more acidic, how might this
population of purple sea urchins evolve in response to this increased acidification?
A:Purple sea urchins with a trait of having shorter, more flexible spines would become more common.
B:Purple sea urchins with a trait that make their exoskeletons less resistant to dissolving in acidic
water would become more common.
C:Purple sea urchins with a trait that make their exoskeletons resistant to dissolving in acidic water
would become more common.
D:Purple sea urchins with a trait of having longer, more rigid spines would become more common.
