In hydrangeas, color shows codominance. When a hydrangea has both the allele for lilac petals (L) and the allele for blue petals (B), its petals will be lilac & blue (LB). If you were to cross a lilac & blue hydrangea with a blue hydrangea, what would the parental cross look like?

Ll x LL

LL x BB

LB x BB

Ll x l

b. the carbon cycle ensures living things have a source of hydrogen

stimulus is a change in the environment that causes an organism to react. the response is the reaction to the stimulus. some examples of stimuli for zebras are drought, to many predators, and bad feeding grounds such as dead grass or plants. zebras respond to stimuli just like all other living organisms

ask your friends for what they got then copy it down if you don't have any friends which is fine than google it or pay the teacher

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
