1. What is the biggest problem associated with the introduction of the invasive species, Zebra Mussels, in the Great Lakes? They increase the purity of the lake water.
They produce fatter and faster growing salmon.
They consume small amounts of algae.
They clog up factory intake plpes.

i think its control and coordinate because im pretty sure thats what tissue does and the joints are what control movement and then your skeletal/ bones provides portection. hope that .

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.
