I WILL MARK AS BRAINLEST Anton Van Leeuwenhoek created microscopes that could magnify objects 10 times
better than anyone else at his time. In fact, his methods of grinding glass lenses were
so precise, it would be 150 years before anyone outdid his work. Imagine, though,
that microscopes never existed. What parts of the Cell Theory would we still be able
to figure out? Why?

a few examples of ethical concerns involving genetically engineering of humans include

-privacy of genetically tested people

- potential side effects

-long term effects

the cell cycle is the final answer! : )

i might be wrong but i think its a. let me know if i’m right and have a good rest of your day!

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.
