3. How did the scientists studying cells during the development of cell theory (Schleiden, Schwann, Virchow, Van Leeuwenhoek, and
Hooke) contribute to the birth of cell theory?

the denominator has a very specific role.

hello

answer: collecting information/data

reason: the student is going around and asking people questions to collect data

i hope this

the correct answer is sex-linked recessive.

i just took the test

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.
