Phages are a positive use of viruses
Answer:
Mutations increase genetic variation and the potential for individuals to differ
Explanation:
Mutations can result in an organism having a new allele. When that organism produces offspring their offspring are most likely to inherit the allele created from the mutation which could potentially lead to genetic variation.
Most important are the many striking similarities between prokaryotes (like bacteria) and mitochondria: Membranes — Mitochondria have their own cell membranes, just like a prokaryotic cell does. DNA — Each mitochondrion has its own circular DNA genome, like a bacteria's genome, but much smaller.

Answer:
The students are asked, how do the embryos provide evidence for organic evolution.
Explanation:
The embryos of different vertebrate groups have been found to have similar morphological features during the early stages of development. This similarity suggests a common ancestry. The closer the resemblance between the embryos in early stages the closer the phylogenetic relationship of the organisms.
