You're welcome. :)
DNA is negatively charged, therefore, when an electric current is applied to the gel, DNA will migrate towards the positively charged electrode.
Answer:
Homologies - phenotypic and genetic similarities due to shared ancestry
Analogies (homoplastic) - similarities between two species due to convergent evolution instead of descent from a common ancestor with the same trait
In general, organisms that share very similar morphologies or similar DNA sequences are likely to be more closely related than organisms with vastly different structures or sequences. In some cases, however, the morphological divergence between related species can be great and their genetic divergence small (or vice versa).
(plants very different, bc diverged 50 mil years ago)
If internal anatomy, physiology, and reproductive systems are very dissimilar, probably analogous.
The more elements that are similar in two complex structures, the more likely it is that the structures evolved from a common ancestor. If genes in two organisms share many portions of their nucleotide sequences, it is likely that the genes are homologous.:

Answer:
c. The founder of the modern environmental movement and author of Silent Spring is Rachel Carson
d. Deciduous trees such as most pines do not lose their leaves/foliage in winter.
Explanation:
Yes, Rachel Carson is the founder of the modern environmental movement as well as author of Silent Spring. She was an American marine biologist, author, and conservationist which started the modern environmental movement in order to save the environment form pollution. Yes, the Deciduous trees such as most pines do not lose their leaves/foliage in winter, they only lose those leaves that are too old. They are considered as evergreen plants.
