Four bands appear in gel electrophoresis. Gel electrophoresis is an experimental method used to separate mixtures of DNA, RNA, or proteins by molecular size.
DNA is negatively charged, so when a current is applied to the gel, the DNA migrates towards the positively charged electrode. Fragments are ordered by size because short DNA strands migrate through the gel faster than long strands. There are some basic steps for performing gel electrophoresis outlined below. 1) pour the gel, 2) prepare the sample, 3) load the gel, 4) run the gel (expose it to an electric field), 5) stain the gel. Gel electrophoresis is a technique for separating biomolecules by size. Separation of these molecules is achieved by placing them in a small pore gel and creating an electric field across the gel

The answer is B. Hope this helps!
Reasoning: Brown Algae and Dinoflagellates are both on the same branch, unlike other answers.
Answer:
Diffusion of solutes in liquids is very important in many industrial processes, especially in such separation operations as
1) liquid–liquid extraction or solvent extraction,
2) gas absorption
3) distillation
4) Diffusion is important to cells because it allows them to gain the useful substances they require to obtain energy and grow
5)and lets them get rid of waste products.
Answer:
Image result for individual living thing
An organism is any individual living thing. It is easy to recognize a living thing, but not so easy to define it. Animals and plants are organisms, obviously. Organisms are a biotic, or living, part of the environment.
