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

After collecting specimens from many areas of the world, Darwin noted the similarities in them. He discovered that new kinds of species could gradually grow into new ones over years.

Answer:
<u>The woodpeckers wouldn't have homes/shelters to keep themselves safe so they would slowly die out.</u>
Answer 2:
I'm pretty sure you can also say, <u>they would have to adapt to living in a new species of tree</u>

An organism has 28 pairs of chromosomes in its diploid somatic cells. How many chromosomes are in its gametes?
diploid = 2n, haploid = n
2n = 28 pairs = 28×2 = 56, n = 28
gametes are haploid = n = 28 total chromosomes
