Answer:
Polymerase chain reaction machine
Primers
Petri dishes
Test tubes
Pipettes
DNA Polymerase
Free nucleotides
The organism to be identified
Explanation:
To identify the genetic makeup of an unknown organism, the nucleotide sequences fond in the Deoxyribonucleotide (DNA) of a known organism is matched to the DNA of some known organisms. If there is a certain degree of sameness in most of the matched parts, then the unknown organism can be said to be related to the known organism. This is a comparative study.
To carry out this identification, items used include; primers, the PCR machine, test tubes, DNA polymerase, free nucleotides, etc.
Answer:
D) Habitats for animals.
Explanation:
It depends what the question means when it says 'the changing of the rivers'. I took it as the rivers are changing size and becoming more spread out. In that case, I chose habitats.
The more water there is, the more habitat there is for sea life.
All in all, the correct answer is D).
The type of learning that the young sea otter used to be able to perform this task is social learning.
This means that the young otter learned what it is supposed to do from its surroundings - and what is surrounding it is its society of other otters. It is social learning because the otter didn't learn on its own that it needs to break open shells in order to eat what is inside, but rather it saw what the other otters were doing and thus learned it.
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
