Answer:
I would say C. but i don't think it will be
Answer:
Replicate itself into the cell host
Explanation:
Visus is made from a protein capsule and inside a fragment of RNA. Sometimes they also have some feet of filament to get attached to the cellular membrane.
Once attached, the virus injects its RNA into the cytoplasm and travels to the nucleus and insert this fragment of RNA into the cell DNA and start making copies of itself.
When the cell is full of virus, the membrane breaks and releases all the new virus to the neighbor cells, and the process starts again.
Answer:
B. Use the polymerase chain reaction (PCR) to make multiple copies of the DNA.
Explanation:
The scientist is to analyze a small sample of DNA, the most useful step to start this would be first the use of polymerase chain reaction to make various copies of that DNA sample. PCR is essential and quick process that gives a lot of copies within few hours. It uses the sample or target DNA, according to which the primers are designed. Taq polymerase and DNA polymerase are also used in the process, it consist of various cycles in which copies are made. There are three basic steps 'Denaturation', 'annealing', and 'extension'.
Birds migrating in the winter would be a behavioral adaptation. The rest of the adaptations would be structural or physiological because they are controlled by mutations in the DNA. <span />
Answer:
The answer to your question is: letter C. two are prokaryotes and four eukaryotes
Explanation:
A two are eukaryotes, and four are prokaryotes. This answer is wrong because animalia, plantae, fungi and protista are eukaryotes.
B four are plants, and two are animals. This answer is wrong because only one kingdom is plants (plantae).
C two are prokaryotes, and four are eukaryotes. This answer is right there are two prokaryotes (eubacteria and archaebacteria) and the others are eukaryotes.
D four are bacteria, and two are eukarya. This answer is wrong there are only 2 bacteria not 4.
