The correct option is B.
The Linnaeus' taxonomic classification of organisms categories all living organisms into seven different groups, which are: species, genus, family, order, class, phylum and kingdom. The smallest group is the specie while the largest group is the kingdom. The kingdom is divided into two, the animal kingdom and the plant kingdom. The kingdom is the larges and most inclusive of Linnaeus taxonomy; the animal kingdom is made up of all animals while the plant kingdom is made up of all plants.
importance of a probe
in hybridization process, molecular biologist label a short fragment of DNA or RNA, usually 10-1000 bases long tagged with a radioactive or fluorescent molecules. this fragment is usually referred to as hybridization probe.probe important both in southern and northern blotting processed because it is used to identify a certain sequence of DNA or RNA in a pool several sequences that have been obtained using nuclease.
process of labeling DNA sequence with a probe
after the DNA strand has been cut into several fragments using enzyme DNA nuclease, the fragments are separated using gel electrophoresis and then denatured using hcl to obtain strands. the single strand are then transferred to nylon membrane that has positive charge. the next step is where probes come in. to detect the DNA sequence of interest the nylon membrane is treated with solution containing tagged probes. since the probes have complementary sequence to the target sequence, it bind to that DNA sequence and detected later using X-ray film.
Answer:
Good record keeping promotes both ac countability and integrity in research. Good re cords are complete, accurate and understandable to others. Records of research activities should be kept in sufficient detail to allow another scientist skilled in the art to repeat the work and obtain the same results
Explanation:
Answer:
Magnetic Declination
Explanation:
Magnetic declination, or magnetic variation, is the horizontal plane's angle between magnetic north and true north. This angle varies depending on the position on the Earth's surface and changes over time.
Answer:
No
Explanation:
Some are ocean, lakes, coral reef, swamps, coves, etc. They each have different characteristics. A ocean is bigger, and contains salt water. A lake, on the other hand, is smaller than an ocean, and has fresh water.
