Plants and some types of archaea or bacteria use photosynthesis to create food.
Answer:
The correct answer would be divergent evolution showing by homologous organs.
Explanation:
In the illustration human arm, the flipper of the dolphin, wings of bat and forearm of frog are shown. All these four forelimbs have a different function, however, these forelimbs are having the same underlying anatomy.
The organs having basic structure and origin, but different functions are known as homologous organs. These organs point towards the same ancestor from these organisms evolved. They show a case of divergent evolution.
When related species become less similar in order to adapt and survive in different conditions, evolution is called divergent evolution.
Thus, these forelimbs provide evidence for divergent evolution.
Answer A seems like the best choice for this question. Just think about some of the synonyms for therefore—”hence,” “consequently,” and “thus.” Because the adverb therefore often plays the role of a conjunction, it's sometimes called a conjunctive adverb.
B isn’t the correct answer to this question because you use “On the other hand” to introduce two contrasting points, facts, or ways of looking at something.
C isn’t the correct answer because we are not comparing or contrasting anything in this sentence.
D isn’t the correct answer because “Especially” is used in a formal sentence example: She can't be sure she will win, especially at this early stage of the campaign.
It would be oxygen

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.
