Answer:
The right words to fill the blank are DNA POLYMERASE ENZYME.
Explanation:
DNA polymerase chain is a method used in molecular biology to produce abundant copies of specific DNA segments. The process is catalyzed by an enzyme called DNA polymerase. The DNA polymerase enzyme is usually isolated from bacteria, which live in hot spring. One good example of such bacteria is Thermus aquaticus. The DNA polymerase isolated from this particular bacterium is usually preferred because it is heat stable and produce DNA strands at faster rates compared to natural DNA polymerase.
Answer:
<em>The correct option is A) if the research uses anonymous questionnaires</em>
Explanation:
For research studies, it is always important that the consent of the participants be taken if they are to be mentioned in the research. Without the consent of a person, a researcher cannot use anything related to that person in his research. However, in scenarios where you have to keep the data anonymous and just depict the results, consent is not necessary. However, one should recognize that apart from anonymous studies, not taking consent of the participants is unethical.
Answer: C. The orchids receive water and oxygen from the fungi, while the fungi receive food and minerals from the orchids.
Mycorrhizal association refers to the mutualistic symbiotic relationship between a fungi and roots of vascular plants. In this type association both partners are benefited.
The plant roots are unable to take nutrients which are chemically or physically immobilized in the soil. The mycelium of the mycorrhizal fungus helps to avail those nutrients to the plants. Thus plants are able to obtain phosphates and iron through these fungi. These fungi also, increase the water absorption capacity of plants. In return the fungi receives the direct access of carbohydrates like glucose and sucrose. These carbohydrates translocate from leaves to roots, from there fungi receives these carbohydrates as food source.
The plant orchid and fungi of phyllum basidiomycota form mycorrhizal association, which is a mutalistic association. Thus, the orchids receive water and oxygen from the fungi, while the fungi receive food and minerals from the orchids.
