Answer:

The process of photosynthesis is complex. Sunlight energy is converted into chemical energy by using chlorophyll, which is what gives plants their green color.

I need help with my biology homework I need to answer this question a student is given a tube containing a liquid nutrient mediu
kifflom [539]
This is the day to day problem of a medical microbiology laboratory: the "tube containing a liquid nutrient medium" in the real world could, for example, represent blood culture bottles (aerobic or anaerobic). The basic process is as follows: a loop is first flamed to ensure sterility and then used to transfer a small portion of bacterial-laden liquid media to the agar medium by streaking it across the surface of a sterile petri dish. The dish is then covered, inverted, and placed in an appropriate incubator. When colonies begin to form on the surface of the agar plate, individual colonies can be taken up using the sterile loop for analysis or further propagation. The assumption is that a single colony represents growth from a single bacterium.

Viktor [21]

Answer:

Option (a).

Explanation:

A reporter gene may be defined as the gene that are attached to the regulatory sequences to find the gene of the interest in research. The reporter gene can be easily identifiable.

The recombinant cells can be identified by the fusion of the reporter gene and the protein. Here, the  green fluorescent protein acts as the reporter gene that can be easily identified and fuses with the protein that will produce a single the protein. The protein shows the green fluorescent that contains the yeast nuclei.

Thus, the correct answer is option (a).
