Answer:
Option 3 and 4 are most likely correct
Explanation:
<em>Option 3</em>: We know that area 1 would contain heavy streaking and not single colonies. Therefore, if the loop crosses area 3 and enters area 1, it will definitely result in heavy streaking again.
<em>Option 4</em>: We always need to sterilize properly the loop when streaking in different areas. If we don't do it, it is possible that the loop contains a lot of bacteria that would be streaked again.
Options 1 and 2 are incorrect because, according to question, there is a uniform growth but no isolated colonies. So, contamination or mixed culture would not produce uniform growth streaking rather mixed with other bacterial types.
Answer:
The main sequence stretching from the upper left (hot, luminous stars) to the bottom right (cool, faint stars) dominates the HR diagram. It is here that stars spend about 90% of their lives burning hydrogen into helium in their cores. Main sequence stars have a Morgan-Keenan luminosity class labelled V.
Explanation:
The building blocks of protein are C. AMINO ACIDS.
Amino acids are made up of a center carbon atom bound positively to a charged amino group and a negatively charged carboxyl group and a side chain.
The primary structure of a protein is the sequence of an amino acids that are attached together by a peptide bond
The secondary structure of a protein, the polypeptide is folded through the mechanisms of amino acids rotating around bonds folding into a helix or a pleated sheet structure and stabilized by a hydrogen bond.
Pupillary response is a physiological response that varies the size of the pupil, via the optic and oculomotor cranial nerve. Involuntary reflex reaction to exposure or inexposure to light—in low light conditions a dilated pupil lets more light into the eye. :)
The similarities between the low-light seedlings and moderate-light seedlings are the amount of chlorophyll until 12 hours and the differences suddenly increase after this period.
<h3>What is photosynthesis rate?</h3>
The photosynthesis rate is the amount of photosynthetic products (i.e., glucose) that generates by a plant in a given unit of time, which depends on the amount of chlorophyll.
In this case, low-light seedlings and moderate-light seedlings produce amount of chlorophyll at a similar rate until 12 hours, while the maximized value for moderate-light seedlings and low-light seedlings is 48 hours.
In conclusion, the similarities between the low-light seedlings and moderate-light seedlings are the amount of chlorophyll until 12 hours and the differences suddenly increase after this period.
