[#726] pH for culturing fungi is
Correct Answer
(A) 6 - 6.5
Explanation
Solution: pH for culturing fungi is 6 - 6.5. pH impacts the composition of microbes and nutrient availability in soil. Organic sources of the elements are dependent on the activity of bacteria and fungi to release them in the soil. Fungi may be cultured on a variety of media types. These media can be either solid or liquid depending on the experiment to be performed. Most fungi grow in medium containing a high carbohydrate source, nitrogen source, a pH of 6 - 6.5, and a temperature range from 15° - 37°C.
[#727] In an organism utilising carbohydrates as its source of energy anerobically, the R.Q. is likely
Correct Answer
(D) Infinity
Explanation
Solution: In an organism utilizing carbohydrates as its source of energy anaerobically, the R.Q. is likely Infinity.
[#728] The number of functional plant nutrient is
Correct Answer
(A) 16
Explanation
Solution: The number of functional plant nutrients is 16. These are essential plant nutrients required by plants for the proper functioning and growth of the plant. These nutrients are Nitrogen, phosphorus, potassium, calcium, magnesium and Sulphur as macronutrients and iron, manganese, boron, molybdenum, copper, zinc, chlorine and cobalt as micronutrients.
[#729] Endospore is formed in
Correct Answer
(A) Gram +ve bacteria
Explanation
Solution: Endospore is formed in Gram +ve bacteria. An endospore is a dormant, tough, and non-reproductive structure produced by some bacteria in the phylum Bacillota. The name "endospore" is suggestive of a spore or seed-like form, but it is not a true spore. It is a stripped-down, dormant form to which the bacterium can reduce itself. Endospore formation is usually triggered by a lack of nutrients and usually occurs in Gram-positive bacteria.
[#730] Major role of minor elements inside living organisms is to act as
Correct Answer
(A) Binder of cell structure
Explanation
Solution: The major role of minor elements inside living organisms is to act as Binder of cell structure. Minor elements or microelements are usually only needed in trace amounts for cell functioning. Microelements in humans play several physiological functions including the synthesis of enzymes, hormones and other substances, helping to regulate growth, development and functioning of the immune and reproductive systems.
