[#376] For quick and accurate detection of viruses can be done by
Correct Answer

(D) All of these

Explanation

Solution: Quick and accurate detection of viruses can be done by ELISA, HADAS and IEM. The enzyme-linked immunosorbent assay (ELISA), whose sensitivity and practicability have rendered it the most common primary screening assay. The most sensitive IEM technique in viral diagnosis is solid phase IEM (SPIEM). IEM mainly relies on high-affinity virus-specific antibodies or other specific ligands, e.g. lectins that may be used in different ways.

[#377] Premature leaf fall is caused due to the deficiency of
Correct Answer

(C) Nitrogen

Explanation

Solution: Premature leaf fall is caused due to the deficiency of nitrogen. Premature leaf drop is prevalent in the landscape due to dry weather. Plants are drought damaged by leaf desiccation, slowing of photosynthesis, and slowing of growth. Leaves wilt or roll, turn off colour and drop. Symptoms of nitrogen deficiencies in plants are general chlorosis of the leaves, which is when leaves turn pale green and leaves cup upwards quite severely in deficient plants.

Correct Answer

(C) Super phosphate is added to the compost during its preparation

Explanation

Solution: Super digested compost is called so because Super phosphate is added to the compost during its preparation. Super digested Compost is an environmentally natural fertilizer, which is a mixture of decomposed organic matter and is used to improve soil structure and provide nutrients, it acts as a fertilizer and can also be used as a mulch to suppress weeds and retain moisture. And on the addition of superphosphate fertilizer make it more nutritive and effective to be used.

[#380] Nutrients which affect growing tips most are Ca and
Correct Answer

(D) B

Explanation

Solution: The nutrients which affect growing tips most are Ca and B. Calcium is an essential plant nutrient. It plays an extremely important role in producing plant tissues and it enables plants to grow better. Calcium is responsible for holding together the cell walls of plants. B is one of the essential nutrients for the optimum growth, development, yield, and quality of crops. It performs many important functions in plants and is mainly involved in cell wall synthesis and structural integration.
