Which is the largest cell?

A. Egg of Ostrich

B. Nerve cell

C. Bacteria

D. Granule cell

Solution: A

Cell is the basic unit of life. The smallest cell is in bacteria which varies from 0.1 to 0.5 micrometres. The largest cell is the egg of the ostrich.

In humans, the smallest cell is granule cell of Cerebellum which varies between 4 to 4.5 micrometres. The longest cell in human body is nerve cell. The largest cell in the human body is Ovum. 

Hence, option (A) is correct.

What is the chemical formula of Silica?

  A. NaAlO 2 B. H 2 O C. Al 2 O 3 D. SiO 2      Solution: D The Chemical formula for Silica is SiO2. Silica is the common name for Silicon Dioxide. It is commonly found in quartz. SiO2 forms 3-dimensional network solids in which each silicon atom is covalently bonded in a tetrahedral manner to 4 oxygen atoms.  Hence, option (D) is correct.

Which of the following enzymes is used in the stabilization of rice bran oil? (RRB NTPC CBT-2 9 May 2022 Shift 1 Paper)

A. Hydrolase B. Catalase C. Lipase D. Cellulase Solution: C Lipase enzymes are used in the stabilisation of rice bran oil. Stabilisation of rice bran is important as it can become rancid during storage.  Enzymes are deactivated via proper stabilisation and maximum nutrients are retained. Thermal treatment is the most common method to stabilize rice bran. Rice bran is a by-product of milled rice. It contains many micronutrients like proteins, carbohydrates, oil, tocopherols, phytosterols, etc.   Hence, option (C) is correct.

Water falls from a height of 60 m at the rate of 15 kg/s to operate a turbine. The losses due to frictional force are 10% of the input energy. How much power is generated by the turbine ? (g=10 m/s2) ( NEET Exam 2021-Physics Section)

(1) 10.2 kW  (2) 8.1 kW  (3) 12.3 kW  (4) 7.0 kW Solution: (2) In the above question, height is given as 60 metres.  mass per unit time= 15 kg/s g= 10m/s 2 Loss due to frictional force is given as 10% of energy i.e. only 90% input is used to generate energy. P= mgh/t*0.9 P=10 x 60 x 15 x 0.9 = 8.1 kW Hence, option (2) is correct.  Read NCERT notes on Force and NCERT Notes on Friction .
