- A wire of resistance \(R\) is cut into 8 equal pieces. From these pieces, two equivalent resistances are made by adding four of these together in parallel. Then these two are added in series. The net effective resistance of the combination is:

- An oxygen cylinder of volume 30 litre has 18.20 moles of oxygen. After some oxygen is withdrawn from the cylinder, its gauge pressure drops to 11 atmospheric pressure at temperature \(27^\circ\)C. The mass of the oxygen withdrawn from the cylinder is nearly equal to: [Given, \(R = \frac{100}{12} \text{ J mol}^{-1} \text{K}^{-1}\), and molecular mass of \(O_2 = 32 \text{ g/mol}\), 1 atm pressure = \(1.01 \times 10^5 \text{ N/m}^2\)]

- Given below are two statements:
Statement I: Fig fruit is a non-vegetarian fruit as it has enclosed fig wasps in it.
Statement II: Fig wasp and fig tree exhibit a mutual relationship as the fig wasp completes its life cycle in the fig fruit and the fig fruit gets pollinated by the fig wasp. The current passing through the battery in the given circuit, is:

Three identical heat conducting rods are connected in series as shown in the figure. The rods on the sides have thermal conductivity 2K while that in the middle has thermal conductivity K. The left end of the combination is maintained at temperature 3T and the right end at T. The rods are thermally insulated from outside. In steady state, temperature at the left junction is \(T_1\) and that at the right junction is \(T_2\). The ratio \(T_1 / T_2\) is

Strategies For Enhancement in Food Production
Animal Husbandry
The raising and breeding of livestock are known as animal husbandry. Dairy farm management and fisheries are also included under animal husbandry and responsible for the selection of good breeds for better yield, maintaining a well-ventilated house and proper cleanliness and hygiene, and regulating proper disposal of waste.

Animal Breeding
The practice of raising a group of animals belonging to a common species. Inbreeding and outbreeding are the two types of animal breeding.
- Animals of superior male and female breed are made to mate for 4 to 6 generations. According to Mendel's experiment, true-breeding species or pure lines are created by Inbreeding which results in homozygosity.
- The breeding involving animals that are not related is known as outbreeding.
- Bee-keeping: The rearing of bees for the production of honey and beeswax is known as apiculture. One of the most common species of the honey bee is Apis indica. Beeswax is used to prepare polish, cosmetics, etc.
- Fisheries: Cultivation or breeding of aquatic flora and fauna for a commercial purpose is known as aquaculture. Fish and fish products for consumption are known as pisciculture.
Plant Breeding
In order to get rid of nutrient deficiency diseases, crops need to have a specific nutrient value besides disease resistance, pest resistance, and high yield capacity. There are many strategies for enhancing food production through plant breeding.
- Somatic Hybrids
- Totipotency
- Biofortification
Plant Breeding for Disease Resistance
Plant Breeding for Pest Resistance
Plant Breeding for Improved Food Quality
Single-Cell Protein
One of the ways to meet the growing demand of nutrients in plants and animals is a single-cell protein which is biomass that is rich in protein. microbes are produced on an industrial scale to get single-cell protein.
