Correct Answer: A 8,388,608

Explanation

According to the law of independent assortment, there are 2n combinations where chromosomes can assort into different gametes. So where n is the haploid number, you get 223=8,388,608. There are 8,388,608 possible combinations of chromosomes when assorting into gametes.

Correct Answer: B. binding agents for roofing materials

Explanation

Pitch and asphalt (often spelled as 'asphalt') are indeed residual products from the fractional distillation of petroleum. They are heavy, viscous, and often black or dark brown substances known for their waterproofing and adhesive properties.

Let's evaluate the options:

• A. protective coatings for road surfaces: Asphalt is the primary binder in asphalt concrete, which is widely used for road surfaces. It acts as both a binder for the aggregate and contributes to the protective and waterproof nature of the road. While this is a major use for asphalt, pitch is less commonly used for primary road surfacing compared to asphalt.

• B. binding agents for roofing materials: Both pitch (especially coal tar pitch, but also petroleum pitch) and asphalt are extensively used in roofing. They act as binding agents for felt, gravel, or other roofing components, and provide excellent waterproofing. This application is common to both substances mentioned.

• C. organic solvents: Solvents are typically more volatile liquids used to dissolve other substances. Pitch and asphalt are heavy, viscous substances, and are not generally used as solvents themselves.

• D. catalysts for cracking: Catalysts are substances that speed up chemical reactions. Cracking is the process of breaking down large hydrocarbon molecules into smaller ones. Pitch and asphalt are very large, complex hydrocarbon molecules themselves and are not used as catalysts; in fact, they are often the residual products left *after* various cracking processes have extracted lighter fractions.

Considering that the question mentions *both* pitch and asphalt, B. binding agents for roofing materials is an excellent fit as both substances are widely used for this purpose. While asphalt is also a dominant material for road surfaces (Option A), option B applies strongly to both pitch and asphalt.

The final answer is B

Explanation

a. Location of industry may be defined as the sitting or establishment of a firm or industry in a particular place. An industry may be established either by individuals or government, either for economic or political reasons.

bi. Cement producing industries should be located close to sources of raw materials to reduce cost of transportation. Perishable goods like fruits, palm oil industries, etc should be located near their raw materials.

bii. There should be ready market for the products of any industry to be sited in a place. Fragile goods like glass, bulky goods like cement and other perishable goods should be located near the market. Such industries located or directed towards the market are called market-oriented industries.

biii. Government can encourage the location of industries through certain policies like: direct participation in setting up of industries. Creation of industrial zones in the country, provision of infrastructures like electricity, pipe-borne water, roads and tele-communications.

c.

- It encourages development: the growth of industries leads to an increase in production of goods and services.

- Emergence of subsidiary firms: as major firms concentrate in one area, other subsidiary service firms that assist those major firms in the production of goods usually emerge.

- Generation of employment: the concentration of many industries in an area leads to the creation of many job opportunities.
