A white rose cannot be produced in the G1 (first generation) of roses because the red rose will have a RR (R standing for red) allele combination. The pink rose will have a RW (R for red, W for white) <span>allele combination. When crossed all combinations will have at least one R allele, meaning that no roses (in the first generation) will have a WW allele combination. WW is the only allele combination that produces white roses.

Answer:
it burns easily and it gives energy
Explanation:
The calorific power of coals varies from 2,000 to 7,000 kcal/kg, from anthracite and coal to lignite and peat.
The dry distillation of coal produces four fractions: ammonia, tar, natural gas, and coke. The latter (hard, resistant, and porous) is used in the metallurgy of iron and steel (steel).
Lignite is used mainly in thermal power plants to obtain electrical energy from it. Peat is used as a domestic fuel.
