Answer:
genotype: 50% Yy 50% yy
phenotype: 50% yellow and 50% green
Explanation:
simply make a punnett square and cross the heter0zygous (Yy) and hom0zygous recessive (yy) between each other to get the genotypical results of Yy, yy, Yy, and yy. the phenotypical results are based on which color is dominant over which so Yy would be considered the dominant trait and that is yellow and yy is recessive and green. because you have two of each it is a 50% chance the pea plants offspring will be green and a 50% chance it will be yellow.
Answer:
CH4 + 2O2 -----> CO2 + 2H2O.
Explanation:
CH4 + 2O2 -----> CO2 + 2H2O is the chemical reaction of burning of fossil fuels. The main difference between biomass and fossil fuels is that biomass is biological material which can be derived from living whereas Fossil fuel such as coal, oil and gas are derived from biological material. Biomass is renewable because a new crop can be grown after each harvest, and biomass is a low carbon fuel. Biomass is renewable just like other renewable energy sources because both can be used again and again. The energy choices locally occurs according to the availability of energy resources in that locality.
