Why are biofuels derived from plants?
Lemur [1.5K]

Answer:

Biofuels are renewable fuels that are produced from biomass, organisms that were formed and stopped living a short time ago. The energy in the biofuels is called bioenergy. The major constituents of biomass are cellulose, lignin, starch and sugar, but many plants also contain other organic compounds that are beneficial for energy recovery from the material due to their physical structure and chemical composition. The difference between biofuels and fossil fuels is that fossil fuels take millions of years for new formation while new biomass for biofuels is constantly being formed. This means that biofuels can usually be considered carbon neutral as the carbon dioxide emitted during combustion is constantly bound to new biomass in a closed cycle.

True [87]

Answer:

Gene: The hereditary material made up of alleles.

Alleles: The alternative forms of a gene.

Dominant: An allele or trait that masks the effect of recessive allele or trait.

Recessive: An allele or trait that gets suppressed by the dominant allele or trait.

genotype: The genome of a particular organism of the genes which make up an organism.

phenotype: The physical traits or characteristics of an organism.

test- cross: A cross in which the dominant and the recessive trait offsprings are crossed to depict whether the dominant organism is homozygous or heterozygous.

law of independent assortment: Alleles of different genes get assorted independently into gametes.

law of segregation: allele pairs segregate during gamete formation and unite at the time of fertilization.

product rule: Independent evens can be calculated by multiplying the independent probabilities.

Addition rule: The probability which shows that one event would occur in a mutually exclusive event.

co-dominant: When the dominant and the recessive trait occur and the organism shows both the characteristics of the dominant and the recessive trait.

incomplete dominance: when the dominant trait is not fully dominant over the recessive trait. As a result, individuals are produced which show neither the dominant or the recessive trait. A new trait is developed in them.
