He tells her that often scientists do not favor pyramid of biomass because obtaining biomass requires advanced technology
The option C is correct.
Explanation:
The pyramid of biomass is the measure of the amount of biomass of living organisms present at every trophic level or unit area.
The biomass of pyramid is often not preferred by scientist because calculating the biomass is a tedious process.
It requires the heating of dead organism at high temperatures until a dry mass with constant value is obtained.
Although for biomass the size of the organism is taken into account but obtaining biomass requires advance technology.
The rate of biomass increase in organism in growth period is also tedious to measure.
Answer:
Purebred can be described as organisms that result from true-breeding. True breeding occurs parents who have a homozygous genotype are crossed so that the offspring produced might be similar to them. The alleles of the desired genes will be the same in the parents which will breed and produce similar alleles in their offsprings.
However, the phenomenon of pure breeding limits the gene pool and genetic variety becomes limited by such methods.
C is the awnser i hope this helped >_<
They both have a nucleus along with other complex membrane bound organelles.
