Mendel kept careful numerical data describing the results of his pea experiments. He knew that if alleles segregated randomly when forming gametes, mathematical probability should predict the outcome of the F2 generation. His true-breeding parent plants were homozygous, RR or rr. This cross resulted in an F1 generation of heterozygous plants, Rr. 1. What phenotypes would you predict in the F2 generation?

the correct option is option a

answer: substrate concentration. enzymes work best when there is a high enough substrate concentration for the reaction they catalyse.

the oldest known insects are believed to live around 400 millions ago as suggested by the fossil records.   some plants having woody stems also evolved during this time.

after the evolution of insects the first four legged species or the tetrapods evolved in shallow freshwater habitats from the intermediate species approximately 397 million years ago. the tetrapods went on conquering the land giving rise to amphibians, reptiles, mammals and birds.

the major split in tetrapods first occurred 340 million years ago branching off from amphibians.

363 million years ago when the carboniferous period began the insects started roaming on land and taking flights, following which the four limbed tetrapods adapted in the terrestrial habitat.

propane is burned to provide the heat in many cooking grills. the chemical reaction for this process is shown in the equation below.

c3h8 + 5o2 ? 3 co2 + 4h2o + energy

what are the products in this chemical reaction?

3co2 + 4h2o + energy
