fibroblst growth factor receptor 3 is a protein which responsible for formation of microfibrils and microtubules in cell division helpful for pulling the chromosomes during anaphase
because it helpful for production of melanin
due to its high mol.weight of the molecules
farmer is affraiding of insectivorus plants they are eating insects
it is nothing but enzyme which increase the rate of reaction
these are the primitive organisms contain nucleoid without nuclear membrane,membrane bound cell organelles are absent except 70s ribosomes.

follecular stimulating hormone stimulating the development of follecle from which ovule is released
due to the storage of hypnozoits and sporozoits stages of parasites(dorment stage)
all enzymes are made up of proteins but mot all proteins are enzymes because some proteins are structural proteins.
yes because non essential amino acids are synthesised in our body
male gamete is sperm cell produced from sperm mother cell and female gamete is oocyte produced from ovary.
usually flattend pea pod is dominent than the wrinkled pea pod so in f1 generation all are flattened pea pods where as in f2 generation homozygous flattend pea pods 25% and heterozygous flattend pea pods 50% and homozygous wrinkled pea pods 25% will come
BB (Homozygous dominent) 25% and Bb (heterozygous dominent) 50% and bb(homozygous recessive.so phenotypic ratio is 3:1 and genotypic ratio is 1:2:1
