Task1:

What is the molecular mass of a gene, if one strand of DNA molecule encodes the polypeptide molecule with molecular mass is 4500g/mol? Molecular mass of one amino acid is 100g/mol, molecular mass of one nucleotide is 345g/mol.

Tas 2. Define and characterize all stages of transcription.

which are post-impressionist paintings? check all that apply?

explanation:

post-impressionism is a predominantly french art movement that developed roughly between 1886 and 1905, from the last impressionist exhibition to the birth of fauvism. post-impressionism emerged as a reaction against impressionists' concern for the naturalistic depiction of light and color.

hope this have a good day

increase soil erosion                                             reduce soil erosion

cattle grazing                                                         hydroseeding

deforestation                                                         contour plowing

                                                                                planting vegetation

plant roots basically hold the top soil

together and stop soil erosion because

in such situation top soil is not removed

during flood but cattle grazing causes

soil erosion because cattle consume the

grasses and herbs and top soil is exposed.

same situation occurs because of

deforestation, the trees and plants are cut

down to expose top soil which causes soil

erosion
