Examine the following genetic sequences and determine which pair are the most similar based on their ed (evolutionary distances).species 1 = attggccattspecies 2 = attccggtttspecies 3 = tttggccattspecies 4 = att

Species 1 = ATTGGCCATT and Species 3 = TTTGGCCATT are the most similar.

Explanation:

Evolutionary distance (ED) is defined as the total number of substitutions of nucleotide in one site between two DNA sequences that are homologous. It is also referred to as the number of substitutions of amino acid in one site between two protein sequences that are homologous. Based on the definition of ED, the two most similar species are species 1 and 3.

answer; ///as energy flows through an ecosystem,energy (decreases) at each

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
