Why do organisms make one type of protein for a feature while other organisms make two?

It may mean that the two proteins evolve in slightly different directions, so that one version works better in one set of conditions and the other under different conditions.

Please note that the cost to the organism of making two proteins instead of one is minimal. Basically, it involves adding one coding gene to the tens of thousands of genes that are already there (assuming that the sum of the amounts of the two proteins is about the same as the amount of the original one protein).

Different versions of the same protein may also be made by differential splicing of the mRNA, or by the many mechanisms of post-translational modification.

Explanation:

im lazy so imma leave this out

For every gene, there may be several possible versions. Different genes carry instructions for making different proteins. If the gene copies are heterozygous, two types of protein are produced, if the gene copies are h0m0zyg0us, one type of protein is produced.

Explanation:

interphase   is the cell cycle stage in which the cell acquires nutrients, creates and uses proteins and other molecules and starts the process of cell division by replicating the dna. it is the longest stage in the eukaryote cell cycle.

the following   can go wrong during interphase:   a base pair could be mismatched during the duplication process causing a mutation.   correct answer: c

explanation:

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
