A diseased cell is no longer able to produce proteins. Which cell structure is most likely malfunctioning?

The ribosomes

Explanation:

Ribosomes are the organelle that produce proteins within eukaryotic and prokaryotic cells- taking information from the DNA in order to produce proteins.

Other organelles may be held responsible for the lack of protein production, but in this case it is most likely the ribosome.

1) gene flow

- it is described as the transfer of genes from one population to another population so that frequency of gene is increased.

-a zebra migrates to join a different herd of zebras.

2) natural selection

- a mechanism of evolutionary change in which individuals with advantageous traits survive and reproduce whereas the others ( those that can not adapt) eliminate from the population.

-competition for sunlight leads to taller trees.

3) mutation

- permanent change in the nucleotide sequence of dna ( genetic material) that could have harmful or useful consequences.

-the dna of a snake changes to make its venom stronger.

4) genetic drift - it is a random phenomenon ( that occurs by chance such as fire) that results in change in the gene frequency in a small population.    

-a grassfire randomly sweeps through a population of buffalo and kills most of the animals.
