Most proteins in present-day mitochondria are made by cytoplasmic ribosomes from mRNA transcribed from nuclear genes. Can this fact be reconciled with the hypothesis described in the passage

The options are not given, here are the options.

A.Yes; the transfer of genes from symbionts to the eukaryotic nucleus could have occurred during the last billion years of evolution.

B. Yes; this difference from bacteria is unimportant, because the many similarities between bacteria and mitochondria provide sufficient evidence in favor of the hypothesis.

C. No; the fact that mitochondrial proteins are made in the cytoplasm is convincing evidence that mitochondria do not have a bacterial origin.

D. No; because bacteria can make all their own proteins and mitochondria cannot, this disproves the hypothesis.

The correct option is B.

Yes; this difference from bacteria is unimportant, because the many similarities between bacteria and mitochondria provide sufficient evidence in favor of the hypothesis

Explanation:

From the passage, the protein synthesis abilities of bacteria and Mitochondria was spelt out.

Bacteria are unicellular organisms and they are prokaryotic. Bacteria do not have membrane bound organelles like Mitochondria as compared to Eukaryotic organisms.

Mitochondrial and bacteria have certain similarities which include, mitochondria have cell membranes like bacteria and they have circular genome like bacteria.

The similarities shows that most most proteins in mitochondria are made by cytoplasmic ribosomes from mRNA transcribed from nuclear genes.

4.) metal

"-the movement of carbon from the nonliving environment into living things and back to the environment

-carbon is the essential component of proteins, fats, and carbohydrates (which make up all organisms)

-carbon exists in air, water, and living organisms

-producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis

-bacteria in the atmosphere cycles through the system in filtration units

-in cellular respiration, carbon is released back into the atmosphere as carbon dioxide

-some carbon is stored in limestone (forming one of the largest "carbon sinks" on earth)

-largest carbon reservoir on earth= limestone

-carbon stored in the bodies of organisms as fat, oils, or other molecules may be released into the soil or air when the organism dies

-this may form deposits of coal, oil, or natural gas (fossil fuels, which increased the atmospheric carbon dioxide)

-fossil fuels store carbon left over from bodies of organisms that died millions of years ago

-they are located in the surface of earth, deep within the earth and beneath the ocean floor."
