Biology helping with medical research and treatment
The right answer to this question is option C. the traits acted upon natural selection were genes.
At the time Charles Darwin developed the evolution theory, there wasn't a single study about genes in all science scenery, that could be explained by the lack of technology to study them and even to know they existed in the first place.
So, his theory was basically talking about adaptation, if an organism can't survive a specific environment, he'll probably die until another generation comes in and this one can survive in this environment, passing their genes to the next ones. The lack of information was the knowledge about the genes we have today, that's why most scientists take only the new Darwin theory, that includes the study of genes.
Endoplasmic reticulum is an organelle within a cell. It is divided into smooth and rough endoplasmic reticulum. Smooth endoplasmic reticulum is involved in synthesis and transportation of of lipids while rough endoplasmic reticulum contains ribosomes which are responsible for synthesis of proteins, therefore rough ER is involved in transportation of proteins. A few proteins are synthesized in the mitochondria and the plastids. Therefore, proteins synthesized elsewhere other than the rough ER are the Mitochondrial proteins
Well If the Salmon die from lack of food from polution or something, and other animals benafit from the nutrience they carry. the rest of the ecosystem might parish, i hope that helped im not sure what was wanted
Most vaccines will cause your body to produce cells that in turn produce thier own antibodies in order to fight off future illnesses later on whereas antibiotics provide a quick dosage of antibodies with no prolonged immunity and in fact kill off alot of the good bacteria in your body
