Mutations are structural changes to genes that may affect proteins. Shins are beneficial meaning they help the organism. Some mutations are harmful because they reduce the organism ability to survive or reproduce other mutations neither help nor harm the organism. These are called neutral mutations. The three images below show organism with mutations.
Which of these mutations would be considered neutral Mutations?

The meselson-stahl experiment demonstrated that dna replication is semiconservative. in the figure, semiconservative replication is illustrated by

Salmonella typhimurium is a food-borne bacterial pathogen that can cause severe gastrointestinal disease. salmonella is often phagocytosed by macrophages that normally destroy bacterial pathogens, but this bacterium is somehow able to prevent the complete maturation of phagolysosomes. salmonella is able to tolerate the low ph of phagolysosomes, and in fact responds to the drop in ph by secreting toxins that interfere with other cellular responses. which of the following differences would you expect to contribute to the survival of a bacterium within an salmonella-containing phagosome, compared to a healthy phagolysosome? decreased activity of acid hydrolases increased activity of acid hydrolases decreased import of h+ ions increased import of h+ ions my guess is decreased activity of acid hydrolases but i'm not sure.

What is the role of the phospholipid belayer in cellular transport in living cells
