Red hair is a single-base mutation of the mc1r gene. if your mom has red hair, can you end up inheriting that trait as well?

question 5 options:

yes, red hair is a dominant trait which means the next generation will likely end up with it.

yes, if your mom has red hair, the mutation of her dna can be passed from her dna to yours during meiosis.

no, mutations do not pass from one generation to the next.

no, red hair is a result of a mutagen attacking dna, so it only affects a single person.

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.
