Punnett squares can also be used to predict genotypes of the parents. A guinea pig with short hair is crossed to one that has long hair. Over a period of years, a scientist keeps records of the offspring and finds that 44 of them have curly hair and 46 of them have straight hairBased on this data, what are the genotypes of the parents:

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.

Which level of taxonomy has the fewest organisms?

What is a functional group? a group of organic molecules that work together to speed up reactions a group of organs in the body that work together to perform a certain function a group of atoms bonded to carbon that determines how the molecule will react a group of living things that are made up of organic compounds
