Some animals have an organ called the gizzard. The gizzard is muscular and helps to crush up hard food. Earthworms and many birds, including chickens, have gizzards. Chickens swallow small rocks that help the gizzard to grind up food. Did plant-eating dinosaurs have gizzards too? No one has found an actual dinosaur gizzard, but they have found small piles of round rocks inside dinosaurs’ ribcages.
Based on its function, the gizzard is part of the *blank*

Consider a culture medium on which only gram-positive organisms such as staphylococcus aureus colonies can grow due to an elevated nacl level. a yellow halo surrounds the growth, indicating the bacterium fermented a sugar in the medium, decreasing the ph as a result and changing the color of a ph indicator chemical. this type of medium would be referred to as a differential and enrichment culture.
