The first answer because if you "multiply" the T's and the t's together they come out with TT, Tt, and tt
PS: This would be a lot easier to explain if I could show you how
Answer:
bolus,chyme and feces
Explanation:
The enzyme in the saliva digests starch to maltose. The tongue rolls the food into small round masses called boluses, then pushes the bolus into the pharynx for swallowing.
The stomach wall is made up of thick circular and longitudinal muscle layers. These muscles contract and relax producing movement that aids in the mixing of the contents of the stomach. This mixing is known as churning and results in the formation of a fluid called chyme.
The remaining semi-solid waste material is then passed to the rectum where it is stored temporarily and eventually eliminated from the body as feces through the anus as the sphincter muscles relax.
Answer:
Bacteriocins
Explanation:
Bacteriocins are the toxic proteins that are synthesized and released by the bacteria that are the part of the normal microbiota. These proteins have a molecular weight of 900 to 5800 Daltons. The bacterial species that release the bacteriocins are resistant against it.
Secretion of bacteriocins is an adaptive feature as these toxic proteins do not allow the growth of other strains of the same species or related species. One of the examples of bacteriocins are colicins that are released by <em>Escherichia coli</em>.
I think its B but I'm not sure .. sorry
