Blank 1: Mechanical

Blank 2: teeth

Blank 3: Chemical

Blank 4: saliva

Explanation:

The above are correct.

Mechanical digestion refers to the physical break down of food particles by the teeth. This process involves grinding, breaking, masticating and tearing of food substances with the teeth. This is done in order to make the food substances smaller for chemical digestion.

The chemical digestion further breaks the smaller food particles into absorbable particles. This is carried out by some enzymes found in the saliva. These enzymes are secreted in the digestive tract and it then breaks the chemical bond holding food particles together.

Therefore, mechanical digestion is done by the teeth while chemical digestion is done by the saliva.

Answer from: Quest

when alex falls for the charming new boy at school, cole -- a handsome, funny, sports star who adores her - she can't believe she's finally found her soul who truly loves and understands her.

at first, alex is blissfully happy. sure, cole seems a little jealous of her relationship with her close friend zack, but what guy would want his girlfriend spending all her time with another boy? as the months pass, though, alex can no longer ignore cole's small put-downs, pinches, or increasingly violent threats.

as alex struggles to come to terms with the sweet boyfriend she fell in love with and the boyfriend whose "love" she no longer recognizes, she is forced to choose -- between her "true love" and herself.

Read the following excerpt from "the city without us" by alan weisman: almost every other compound in nature contracts when frozen, but h20 (water) molecules do the opposite, organizing themselves into elegant hexagonal crystals that take up about 9 percent more space than they did when sloshing around in a liquid state. pretty six-sided crystals suggest snowflakes so gossamer it's hard to conceive of them pushing apart slabs of sidewalk. which statement best describes the effect of the metaphor on the excerpt's meaning? o a. it likens h2o molecules to hexagonal crystals, which are actually larger than people imagine. o b. it makes the frozen crystals seem like friends to the city to contrast with what a deceitful foe they are. o c. it compares the sloshing liquid to a river of water able to push apart the sidewalk o d. it compares the frozen crystals to delicately lacy snowflakes having an unexpected strength (apex)
