18) Yeast cells divide, producing more new yeast cells.

Reproduction

19) When examining a leaf under a microscope, one sees that is it composed of many units similar to the units that make up other living things.

Cells

21) All giraffe’s necks are longer today, than when giraffes first evolved because having longer necks has allowed to them reach leaves on trees that other animals cannot reach to eat.
