16. Phenotype - The phenotype of an organism is the outward appearance of it. The traits seen are a product of the genes, however the phenotype and genotype of an organism may vary, such as a heterozygous haired person may look like a homozygous person but is really note. This example can be applied to the tomato. For example, tomatoes can be bred to be small or large, and as seen, the tomato is small, which is its phenotype.

19. Eubacteria - Eubacteria is a type of bacteria family that can be gram positive or negative, motile or non-motile, and have a rigid cell wall. Yogurt is a dairy product that comes from fermented milk. The milk is left to sit with bacteria that eat away some parts of the milk until a yogurt is left. One type of bacteria used in this process in Lactobacillus, which is a gram positive, anaerobic bacteria, which falls in the eubacteria family.

13. Bryophytes - Bryophytes are nonvascular plants, meaning they do not have a method of transporting fluids. This means that bryophytes must live in damp places, like where moss is found. Moss is a bryophyte through its lack of a vascular system.

15. Meiosis - Meiosis is the process by which a cell goes from 2n or diploid to n or haploid, for reproductive purposes. Seeds and nuts are methods of reproduction and so an almond is a haploid, and thus is the product of meiosis.

20. R-Strategist - An r-strategist is an organism that grows quickly, reproduces often, reproduces numerously, and depends on less parental care. Mice are a good example of this, because mice will be born with a large number of siblings, are able to reproduce younger than k-strategists, and will reproduce more often than k-strategists, which is why mice populations grow rapidly, but the individuals die younger than k-strategists.

3. Adaption of a Plant - An adaption of a plant is a trait or feature that allows them to grow and thrive in a certain area, while not in another. Such adaptions are what allow for cactuses to live in the desert or seaweed to grow in water. Seaweed is flexible to move with the water currents, and lack strong water transport systems, which they do not need being in water.

41. Vestigial Structure - A vestigial structure is a structure that over time has lost its original functionality. Like in most male mammals, nipples are present on the body. Males do not need nipples, and the nipples have no purpose, thus they are vestigial structures.
