1. True or False? Simple, non-photosynthesizing prokaryotes are hypothesized to
be the first living life-forms on Earth.: True
2. True or False? Acclimations are short-term, genotypic characteristics of an
organism.: False
3. True or False? The size of a cell is limited based on the need of adequate surface
area for the cell's volume.: True
4. True or False? All members of kingdom fungi form a large monophyletic
group.: True
5. True or False? Cells become specialized/differentiated because they contain
different genes in their genome during development.: False
6. True or False? The function of loose connective tissue is to provide padding
under skin and between organs.: True
7. True or False? Collagen is a main protein component of the extracellular matrix
of loose connective tissue.: True
8. True or False? The renal cortex of a human kidney has higher salt content than
the renal medulla.: False
9. True or False? The least probable result of a mutation to DNA is a new trait
that is deleterious or harmful to the organism.: False
10. True or False? Cells located within different regions of a somite will encounter
varied chemical signals surrounding tissues and differentiate into structure
accordingly.: True
11. Diffusion of gases occurs from an area of HIGH partial pressure to and area of
LOW partial pressure.: true
12. True or False? During development, primary germs layers first form during
organogenesis.: False
13. Which is not a characteristic of osmoregulation in marine (salt-water) fish?:
Lose bodily electrolytes (salt) through diffusion.
14. Skeletal muscle is considered to be:: Striated & Voluntary
15. A population of frogs resides in cheat lake. The majority of this population has
an average leg length opt 2-6 inches are found in the population in low
numbers. A new species of flying insect appears in the area. These insects are
fast flyers and the frogs that are able to catch these insects need greater leg
power to jump higher and faster than previous generations. Overtime, the
average leg length of the majority of frogs in Cheat Lake becomes 6 inches. This
is an example of what type of selection?: Directional selection
, .
16. Which of the following lists contains the steps of development in the correct
order?: Fertilization, cell cleavage, gastrulation, organogenesis
17. Endotherm: Produces their own heat
18. Ectotherm: Rely on heat from the environment
19 Homeotherm: Keeps body temperature constant
20. Heterotherm: Allows body heat fluctuations
21. Master regulator genes: Establishes anterior and posterior ends of a developing
organism
22. Pair-rule genes: Cells organized into individual segments
23. Effector genes: Triggers apoptosis
24. Homeotic genes: Responsible for the correct placement of appendages/structures
25. A mutation within a gene of the developmental regulatory cascade is responsible
for legs growing where they do not belong. A mutation in which type of gene is
most likely responsible for the phenotype in this image?: Homeotic gene
26. Cortical reaction of fertilization: -Begins upon the entrance of a single sperm cell
into an egg cell.
-Prevents polyspermy from occurring.
-Cortical granules are activated by the release of Ca²z at the site of sperm entry.
-The content of cortical granules act to help lift away the jelly layer of the egg.
27. Which type of connective tissue excretes a liquid extracellular matrix?: Blood
28. Habitat Isolation: Populations live in different habitats and do not meet
29. Temporal Isolation: Matting or flowering occurs at different seasons or times of
day
30. Behavioral Isolation: Little or no sexual attraction between males and females
31. Gametes Incapable of Fusion: Sperm cannot penetrate the eggs outer covering or
that sperm cannot swim well in the reproductive tract.
32. Hybrid Inviability: Hybrid embryos die early or new individuals die before they
can reproduce
33. Considering the three types of nitrogenous wastes produced in animals, which
of the following statements is true?: Uric acid is not soluble in water
34. Characteristics of cross current exchange: -Oxygenated water and non-
oxygenated blood flow in opposite directions across gill tissue.
-Maximizes diffusion.
-Is utilized by aquatic organisms.
-Keeps diffusion of oxygen between water and blood moving across the entire surface of
the gill tissue.
