17:You are looking at some prepared slides of different types of animal tissue. Unfortunately, the labels are so old that they have faded to the point where you can no longer read them.

A:Muscle tissue.
B:Dermal tissue.
C:Epithelial tissue.
D:Connective tissue.
18:Which of the following is the best description of the difference between physiology and anatomy?
A:Anatomy focuses on homeostasis; physiology focuses on the detailed functions required to maintain homeostasis.  
B:Anatomy focuses on the cellular and tissue levels of organization; physiology focuses on the organ, organ system, and organism levels.
C:Physiology focuses on the structure of an organism; anatomy focuses on the functions.
D:Anatomy focuses on the structures of an organism; physiology focuses on the functions.
19:Which of the following statements about plant tissue and organs is incorrect?
A:The properties of water are vital to transport through phloem.
B:Dermal tissue performs a function that is similar to breathing in animals.
C:Ground tissue in roots and leaves perform different functions.
D:the majority of photosynthesis occurs in ground tissue.

Define, describe, and explain the importance of low versus high energy charge. Why can’t a cell just make as much ATP as it wants and keep the ATP on hand until it is needed?

5:Tendons are structures that connect muscle to bone. Athletic training tends to increase the size of the tendon connecting the muscles used during training, so that the tendon operates more efficiently. Which type of tissues are involved?
A:Muscle and connective tissue.
B:Epithelial tissue only.
C:Connective tissue only.
D:Epithelial and muscle tissue.
6:Some organisms may regulate some homeostatic variables, but conform for others.
A:True
B:False

7:If you are told that an organism often uses behavior to control the value of a variable, which if the following is most likely?
A:The variable is under negative control.
B:The variable is under positive control.
C:The organism is a regulator for that variable.
D:The organism is a conformer for that variable.
8:Which of the following statements applies to xylem?
A:Some plants use specially altered xylem tissue in the roots to store sugars over the winter.  
B:Xylem is primarily responsible for moving dissolved sugars from the leaves to other areas of the plant.
C:Since it relies on the properties of water to move materials, xylem cells die at maturity to leave empty tubes that allow water molecules to stay in contact with each other though out the plant.
D:Requires the use of active transport to move material throughout the plant.

Suppose that a scientist was conducting an experiment and decided to transplant GFP-labeled cells from the dorsal region of a frog embryo at the 120-cell embryonic stage into the putative ventral side of an unlabeled zebrafish embryo of an equivalent developmental stage, state one question the scientist might have been trying to answer. Explain how this experimental design would answer the question you stated.

Transplantation could be used to build a fate map of an early embryo.

Ellie May, a mother with type B blood, has a child with type O blood. She claims that Jethro, who has type A blood, is the father. He claims that he cannot possibly be the father. Further, blood tests ordered by the judge reveal that the father is homozygous. The judge rules that:

a) Ellie May is right and Jethro must pay up.

b) Jethro is right and is a winner-winner (chicken dinner).

c) Ellie May cannot be the real mother of the child. There must have been an error made at the hospital.

d) It is impossible to reach a decision based on the limited data available.

e) none of these are correct.
