Answers

Animal Movement

1) If you were a fish (and if all these activities were possible), how would you try to disguise yourself from a fisherman using a sonar fish finder?

(D) Remove the air from your swim bladder

The air within the swim bladder is the part of the fish that is detected by sonar signals sent out from fish finders.

2) The       of water is       than the density of air.

(C) density, higher

Density is a comparison of mass to volume (density = mass/volume). For a given volume (perhaps a 2 liter bottle) that is filled with either water or air, the bottle filled with water will have a much greater mass. Therefore, it has a higher density.

3) Which of the following is NOT a modification that aids in flight?

(A) Blubber

Birds have feathers that make up the airfoil (which is absolutely required for all flight). Birds also have other adaptations that make them lighter including: laying eggs outside their body (oviparity), bones that are hollow, and a fast digestive system that moves food through their bodies as fast as possible. Blubber is a type of fat commonly found in marine mammals.

4) Which of following is NOT a quadruped gait pattern?


(E) Hop

Quadruped, or four-legged organisms, can walk, trot, pronk, or even rotary gallop. However, hopping, the most efficient way for kangaroos to travel, can only be accomplished on one or two limbs.

5) Male birds perform some of the most intricate forms of animal movement for what purpose?

(B) Attracting a mate

During mating season, male birds will perform elaborate dances to attract a female. All the hard work pays off if the female chooses the male.

Animal Circulation

1) What order does the blood travel after it leaves the heart for systemic circulation? 

(B) artery → capillary → vein

Like a mailman delivering packages and picking up new parcels, during systemic circulation the blood needs to deliver oxygen to tissues throughout the body and pick up CO 2. When it leaves the heart it carries oxygenated blood through the thick arteries, exchanges oxygen for carbon dioxide in the tiny capillaries, and carries the CO 2 laden blood back to the heart.

2)       and       are the primary oxygen transporters in blood and hemolymph, respectively?

(D) hemoglobin, hemocyanin

Hemoglobin on red blood cells can carry up to 4 oxygen molecules in blood. Hemocyanin, which roams free in hemolymph, carries one oxygen molecule.

3) How many chambers are in a fish heart?

(B) 2

Fish hearts are part of a single circulatory pathway and have one atrium and one ventricle (2 chambers). Other animals have a 3- or 4-chambered heart that sends blood through a second pathway to the lungs (a process that is unnecessary in fish thanks to their gills)

4) What are the blood vessels that bring blood to supply oxygen to heart cells called?

(A) Coronary arteries

Arteries carry away from the chambers of the heart. Coronary arteries carry this blood right back to the heart tissue to keep heart cells full of energy. Pulmonary arteries carry blood to the lungs to pick up oxygen.

5) What is the function of white blood cells?

(A) Patrolling the body looking for pathogens

Red blood cells carry oxygen and carbon dioxide. Platelets aid in clotting. White blood cells are like your body's army, moving around the body and attacking invaders.

Animal Respiration

1) Buccal Pumping is      .

(B) A type of lung ventilation used in amphibians

Since amphibians tend to lack diaphragms they need to use a process called buccal pumping where they pull in air by expanding a buccal cavity and then force the air into their lungs with throat muscles.

2) As water flows past the gills, the blood is arranged to flow in the opposite direction to the water, this helps the blood to      ?

(A) Gather the maximum amount of oxygen as it passes by

Because the water is flowing opposite the direction of blood flow the blood is water is constantly coming into contact with water that is fully oxygenated.

3) What type of an animal has tracheae?

(B) Beetle

Beetles, the only insects listed above, have a system of tubes, called tracheae, that supply oxygen directly to the tissues.

4) Carbon dioxide and water are the waste products of      .


(B) Cellular respiration

Cellular respiration is the process cells use that requires oxygen to make energy and gives off carbon dioxide and water. Photosynthesis uses carbon dioxide. The other choices are not chemical reactions.

5) Which of these is between the trachea and the bronchioles on the pathway of air into the lungs in mammals?


(C) Bronchus

The trachea splits into the two bronchi before reaching the smaller bronchioles. Remember the correct order of respiration is the nose and mouth, epiglottis, trachea, broncus, bronchioles, and alveolus.

Homeostasis

1) Osmoregulation is important in homeostasis because it keeps       and      in balance.

(D) Water and solutes

The process by which water moves is called osmosis, and osmoregulation keeps water ant the solutes dissolved in water in balance. Plants and animals, efferent and afferent pathways, circulation and respiration, as well as endotherms and ectotherms rely on osmoregulation to function properly.

2) Fresh water fish osmoregulate by      .


(B) Expelling dilute urine

Freshwater fish live in an environment that has little salt within the water. This means that the inside of the fish is saltier than the water. Freshwater (NOT saltwater) from outside moves into the fish to dilute the salt. To remove the excess water, the fish has to expel a lot of water in its urine, which means it expels dilute urine, NOT concentrated urine. Eating fish does not have a direct affect on osmoregulation.

3) Which of the following is NOT directly controlled by homeostasis?

(C) Mating Ritual

pH, temperature, oxygen level, and blood sugar are all controlled by homeostatic mechanisms. Homeostasis affects the internal environment of an organism so outward expressions, like a mating ritual, are not directly under control of homeostasis.

4) After osmosis, which of the following will theoretically NOT be true?

(B) The solute concentrations in both locations will be unchanged.

Osmosis occurs when water moves from areas of lower solute concentration (hypotonic) to areas of higher solute concentration (hypertonic). This causes the concentration of solutes to CHANGE in both areas until the concentrations are equal (also called isotonic).

5) Water usually moves      a hypertonic fish (or cell).

(A) Into

A hypertonic fish has a higher internal solute concentration than the water outside it. Water moves towards the hypertonic direction (high concentration) so it would move into the fish (or cell).

Temperature Regulation

1) Which of the following is NOT something that an ectotherm would do to regulate its temperature?

(C) Shiver

Ectotherm temperature is highly dependent on their external environment. If an ectotherm was becoming too hot, it might sit on a cold rock or move underground. It it was too cool it may move to a hot rock or constrict its outer blood vessels to keep the blood in the core. Shivering is a form of generating heat and ectotherms cannot generate heat, but instead need to receive heat from their environment.

2) Which type of heat transfer occurs from a lizard lying on a warm rock?

(C) Conduction

The rock is warmed by radiation from the sun, but because the lizard is in direct contact with the rock (not a liquid or gas), the heat is transferred by conduction. If the sun is still shining on the rock with the lizard on it, the lizard is also warmed by radiation but we don't know this from the question.

3) Enzymes usually work      .


(D) At a specific temperature

Enzymes usually have a very specific temperature that they work at in order to be active. This temperature is not dependent upon the season.

4) Many DEEP ocean fish are ectotherms and      .

(A) Homeotherms

Ectotherms get their temperature from their environment and the deep ocean temperature changes very little. Thus, deep ocean fish have a constant body, making them a homeotherm.

5) Ectothermic animals are usually active      .

(A) During the day

Ectotherms are often inactive at night and in the winter due to the cooler temperatures. Since ectotherms rely on external production of heat, they often have periods of inactivity that correlate with cooler temperatures. When their internal temperature drops, their enzymes become less effective and their metabolism decreases. Lower metabolism means less energy, and less energy means less movement.
