2) A deer hears a predator approaching and begins to run for safety. The deer has primarily engaged what body systems to escape?
A nervous, respiratory, and muscular systems
B muscular, digestive, and immune systems
C respiratory, endocrine, and excretory systems
D muscular, reproductive, and circulatory system
10A (R)
3) The table below lists the types of white blood cells found in humans, indicates how abundant they are, and describes their functions.
The two most abundant types of white blood cells may both be involved in a response to which of these?
A. Injury
B. Heat
C. Allergens
D. Bacterial infection
5B (S)

2. 4) The diagram below represents an example of how the body regulates itself.
5) The statements below describe processes and
interactions in what plant function?
This diagram describes what relationship in body systems?
A. The circulatory system and nervous system interact to absorb nutrients.
B. The circulatory system and digestive system interact to defend the body from diseases.
C. The circulatory system and nervous system interact to maintain homeostasis.
D. The nervous system and immune system interact for reproduction.
A. defense against diseases
B. reproduction
C. transport of necessary materials
D. response to environmental change
10A (R)
10B (R)
6) When one side of a plant is not getting enough light, a hormone is produced in the shoot system causing growth on the darker side of the plant. This growth on the darker side causes the plant to bend. This is an example of:
A. a plant’s ability to reproduce
B. uptake of water through the plant’s root system
C. defense from possible predators
D. a plant’s ability to respond to its environmental conditions
5B (S)
7) Which scenario below best describes the interaction between the endocrine and reproductive system.
A. Hormones are produced causing ovulation in a female.
B. Muscles are contracted, pushing food from the stomach into the small intestine.
C. A male rabbit sees and chases a female rabbit.
D. A bird lays her eggs, and protects them from possible predators.
10A (R)

3. 8) What body function is identified in the process described below?
Respiratory System – mucus in the lungs traps an infectious bacteria cell
Immune System – T-cells attack the bacteria cell
Nervous System – triggers a cough to remove the mucus from the lungs along with the destroyed bacteria
A. regulation of body temperature
B. absorption of nutrients
C. defense
D. reproduction
10A (R)
9) Describe how the transport system of a plant is critical to its reproductive function.
The plant’s root system uptakes water and nutrients and delivers them to the flowering parts of the plant to support growth and development.
II. The shoot system provides structural support to the plant and upholds the flower.
III. Hormones used for seed development are transported through the root system to the shoot system.
A. I and II only
B. II and III only
C. I and III only
D. I, II, and III
10B (R)
10) Animal body systems often coordinate their actions to carry out specific functions for the whole animal. Which of these correctly describes the interaction of two biological systems for a specific purpose in the human body?
10A (R)

4. 11) As a fertilized egg divides, the cells differentiate because they-
A. Contain a lipid bilayer
B. Can clump together
C. Have specific genes activated
D. Metabolize sugars rapidly
5C (S)
12) Cytokinins are a class of plant hormones that help regulate growth by promoting cell division. Cytokinins are produced mainly in the meristematic tissue, where most plant growth occurs. Which system carries cytokinins produced in the roots to the rest of the plant?
A. Reproductive system
B. Dermal System
C. Vascular system
D. None of these.
10B (R)
13) The outermost layer of plant systems in dicotyledons consists of epidermal cells and guard cells that surround openings called stomata. The epidermal cells are usually covered with a waterproof layer that provides protection from injury and water loss. The stomata allow gas exchange. The epidermal cells and stomata have functions similar to those of which two human body systems?
A. Cardiovascular and integumentary
B. Cardiovascular and skeletal
C. Skeletal and respiratory
D. Integumentary and respiratory
10B (R)
14) Most plants have hair-like cells called trichomes that project from the surface and help the plants in many ways. In some plants trichomes secrete toxic substances that most likely perform which function?
A. Absorb carbon dioxide
B. Protect against herbivorous insects
C. Reflect light off leaves
D. Reduce water loss from evaporation
