Animal and plant systems

What two human systems work together to provide body cells with a constant supply of oxygen while removing carbon dioxide waste products?

• Nervous and endocrine
• Muscular and skeletal
• Respiratory and circulatory
• Excretory and integumentary

When a person is suddenly cut by a sharp object, a nervous impulse is sent along a sensory neuron to the spinal cord. The impulse is immediately transmitted through motor neurons to produce a response. Which of the following correctly identifies and describes this response?

• It is a conditioned response that occurs only to prevent injury.
• It is a learned response that does not occur in infants or small children.
• It is a reflex response that causes various muscles to contract in order to move away from the object.
• It is a voluntary response that is initiated only after the impulse has been carried to the relevant area in the brain.

The human digestive system is approximately 900 cm. long. Food is moved through the digestive tract primarily by - 

• bile produced by the pancreas
• the enzymes amylase and pepsin
• muscular contractions
• hydrochloric acid in the stomach

The scenario above is best described by the interaction of what three body systems?

• X=respiratory system, Y=circulatory system, Z=reproductive system

• X=muscular system, Y=nervous system, Z=immune system

• X=circulatory system, Y=immune system, Z=muscular system

• X=muscular system, Y=digestive system, Z=circulatory system

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?

• Absorb carbon dioxide

• Protect against herbivorous insects

• Reflect light off leaves

• Reduce water loss from evaporation

A deer hears a predator approaching and begins to run for safety. The deer has primarily engaged what body systems to escape?

• nervous, respiratory, and muscular systems

• muscular, digestive, and immune systems

• respiratory, endocrine, and excretory systems

• muscular, reproductive, and circulatory system

The table above 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?

• Injury

• Heat

• Allergens

• Bacterial Infection

The diagram above represents an example of how the body regulates itself. This diagram describes what relationship in body systems?

• The circulatory system and nervous system interact to absorb nutrients.

• The circulatory system and digestive system interact to defend the body from diseases.

• The circulatory system and nervous system interact to maintain homeostasis.

• The nervous system and immune system interact for reproduction.

• reproduction

• transport of necessary materials

• response to environmental change

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 plant’s ability to reproduce

• uptake of water through the plant’s root system

• defense from possible predators

• a plant’s ability to respond to its environmental conditions
