When the skin comes in contact with an irritant, receptors in the skin send signals to the spinal cord. The signal is then sent to the brain for processing, and the individual begins to scratch the affected area.
Which systems are most likely interacting when a person experiences itching caused by a skin irritant?
How do other body systems interact with the digestive system to regulate body processes?
Select TWO correct answers.
When an athlete starts a race, the body responds to maintain homeostasis. A table describing the body's response is shown.
Which set of statements describes how body systems interact in response to an increase in body temperature?
Which sequence best describes an interaction between the digestive and endocrine systems that helps maintain homeostasis?
The diagram below represents how body temperature changes over time.
Sweating and shivering occur at different times and are regulated because...
This question has two parts. Use the information below to answer the following questions.
When exposed to cold temperatures, the human body works to maintain a stable internal temperature. Blood vessels near the skin constrict to reduce heat loss, and muscles begin to shiver to generate warmth. The brain also signals the release of hormones that increase metabolism to produce more body heat.
Part A
Which two body systems are MOST DIRECTLY involved in helping the body maintain homeostasis in response to cold temperatures?
Match the description to the type of tropism below.
| Draggable item | arrow_right_alt | Corresponding Item |
|---|---|---|
Response to light | arrow_right_alt | Thigmotropism |
Response to touch | arrow_right_alt | Geotropism |
Response to Earth's gravity | arrow_right_alt | Hydrotropism |
Response to H2O | arrow_right_alt | Phototropism |
Select which phrases complete the diagram describing how plants respond to their environments.
Which tropism is this an example of?
Orchids grow on the branches of mango trees in order to reach sunlight. The orchid does not get nutrition from the mango tree and the tree is neither harmed nor helped in this interaction.
In this example of commensalism, how does the orchid benefit?
The mimosa plant displays thigmotropism by collapsing its leaves in response to touch, as shown in the pictures below. The plant on the left is undisturbed. The upper stem of the plant on the right has been touched.
Which of the following best describes how mimosa plants respond to stress from their environment?
A student sets up a controlled experiment by growing lima beans in two different conditions. After one week, the students recorded their observations in their notebook as shown below.
Which of the following describes what caused the roots of the plant to grow as shown in the observation recordings?
Observe the diagrams below of plant watering methods. The ceramic pots are opaque (cannot see through them), however predictions can be made as to how the roots of the plant will grow.
Which of the following conclusions can be made considering hydrotropism and the watering methods shown?
Select TWO correct answer choices.
Which systems are interacting to maintain homeostasis based on the diagram?
Select THREE correct answers.
Part B
Which statement BEST supports the answer to Part A?
