Biting flies can transmit diseases and cause loss of blood for animals in nature. Horses have developed behaviors to repel biting flies such as ear twitching, head tossing, leg stomping and tail swishing.
Which statement best describes the interaction between body systems that allows horses to repel biting flies?
The nervous system senses the biting flies and sends a signal to the muscular system to move.
The circulatory system senses the biting flies and sends a signal to the nervous system to move.
The muscular system senses the biting flies and sends a signal to the integumentary system to move.
The integumentary system senses the biting flies and sends a signal to the circulatory system to move.
Positive thigmotropism is a response in plants in which they move and grow toward an object the plant comes into physical contact with, usually curling around the object.
This response of the shoot system benefits the plant by allowing the plant to —
produce more pollen for pollinators
take in more carbon dioxide to convert into glucose
absorb more water to transport to the leaves
reach more sunlight for photosynthesis

Which sequence best describes an interaction between the integumentary and excretory systems that helps maintain homeostasis?
Heart rate increases -> Blood vessels constrict -> Blood pressure increases
Blood vessel is damaged -> Platelets begin to clump -> Blood vessel ruptures
Blood sugar levels rise -> Pancreas secretes insulin -> Blood sugar continues to rise
Body temperature increases -> Glands release sweat -> Body temperature decreases
A model of an enzyme and its corresponding substrate is shown.
Which model best represents the molecule at the end of the reaction?
Which statements best compare a function of proteins and lipids in a human cell?
Proteins provide energy for cellular processes. Lipids catalyze chemical reactions inside the cell.
Proteins catalyze chemical reactions inside the cell. Lipids allow for the transport of certain molecules into and out of the cell.
Proteins allow for the transport of certain molecules into and out of the cell.
Lipids store genetic information for cells.
Proteins store genetic information for cells. Lipids provide energy for cellular processes.
Both the respiratory system and the digestive system involve the uptake of necessary molecules from an animal’s surroundings. Alveoli are tiny sacs that aid in the exchange of carbon dioxide and oxygen in the lungs. Intestinal villi are tiny projections along the lining of the intestines used to take in nutrients from food passing through.
Which system must interact with the respiratory and digestive systems to transport gases and nutrients throughout the body?
Endocrine
Integumentary
Immune
Circulatory
A model of two structures that perform cellular processes is shown.
What are the products of the cellular process in these organelles?
I: glucose and carbon dioxide II: oxygen and water
I: carbon dioxide and oxygen II: glucose and water
I: oxygen and glucose II: water and carbon dioxide
I: carbon dioxide and water II: glucose and oxygen
Water, sugar, and other important nutrients need to be transported from one part of a plant to another. Which statement correctly describes the interaction of the root and shoot systems during nutrient transport?
The leaves take in water and sugar, which are then transported to the rest of the plant through vascular tissues.
The roots take in water and sugar, which are then transported to the rest of the plant through vascular tissues.
The leaves take in water and the roots produce sugar that are transported to the rest of the plant through vascular tissues.
The roots take in water and the leaves produce sugar that are transported to the rest of the plant through vascular tissues.
