Flag question: Question 2
Question 20 pts
Some organisms, such as mammals, have closed blood circulation systems. In mammals, blood is moved throughout the body inside blood vessels. Other organisms, such as insects, have open blood circulation systems. In insects, blood is moved to large spaces inside the body, where it comes into contact with tissue. Despite working in different ways, these blood circulation systems have similar purposes. Which statement correctly describes one of the purposes they share?
Group of answer choices
Both systems move materials throughout the organism's body.
Both systems remove harmful waste products from the organism's body.
Both systems transmit signals from the organism's muscles to its nervous system.
Both systems change food into useful nutrients and energy for the organism's cells.

Question 30 pts
Fires during dry seasons in the savanna (grassland) biome maintain community health. Some consumer organisms, like insects and mice, are killed by these fires, while other consumers, like birds, eat organisms affected by the fires. How does this pattern best illustrate the effect of diversity?
Group of answer choices
It reduces the frequency of negative environmental events.
It allows organisms to adapt more rapidly to changing local conditions.
It helps maintain the overall ecosystem health and efficiency of resource use.
It prevents selection pressure from affecting organisms with the environment.

Question 40 pts
Which internal structures in humans have the most similar functions to that of xylem in maple trees?
Group of answer choices
lungs and skin, since they are involved in gas exchange
nerves and brain, since they respond to environmental stimuli
bones and muscles, since they are responsible for movement
veins and arteries, since they transport blood throughout the body

Robotic Roaches
Scientists and engineers regularly study nature to develop new technology. The development of robotic insects has involved the use of high-speed videography to study the motion of insect wings during flight. This same technology is also being used in other laboratories to study the movement of cockroaches.

Scientists have observed cockroaches flattening their bodies to move through cracks no thicker than two stacked pennies. Studying the video images, scientists observed cockroaches using sensory spines on their legs to push against the floor instead of using their feet. Even more amazing, the cockroaches' speed remained nearly the same as when they were on their feet. Scientists also studied the cockroaches' jointed exoskeleton. It is made up of both hard plates and flexible membranes, which allow changes to the cockroaches' body shape. Their smooth wings also reduce resistance in tight spaces. All of these observations led to the development of a cockroach bot that can compress and squeeze through extremely small places.
How do the sensory spines most likely help the cockroach survive in its environment?
Group of answer choices
They improve the cockroach's vision so it can see predators sooner.
They allow the cockroach to change its body shape to confuse predators.
They reduce the friction along the top of the cockroach so it can move faster than predators.
They allow the cockroach to move through small spaces where it is unable to use its feet to escape predators
