3. Name the division of the peripheral nervous system that is activated in each of these
examples:
a. You are startled when a friend pulls a practical joke and spooks you with a loud sound.
b. You move your arms and legs to take an evening walk.
c. Your stomach makes a gurgling sound as it digests your lunch.
d. Feeling a little stressed? You take a few breaths to calm down.
e. You are at the line, waiting for you race to start, and your heart begins to pound.
A startle reflex (a), digestion (c), breathing (d) and heart pumping (e) are responses of the ANS, while arm/leg movement (b) is a response of the SNS. They are major divisions of the PNS.
The peripheral nervous system (PNS) serves to connect the central nervous system to different organs, limbs, and skin.
The PNS can be divided into Somatic Nervous System (SNS) and Autonomic Nervous System (ANS).
The Somatic Nervous System is responsible for controlling the voluntary movements of the body.
The Somatic Nervous System is responsible for regulating the involuntary movements (reflexes) of the body.

At the end of binary fission, the two daughter cells that result are genetically _________ to each other and to the parent cell.
A. different
В. identical

How has vehicle fuel consumption in comparison to miles traveled changed since 1960? What is the likely cause for this change?
Answer:
After World War II, economic growth, population growth, rapid suburbanization, and the closing of some public transit systems led to more reliance on personal vehicles for transportation. The number of cars and trucks in the United States increased dramatically, as did the number of highways. One result of the rapid increase of motor vehicles was air pollution, especially in cities, that had serious impacts on public health and the environment.

Use examples to explain how the biosphere interacts with two other of Earth's spheres. Explain the interaction for each using complete sentences.
Answer:
The biosphere is influenced by other spheres and also influences other spheres.
The biosphere comes into contact with several other spheres such as the hydrosphere, the lithosphere, and the atmosphere.
Contact with the atmosphere is a two way street since the biosphere can alter the composition of the atmosphere. However, many members of the biosphere like mammals and birds depend on the mix of gases in the atmosphere to survive, and weather is an important agent of change.
The lithosphere is another sphere that can impact the biosphere through geologic activity both underground and on the surface. The impact of the biosphere on the lithosphere can be observed through the altering and transformation of terrains and through biochemical weathering of rocks.

Explanation:
Read this paragraph from "How Water Loss Affects Biodiversity."
“When a region experiences a significant drought, many animals may die from lack of water and food. […] If tourism declines due to high wildlife casualties, then the locals who depend on income from tourism will lose their livelihood. People may then turn to farming to earn money, but crops require water to grow. This can place further strain on the water supply and worsen the original problem of the drought.”
What event can cause many animals to die from lack of water and food?
Answer:
Eggs and fried chicken with mentally stabled fries
