Part 2 – How do the systems work together to help Tom to lift the book?

he nervous system sends signals from Tom's brain to his muscles, telling them to contract and lift the book. The muscular system provides the strength and force needed to lift the book, while the skeletal system provides a framework for the muscles to attach to, allowing movement.

200

A biologist is looking at an animal cell under a microscope, and noticed there is something wrong

with the way it is functioning. It is not allowing water into the cell. Look at the diagram below and

identify the location in the cell where this problem is most likely occurring.

Location A

200

Plants rely on the process of photosynthesis to grow and reproduce. What resources do they

need for this process?

d. energy from the sun; matter from water and carbon dioxide in the Air

200

Many systems of the body are interconnected. Why might a disorder that affects the nervous

system cause a person to have difficulty walking?


d. The nervous system disorder may disrupt the ability of the brain to send impulses to the

muscles, telling them to move.

200

Frankie makes the claim that all three seeds from the data table show evidence of gravitropism.

Is he correct? Explain your reasoning.

a. Yes, because the stems and roots are all growing downward.

b. No, because the seeds are all in different positions relative to the stems and roots.

c. Yes, because the roots are growing downward while the stems are growing upward.

d. No, because both stems and roots are growing upward.

c. Yes, because the roots are growing downward while the stems are growing upward.

Harry examines a drop of pond water under a microscope. He draws pictures of structures

that he observes, counts them, and measures their sizes. Eight hours later, he comes back

and observes the same drop again. He counts the structures and measures their sizes.

Alonzo went hiking up a local mountain. The lack of oxygen at such a high altitude on the

the mountain caused his body to respond. Which of the following accurately describes how Alonzo’s

systems worked to maintain homeostasis at such a high altitude?

a. He breathed faster, which allowed more oxygen into the lungs, and through the bloodstream, where it is delivered to the cells.

300

This energy pyramid shows the flow of energy in an aquatic food chain. Choose the statement

that correctly describes the flow of energy in this diagram.

c. As you move up the pyramid, there is less energy at each level.

300

Plants use the energy they obtain from the sun to make sugar molecules, which help the plants

grow. How could a student add to this model to show where the sugar molecules fit in?

c. by drawing the sugar molecules as an output of energy from within the chloroplasts

Part B – What is the evidence for your answer(s)? Select all that apply.

a. The number of the structure increases.

b. The average size of the structure increases.

c. The number of the structure stays the same.

d. The average size of the structure stays the same.

a. The number of the structure increases.

A biologist is observing an organism under a microscope and concludes that it is a unicellular

organism.

Which of the following observations provides evidence that this organism must be unicellular, not

multicellular?

d. It performs all functions to maintain life.

400

Plants and animals get the energy for life-supporting functions from a process called cellular

respiration. When combined with photosynthesis, it represents a cycle of matter and flow of

energy between animals and plants.

d. Part D

e. Part E

Below are four examples of animal behavior. Read each description and decide If it is an example

of homeostasis. If it is an example of homeostasis, label it with a ‘Y.’ If it is not an example of

homeostasis, label it with an ‘N.’

Dog panting to bring down

body temperature after

a run. Y


Penguins huddling together

to conserve heat in

cold environments. Y


Salmon living in salt water

drink several liters of water in

response to dehydration/having

too much salt in the body. Y


 Kittens crying after their

mother leaves the room. N

Priya needs help writing a passage about the structures in different living things. There are three

areas in this passage that need your help. Circle the correct option to complete the passage.

Before the invention of the microscope, scientists did not know about cells. By observing

samples of many different animal and plant tissues under microscopes, scientists

discovered that all living things are made of [cells / organelles / DNA / a nucleus].

Because a single cell grows, develops, reproduces, responds to its environment, and uses

energy, scientists also know that [all living things are made of one type of cell / living

things are made of many cells / all living things have organs / living things may be made

of one cell].

The human body consists of different structures at different scales. There are about 5

liters of blood in the body. A drop of blood is visible to the unaided eye, but it is necessary

to use a microscope to see the [hundreds / thousands / millions / billions] of cells that

make up the drop of blood.

  1. Before the invention of the microscope, scientists did not know about cells. By observing samples of many different animal and plant tissues under microscopes, scientists discovered that all living things are made of cells.

Animal cells have structures that perform specific functions in the cell. Mitochondria

are organelles that float within the cell. Because they produce most of the cell’s energy,

mitochondria are nicknamed the “powerhouse of the cell.”

Which of the following types of cells would have the greatest number of mitochondria?

c. muscle cell

500

Humans rely on sensory receptors to interpret messages about their surroundings. Sensory

receptors respond to mechanical, physical, or chemical stimuli. There are different kinds of

sensory receptors for detecting different kinds of stimuli. Chemoreceptors are specialized nerve

cells that pick up chemical stimuli, such as smells or the pH level of foods. Such stimuli tell the

brain and body to react a certain way to protect the body.

If a person in a controlled test is introduced to a safe chemical stimulus, what is the most logical

prediction you could make?

b. The person will plug the nose to shield the body from offensive chemical smells.
