A student finds a puddle of water in a garden and takes a sample. He wants to perform an experiment to determine if there are living things in the water. How could he collect data that would provide evidence of living things?
observe the water closely to look for particles that are large enough to be seen
examine the sample under a microscope to see if cells are present
determine the amount of oxygen and carbon dioxide present in the water
measure the weight of the sample over several days to see if the weight increases
What body systems interact and work to expel wastes from the body?
digestive and circulatory
nervous and circulatory
nervous and excretory
digestive and excretory
While studying a sample of seawater, a researcher identifies a new type of bacteria and a new type of virus. The table here describes some features of each.
Which of the following statements does the information in the table support?
Viruses are living because they can reproduce in a host cell.
Viruses are nonliving because they are not made up of cells.
Bacteria are living because they can survive without food.
Bacteria are nonliving because they have to divide to reproduce.
This diagram shows levels of organization in the human body.
Which level of organization is the structure labeled with the blue X?
tissue
organism
organ
cell
Which of the following life processes requires specialized cells in multicellular organisms?
digestion
respiration
circulation
all of these
John enjoys kayaking in the river by his house. John changes the position of the oars in the water to steer the kayak and avoid rocks in his path. Which statement correctly describes how John is able to steer the kayak?
John’s eyes send a signal directly to his arms to change the position of the oars.
John’s eyes send a signal to his brain; his brain processes this information and sends a signal to his arms to change the position of the oars.
John’s arms send a signal directly to his brain to change the position of the oars.
John’s brain sends a signal to his eyes; his eyes transmit this signal to his arms to change the position of the oars.
In which list are body structures arranged from least complex to most complex?
tissue — organ — organism — cell — organ system
cell — organ — tissue — organ system — organism
tissue — cell — organism — organ — organ system
cell — tissue — organ — organ system — organism
This image shows an onion root viewed under a microscope.
What does this image best demonstrate?
Living organisms are composed of one or more cells.
New cells only arise from pre-existing cells.
Cells of different organisms have a similar composition.
Each cell can perform all functions necessary for life.
The image shows a model of a plant cell.
All cells need energy to live. How do the organelles in the plant cell above work together to get and use this energy?
Chloroplasts make food using energy from the Sun, and mitochondria break down this food to release energy for the cell.
The vacuole takes in energy from the environment, and chloroplasts change this energy into a form the cell can use.
Mitochondria take in food from the environment, and the nucleus breaks down this food to release its energy to the cell.
The nucleus makes energy from materials in the cell, and the vacuole stores this energy until the cell needs to use it.
Cells routinely release wastes as they perform their functions. In the human body, this waste is often released into the bloodstream. Which organ removes much of this waste from the bloodstream so that it can then also be removed from the body?
the lungs
the stomach
the heart
the kidneys
A _______ is a rigid layer that surrounds a plant cell, providing structural support.
cell wall
cell membrane
cytoplasm
nucleus
What important life function takes place in the mitochondrion?
Proteins are created and packaged for transport.
Sunlight is collected and converted to chemical energy.
Important parts of the cell membrane are manufactured.
Food molecules are broken down to release energy.
Sofia used a microscope to get a closer look at some cells. She drew an image similar to the one here based on what she saw.
Sofia concluded that these cells were from a plant instead of an animal. What did she see that led her to this conclusion?
cell walls
nuclei
cytoplasm
cell membranes
Which of the following organelles is found in most plant cells, but is never found in animal cells?
chloroplasts
cell membrane
mitochondria
nuclei
Directions: Select the correct answer. Which system breaks down food, and which system transports nutrients to the cells of the body?
Digestive system; Circulatory system
Respiratory system; Nervous system
Skeletal system; Muscular system
Integumentary system; Endocrine system
Which organelle is the control center of the cell?
nucleus
chloroplasts
cell membrane
mitochondria
Systems in the body interact to carry out life functions. The muscles of the body are part of the muscular system. Which system provides the impulses that cause the muscles to contract?
nervous
circulatory
respiratory
digestive
Cells produce waste as part of their normal activities. Cellular waste is collected by blood in the
circulatory system. The kidneys are organs that filter cellular waste from the blood. This waste
is stored in the bladder until it can be excreted from the body.
* (Look at this picture.) In this example, which system is the circulatory system interacting with?
nervous
respiratory
digestive
excretory
In an organism, how are cells related to tissues?
Tissues make up organs, which make up cells.
Cells make up organs, which make up tissues.
Groups of cells cooperate to form tissues.
Groups of tissues cooperate to form cells.
Which type of cells are most responsible for relaying information to the brain about external stimuli such as heat?
nerve cells
muscle cells
white blood cells
red blood cells
What kind of cells send and receive messages?
nerve cells
muscle cells
bone cells
skin cells
In order for the body to respond to external stimuli, it must first receive the stimuli through the __.
senses
muscles
bones
organs
What is the function of organelle 2?
to break down the cell's wastes
to supply the cell with energy
to control the cell's activities
to make proteins for the cell
Which two body systems pictured above interact with each other to break down and transport the nutrients found in food?
the circulatory system and the digestive system
the digestive system and the nervous system
the nervous system and the respiratory system
the respiratory system and the circulatory system
