Which of the following examples demonstrates replication?
Joseph conducts his own experiment 25 times.
Sarah is following another student’s written procedures for an experiment that already performed.
Juanita conducts her experiment 1 time.
Matt writes the procedures of his experiment carefully and carries out his experiment.
Which of the following examples shows an experiment that has been designed and conducted using repeated trials and replication?
Addison is conducting an experiment using water. She has a friend look over the procedures before completing 30 trials.
Amanda is conducting an experiment using aluminum foil. She
completes her experiment 1 time and makes adjustments to her
procedures. She then completes 20 trials of her experiment.
Rashawn is conducting an experiment using tennis balls. He completes 30 trials and has 2 of his friends complete the experiment by following his procedures.
Julian is conducting an experiment using rubber bands. He completes 10 trials then begins work on a different experiment.
Which level of organization is the MOST complex, based on both size and structure?
Organism
Organs
Tissue
Cells
The heart is a structure that pumps blood throughout the human body.
Which of the following BEST represents the levels of organization that form the heart?
molecules > organ > tissues > cells > organism
organism > organ system > organ > molecules > atoms
atoms > molecules > cells > tissues > organ
tissues > cells > atoms > organ > organ system
The brain is an organ in the human body. What can you conclude about the type of structure the brain represents?
The brain is not an organ.
The brain is made up of different tissues.
The brain is not made of cells.
The brain works independently of other body systems.
Which of the following is NOT a part of homeostasis?
Having a nucleus
Extracting energy from food
Getting rid of waste
Cell reproduction
What BEST explains a way in which cells maintain homeostasis?
The cell extracts and consumes all energy from food molecules.
The cell allows molecules in to extract energy and allows molecules out to eliminate waste.
Individual cells do not maintain homeostasis for the organism.
The cell does not allow molecules in but does allow molecules out to eliminate waste.
Maintaining homeostasis requires many cell processes happening at the same time. Not all cells perform all of the same processes.
Which of the actions below is performed by all cells to maintain homeostasis?
They divide rapidly into many specialized cells.
They use light energy to produce food molecules.
They obtain energy from nutrients and remove waste products.
They combine with another cell to increase in size.
Organ systems work together to meet the needs of the human body. How is the skeletal system related to the nervous system?
The brain determines how the skeleton develops.
The brain and spinal cord hold the skeleton together.
The skeletal system controls the nervous system.
The skeleton protects the brain and spinal cord.
In order to maintain homeostasis, the systems of the human body work together to supply our cells with needed substances.
Which of the following statements describes how the human body responds to exercise?
The circulatory system delivers oxygen to the cells faster, to enable the muscles to convert energy at an increased rate.
The muscular system moves the bones to allow cellular respiration to take place.
The digestive system carries nutrients to the muscles of the muscular system to help contract and warm the muscles.
The skeletal system produces more blood cells that circulate through the blood vessels, increasing blood flow.
Sandy’s doctor said that she may have a disease known as Celiac’s disease because the nutrients from her food are not being absorb properly.
What system and organ could be causing this problem?
digestive system and large intestine
digestive system and small intestine
respiratory system and alveoli
digestive and gallbladder
Which type of infectious agent may affect humans while only being able to reproduce inside living cells?
Bacteria
Fungi
Parasite
Virus
Which of the following would be the correct label for each of the following infectious agents based on their characteristics?
Agent A: Bacteria – Agent B: Fungi – Agent C: Virus
Agent A: Bacteria – Agent B: Virus – Agent C: Fungi
Agent A: Fungi – Agent B: Virus – Agent C: Bacteria
Agent A: Virus – Agent B: Bacteria – Agent C: Fungi
A doctor is working in a lab trying to identify what type of infectious agent is causing his patient's illness. Under a microscope, he notices that the infectious agent is a small, one-celled microorganism that damages cells.
Should he prescribe the patient an antibiotic?
Yes, the infectious agent is a virus.
Yes, the infectious agent is a bacteria.
No, the infectious agent is a virus.
No, the infectious agent is a fungi.
The digestive system of an earthworm consists of specialized structures such as the crop and the intestine. What level of organization BEST describes each of these structures?
An organ
Tissue
Cell
Which series lists the hierarchy of life from largest to smallest?
Molecule, tissue, cell, organ
Organism, organ system, organ, tissue
Molecule, cell, tissue, organ system
The illustration below shows one of the human body systems.
What is the function of this system?
Provide nutrients to the body
Eliminate wastes from the body
Transport substances to all cells of the body
Body cells need oxygen to release the stored energy in food. Which system transports oxygen to cells in the body?
Digestive
Respiratory
Circulatory
The graph below shows how pulse rate changes with exercise.
Which of the following BEST explains how body systems worked together to create the results shown on the graph?
As the body is able to exercise using the musculoskeletal system, the circulatory system pumps more blood and oxygen throughout the body. The respiratory system takes in more oxygen from the environment and releases carbon dioxide.
As the body breaks down food using the digestive system, the nervous system communicates that the body needs to prevent weight gain by exercising using the musculoskeletal system.
As the body uses its excretory system to eliminate wastes, the digestive system takes in more nutrients used by the endocrine system for growth and development.
As the body’s nervous and endocrine systems are stimulated by exercise, the body’s circulatory system is less able to regulate body temperature.
Which two body systems remove waste products from the body?
Digestive and nervous
Respiratory and excretory
Circulatory and reproductive
Infectious agents that may infect the human body include viruses, bacteria, fungi, and parasites. Of these infectious agents, viruses are the only ones that are NOT a part of the Cell Theory. Why?
Viruses reproduce rapidly once inside cells.
Viruses contain hereditary information.
Viruses can infect the cells of a variety of organisms.
Viruses are not composed of cells and are not considered living.
Penicillin is one example of a type of drug known as an antibiotic. Antibiotics are a group of drugs that are used to treat diseases caused by a specific type of pathogen.
Against which type of pathogen do antibiotics work?
Fungi
Virus
Bacteria
Parasite
Many diseases are spread by contact with infectious agents. The illustration shows some ways that infectious agents are spread.
What conclusion can be made about infectious agents from this illustration?
Infectious agents are spread to humans only by direct contact with an infected person.
Infectious agents are spread to humans only by indirect contact with infected objects.
Infectious agents can spread to humans through contact with infected people or objects.
It is very difficult for infectious agents to spread from one individual to another individual.
A communicable disease is a disease that can pass from person to person. Influenza, also known as the flu, is a very serious communicable disease that is caused by a virus. Which action describes a way to avoid catching the flu?
Get a flu vaccine.
Take a flu virus antibiotic.
Get plenty of exercise with people who have the flu.
Get a blood transfusion from someone who has the flu.
