Skeletal
What is the function of the digestive system?
Transport and exchange of gasses between the body and the environment.
Transporting and breaking down large food molecules into smaller molecules so it can be used by the body.
Transport of nutrients, gasses, wastes, and other substances through the body.
Transport and defense to remove excess fluid from around organs, producing white blood cells, and absorbing and transporting fats.
Which of the following correctly describes the physical and chemical changes that occur during digestion?
Physical-when the food is broken down by enzymes and chemical when the food mixes with stomach acids.
Physical-when food is cut and grinded by teeth and chemical when food is mixed with enzymes in saliva.
Physical-when food is cut and grinded by teeth and chemical when food is moved from your mouth into your stomach.
Physical-when food is mixed with saliva and chemical when food is moved from the mouth into the stomach.
In humans, chemical energy in food is transformed into –
electrical energy during exercise.
electrical energy during digestion.
thermal energy during digestion.
radiant energy during exercise.
What is the name and function of the body system pictured above?
Excretory system: Transport and removal of solid, liquid, and gas waste from the body.
Circulatory System: Defense and protecting the body from harmful substances in the external environment.
Excretory System: Transport and breaking down of food into smaller parts so it can be used by the body.
Respiratory System: Transport and exchange of gasses between the body and the environment.
Which of the following does NOT aid in reproduction?
Penis
Vagina
Bladder
Ovaries
The body system that produces hormones and regulates body functions is the
Skeletal system
Nervous system
Integumentary system
Endocrine system
A student touches a hot stove and immediately withdraws her hand from it. Signals from her hand to her brain instruct her body to quickly remove her hand from the hot stove. Which body system initiated this response?
Endocrine system
Integumentary system
Nervous system
Skeletal system
What is the function of the integumentary system?
Blocks germs
Protects the body from the external environment
Both A & B
None of the above
What cellular organelle is indicated by the arrow and what function carried out by an organism is most similar to the function of the organelle?
Mitochondrion; digestion, because food is broken down into a usable form
Cytoplasm; circulation, because fluid and molecules are moved around
Cell wall; skeletal, because structure is provided for an organism
Cell membrane; integumentary, because it is protected from the external environment
Maria went for a bike ride one spring afternoon. After a while, she was sweating, breathing hard, and could feel her heart pounding. Time for a break! She saw that many different flowers were blooming in an open field and stopped to smell some of them. After a few minutes, her eyes and throat started to itch, and she began sneezing. Uh oh! She was allergic to the flowers! She got back on the bike and headed home. Which body system was responsible for her to make all of these movements?
Integumentary
Respiratory
Muscular
Endocrine
Which statement best describes Sexual Reproduction?
Any organism that produces offspring that contains exactly the same genetic information as itself.
Genetic information is passed on from each parent to form diverse offspring.
Any organism with only one parent but can produce many variations of offspring.
Two parent cells that combine to form offspring that is identical to that of one of the parent cells.
Which statement best describes Asexual Reproduction?
Any organism that produces offspring that contain exactly the same genetic information as itself.
Genetic information is passed on from each parent to form diverse offspring.
Any organism with only one parent but can produce many variations of offspring.
Two parent cells that combine to form offspring that is identical to that of one of the parent cells.
Which of the following statements best describes the offspring of organisms that reproduce sexually?
It produces offspring that inherit traits from both parents, and will result in offspring that are diverse.
It produces offspring that will not look like either parent.
It produces offspring that inherit traits from both parents, although
the offspring will end up being identical to one of the parents.
It produces offspring where the girls will be exactly like the female parent or boys that will exactly like the male parent.
What does B stand for in the acronym B.A.P stand for ?
(a)
Which of the following statements is the correct explanation of natural selection?
Natural selection is the process that passes learned skills from parent to offspring
Natural selection is the passing of genetics traits from parents to offspring by human influence.
Natural selection is the environmental influence on the traits that can lead to genetic changes from generation to generation
Natural selection is the passing of traits from offspring to parent by nature's influence.
Which of the following statements is the correct explanation of selective breeding?
Selective breeding is the passing of genetics traits from parents to offspring by human influence.
Selective breeding is the process that passes learned skills from parent to offspring.
Which definition of adaptation correctly matches an example of adaptation?
an inherited trait that increases an organism’s chance of surviving and reproducing in a particular environment - animal migration
an inherited trait that increases an organism’s chance of surviving and reproducing in a particular environment - ability to roll tongue
How does variation enhance survival?
It allows the species to adapt to the environment so that the population can survive.
It allows species to look differently so that animals can be identified.
It allows populations to evolve so that all of the animals can be healthy and strong.
It allows the population to pass on identical genes from parents to offspring.
Peppered moths often hide on white-colored birch trees because they are similarly colored. Which of the following environmental changes lead to the enhanced survival of darker moths?
Warm weather caused the birch trees to grow their leaves back early.
Birch trees became covered in black ash from nearby factories.
Heavy rainfall caused birch trees to grow taller than normal.
Disease killed off more than half of the birch tree population.
Which of the following is an example of variation in a species?
Finches have different beak shapes due to different food sources.
All birds fly because they have feathers.
Birds have feathers that cover their body to help them fly or swim
Variety of food sources available for the species.
A species of rats live in a certain type of tree with the branches evenly spaced. Smaller rats could not reach from branch to branch and larger rats would break the branches and fall. Over a period of time, all rats were just the right size for the tree branches.
From the passage which type of rats would survive living on the tree?
Large rats because they would eat all the small rats.
Small rats because they can hide in the tree better.
Medium rats because they would not fall through the branches nor break the branches.
Rats would not survive in the tree.
