This is the type of muscle tissue attached to bones that allows voluntary movement.
What is skeletal muscle?
This is the largest organ of the human body.
What is the skin?
This is the number of bones in a typical adult human skeleton.
What is 206?
This organelle contains DNA and acts as the cell’s control center.
What is the nucleus?
This is the broadest category in the modern classification system.
What is a domain?
This type of muscle is found in the walls of hollow organs, such as the stomach, intestines, and blood vessels.
What is smooth muscle?
This outermost layer of the skin contains no blood vessels.
What is the epidermis?
This is the longest and strongest bone in the human body.
What is the femur?
These organelles build proteins by linking amino acids together.
What are ribosomes?
Three domains include Bacteria, Archaea...but which one contains plants, animals, fungi, and protists?
What is Eukarya?
This involuntary muscle tissue is found only in the heart.
What is cardiac muscle?
This skin pigment helps protect cells from ultraviolet radiation and contributes to skin color.
What is melanin?
This type of connective tissue connects bone to bone at a joint.
What is a ligament?
This organelle modifies, sorts, packages, and ships proteins.
What is the Golgi apparatus, or Golgi body?
Organisms in this domain are prokaryotic and are commonly found in ordinary environments such as soil, water, and the human body.
What is Bacteria?
The basic functional unit of a skeletal muscle fiber, where contraction occurs, is called this.
What is a sarcomere?
This deeper skin layer contains blood vessels, nerves, hair follicles, and many glands.
What is the dermis?
The axial skeleton includes the skull, vertebral column, and this structure that protects the heart and lungs.
What is the rib cage, or thoracic cage?
Often called the “powerhouse of the cell,” this organelle produces much of the cell’s ATP.
What are mitochondria?
This domain contains prokaryotes that are genetically distinct from bacteria; many species live in extreme environments, although not all do.
What is Archaea?
During muscle contraction, thin filaments of this protein slide past thick filaments of myosin.
What is actin?
This vitamin can be produced in the skin when ultraviolet light exposure activates a precursor molecule.
What is vitamin D?
These specialized cells break down old or damaged bone tissue during bone remodeling.
What are osteoclasts?
This organelle contains digestive enzymes that break down wastes, damaged cell parts, and large molecules.
What is a lysosome?
In the common six-kingdom model, this kingdom includes multicellular, heterotrophic eukaryotes that usually move and do not have cell walls.
What is Animalia?
