The skeletal system is the body system composed of bones and cartilage and performs the following critical functions for the human body:

supports the body
facilitates movement
protects internal organs
produces blood cells
stores and releases minerals and fat
Choose three of these functions and discuss what features of the skeletal system allow it to accomplish these functions.

supports the body

facilitates movement

protects internal organs

produces blood cells

stores and releases minerals

Explanation:

The skeletal system in animals helps in their movement, support and to maintain their shape.In humans ,it consists of bones,which works closely with the muscular system.unlike worms and arthropods that have hydrostatic and exoskeleton respectively, humans have endoskeleton.the bones have the following functions;

*It allows the animal move . The skeleton provides support for the body and through the flexible joints ,the body is able to move

*The skeleton protects the internal organs of the body by protecting them against impact.for examples,the ribs protect the lungs and the skull protects the brain.

*Certain cells in the bone produce immune cell and important components of the bone

*The bones also regulate the level of calcium in the blood

provides structure to the body

protects delicate organs

facilitates body movement

answer; i believe the answer is hydraulic action;

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.
