What is artificial selection? Provide an example that you can think of.
Example: Chihuahuas and Great Danes are both descended from wild wolves and were bred by humans for their specific characteristics.
Artificial Selection: the identification by humans of desirable traits in plants and animals, and the steps taken to enhance and perpetuate those traits in future generations.
A goby fish and snapping shrimp live in a sandy burrow built by the shrimp. Because the shrimp is so blind, it keeps one of its long feelers on the goby. When danger approaches, the goby warns its partner with flicks of its fins, and both partners retreat to their home. This is an example of ______ (Mutualism, Commensalism, Parasitism)
Mutualism (they both benefit!)

With this type of fracture, a bone is broken into multiple pieces, does not break through the skin, and may require a metal plate and screws to be surgically implanted to heal properly.

What is the main function of these body systems?
1. Integumentary System
2. Nervous System
3. Muscular System
1. to waterproof, cushion and protect the deeper tissues, excrete wastes, regulate temperature and is the attachment site for sensory receptors to detect pain, sensation, pressure and temperature. Also provides vitamin D synthesis.
2. to coordinate the body’s response to changes in its internal and external environment
3. works with the skeletal and nervous system to produce movement, also helps to circulate blood through the human body
