Sends chemical messages (hormones)
Processes sensory information

Match the reproductive structure or hormone to its primary role.
1. Estrogen A. Responsible for male physical traits and sperm production
2. Testes B. Prepares and maintains the uterus for pregnancy
3. Progesterone C. Female sex hormone that develops reproductive traits
4. Testosterone D. Male reproductive organ that produces testosterone

The endocrine system manages long-term changes like growth and energy use. It consists of specialized organs called _________________, which produce chemical messengers called _________________. These chemicals are released directly into the _________________ to travel throughout the body.

Maya is playing in a championship soccer game. During a play, she successfully "heads" the ball to a teammate. Later, she falls and lands on her back, but her spinal cord remains safe because of her vertebrae.
Maya's skeletal system helped her play because her joints / skull / rib cage / spine allowed her legs to move and kick the ball. When she headed the ball, her brain was protected from the impact by her joints / skull / rib cage / spine. As she ran, her lungs and heart were kept safe within her joints / skull / rib cage / spine.

Match the system to its defining function:
: Creates offspring to ensure species survival.
: Provides a rigid framework for the body.
: Coordinates response to external stimuli.

The muscular system helps maintain homeostasis by regulating temperature. When you are cold, muscles contract rapidly, which is called shivering. This process generates heat / waste / blood / food to warm the body. Additionally, muscles help pump heat / waste / blood / food through the vessels and move heat / waste / blood / food out of the digestive tract.

A. Igneous
B. Magma
C. Metamorphic
D. Volcanic

A. Weathering into sediments, then eroding.
B. Compacting under pressure and cementing.
C. Changing shape under heat and pressure.
D. Melting completely into magma, then cooling.
(6.10C)
As the rocks in the badlands get exposed to rain and wind, sediments are formed. Over many years, these sediments pile up and get pressed and cemented together. What kind of rock is formed?
