Imagine if mermaids are real. What are their biological and Physical demands (LOCOMOTION, BREATHING, and THERMOREGULATION)?
Due to human activities more carbon dioxide (CO2) is dissolving into the air, the ocean takes up
more CO2 and becomes increasingly acidic. Increased ocean acidity makes it more difficult for
marine animals to produce their calcium-rich hard parts. Explain three types of invertebrates that are
likely to be adversely affected by an increase in ocean acidity.
In sharks hormones regulate which of the following functions?

Growth
Stress responses
Lactation
The lymphatic system
Smell
Defecation
Osmoregulation
Reproduction
