The pH level in the ocean is becoming more acidic due to an increased amount of carbon dioxide in the atmosphere. The increased acidity causes the shell of the larger crabs to
become softer than normal. What would happen to the population of the larger crabs and how does
that impact the population of sea otters?
PLEASE HELP ME

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.

you should wear a lead protective shield when having teeth x-rays
