The radiologic
skeletal survey is most useful tool for detecting occult trauma fractures in children
younger than 2 years old. A current policy states that skeletal survey is
mandatory in all cases of suspected child abuse because younger
children are easier to lift, shake, throw, pull and fall. Moreover, occult fractures can be detected by bone scan
though; bone scan is not specific for fracture but still most useful in
detecting occult rib fractures.
At that time, plate tectonic movements shoved all of the continents into one big super continent. After that time, plate movements started to break up this super continent until the continents eventually reached their present configuration.
Answer:
C. Releases hormones to regulate the endocrine system
Explanation:
Proteins function optimally at a specific temperature. So if you get too hot or too cold, biochemical reactions in your body start to function less well. If the situation becomes extreme enough, they can cease to function well enough to sustain life.
Warm-blooded animals have an advantage over cold-blooded ones in that their bodies automatically try to maintain the optimal termperature for things in their bodies to function. Cold-blooded animals depend on the environmental temperature to do this for them. That's why reptiles are very sluggish when they're cold, but will "wake up" when they get warm.
The cost to this benefit is that metabolically, warm-blooded animals require a lot more fuel to run their bodies. It's very energy-intensive to maintain a constant body temperature. Cold-blooded animals require far less fuel than warm-blooded ones relative to their size.
The way that proteins operate in a specific temperature is also true of the pH in your body which is also very tightly maintained.
