I’m on that same question
Answer/Explanation:
Yes, hypothesis can be proven true. A hypothesis is an educated guess that has an explanation, and you can look into it more to find if it is true or not.
For example,
My hypothesis is that falcons use their sharp talons to tear apart their prey.
I can find out if it's true by observing a hawk catch it's prey. (Although that'd kinda be gross to watch)
Hope that helps and have a great day!
Answer:
Elbow joint
Explanation:
The elbow joint is a type of hinge joint formed by the trochear groove at the distal end of humerus where it fits into the trochlear notch formed by ulna and radius. The olecranon process prevents the lower arm from over-stretching.
The muscles which operate the joints are in pairs and antagonistic. The muscle that straightens the limb is called the extensor muscle.
