In human body, a joint is defined as a location where two or more bones meet and connect. The range of motion of joints refers to the measurement of the maximum distance and direction a particular joint can move. Most joints are connected in such a way that they allow movements in specific directions only.
The quantity of movement through a normal range for each joint is measured in degrees using an instrument called goniometer. Scientists had established standard range of motion values for most joints.
For ankle joint, downward movement of the joint, which is called plantar flexion ranges from zero to 50 degrees while the movement upward, which is called dorsiflexion ranges from zero to 20 degrees.
Answer:
true
Explanation:
stars can change bc Stars change over time. ... It is in the clouds of dust and gas that stars are born. As more and more of the gas (which is mostly hydrogen) is pulled together by gravity into a cloud, the cloud starts to spin. The gas atoms start to bump into each other faster and faster.
From it's environment and from traits from other parents.
Answer:
Artificial selection, also called "selective breeding”, is where humans select for desirable traits in agricultural products or animals, rather than leaving the species to evolve and change gradually without human interference, like in natural selection.
I'm not sure how you compute the density of agcl using the length of a unit cell edge measure of 555 pm.
But as per online research, the density of AgCl is 5.56 g/cm³
AgCl is the chemical formula of silver chloride. It<span> is easily synthesized by combining aqueous solutions of silver nitrate and sodium chloride.

AgNO₃ + NaCl → AgCl↓ + NaNO₃
