Acceleration is defined as the rate of change of velocity
Since velocity is a vector, it has both speed and direction.
So, if the object is travelling in a straight line at a constant speed, then it will not be accelerating. Both Magnitude and direction are constant.
However, if the object is travelling in a circle at a constant speed, then it'll be accelerating. An Object going in a circle is constantly changing it's direction, which means velocity is changing, so there is an acceleration caused by a net force.
Hope this Helps :)

Explanation:
it get recycled again when it becomes old
Our fingerprints are like our own dna that makes up our identity. Our fingerprints are like a serial code which can be scanned like the iPhone.
The water enters the xylem first by osmosis. Water moves from the soil to the root hair cell down a water potential gradient, and to the root cortex cell from a higher water potential to a lower water potential, this process will be repeated until water enters xylem. Because transpiration is occurring in the leaf, water is lost so there is a lower water potential inside the leaf. Osmosis moves water from the xylem to the leaf because the xylem has a higher water potential. Water moves from the xylem to the cells of the leaf. This pulls water up the xylem via cohesion which is the process of water molecules attracting each other and sticking together. Water does not fall down the xylem as here is adhesion which is the process of water molecules sticking to the inside of the xylem.
Answer:
B. sheet of connective tissue that attaches a muscle to another muscle or bone.
Explanation:
The aponeurosis are mainly made of collagen fibers and works as an insertion to some skeletal muscles. The aponeurosis fibers can connects muscles to the bone or with another muscles connecting the aponeurosis fibers among themselves.
