its the same
The platypus's spur is sharp and attached to a venom gland in the platypus's thigh. The echidna's spur is blunt, and is not attached to a functional venom gland.
Spur gears are cut with straight teeth. They can only transmit rotation between parallel shafts, and are relatively economical. Bevel gears have teeth cut on an angle. They transmit rotation between non-parallel shafts. Helical gears have curved teeth. They are generally quieter than spur gears, but are generally more difficult to make and more expensive.
The rooster will grow a spur about 2 inches above the back claw and inside the leg. Hens do not grow spurs.
There are no similarities, apart from the fact that the spur is located on each animal's hind legs. The platypus's spur is sharp and attached to a venom gland in the platypus's thigh.The echidna's spur is blunt, and is not attached to a functional venom gland.
The flow difference in gear compares because it spurs for 5 hours.
Spur gears give 180 degree drive, and worm gears give 90 degree drive.
A valley is a low area of land between mountains or hills, often with a stream or river running through it. A spur is a narrow ridge that extends from the main mountain ridge or peak. Valleys are typically wider and deeper than spurs, and are formed by erosion from water or glaciers, while spurs are formed by the intersection of two valleys.
