Describe the motion shown in the lines
Bogdan [553]

Answer:

Solution

For figure (a)

During interval AB Velocity is +ve, so the particle is moving in +ve direction, but it is slowing down as acceleration (slope of v-7 curve) is negative.

During interval BC Particle remains at rest as the velocity is zero. Acceleration is also zero.

During interval CD Velocity is -ve, so the particle is moving in -ve direction and is speeding up as acceleration is also negative.

For figure (b),

During interval AB Particle is moving in +ve direction with constant velocity and acceleration is zero.

During interval BC Particle is moving in +ve direction as velocity is +ve, but it slows down until it comes to rest as acceleration is negative.

During interval CD Velocity is -ve so the particle is moving in -ve direction and is speeding up as acceleration is also negatived

Answer:

Option-1 and 3

Explanation:

Cadherin is the protein complex present in the cell which is responsible for the sticking together of cell in tissue-like in the skin. The cadherin junctions allow the communication between the cells and the loss of the cadherin could cause cancer.

The cadherin junction is involved in the signalling pathway in the cells like in the Rho GTPase signalling, Ras signalling and many others which shows that they are responsible for the biological processes in an organism.

Thus, Option-1 and 3 are correct.
