Answer:
The answer is the first option, vacuole.
Explanation:
The name vacuole has its origins in the Latin word vacuus meaning 'empty' and this unfortunately is how vacuoles appear in many slide preparations and photographs. The fact that vacuoles are fluid filled and that different vacuoles within the same cell can contain different chemicals is not normally visible.
Answer : The correct option is, (D) Surface tension is caused by cohesion between water molecules on the surface.
Explanation :
Surface tension : It is caused by the cohesion between water molecules on the surface or we can say that it is a tension of the surface of liquid caused by the attraction of the particles which are present on the surface layer by the bulk of the liquid, which tends to minimize surface area.
And due to the surface tension phenomena the shape of the water molecule tend to assume a spherical shape to attain the minimum surface area.
Hence. the correct option is, (D) Surface tension is caused by cohesion between water molecules on the surface.
A car traveling in a straight line at a constant speed has a constant velocity, but if the car turns around a curve in the road then the velocity changes, even if the speed stays the same. Or a car that is changing in speed, even if it continues in the same direction, has a changing velocity.
