What is capillary action? describe how capillary action shown by water is useful for plants and animals on earth.

Look Below

Explanation:

Capillary action is adhesion of water. In plants, capillary action allows water to move from the roots to leaves. In animals, capillary action plays a role in respiration where oxygen-poor blood oxygenates in the capillaries.

The capillary action of water can be defined as the property of water by which it travels through the tube in upward direction which is opposite the gravity.

Explanation: This property of water is due to adhesion, cohesion and surface tension of water which allows it to climb through the tube. This property allows the plants to uptake water from the soil.

The water also moves against the gravity in the body of plants and animals with the help of capillary action.

i think its 100

i hope this !

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
