Answer:
D)Gas particles move rapidly and have space between them.
Explanation:
Matter exists in three states namely: solids, liquids and gases. The particles contained in these three states are different from one another. In the gaseous state, the particles are FAR APART from one another i.e. space exists and they move at a very fast rate in contrast to the particles of a liquid, which have less space and move slower.
This rapid movement of gas particles within a less restricted space accounts for the reason why gaseous substances DIFFUSE more quickly than liquids.
Answer: biological adaptation
Explanation:
lungfish's lung is a biological adaptation. A biological adaptation is a physical change in an organism that develops over time. Like all fish, lungfish have organs known as gills to extract oxygen from water. The biological adaptation of the lung allows lungfish to also extract oxygen from the air.
I hope this helps :).
The principle of radiation protection is to trigger deterministic and stochastic effect.
Explanation:
The main aim of principle of radiation is to prevent the deterministic effects of radiation and reduce the risks of stochastic effects.
There are three general principals of radiation used for dealing with ionising radiation are Justification, Dose limitation and Optimization.
The three basic radiation principles are time, distance and shielding.
The risk of exposure to radiation is measured using the conventional unit rem or SI unit (sievert).
