1.) Particles in a solid have fixed locations in a volume that does not change. • Solids have a definite volume and shape because particles in a solid vibrate around fixed locations.
2.) It's a process called sublimation. The easiest example of sublimation might be dry ice. Dry ice is solid carbon dioxide. When you leave dry ice out in a room, it just turns into a gas.
The. Answer. Is. B
The tertiary consumer will receive 500 calories.
Calories produced by the producer = 500,000
The flow of energy through different trophic levels is 10%
After producer comes the primary consumer followed by secondary consumer followed by tertiary consumer.
Energy reached to primary consumer =
= 50000 calories
Energy reached to secondary consumer =
= 5000 calories
Energy reached to tertiary consumer =
= 500 calories
Therefore, the tertiary consumer will receive 500 calories.
The correct answer will be option-A
The respiratory system is the series of organs which is links the internal gases with atmospheric gases that is it is responsible for the exchange of gases in the animal kingdom.
The respiratory system involves the intake of oxygen and exhalation of carbon dioxide as a waste product.
The primary organs involved in the respiratory system are the lungs which along with the circulatory system transports the oxygen to every cell of the body.
Since the respiratory system along with the circulatory system allows the transport of oxygen to every cell therefore, option-A is the correct answer.
