This doesn't seem like much of a biology question but more of a chemistry one :P
But to answer your question, as the temperature of the water molecules rises, the chemical bonds holding them together begin to fall apart, causing the structure of the ice to fall apart.
When water is evaporated, the chemical bonds holding the water molecules together becomes non-existent, and the water becomes a vapour in which molecules float independent of each other <span />
Answer: C. The amount of insulin in her blood is wrong.
Explanation: The pancreas is mainly responsible for production of insulin, so a change in insulin levels would indicate something being wrong with the pancreas.
Answer: Involuntary.
The Autonomic nervous system is a subdivision of the Peripheral nervous system and it is in charge of the involuntary processes in the body such as blood pressure, respiration and the heart rate. As such, its effectors are under involuntary control.
The Autonomic nervous system controls the smooth and cardiac muscles in the body as well as the glands. This is where it earns its other name, the Visceral nervous system.
Explanation:
Kinetic energy of a snowball will increase as it <span>rolls across the lawn and gains mass. We already know that Kinetic energy is directly proportional to speed. We can express kinetic energy by the formula
Kinetic energy = 1/2 mv^2
Now as the mass increases and the velocity remains constant, the kinetic energy of the snowball is bound to increase. I hope the explanation has helped you.</span>
