Answer: Thermal energy refers to the energy contained within an object that changes its temperature. Heat is the energy of thermal energy. A chemical change happens when one substance and another substance form into two or more different substances.
B, cold with a high salt content, I believe.
Since density is mass divided by volume, adding salt would increase mass.
Temperature is related to kinetic energy and the distance between molecules/atoms of a substance. The hotter the substance, the more distance there is between particles.
Generally cold water is more dense. Hope i helped :D
QUICK ANSWERNatural selection leads to evolution because the traits of those who are able to reproduce influence future generations genetics and gradually lead to these passed on traits becoming the normal state of being, thus causing the species in question to evolve. If a group of people have predominantly brown hair genes and have children, then by way of natural selection the dominant gene will increase with future generations, meaning that slowly in time this group of people will evolve to have mostly brown hair genes

Frank was bitten by a rattlesnake and given anti-venom containing neutralizing antibodies. Frank will have acquired long-term artificially acquired passive immunity and active immunity naturally he will have as a result.
<h3>What is active immunity?</h3>
Active immunity occurs when exposure to a diseased organism triggers the immune system to produce antibodies against that disease.
<h3>What is passive immunization?</h3>
Passive immunization occurs when the body already receives the antibodies ready, instead of stimulating their production. The main difference is that, in passive immunization, the body does not produce memory cells, fighting the organisms only once.
With this information, we can conclude that Active immunity is when the individual's own body produces an immune response.
