Answer:
Explanation:
The gases and dust particles thrown into the atmosphere during volcanic eruptions have influences on climate. Most of the particles spewed from volcanoes cool the planet by shading incoming solar radiation. The cooling effect can last for months to years depending on the characteristics of the eruption.
They bombard nuclei with high-energy particles, such as protons, neutrons, or alpha particles.
Explanation:
Scientist are performing artificial transmission by bombarding atomic nuclei with high energy particle such as neutron, proton and alpha particle. Nucleus decay is an example of transmutation which occurs naturally. Elements with electronic number which is greater than 92 is called trans uranium element.
All trans uranium elements are radioactive which is found is nature. Some transmutation requires particles that are moving at extremely high speed. Scientist have produced nearly 3000 different isotopes.
Answer:
Different Swimming strategies used by Osteichthyes and Chondrichthyes are accounted to their different anatomy and body organs. ... though, bony fishes possess the swim bladder and fins, which help them to swim even without moving their body.
Explanation:
10; 2%
Of the chemicals that fall under the TSCA 10% have been tested for toxicity and 2% have been tested for endocrine, nervous, or immune system damage.
The Toxic Substances Control Act (TSCA) is a law issued by the United States Congress and used by the Environmental Protection Agency (EPA) to demand for documentation and testing requirements, and restrictions associated with chemical substances. Other substances such as foods and drugs are mainly removed from TSCA.
