B. An atom whose nucleus is unstable and emits particles and and energy. This is a Radioactive isotope.
The atomic nuclei of constituent atoms of the same element include the same number of protons but different numbers of neutrons. Radio isotopes are an element's radioactive isotopes. They can alternatively be described as atoms with an excess of energy in their nucleus or atoms with an unstable ratio of neutrons to protons. A radioisotope's unstable nucleus can form either spontaneously or as a result of a deliberate alteration of the atom. Radioisotope production can occur using either a cyclotron or a nuclear reactor. Molybdenum-99, which has a high neutron content, can be produced most effectively in nuclear reactors, whereas fluorine-18, which has a high proton content, can be produced most effectively in cyclotrons. Uranium is the most well-known illustration of a radioisotope that is found naturally. Uranium-238 constitutes all naturally occurring uranium with the exception of 0.7%.

True I hope this helps you with your test
False. It's been proven in many studies to cause signs of aging such as wrinkles and weaker collagen in the face.
There environmental change would only have to occur when their is a sudden change in the amount of water, which would be a larger amount of water because that’s the only reason the bullfrog would need to store more water to help this species survive. This is called structural adaptation, structural adaptations are the physical features of an organism to help survive the new environment.
Answer: Data are the information gained from observing and testing an experiment. Scientists use data to gain understanding and make conclusions. Scientists often use graphs or tables to show their data and research findings.
