Answer:
D)radioactive waste is produced
Explanation:
Radioactive waste is a dangerous waste material which contains radioactive substances that are bad for health. These waste are produced in the nuclear reactor for the production of electric energy. Radioactive substances cause many diseases in human such as burning of skin and cancer. It is a non-biodegradable substance which remains in the soil for long periods of time and emit alpha, beta and gamma radiations.
Answer:
True
Explanation:
<em>Conclusions made from scientific research or understanding can always be challenged by anyone with new ways of observing and with different interpretations. This is the essence of the repeatability or reproducibility of scientific experiments.</em>
Scientific research must be reproducible and if the earlier conclusions or understanding is found to be somehow inadequate with overwhelming evidence, they are modified or even changed completely in order to accommodate new facts.
Hence, the emergence of new ways of observing different interpretations can lead to new/different conclusions from the same research. If the new conclusions gain enough evidence, it becomes the new theory.
Stored in the laboratories at the centers for disease control and prevention and a Russian laboratory in Siberia are the only two place in which Smallpox virus remains.
<h3>What is smallpox?</h3>
Variola major or Variola minor are the two virus strains that cause the contagious sickness known as smallpox. The variola virus (VARV) agent is a member of the genus Orthopoxvirus. The World Health Organization confirmed the illness's universal eradication in 1980 after the last naturally occurring case was diagnosed in October 1977, making polio the only human disease to have achieved this feat.
Fever and vomiting were among the disease's earliest signs. This was followed by the development of mouth ulcers and a rash. The skin rash developed into the typical fluid-filled blisters with a dimple in the middle over a period of days. The scars were left after the lumps scabbed over and dropped off. People could contract the illness from contaminated things or from one another. Prevention is through the vaccine for smallpox.

Answer:
Meiosis I: in meiosis I there is pair of chromosomes called homologous chromosomes which are to be seperated so one of that two chromosomes right pole of the cell and the second one goes to the left pole so each pole gets a chromosome with two sister chromatids.
Meiosis II: While in meiosis II homologous pair is not formed and single array of chromosomes are arranged to form metaphase plate as formed in Mitosis so, when the spindle fibres contracts each sister chromatids went to their respective poles.
