Answer:allows for simple angular movement
Explanation:
d- allows for simple angular movement
It randomly happens to offspring
<span>Electrophoresis separates polypeptide chains and DNA chains
by their fragment sizes after they have been cut by restriction enzymes are
specific sites. Genetic testing involves checking genetic
disorders by evaluating DNA sequences or protein amino acid sequences. By using
restriction enzymes to cut DNA or polypeptides at specific sites, then run them
on an electrophoresis, bands will form that will help indicate whether one has an
abnormal sequence at the target site. If so, further analysis is used to
determine the sequence by use of next-generation sequencing machines</span>
Metals are known to be excellent conductors of electricity, however some metals do not conduct electricity as well as gold, copper or sliver (examples of good conductors). Metals such as lead, mercury and alloys of iron, chromium, titanium and stainless steel do not conduct electricity as good as silver, copper and gold. It is also important to note that all gases do not conduct electricity at all due to the great amount of space between its electrons.
Answer:
Normally sterilizing food using radiation does not induce radioactivity but sometimes it may change the taste, texture of the food and it may also destroy the nutrients. radiation is used to kill the harmful bacteria and to increase the shelf life. when the radiation is very energetic it alters the food structure but it does not make it radioactive. To become radioactive one has to make a nucleus unstable. ionizing radiation normally cannot do this. FDA has established maximum energy levels for radiation to prevent the treated foods from becoming radioactive. The energy levels of the rays are too low to induce radioactivity in the food. So there is no harm in consuming treated foods.
