<span>Factors that can increase mutation rates are high and low temperatures, food additives, and UV rays. All of these answers are correct. Mutation rates in genes vary depending on many environmental effects. UV rays, along with varying temperatures, can cause mutations during cell division due to the damage they impart on the cells that are dividing. Dangerous food additives are believed to cause mutations, as seen in animal studies (ie. aspartame causing cancer in rats).</span>
The best summary of the process of natural selection will be provided bythe option D that is genes are always passed from parent to offspring . Hence , out four inheritance is one of the option in the given question that is gene are passed from parent to offspring .
The answer is difference in density. We know that the high central density suggests the earth must be rich in nickel and iron and that much of the core must be liquid. This lower-density air then rises and is replaced by cooler, higher-density air. The result is atmospheric circulation that drives the weather and climate through redistribution of thermal energy.
Answer:
A) the diameter of the helix
Explanation:
This is was measured during the 3D structure of DNA proposed by James Waston and Francis Crick in 1953. The x-ray diffraction showed crossed shape of the X-ray films.The DNA appeared as two double strands structure.
The diameter of the DNA double helix is 20 Armstrong.
This diameter is constant because of the complementary pairing of bases.( purines with pyrimidines)
