Considering the atmosphere of the primitive earth to have contained water vapor, carbon dioxide, carbon monoxide, methane, and ammonia and/or nitrogen, then in the presence of an energy source, such as sunlight or lightning, a number of small molecules like hydrogen cyanide, HCN, are formed.
The Name Of An Isotope 42 protons and 50 neutrons is Molybdenum
Explanation:
Molybdenum is famous as a silvery –white metal. It is very highly resistant as well as ductile metal. The melting point of molybdenum is very high. The atomic number of this element is forty-two. It is used for production of alloy.
We can use it for making engine parts, filaments of heater, circuit board and many more. it is sold and produced as a brown powder. It is 54th most common which is present in earth’s crust.
Genes B and C with 10% recombination frequency are closest to each other. Because recombination happens at random, the distance between genes that are farther from each other creates higher recombination frequency. A low recombination frequency of 10% means the genes are closest to each other. The short distance between the two genes allow fewer recombination to happen, thus the frequency is low.
