True breeding refer to an organism that always passed a certain genetic to its offspring.
Some advantages of true breedings are :
- Diminish the probability of Genetic Mutation
- Reduce the risk of Genetic Extinction
- If used in industry, it could be used to produce/bred the exact type of products
An oxygen atom alone will have 6 valence electrons (outermost electrons). A hydrogen atom each has 1 electron in its outermost shell to share with the oxygen. For oxygen to have a filled outer shell, it will take one electron from each of the two hydrogens into it's outer shell. This means, the number of electrons in its valence shell will be the original amount of electrons oxygen has by itself plus 1 electron from each hydrogen atom. This will form a water molecule
Is there any Options for the answers?
