The answer requires looking at the meaning of the words 'theory' and 'law'. The formal definition of a theory is that it is a comprehensive explanation of a observed phenomenon supported by a lot of evidence. Law is a fact that is bound to be true in nature, example Newton's second law. However, a theory is subjected to continuous refinements based on the several new findings that happen with time. These refinements make the theory appear incomplete. As with the theory of evolution, a lot of research work is being put to understand the complex phenomenon of genetic inheritance of traits of behaviour. Unless there are evidences from nature for all the aspects of evolution in theory, it'll remain a theory and not become a law.
Answer is A) Yes, if scientists decide that enough evidence supports the theory.

The agent that kills bacteria is called bactericidal. Bactericidal agents act directly by destroying the present bacteria. It is also different from bacteriostatic, because bacteriostatic means the inhibition of the spread and growth of bacteria only.
Answer:
1) Crossing over
2) Independent assortment.
Explanation:
Gametes are formed resulting from the process of meiosis where the gametes get half of the original number of chromosomes. One phenomenon that happens during the prophase 1 of Meiosis and leads to the genetic diversification is crossing over. In this process , Here, homologous chromosomes pair up and exchange information present on genes from one another. When information is exchanged, it leads to the diversity of genetic data.
The second way of increasing genetic diversity is independent assortment that takes place during metaphase 1. In this process chromosomes from both father and mother cells align on equatorial plate of the cell in an independent manner. This means that some gamete can have 1 of many different chromosomal combinations.
This reshuffling of chromosomes during independent assortment enhances the genetic diversity of any organism and this also explains why kids of same parents can look or behave very different.

<span>The breakdown would be dacryo-cysto-rhino-stomy. Dacryo means a combining form denoting tears. Cysto denotes the sac. Rhino means nose. Stomy means surgical opening. Therefore, this means to surgically restore tears into the nose from the lacrimal sac when the nasolacrimal duct isn’t working.</span>
