<span>Science knowledge relies on experimental and observational confirmation. Where data is incomplete, new or improved data may well lead to revision of accepted science explanations. In situations where observations are fragmentary, it is normal for scientific ideas to be incomplete, but this is also where the opportunity for making advances may be the greatest.The core ideas of science have been subjected to a wide variety of confirmations and are therefore unlikely to change in the areas in which they have been tested. </span><span>Science knowledge may change due to the development of new techniques for observing investigations (including new technologies), and also through new ways of thinking or framing the questions asked.</span>

ANSWER OF 1ST QUESTION -
1) it protects the nucleic acid from digestion by enzymes, 2) contains special sites on its surface that allow the virion to attach to a host cell, and 3) provides proteins that enable the virion to penetrate the host cell membrane and, in some cases, to inject the infectious nucleic .
ANSWER OF 2ND QUESTION -
Mutations can produce viruses with a reduced pathogenicity, altered host range, or altered target cell specificity but with intact antigenicity. Such viruses can sometimes be used as vaccine strains.
Answer: Option (d) is the correct answer.
Explanation:
The collisions between calcium hydroxide and carbon dioxide can be speed up by decreasing or reducing the volume of container.
This is because when we decrease the volume then there will be more space available for particles to interact or collide.
Therefore, number of collisions will increase as a result, the product formation will be fast.
Thus, we can conclude that out of the given options, reduce the volume of the container best describes the a way to speed up the collisions between calcium hydroxide and carbon dioxide molecules to produce calcium carbonate faster.
Answer:
The Supreme Court of the United States ruled in Myriad Genetics, Inc. that human genes cannot be patented in the United States.
Explanation:
since DNA is a "natural product" Because there is no new intellectual property created when a gene is discovered, the Court determined that patents cannot be granted.
