A theory is why something happens and a law is how something happens.
Explanation:
Whenever scientists or people studying scientific disciplines face any scientific question, they try to solve it through proper scientific method. Two of the most important steps of scientific methods are to propose a theory as an answer of the question and after it formulate a law if it can be formed.
In simple terms we can think of a theory as an logical answer that why a certain phenomenon occurs. On the other hand a law is a statement that shows how a phenomenon occurs and it can help in predicting about the phenomenon. Laws are relatively general as compared to theory because theory is logical and well reasoned explanation about a certain happening.
A theory grows into a law when several group of people work on the same question and find same answer in such a way that it is universally approved. Theories can be revised after repeating experiment or condition however scientific law can never be proved wrong and it remains same.
For example: Darwin's theory called Neo- Darwinism in which he said that living organisms can be produced from non-living organism was disapproved by scientists after careful experimentation. It explained the reasoning that why living organisms can be produced from non-living organisms however if it had been proved by all scientists it would become a law which just explains that how living organisms are produced from non living in a general one or two lines statement. For example: Newton's law of motion.

Do you mean sediments???
the type of rock formed from sediments is called sedimentary rocks
viruses are tiny bundles of genetic material which is carried in a viral coat.
<u>Explanation:</u>
- The virus is generally a parasite that needs a host to become active and to reproduce. It cannot reproduce without the host.
- The tiny bundle consists of genetic material and protein. The virus consists of capsid and nucleic acid. This capsid is said to be the protein coat.
- This capsid consists of either RNA or DNA. virus replicate themself within the host body by using its genetic material along with the mechanism of the host.
- Thus after replicating the virus need to get out of host cell, It is performed by two types budding or lysis( bursting the host cell ).
Answer:
A: yes
Explanation:
B: Sample three is a mixture of the suspect and victims. Putting it simply, if you line up the victims DNA and remove it from sample 2 you are left with a sample of DNA that is identical to the suspects.
Answer:
The correct answer is - characteristics of all vertebrate animals.
Explanation:
Innate immunity is the first line of the immune system that comes with birth whereas adaptive or acquired immunity is the immunity that comes throughout life by experiencing or developing the immune system. Adaptive or acquired immunity is the immune response that comes through cell-mediated responses whereas innate immunity is the immune response that includes sweat glands and secretion from the skin. innate immune responses also include digesting and killing bacteria by the saliva, enzymes, lysozymes.
The only characteristic among these that present in both is that they both immune systems found in all vertebrates.
