Answer:
The answer is A.
Explanation:
During logarithmic growth phase bacteria grows exponentially doubling every x minutes (x depends on the species). In this question doubling time/generation time is every 15 minutes and log phase takes 5 hours, which equals to the 300 minutes. During 300 minutes bacteria doubles 20 times (300/15 = 20) which equals 2^20. Bacteria culture has been started with 1000 bacterial cells so it must be added to the calculation therefore right answer is: 1000 X 2^20.
Answer: the carpet padding
Explanation:
Individual evidences are simply refered to as properties of physical evidence that has to a high degree of certainty for a common source. For individual evidences, the suspect is being narrowed down to a single individual. Examples include fingerprints, toolmarks etc.
In the question above, the example of individual evidence when it comes to carpet will be the carpet padding. While other options such as fiber length, dye composition and the type of fiber can still relate to other things, carpet padding narrows it down to carpet.
