Answer:
C. A sports fan using player photos to sell souvenirs at games
Explanation:
The situation least likely to be fair use is a sports fan using player photos to sell souvenirs at games.
The situation that is least likely to be fair use is option C, where a sports fan is using player photos to sell souvenirs at games. Fair use allows for limited use of copyrighted material without permission from the rights holder, but in this case, the sports fan is using the photos for commercial purposes, which is less likely to be considered fair use.
On the other hand, options A, B, and D are more likely to be fair use. In option A, a journalist is using a video clip in a report on a government meeting, which could be considered fair use as it is for educational or informational purposes. Option B, where a late-night comedian uses a photo as part of a political joke, could fall under fair use as it is for commentary or criticism. Option D, where a teacher is using a photograph in a presentation to his class, could also be considered fair use as it is part of an educational setting.

was added to 9.9 ml of sterile buffer. After thorough mixing, this
suspension was further diluted by a 1/100 dilution followed by a
1/10 dilution. One-tenth of a ml of this final dilution was plated
on agar plates. After incubation, 52 colonies were present. How
many colony-forming units were present in the total 10 gram sample
of hamburger?
Answer:
5.2 × 10 ⁹ cfus
Explanation:
Using the dilution factors
0.1 ml of the final dilution has 52 colonies
1 ml will have approximately 520 colonies
10 ml of the final sample will have 5200 colonies
at 1 / 100 dilution
1 ml of the sample will have 5200 colonies
100 ml of the sample will have 520000 colonies
1 ml of the 0.1 ml + 9.9 ml has 520000 colonies
10 ml will have 5200000
at the second stage of the dilution
0.1 ml of the slurry had 5200000 colonies
1 ml will have 52000000 colonies
10 ml will have 520000000 colonies
100 ml of the initial sample ( 10 grams + 90 ml ) = 5200000000 colonies =
5.2 × 10 ⁹ cfu
not enough of a sample.
contaminated samples.
degraded samples.
All of the above.
Answer: Option D " all of the above "
Explanation: DNA can be a great source of information when used as a forensic evidence. This technique has many advantages and disadvantages when used as a source of information in case of crime.
Identical twins: There are some common fragments of DNA that is same in identical twins so it can be a difficulty in deciding the criminal.
Not enough of a sample: DNA should be present in a detectable amount to be used an sample for evidence, less than this detectable amount is a waste and cannot be used as a sample for evidence.
Contaminated and degraded sample: If the sample of DNA is contaminated or degraded then the result might be incorrect and might not be used as a sample for forensic evidence.
Hence, the correct answers are all of the above.
Answer: Nucleotide; Adenine
Explanation: RNA Nucleotide contains bases of Thymine, Cytosine, Guanine and Uracil. The Uracil base in RNA, substitute the base Thymine in the DNA base and bonds with Adenine like as seen in DNA base pairing.
Thus, during DNA duplication, the thymine at the top of the template strand of DNA is replaced with Uracil and binds with Adenine.
Answer:
The answer is Fixed Action Patterns
Explanation:
Fixed Action Patterns are fixed behaviors in certain animals which they carry out in response to stimulus. This patterns are constantly repeated and do not change for a particular species.
Animals are born with this pattern so they do not need to learn it. Fixed Action Patterns increases the fitness, survival and the reproduction abilities of the animals.
Answer:
Advantageous
Explanation:
Natural selection acts on traits that are advantageous, thus increasing chances of survival and passing on the trait.
B)Base
C) Both
