Answer:
Fungi indirectly help the fishes by providing digested organic nutrients to their prey insects.
Explanation:
According to the given information, fishes are predators of insects. These insects feed on dead leaves. The insects are not able to digest the cellulose of dead leaves. Fungi breakdown the dead and decaying leaves and digest the complex molecules such as cellulose into simpler organic nutrients which in turn are consumed by insects.
If fungi do not decompose the dead leaves, insects would not be able to derive the organic nutrients from them. A shortage of food supply to insects would starve them. Unavailability of prey insects would starve fishes. Thereby, fungi indirectly benefit the fishes to obtain their nutrition from the insect.
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.
<h2>Koch's Postulates.</h2>
Explanation:
The next step should be isolate the microorganism from the mice and check if it is identical to the original microbe.
According to Koch's postulates, a microbe can be considered as a causative agent of a disease only after all the following are established:
- The microorganism should be present in all the organism suffering from the disease.
- The isolated microorganism should be grown in pure culture.
- The organism grown in the culture should be reintroduced in the susceptible but healthy host.
- Finally the microorganism must be re-isolated from the experimental host an cultured to see whether it is identical to the original specific microorganism.

Answer:
C. More than 5 fingers/toes on each hand/foot
Explanation:
According to the given information, polydactyly is an autosomal dominant trait which means that the phenotype would be expressed in both homozygous dominant and heterozygous dominant genotype.
The given genotype is heterozygous dominant. The individuals with heterozygous dominant genotype would exhibit the polydactyly and would have more than 5 fingers and toes on each hand and foot.
