If we consider the positive possibility of false negative and false positive for tests on individual chicken. Veterinary have developed a procedure to determine if the H6N2 virus is present in the flock of chickens. The veterinary select ten chickens randomly from the flock and perform Elisa test of the blood sample from each and every one of the ten chickens.
By the conclusion of the veterinary if the H6N2 virus presents in flock if three out of ten chickens have positive Elisa.
Gene mutation
I found this in nature.com, “If a mutation occurs in a germ-line cell (one that will give rise to gametes, i.e., egg or sperm cells), then this mutation can be passed to an organism's offspring. ... Germ-line mutations occur in reproductive cells (sperm or eggs) and are passed to an organism's offspring during sexual reproduction.”

Explanation:
Hemophilia is a disease that is characterized by an abnormal blood clotting process. There are many different proteins that are involved in the clotting process and a single mutation or change in one of them could result in serious effects. Hemophilia is characterized by an abnormal version of one of the many proteins involved in the clotting process, the proteins that are commonly affected are the coagulation factor 8 or 9 (VIII or IX). These abnormal proteins are caused by a mutation in the gene (within the DNA) that codifies for the production of each protein. In other words, a mutation in the part of the DNA, (gene F8) will lead to a dysfunctional coagulation factor VIII and a mutation in the gene F9 will lead to a dysfunctional coagulation factor IX. Importantly, these mutations could be inherited and could cause hemophilia. Therefore, an error in the DNA and subsequently, an error in the protein will cause hemophilia. Finally, it is important to mention that there are other types of hemophilia that are not caused by the above-mentioned mutations, such as acquired hemophilia.

<h2>Answer:</h2>
<u>The objects that allow humans to access ground water are:</u>
- <u>A spring</u>
- <u>a well drilled into an aquifer
</u>
- <u>a well drilled below the water table</u>
<h2>Explanation:</h2>
Access to ground water can be gained if we dig a well or use any source that can provide us an access below the water table. A water table is the level below which the ground is saturated with water. So above the saturation level we cannot gain access to water therefore we must go below it. A spring springs from ground below water table and the same thing occurs for well or an aquifer if it is below the water table..
