<span>The question is asking us to complete the sentence "If, after extensive research, the expected observations predicted by a theory fail to materialize, then the theory" and the way we can complete it is by saying that the theory is likely wrong - the theory must then be rejected and a new theory should be proposed, one that will lead to a new hypothesis which then should be tested. </span>

ExtremeBDS [4]

Answer: B - Were your parents or grandparents ever diagnosed with Huntington's disease?

Explanation: In autosomal dominant disorder, affected offsprings must have an affected parent. Unaffected parents do not transmit the disease.

Since the disease is caused by a dominant allele, the young man would only be at risk of having Huntington's disease if his parents or grandparents had ever been diagnosed with the disease. He needs not to worry if his parents or grandparents had never been diagnosed with the disease.

His cousin who has been diagnosed with the disease could have inherited the allele from his other parent.

Answer:

high clean-energy startup costs

Explanation:

Protecting the environment means improving its sustainability and reducing pollution to the barest minimal. This utterly means terminating every activity that contributes to pollution in the environment, including the source of energy. The most widely used source of energy is the non-renewable source e.g. coal, fuel, etc.

These source of energy, however, release pollutants in form of greenhouse gases, into the environment. One way to eliminate the use of non-renewable source of energy is to adopt the use of renewable sources e.g. solar energy, wind etc. However, one major setback to doing this is the high production cost involved.

Although these sources of energy (renewable) are referred to as green or clean, but they have really expensive startup costs and are unaffordable most times.

We can change our fooding style. Instead of taking starchy, fatty, oily food, we can take some best fruit and vegetables for fat loss in our diet like cucumber, watermelon, grapes etc. Eating these fruits during hunger can avoid our hunger and as they do not contain any of the fat gaining factor, encourage body to utilize the stored fat. Eating these fruits with regular early exercise can obviously help you loose your fat.
