QUESTION POSTED AT 17/10/2019 - 09:01 AM

Cranberries and grapes may have therapeutic value. A cranberry company obtained the patent for a process to extract the oil from cranberry seeds. According to the patent, this oil can be used to treat breast cancer or to reduce its incidence. The oil can be used in drinks and foods. A grape juice company claims to have evidence that certain grapes have health benefits ranging from improving cardiovascular health to improving cognitive brain function in the elderly. These claims will be tested by the Food and Drug Administration (FDA) before the companies are allowed to market their products for “treating” ailments or “improving” health. Until then, the companies can describe that their products “help to maintain” or “support” health. Until studies support their claims, the companies cannot ascribe direct health benefits to their products. Why would the FDA perform tests when a cranberry company and a grape company have already conducted research on the same products? The FDA is the only organization that can test if health actually improves. Tests that are performed by any company which benefits financially are considered unreliable. The FDA tests give reliability to the results of improved health obtained by each company. Tests performed by the FDA follow established scientific methods, but those performed by companies do not.

Answer:

The correct answer will be option-The FDA tests give reliability to the results of improved health obtained by each company.

Explanation:

The Food and Drug Administration or FDA is a United States federal agency established to control the food safety under the United States Department of Health and Human Services.

The FDA helps control the issues related to the safety of the food and food products like dietary supplements along with pharmaceutical drugs, biopharmaceuticals, cosmetics and other products under the Acts.

In the given question the juices before released to the market are tested by the FDA as the FDA results support the results of the research performed by the company and the give the reliability to the results.

Thus, the selected option re the correct answer.

Help me please!! I've looked it up and I can't find any answers. 1. Dromedary camels in Australia 2. Comb jellyfish (ctenophores) in the Black Sea 3. Piranhas in the United States Was the introduction intentional or accidental for the things above? How did it happen? Why did the organism do well in the new environment? What was the effect on the native environment? What efforts have been made to eliminate or reduce the numbers of the organism? What is the status right now of the organism in the new environment (has it been eliminated, or does it still flourish)?

The Jelly fish became over populated in the black sea, because of over fishing, and uncontrolled agricultural runoff.

The camel was imported, for transport, and exploration. (especially for the harsh conditions of the outback)

The piranha is very confusing, and people are still trying to figure out how they got to the United states, because they are found in very small numbers across the US, but seem to thrive in California, it is believed that they were smuggled into the US.

QUESTION POSTED AT 17/10/2019 - 08:35 AM

Hemophilia is a gender-linked blood disorder in humans. The gene responsible for it is gene-linked recessive, meaning it is present on the X chromosome. When the gene is present in males (Xh), it always expresses itself, meaning that the male's blood won't clot properly. When present in females in a heterozygous condition (XhXH), the gene doesn’t express itself; but the female becomes a carrier, meaning that her offspring could have hemophilia.. When present in a homozygous recessive condition in females (XhXh), it expresses itself. One of every 10,000 persons is affected by this disease. What could be the allele frequency for this disease in the entire population?

Hemophilia's expressive gene is carried by the mother herself.  For a female child, it is impossible to have Haemophilia as one allele is being carried by father and that allele does not cause disease. In the male offspring, chances of being diseased are 50:50, as the female gene in half of the gametes will be dominant and half will be recessive. Therefore, out of 5000 male offsprings, 2500 bear the chances of getting Haemophilia. 
But in real life situation, 1 out of 10000 people is affected.

The cell walls become brittle as they dry out, and some of them collapse. The central vacuoles in the cells lose water and can no longer help support the cells.
