Answer:
The correct answer would be Pp.
The genotype of one parent is PP. Thus, it will produce only one type of allele, that is, P.
Similarly, the genotype of another parent is pp. Thus, it will produce only one type of gamete, that is, p.
The cross would produce offspring with only one type of genotype, that is, heterozygous Pp.
The phenotype of all the offspring will be purple as it is a dominant trait.
Answer:
Magnesium hydroxide Mg(OH)₂ is the formula for the antacid. Commonly known as milk of magnesia.
This antacid should be taken at bed time or one hour after meal. Once a day.
The routine medication should have at-least one hour gap with the antacid.
If sally develops diarrhea then the antacid should be discontinued.
Lifestyle changes that could help Sally's bowel and gastric conditions are:
- High fiber diet.
- Increased Water intake.
- Regular exercise.
- Less spicy died.
- Taking meals at-least 3 hours before bed time.
- Wearing loose fitting comfortable clothes.
Explanation:
- following the symptoms it is assumable that Sally is suffering from GERD (Gastroesophageal reflux disease) which has resulted in constipation.
- GERD is a condition when the stomach acid of a person moves into the esophagus due to incomplete closure of the lower esophageal sphincter .
- Reflux of the stomach acid results in heart burn.
- The best way to relieve this condition is to take an antacid having a bicarbonate, or hydroxide formula which will react with the stomach acid and neutralize it or a proton pump inhibitor which would check the production of stomach acids.
- In Sally's case GERD is accompanied with constipation so she needs a antacid as well as laxative which will ease the bowel movement.
- A proton pump inhibitor will not be a good choice because it might aggravate the constipation thus Milk of magnesia or any other antacid with magnesium hydroxide with a chief component should be prescribed.
- Magnesium hydroxide is a laxative that acts as a mild antacid.
- Milk of magnesia has been reported of having diarrhea as a side effect, so the medication should be discontinued if Sally suffers diarrhea after taking the medication.
- GERD is best treated with lifestyle changes that include high roughage in diet, water intake, and physical exercise. These prevent the built up of acid in stomach and maintain the intestinal peristalsis thus regularizing the bowel movement and relieving acid acccumulation.
Answer:
Option A
Explanation:
Sperm undergo more mitotic cellular divisions than egg and therefore have a higher risk of developing a spontaneous mutation.
As noted from the explanation given above...in the process of development in males, the sperm cells always undergo many mitotic cellular division throughout their life increasimg the males' chances of undergoing spontaneous mutations as compared to the females during development where it gets to a certain point in their lives where they stop producing egg cells after the once division.
Thus, the continuous divisions undergone by the sperm cells acquire more spontaneous mutations on the cell that produces this lycantrophy trait.
Answer:D. tapeworms live inside a goats body in a close relationship the goat.
Explanation:
In parasitic relationships,the parasite lives on the host and benefits from the host while causing harm to the host .the host does not benefit.the parasites are usually in close relationship with their host as their food source are substances of the host organisms.
The parasite may live in the host , these are called Endo-parasites.
The parasite may live outside the host, these are called ecto-parasite. In this example, the tapeworm is an endo-parasite that lives in the digestive tract of the goat. It absorbs digested food in the intestine through it's body surface.
In predator and prey relationship, the predator usually has to hunt for the prey and feed on it. It may kill it first or may not
Answer:
The normal body temperature for humans is 37 degrees Celsius. Most of the enzymes of a human's bodywork best at this temperature. If an enzyme was discovered which works best at 39 degrees Celsius, then it means that the enzyme works at elevated temperatures for events which require slightly higher temperatures.
The enzyme will most probably work for overcoming fever or for reducing the temperature of the body after exercise.
