Answer:
Leaching of nutrients occur.
Explanation:
NPK fertilizers are applied to the field all over the world because it has a good effect on the growth and development of plants but it has also some environmental effects such as leaching which pollutes water bodies whereas natural compost is good for the plants as well as for the soil organisms but its breakdown is very slow and it is not readily available to the plants. Lime is also very good for the soil having low pH because lime is basic in nature and it increases the pH of the soil.
Reproductive strategy is described into r-selection strategy and K-selection strategy. When an organism reproduces slowly and has only one offspring each time it reproduces, this organism is classified as the K-selected organism. Examples of K-selected organisms are elephants and humans.
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:
Explanation:
Muscle contraction is stimulated by the movement of an action potential moving along a nerve fiber to the muscles. This event follow some series of process before being stimulated.
1. The impulse arrives at the synapse and travels through the transverse tubules.
2. The muscle impulse reaches the sarcoplasmic reticulum and calcium is released.
3. Calcium floods the sarcoplasm and binds to troponin molecules leaving active sites.
4. Tropomyosin molecules bind to exposed active sites, linking actin and myosin.
5. Thin filaments are pulled over the thick filaments.
6. The muscle fiber shortens and contracts.
