24 hours is the maximum amount of time that agitation of platelets can be stopped.

<h3>What are platelets?</h3>

Platelets are pieces of very large cells in the bone marrow called megakaryocytes. They aid in the formation of blood clots that help wounds heal and to slow or stop bleeding. It can be problematic to have platelets that are too many, too few, or aren't functioning properly.

Platelets' main job is to stop and prevent bleeding. The body sends signals to platelets that direct them to the affected location when a blood artery is damaged. Adults typically have between 150,000 and 450,000 platelets per microliter of blood, which is considered normal. Less than 150,000 platelets per microliter indicate a low platelet count. People with thrombocytopenia have low platelet levels. We can bleed heavily and bruise easily if our platelet counts are low.

aev [14]

Answer:

Please find the detailed explanation/description on how to use the light microscope to view a wet mount of a protist. The 9 structures mentioned in the question are in CAPS.

Explanation:

- Firstly, the slide containing the wet mount of the protist is prepared and placed at the centre of a lowered STAGE. The STAGE CLIPS over the sides of the slide are used to hold it in place.

- The revolving turret or nosepiece is turned so that the LOWEST POWER OBJECTIVE LENS is in position i.e. directly above the sample/slide. The SCANNING OBJECTIVE LENS, the lowest objective lens with power of 4x is used initially.

- The slide is viewed through the EYEPIECE, and the image is brought into focus using the STAGE KNOBS.

- The COARSE FOCUS KNOB is turned until the protist on the slide is brought into broad focus. The FINE FOCUS KNOB is then used to bring the image on the slide into sharp focus.

N.B: The OBJECTIVE LENS should not touch the cover slip on the slide during this process.

- When the protist on the slide is clear using lowest power objective lens, the revolver turret can be rotated to allow HIGHER POWER OBJECTIVE LENS.

- Due to higher magnification of the HIGH POWER OBJECTIVE LENS, the protist might need to be refocused using the FOCUS KNOBS.

Answer:

Stomach Flu

Explanation:

Stomach flu—or gastroenteritis—is an infection of the stomach and upper part of the small intestine. Common symptoms are diarrhea, vomiting, stomach pain, and cramps. Rotavirus and norovirus, which affect millions of people every year, are often the cause. Gastroenteritis often clears up on its own, but you lose fluids through diarrhea and vomiting. Prevent dehydration by drinking water and electrolyte drinks.
