o support this idea?
Organic molecules form in Earth's atmosphere and travel through space in meteorites.
Vesicles in meteorites and microspheres can maintain an internal environment and store and release energy like cells do.
Some meteorites contain organic compounds which may be precursors to today's living cells.
Meteorites contain full DNA molecules, which self-replicate and pass onto future generations.

Answer:

The correct answer would be the third option.

One of the hypotheses regarding the origin of life is "organic molecules from outer space".

Under this concept, it is believed that organic compounds might have come on earth through meteorites. Then these organic compounds were used as the precursors of the living cells.

Certain pieces of evidence are also found to support this concept.  

For example, scientists have experimentally proved that conditions like low temperature and high UV radiations (similar conditions as exist in outer space) can result in the production of organic molecules from simple chemical precursors as present in space.

In addition, some organic compounds have also been found in space or other star systems.

When transporting donated platelet units, what is the maximum amount of time that agitation of platelets can be stopped for
SIZIF [17.4K]

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.

If the PP of a test Protocol was 32 then the BP would have to be..
Harlamova29_29 [7]

Answer:

The correct answer would be - 120/88 or 112/80

Explanation:

Pulse pressure or PP is the difference between the top or higher number (systolic) and the bottom number (diastolic) blood pressure. Pulse pressure can find out by the systolic minus the diastolic of Blood pressure.

For example, if an individual's resting BP is 120/80 millimeters of mercury (mm Hg), the normal PP is 40 which is considered a healthy pulse pressure. So, as per the normal BP 120/80, if the pp was 32 than the bp would be 120/88 or 112/80.
