Answer:

<em><u>30 units</u></em><em><u> </u></em><em><u>of </u></em><em><u>energy</u></em><em><u> </u></em><em><u>will </u></em><em><u>be </u></em><em><u>available</u></em><em><u> </u></em><em><u>to </u></em><em><u>primary</u></em><em><u> </u></em><em><u>predators.</u></em>

Explanation:

Using 10 % law i.e at each step 10 % of energy is transferred to the next trophic level at the rest of either consumed or lost to environment..

so plants have = 3000 units

herbivores = 10% of 3000 = 10/100 × 3000

= 300 units

so primary predators will have = 10% of 300

= 10/100 × 300 = 30 units

<h3>What is Blood Transfusion?</h3>

Intravenously putting blood components into a person's circulation is known as a blood transfusion. For a number of medical disorders, transfusions are performed to replenish lost blood components. The blood's components, such as red blood cells, white blood cells, plasma, clotting factors, and platelets, are now frequently used in transfusions instead of the whole blood that was used in earlier times.

Hemoglobin is a component of red blood cells (RBC), which carry oxygen to the body's cells. Although they are not frequently utilized in transfusions, white blood cells are an essential component of the immune system and help the body fight illnesses. The "yellowish" liquid component of blood called plasma serves as a lubricant and is made up of essential nutrients and proteins for the body's overall health.

katrin [286]

Answer:

Explanation:

Left shift or blood shift is an increase in the number of immature cell types among the blood cells in a sample of blood.

For all of the above, you can say that blood shift (BS) happens (blood moves from non-vital organs to vital organs) when PV happens, but quite common Freedivers are using the term BS when describing the movement of the blood to the chest cavity to protect it from increasing pressure while diving deep.
