Which of the following is made up of 90% water, and 10% dissolved materials like nutrients, minerals, vitamins, digested food, and salts? *
red blood cells
white blood cells
plasma
O platelets

Plasma

Explanation:

The blood is a key part of the circulatory system. It is a tissue composed of cells that make it up. The blood contains the following components namely; plasma, red blood cells/erythrocytes, white blood cells/leukocytes, and platelets/thrombocytes.

The plasma is referred to as the "liquid" part of the blood and makes up the major part of the blood tissue. The plasma contains 90% water, and 10% dissolved materials like nutrients, minerals, vitamins, digested food, and salts. Hence, based on this question, the answer is PLASMA.

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.

i know can you plzz me with this question im sorry i didt answer your question i just need hel.
