This flower must have grown in neutral soil, with little aluminum.

In some varieties of bigleaf hydrangeas (Hydrangea macrophylla), soil pH determines whether the plant will produce blue or pink flowers. Blooms appear bluest when grown in acidic soil with a pH in the 5.0 to 5.5 range. The same cultivar may sport pink blossoms in soil with a more neutral pH, such as 6.5 to 7.0. Florists control flower color by potting soil mixture

Although blood is a fluid, nearly half its volume is composed of cells. The most numerous cells are ________. The remainder of t
lana66690 [7]

Answer:

The correct answer will be option-A

Explanation:

The centrifugation of the blood shows that 45% of the blood is composed of the cellular content and 55% blood plasma or liquid.

Erythrocytes or red blood cell constitute for about 41% of the total blood cells which transports the oxygen by binding it to the haemoglobin. The presence of haemoglobin is the reason the cell appears red which cause the color of the blood to appear red.

The remainder of the cell is white blood cells or leukocytes which play important role in providing the defence mechanism against the pathogen.

Thus, option-A is the correct answer.
