As blood passes through the capillary bed in an organ, the capillaries join to form venules (small veins). If the blood speed increases by a factor of 4.00 and the total cross-sectional area of the venules is 10 cm2, what is the total cross-sectional area of the capillaries feeding these venules? How many capillaries are involved if their average diameter is 1 x 10-5 m?

answer and explanation;

composition refers to both the types of minerals within a rock and the overall chemical makeup of the rock while texture refers to the size and arrangement of the minerals or grains that make up a rock. both composition and texture can be used to classify rocks, such as igneous rocks. texture describes how the rock became solid or crystallized from liquid, melted rock. composition of a rock describes the minerals that make up a particular rock.

Ibelieve the answer is either b or c, but i'm leaning more towards c.hope my answer has you : )
