Assume you have a u-tube with a semipermeable capillary membrane made of simple squamous epithelium separating the solutions on either side. blood will be on the left side of the tube, and watery extracellular fluid (ecf) will be on the right side of the tube. predict what will occur to the water levels by hydrostatic pressure, the pressure of watery fluid pushing on a boundary.

The net movement of water would be a little bit to the left.

The ECF composition compared to blood composition is quite similar. Blood is composed of plasma ( watery extracellular fluid)  + cells + platelets. Due to the composition of blood compared to the ECF, blood would be a hypertonic solution. Whenever there is a semipermeable membrane, water will tend to move to the hypertonic side by osmosis.

many phylogenetic trees have a single lineage at the base representing a common ancestor. a lineage that evolved early from the root and remains unbranched is called basal taxon. when two lineages stem from the same branch point, they are called sister taxa.

can i get the brainliest pls

explanation:

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.
