Answer:
Find the area of a square or rectangle by multiplying the length times the width. This formula looks like l*w. If the length is 5 and the width is 2, the area is 10 square units.

Sickle cell anemia is a genetic condition that distorts the shape of the hemoglobin. This reduces the capacity of the red blood cells to carry oxygen. Another effect is that the distorted red blood cells come together forming a heavy and compact collection of cells that can block the flow of blood. The sedimentation rate is increased by sickle cell anemia.

Answer:
a solution of each sodium salt at the same concentration
Explanation:
If a scientist wishes to study the electrical potential that develops between ice  and the sodium salts solution of the ions (F-, Cl-, Br-, or I-) in order to determine which ion produced the greatest electrical potential; he must compare the electrical potential that develops between ice and a solution of each sodium salt at the same concentration.
This means that conclusions can not be reached unless the sodium salt of each ion at the same concentration is compared so as to ensure consistence in the results of the study.
