The answers are solution, colloid, and suspension respectively.
NaCl or salt is dissolved in the blood. So this makes blood and salts a solution. You won't be able to discern the NaCl in a solution of blood and NaCl.
Proteins in the plasma make blood a colloid. Protein particles are bigger than particles in a solution but are smaller than particles in a suspension.
Lastly, blood cells and blood make up a suspension. You would notice this characteristic in blood because red blood cells settle.
You can observe this when your blood is drawn. When it is placed in a test tube and left alone or placed in a centrifuge. The components separate into liquid on top, where you cannot see particles like salt; plasma in the middle, which has pale yellow color and also contains proteins; and the red blood cells at the bottom that settled.
Answer:
Origin and Insertion
Explanation:
The origin is the point of attachment of a muscle that remains relatively fixed during contraction.
The insertion is the point or mode of attachment of a skeletal muscle to the bone or other body part that it moves.
Answer:
the answer should be G
Explanation:You usually can't break rocks apart by wind.
Answer:
Endothermic reactions absorb energy, so the sum of the energy required exceeds the amount that is released. In all types of chemical reactions, bonds are broken and reassembled to form new products.
Explanation:
Hope this helps!
Chemical reactions make and break the chemical bonds between molecules, resulting in new materials as the products of the chemical reaction. ... Breaking chemical bonds absorb energy, while making new bonds releases energy, with the overall chemical reaction being endothermic or exothermic.
