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:

The oxygen dissociation curve represents the percentage saturation of Hb with oxygen at different partial pressure of oxygen. The different partial pressures gives sigmoid shapes to the curve. When this curves shifts to right, it  indicates  low affinity or binding of oxygen by the Hb. it also indicates the unloading or releases of Oxygen by Hb molecules at condition of low pressure. e,g in the muscles during strenuous exercise.However, when the curve shifts to the left, this indicate high affinity for oxygen, great binding, at high partial pressure of oxygen.e,g in the lungs to take oxygen and releases CO2.

Therefore in this scenario, the statement -. <u>During strenuous exercise, the oxygen-hemoglobin dissociation curve shifts to the right.</u> is correct. because oxygen is needed by the muscles therefore ,oxygen should be less binded by Hb,  decrease affinity and easily unloaded to muscles.

<u>The statement </u>This rightward shift reflects an increase in the affinity of hemoglobin for oxygen and favors loading of O2 into hemoglobin in the lungs is wrong.

As explained above the rightwards shift indicated low affinity of Hb for oxygen(unloading)and  favours unloading at the muscles because during strenuous exercise the partial pressure of oxygen is very low(but that of CO2 high) in the muscles which favours low oxygen molecules  binding by Hb, and easy release to respiring cells.

Cervix

Janine recently had surgery on the neck, or narrow lower portion, of her uterus. Janine's surgery was performed on the cervix.  

The cervix is the narrow neck-like passage that forms the lower portion of the uterus in the human female reproductive system. The cervix joins the vagina and uterus and it is mainly made up of fibromuscular tissue. The two major parts of the cervix are ectocervix and endocervix. During menstrual cycle, the cervix opens a bit to allow the passage of menstrual flow. The cervix also dilates largely to allow the passage of baby during childbirth.
