So the +3 part is where you start. so put a point on (0,3) because the +3 tells you to do that. then you have to remember rise over run. since it is a negative you will be going down. so go down 5 and then right 2 and put a point on where you landed at. then draw the line through to two points.
Answer: Spleen
Explanation:
The Spleen is an organ situated above the stomach and carry out important functions for body defence. This functions include:
- destruction of old red blood cells
- elimination of wastes such as dead platelets from the bloodstream
- storage of newly formed platelets.
Answer:
Once the oxygen diffuses across the alveoli, it enters the bloodstream and is transported to the tissues where it is unloaded, and carbon dioxide diffuses out of the blood and into the alveoli to be expelled from the body. Although gas exchange is a continuous process, the oxygen and carbon dioxide are transported by different mechanisms.
Transport of Oxygen in the Blood
Although oxygen dissolves in blood, only a small amount of oxygen is transported this way. Only 1.5 percent of oxygen in the blood is dissolved directly into the blood itself. Most oxygen—98.5 percent—is bound to a protein called hemoglobin and carried to the tissues.
Hemoglobin
Hemoglobin, or Hb, is a protein molecule found in red blood cells (erythrocytes) made of four subunits: two alpha subunits and two beta subunits (Figure 20.19). Each subunit surrounds a central heme group that contains iron and binds one oxygen molecule, allowing each hemoglobin molecule to bind four oxygen molecules. Molecules with more oxygen bound to the heme groups are brighter red. As a result, oxygenated arterial blood where the Hb is carrying four oxygen molecules is bright red, while venous blood that is deoxygenated is darker red.
It would have 64 protons. The atomic number is just how many protons an element has.
<span>The answer is Viking 1 and 2 that explored Mars
planet. Both were launched in 1975 and their mission ended in 1980. The main
objectives of the orbiters and landers were to take pictures of the planet,
collect samples, and conduct experiments to find signs of life on the planet. </span>
