Answer:The same amount of matter exists before and after the change—none is created or destroyed. This concept is called the Law of Conservation of Mass. In a physical change, a substance's physical properties may change, but its chemical makeup does not.
Explanation:
In the dark, an object is more clearly seen when viewed in peripheral vision than when viewed directly, this phenomenon occurs because the rods located in the retina are:<u> more </u><u>sensitive</u><u> in the dark than </u><u>cones</u>.
The retina extends through the posterior portion of the eyeball is the innermost layer and in it are the photoreceptors: cones and rods.
Rods and cones are the two types of photoreceptor cells in vertebrates that capture light energy (photons) and convert it into electrical signals.
- The rods are sensitive to changes in light, since their detection thresholds are low, so they only come into operation when the light intensity is low (scotopic vision or night vision).
- Scotopic vision has relatively low acuity, as the details of an object cannot be discerned or its color appreciated.
- On the contrary, cones have a much higher threshold for light, they are responsible for daytime vision (photopic vision) and their mission is to detect colors and shapes (details).
Therefore, we can conclude that in the dark, an object is more clearly seen when viewed in peripheral vision than when viewed directly, this phenomenon occurs because the rods located in the retina are: more sensitive in the dark.

Color: oxygen poor blood is dark red why? 1) Fact that we can see the blood traveling through the superficial veins through skin blood. 2) how light is reflected back to the eye from different colors.
Volume: In an adult 5L, men tend to have (5mL to 6mL) -sustaining normal blood volume is essential to maintaining blood pressure
Viscosity: 4 to 5 times more viscous than water. It changes if erythrocytes increase, and the amount of fluid decreases or both.
Plasma concentration: The relative concentration of solutes determines whether fluid move in and out of the plasma by osmosis as blood is transported through capillaries. ex. if an individual is dehydrated the plasma becomes hypertonic.
Temperature: 1 degree Celsius higher than body temapture.
Blood PH: Slightly alkaline, 7.35 and 7.45, dependent upon H+
