Answer:
The answer is d. pyruvate
Explanation:
An oxidizing agent is the substance that gains electrons in a chemical reaction. At the end of the reaction it is reduced and its oxidation state increased.
A reducing agent is the substance that loses electrons in a chemical reaction. At the end of the reaction it is oxidized and its oxidation state decreased.
Pyruvate gains one electron, it is reduced from pyruvate to lactate; thus, pyruvate is the oxidizing agent.
NADH loses one electron, it is oxidized from NADH to NAD; thus, NADH is the reducing agent
Answer:
No
Explanation:
Only what state it is in, soild, liquid or gas. Particals never change duering this.
Answer:
- The wind is caused by differences in air pressure.
- An anemometer is a tool for measuring wind speed.
- The wind-chill factor has a cooling effect
Explanation:
Winds move from areas of high pressure to areas of low pressure. This is because the areas of low pressure are composed of hotter and less dense air. The cooler air from the higher pressure region rushes in to displaces the rising warm less dense air. The direction from which the winds prevail FROM is used to name the winds(such as westerlies blow from West to East). A wind vane, windsock and anemometer measure the direction and speed of wind. As wind passes over the skin, it causes a cooling effect (the wind chill factor) because it blows the sweat away from the skin carrying with it the heat.
