The oxygen that is released as o2 during photosynthesis came from _____________ molecules.
AlexFokin [52]

Answer:

Water (H2O)

Explanation:

Light reactions of photosynthesis release oxygen as a by-product. In the presence of sunlight, photolysis of water molecules occurs. Splitting of two water molecules obtains four electrons, four protons, and molecular oxygen. The oxygen-evolving complex, also called the water-splitting complex is associated with photosystem II (PS II). Splitting of water occurs in the oxygen evolving complex and the released electrons are passed one at a time to the reaction center of PS II. Therefore, a water molecule serves as a source of oxygen released during photosynthesis.

On earth, water can exist as a solid,a liquid,
Hitman42 [59]

On earth, water can exist as a solid,a liquid, or a gas because "the Earth is at an ideal temperature due to its distance from the Sun".

<u>Option: </u>A

<u>Explanation:</u>

Water can occur at a specific temperature of 273.16 K and pressure of 611.2 Pa in three various states i.e. solid, liquid and gas, and this phase is considered to be triple point water. At such a temperature and pressure the water keeps moving from solid to liquid phase and vice versa.

The average global temperature of Earth at aphelion is about 4 degrees Fahrenheit, or 2.3 degrees Celsius higher than at perihelion. This results as the the Southern Hemisphere has more oceans while the Northern Hemisphere has more land, which make the heating up of the land easier and faster.

4. Many of your body’s responses operate off of either negative or positive feedback loops. When you are cold, you shiver. Expla
GenaCL600 [577]

Answer:

The tendency to maintain a stable, relatively constant internal environment is called homeostasis. The body maintains homeostasis for many factors in addition to temperature. For instance, the concentration of various ions in your blood must be kept steady, along with pH and the concentration of glucose. If these values get too high or low, you can end up getting very sick.

Homeostasis is maintained at many levels, not just the level of the whole body as it is for temperature. For instance, the stomach maintains a pH that's different from that of surrounding organs, and each individual cell maintains ion concentrations different from those of the surrounding fluid. Maintaining homeostasis at each level is key to maintaining the body's overall function.

madam [21]

Answer:

The correct answer is "Decreased metabolic rate".

Explanation:

The sympathetic division is the part of the autonomic nervous system that deals with the coined "fight or flight" response when facing with a stressful situation. Is not true that when the sympathetic division is activated the metabolic rate decreases, actually, the effect is the opposite. The sympathetic division influences key processes such as glucose and lipid metabolism as well as daily energy expenditure, particularly, it influences the resting metabolic rate (RMR).
