How many distinct stages must occur between the point when light first encounters chlorophyll and the point at which
Novay_Z [31]

Explanation:

<u>Three.</u>

Photosynthesis produces glucose and O2 from inorganic CO2, light energy and water.  This occurs in distinct steps: 1) light fixation,  2) electron transport and NADPH production 3)  ATP generation, then 4) carbon fixation and carbohydrate production.

6CO2 + 6H20 + (energy) → C6H12O6 + 6O2

Further Explanation:

Photosynthesis is a chemical process, essential to plant and other primary producers producing energy. As oxygen is emitted, energy in the form of glucose molecules is created from light, water, and carbon dioxide. It happens in several complicated stages, photosynthesis is a speed-limited process, depending on several factors including concentration of carbon dioxide, ambient temperature and light intensity; energy is extracted from photons, i.e. light particles, and water is used as a reduction agent. It occurs in the thykaloids, where pigment molecules live like chlorophyll.

Photosynthesis occurs in several complex steps and is a reaction of a small duration, depending on several fa factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. Water supplies the chlorophyll in plant cell with replacement electrons for the ones removed from photosystem II.

Additionally,

  • Water (H2O) divided into H+ and OH-by light during photolysis serves as a source of oxygen along with acting as a reduction agent; it reduces the NADP molecule to NADPH by supplying H+ ions and generates molecules of the energy storage molecule ATP through an electron transport chain.
  • This happens in the thykaloids, where pigment molecules reside like chlorophyll.
  • Later, NADP and NADPH are used in dark reactions during the Calvin cycle, where monosaccharides or sugars such as glucose are produced after several molecules have been modified. These store energy in their bonds which in the mitochondria can be released in respiration.

As altitude increases, air pressure __________ (increases, decreases, or stays the same). This is a(n) ________(direct, indirect
lions [1.4K]

Answer:

The correct answer is - decreases. direct.

Explanation:

Altitude is a distance measurement of distance in a vertical manner or how high something from the sea level. It helps in the height of the mountains and different places.

Air pressure and altitude are the two factors that are in direct relation as the air pressure decreases with the increase in altitude. the gases present in the higher elevations are fewer than the sea level.

marin [14]

Answer:

a. He is missing a control group of mice that did not receive the new antibiotic.

Explanation:

In any experiment especially experiments testing effectiveness of a drug, there should be a control group.

The importance of a control group is to minimize the effects of other variables other than the independent variable hence increasing reliability of the results.

in this case, a group of mice that did not receive the new antibiotic would have served as the control group.

cupoosta [38]

Answer:

D two organisms depend on each other for survival.

Explanation:

Symbiotic relationship is a type of relationship between two organisms in which the both of them gain something positive from each other. A good example is the relationship between the cattle and egret. The egret helps in grooming the cattle and the cattle in return provides food for the egret.

In a symbiotic relationship, two organisms depend on each other for survival and is the right choice in the above question.
