Green plants produce their own food during photosynthesis. which of these statements about photosynthesis is true? a. water is one product of photosynthesis. b. oxygen is one product of photosynthesis. c. chlorophy11 is one product of photosynthesis d. carbon dioxide is one product of photosynthesis

B.

Explanation:

Water is one of the  reactants in photosynthesis. It is split into electrons, oxygen, and Hydrogen ions in first reaction of photosynthesis called photolysis of water. Therefore water is not a product.

Carbondioxide is another reactant  of photosynthesis that is reduced in the light independent stage of photsynthesis by H+ from photolysis to give Glucose.This reduction takes place in the Calvin cycle, in the presence of enzyme rubisco and substrate ribulose bisphosphate, The product is 2 molecules of 3C-glycerate phosphate, which later oxidized with hydrolysis of ATP, to form 2-Triose phosphate. The latter is converted to  glucose, Amino Acids, or fatty acids.

The Pigments for trapping energy in sunlight in the leaf chloroplast is called chlorophyll.It contains photosystems I and II. It is excited with the impact  of sunlight absorbed by the photo systems  I and II, and the electron is pick up by electron acceptors.  The electron is transferred  in cascade of reactions  which ends with  the  primary pigments of photosystem I absorbing electron from photosystem II. The primary pigment replaced the lost electron with electron from photolysis of water above.

Oxygen is the by-product of photosyntheis, it is produced when water is split in Photolysis of water.Oxygen is a by-product because it is not needed in subsequent stages of photosynthesis to  give the end products.it is given off  for cellular respiration in mammals.Therefore this is the correct answer.

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.

explanation:

hypoxemia refers to a below usual concentration of oxygen in the blood, mainly in the arteries. hypoxemia is an indication of an issue associated with circulation or breathing and may lead to various symptoms like shortness of breath.  

the condition is identified by determining the level of oxygen in the blood sample obtained from an artery. it can also be predicted by determining the oxygen saturation of the blood with the application of a pulse oximeter.  

the normal arterial oxygen is about 75 to 100 mm hg. the values underneath 60 mm hg is generally considered with the requirement for supplemental oxygen. the normal pulse oximeter readings generally range between 95 to 100 percent. the values under 90 percent are regarded as low.  

in the given case, the oxygen saturation is measured at 93 percent, hence, there is no need to administer oxygen, that is, one should withhold oxygen.
