Answer:
The light reactions provide the Calvin cycle with oxygen for carbon fixation, and the Calvin cycle provides the light reactions with sugars to produce ATP. The light reactions provide ATP and NADPH to the carbon fixation step of the Calvin cycle, and the Calvin cycle provides water and electrons to the light reactions.
Explanation:
The energy that drives the Calvin cycle comes from ATP and NADPH produced by the light reactions, that is, the energy capture reactions in the first stage of photosynthesis.
The Calvin cycle is a process that results from photosynthesis made by plants, through which Carbon dioxide is absorbed and transformed into organic material or biomass.
In the light phase, light energy is stored in organic molecules that provide energy to carry out the process (ATP) and have the ability to donate electrons (reducing power) to another molecule such as NADPH.These molecules formed in the light reactions participate in the reactions that make up this cycle during which carbon dioxide (CO2) taken from the atmosphere is fixed, incorporating it into the body in the form of glucose thanks to the action of the enzyme RuBisCo.Therefore, we can conclude that the molecules constituted in the light reactions (ATP and NADPH) participate in the reduction of carbon dioxide (CO2) through the series of reactions of the Calvin Cycle.

Answer:
Answer is the third one
Explanation:
All living organisms are made up of one or more cells, which are considered the fundamental units of life. Even unicellular organisms are complex! Inside each cell, atoms make up molecules, which make up cell organelles and structures.
Use your knowledge of valence electrons and how they affect bonds to figure out how carbon (Group 14) and oxygen (Group 16)
would be attached to one another. In carbon dioxide (CO2), how is the compound structured? (Use "-" to represent a single
bond and "=" to represent a double bond) (1 point)
C-O-O
O=C-O
C=O-O
O=C=O
Answer: D
Explanation:
O=C=O
Carbon is in group 14 having four valence electrons and oxygen is in group 16 having six valence electrons hence the correct structure of CO2 is O=C=O.
Carbon and oxygen are nonmetals. Nonmetals form compounds by sharing electrons in a covalent bond.Carbon, a group 14 element has four valence electrons while oxygen, a group 16 element has six valence electrons.
Carbon can share four valence electrons with two oxygen atoms in CO2 to form the structure O=C=O. In this way, all the atoms now obey the octet rule.

if one mole of na3po4·3h2o is heated extensively, how many moles of water are released?
When one mole of Na3PO4.3H2O is heated extensively, three moles of water are released.
The water molecules in Na3PO4.3H2O are called molecules of water of crystallization. These molecules are not covalently bonded to the Na3PO4 molecule. They are only loosely attached to the substance.
Strong heating will drive away these molecules of water of crystallization to give three moles of water in the product.
Hence, when one mole of Na3PO4.3H2O is heated extensively, three moles of water are released.

Answer:
I think that it would be better to have smaller cells because smaller cells takes less energy to transport waste and generally more efficient to control than larger cells. It is better to have smaller cells because larger and fewer cells takes up more nutrients, but doesn't cover as many surface area. In the end, smaller cells are more efficient, cover more surface area, and moves faster than bigger cells.

An electrolytic cell is a cell with a spontaneous redox reaction (option B).
What is an electrolytic cell?Electrolytic cell is an electrochemical cell that utilizes an external source of electrical energy to force a chemical reaction that would otherwise not occur.
An electrolytic cell converts electrical energy into chemical energy. The redox reaction in the cell occurs spontaneously and is responsible for the production of electrical energy.
Therefore, according to this question, option B is correct.

Answer:
relative proportions of the elements in a chemical reaction
A molecule or a compound can easily be represented by their formula.Subscripts in chemical formulas are used to indicate the relative proportions of the elements in a compound.
What is chemical formula?A chemical formula represent the identity and number of elements in a molecule or compound. Each element in periodic table has their own symbols. For example, hydrogen is H, oxygen having O, N for nitrogen, Na for sodium etc.
These chemical symbols are came from the first one or two letters of the Latin names of the elements. The number of these elements in a compound is given as subscripts of their symbols.
For example, there are two hydrogens and one oxygen in water and the formula is H₂O. Similarly the formula of carbon dioxide is CO₂ where one carbon and two oxygens are present. In this way the compounds can be easily identified and distuinguished using their chemical formulas.
