Answer:
x-axis
Explanation:
you control those values/variables
On a cartesian plane, the independent variable belongs on the x-axis.
What are coordinates?A pair of numbers called coordinates are used to locate a point or a form in a two-dimensional plane. The x-coordinate and the y-coordinate are two numbers that define a point's location on a 2D plane.
The independent variable is the variable that is being manipulated or controlled in an experiment, and its values are typically plotted along the horizontal or x-axis.
The dependent variable, which is the variable being measured or observed in response to changes in the independent variable, is usually plotted on the vertical or y-axis.
This convention allows us to easily visualize and analyze the relationship between the two variables.
therefore, The independent variable belongs on the x-axis (horizontal line) of the graph and the dependent variable belongs on the y-axis (vertical line). The x and y axes cross at a point referred to as the origin, where the coordinates are (0,0).

What is the function of a chloroplast? A. Gamete production B. Cellular respiration C. Fermentation D. Photosynthesis
Answer:
So i had these notes from a couple of days ago and I’d like to help u out
Explanation:
Photosynthesis
Carbon dioxide enters through the leaf which contains small pours called stomata. The carbon dioxide then enters the cells of the leaf.
Inside the cell carbon dioxide diffuses into the chloroplasts. Where photosynthesis takes place
Chloroplasts use energy from sunlight to transform carbon dioxide and water into sugar and oxygen.
The light reactions
Inside chloroplasts there are these flat membranous sacs called thylakoids.
Thylakoids are the place were light energy is converted into chemical energy in the first phase of photosynthesis the light reactions.
Photosystems
Photosystems are large complexes of proteins and chlorophyll (capture light energy)
Electron transport chain
This chain connects the two photosystems.
Electron carrier
These shuttle (transport that is mainly between 2 things going back and forth) electrons from one photosystem to another
Photosystem
One of the photosystems are used to absorb energy which then excites the electrons that then enter the electron transport chain. These electrons are replaced with electrons stripped from water creating oxygen as a byproduct.
The electrons on the chain
The energised electrons are flowing down the electron transport chain releasing energy that is used to pump hydrogen ions
Hydrogen ions
An atom or molecule that has a net electrical charge due to the loss of one loss or one gained electron.
The electrons on the chain
As the hydrogen ions get pumped out they are then absorbed into the thylakoids
In the photosystem on the right light energy excites electrons and this time the electrons are captured by an electron carrier molecule also known as NADPH
The high concentration of hydrogen ions inside the thylakoid powers ATP synthase producing ATPS the light reactions in the thylakoid have produced two products, ATP and NADPH.
Those two products then power the production of sugar in the Calvin cycle
THE CALVIN CYCLE (C3 Cycle)
The Calvin cycle takes place outside the thylakoids in the stroma (the thick fluid of the chloroplast).
At the beginning of the cycle
carbon dioxide molecules combine with molecules called rubp the resulting molecules go through a series of reactions powered by ATP and NADPH from the light reactions sugar molecules known as g3ps are produced.
G3ps
Most of the g3ps molecules are rearranged back into rubp’s that begin the calving cycle again.
The important product
Then some of the left over g3ps is the remaining g3p sugar, some g3ps are used to build glucose which can then combine into starch or even cellulose
Bits of left over g3ps are also able to break down by cellular respiration, which uses oxygen in the plants own mitochondria, this generates ATPS that can power other work of the plant.
The left overs
Excess oxygen diffuses out of the leaf through the pores while more carbon dioxide goes into the leaf pores.

RNA differs from DNA in the type of a) purines & pyrimidness b) sugars & Purmes c) sugar & pyrimidness. dl pyrimidness (please give right answer only)
Answer:
There are two differences that distinguish DNA from RNA: (a) RNA contains the sugar ribose, while DNA contains the slightly different sugar deoxyribose (a type of ribose that lacks one oxygen atom), and (b) RNA has the nucleobase uracil while DNA contains thymine.
So, the answer is
Explanation:
Suppose you have a beaker of sugar and a beaker of salt. They are unlabeled and the white crystals look identical. Your assignment is to identify each one. Tasting would make identification easy, but you should never taste anything in a science lab. Instead, you can use scientific knowledge and investigation to help you identify each substance.

B. Both molecules contain covalent bonds.
C. NaCl contains a covalent bond, and C12H22O11 contains ionic bonds.
D. NaCl contains an ionic bond, and C12H22O11 contains covalent bonds.
As per the given scenario, NaCl contains an ionic bond, and [tex]C_1_2H_2_2O_1_1[/tex] contains covalent bonds. The correct option is D.
What is the difference between ionic and covalent bonding?An atom can primarily participate in two types of bonding: covalent and ionic. The sharing of electrons between two or more atoms is referred to as covalent bonding.
When two or more ions come together and are held together by charge differences, ionic bonds form.
Covalent bonds are formed when two nonmetals come together, whereas ionic bonds are formed when a metal and a nonmetal come together.
Molecules formed by covalent bonds have a lower melting point than those formed by ionic bonds. The boiling point has the same relationship.
Electrons are basically involved in the formation of both ionic and covalent bonds.
NaCl is possess ionic bonding between sodium and chlorine ions, while table sugar have covalent bond.
Thus, the correct option is D.

Explain how increasing the temperature increases the rate of the reaction
Explanation:
The more the temp rises the more energy it generates. In a reaction there are molecules in which they bounce around and collide in order to form the reaction. With more energy being introduced the molecules will speed up and collide more often than what the speed was before which directly relates to why the rate of a reaction is increasing.

plants can change the main product of photosynthesis into other substances. Name two of these substances and describe the function of each
Answer:
The products of photosynthesis are glucose and oxygen. Glucose is used by plants for energy and to make other substances like cellulose and starch. Oxygen is released as a byproduct/waste product. In cellular respiration, oxygen is used to break down glucose, releasing chemical energy and heat in the process.
Explanation:
Specifically, plants use energy from sunlight to react carbon dioxide and water to produce sugar (glucose) and oxygen. Many reactions occur, but the overall chemical reaction for photosynthesis is: Carbon Dioxide + Water + Light yields Glucose + Oxygen
