Which list BEST identifies how the arrows should be arranged around the paper leaf in the model to represent the movement of matter and flow of energy during photosynthesis? A. Point into Leaf: sugars, oxygen (02), Point away from leaf: carbon dioxide(CO2), water(H2O) B. Point into Leaf: sugars, sunlight, Point away from leaf: carbon dioxide(CO2), oxygen (02), water(H2O) C. Point into Leaf: water(H2O), sunlight, Point away from leaf: carbon dioxide(CO2), sugars, oxygen (02) D. Point into Leaf: water(H2O), carbon dioxide(CO2) sunlight, Point away from leaf: sugars, oxygen (02
Answer:
D. Point into Leaf: water(H₂O), carbon dioxide (CO₂) sunlight, Point away from leaf: Sugars, oxygen (O₂)
Explanation:
Photosynthesis is the process used in the production of chemical energy in the form of energy containing organic compounds and oxygen from atmospheric carbon dioxide and liquid water enabled with the energy captured from light (mainly Sunlight) by the chlorophyll in green plants and other organisms
The basic chemical reaction involved in a photosynthesis reaction is presented as follows;

show using dots to illustrate high population density and low population density in the boxes provided in answer to guide questions
Answer:
Just add a plenty of dots in the first one and very few dots in the second one
An area with high population density will have many dots while areas will low population density will have few dots when using dots to illustrate population density.
What is population density?Population density is the ratio of the total number of organisms found in a given area to the total of the area of that place or habitat.
Population density = total number of organisms/total areaAn area with high population density indicates that more organised ate found per unit area than an area with low population density.
Therefore, using dots to illustrate population density, an area with high population density will have plenty dots while areas will low population density will have few dots scattered over.

Which of these is true about a pH meter?
It is inexpensive to use.
It measures pH indirectly.
It does not require calibration.
It can be used in any acid-base titration.
Answer:
That is, a pH meter is useful in detecting or knowing the acidity (due to ions) or alkalinity (due to ions) of a solution. Thus, we can conclude that out of the given options it is true about a pH meter that it can be used in any acid-base titration
Answer: D. It can be used in any acid-base titration.
Explanation:
Which substance would you expect to dissolve most rapidly in 100 mL water?
A
0.4 g granulated sugar
B
0.2 g powdered sugar
C
0.4 g powdered sugar
D
0.2 g sugar cube
Answer:
b because it is just 0.2 g and powdered sugar has more contact surface than granulated sugar or sugar cube
The solubility can be given as the amount of solute that can be dissolved in the 100 ml of the solution. The most rapidly dissolved sugar in water is 0.2 gram powdered sugar.
What is a contact surface?The contact surface can be given as the area of the compound that is in direct contact with the solution.
The solubility of the compound is found more in the solute with increased surface area.
The surface area of powdered sugar will be maximum, as more granules of the sugar will be in contact with the water than the cube or the granulated sugar.
Thus, the most rapid dissolution in water is found with 0.2 grams of powdered sugar. Thus, option B is correct.

Si se hace reaccionar CH3CH3 (etano) con cloro, en presencia de luz ultravioleta, los productos obtenidos en este paso son
Answer:
La reacción de etano, CH₃CH₃ y cloro, Cl₂ en presencia de luz solar se conoce como reacción de halogenación.
Los radicales de cloro se forman cuando el cloro se expone a la luz solar a continuación;
Cl₂ → 2Cl *
Se forma un radical etano cuando el etano, C₂H₆ reacciona con un radical libre de cloro, Cl *, como sigue;
C₂H₆ + Cl → C₂H₅ * + HCl
Se forma un producto halogenado cuando un radical libre de etano reacciona con una molécula de cloro como sigue;
C₂H₅ * + Cl₂ → C₂H₅Cl + Cl *
Un producto halogenado puede reaccionar además con un radical libre para producir como sigue;
C₂H₅Cl + Cl * → C₂H₅Cl₂
