Answer:
1 . Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's metabolic activities.
2. During photosynthesis, plants trap light energy with their leaves. Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Glucose is used by plants for energy and to make other substances like cellulose and starch. Cellulose is used in building cell walls.
3.Photosynthesis in plants converts solar energy into chemical energy using electrons and protons from water. The process of photosynthesis in plants involves a series of steps and reactions that use solar energy, water, and carbon dioxide to produce organic compounds and oxygen.
4 . Chemical energy is stored in the bonds that connect atoms with other atoms and molecules with other molecules. Because chemical energy is stored, it is a form of potential energy. When a chemical reaction takes place, the stored chemical energy is released.

Which unit conversion allows you to convert 21.0 gallons into milliliters?
Some English and English-metric unit relationships: 1 liter = 1.057 quarts, 1 gallon = 4 quarts
Answer:
Explanation:
we are given
there are in 0.073 gallons
we can see that there are two non-zero places after decimals
so, there are two siginificant figures
step-1: Change gallons to quarts
we know that
1 gallon = 4 quarts
so, we can write as
step-2: Change into liter
we know that
1 liter = 1.057 quarts
or
step-3: Change into millilitre
we know that
Since, it is asking for only two significant figures
so, we can also write as

the air pressure from the atmosphere measures 0.5atm at an altitude of 18,000 ft. How much pressure is this in pounds per square inch?
Answer:
7.5 pounds per square-inch
At sea level, one square-inch of any surface has about 15 pounds of air sitting on top of it. At 18,000 feet, that same square inch has only 7.5 pounds per square-inch (psi) exerted on it.
The air pressure from the atmosphere measures 0.5atm at an altitude of 18,000 ft. than the pressure will be 7.5 pounds per square-inch.
What is the calculation at sea level?At sea level, one square-inch of any surface has about 15 pounds of air sitting on top of it. At 18,000 feet, that same square inch has only 7.5 pounds per square-inch (psi) exerted on it.
As the altitude increases, the atmospheric pressure increases. It's actually the opposite: from the graph, we see that as the altitude increases (going towards right on the graph), the pressure decreases.
The atmospheric pressure is 14 pounds per square inch at sea level.If we take altitude=0, we see that the value of the pressure is 14 pounds per square inch. As the altitude approaches sea level, the atmospheric pressure increases.
As the altitude approaches sea level we see that the value of the pressure increases. The atmospheric pressure gets close to 14 pounds per square foot as the altitude continues to increase.The pressure is 14 pounds per square inch only when the altitude is 0 miles above sea level.
Therefore, The air pressure from the atmosphere measures 0.5atm at an altitude of 18,000 ft. than the pressure will be 7.5 pounds per square-inch.

Scientists believe that the modern horse developed from a short, horse-like mammal about the size of a dog. Over millions of years, the horse increased in size and developed much longer legs. Horses with longer legs had a better chance of surviving than the shorter-legged members of the herd. How did longer legs help horses survive?
A. They allowed the horses to reach nuts in trees.
B. They allowed the horses to outrun predators.
C. They allowed the horses to carry more body weight.
D. They allowed the horses to capture prey.
Answer:
B
Explanation:
Horses with longer legs could out run predators and survive. Not getting eaten or injured helps with staying alive long enough to reproduce.

A process that converts sugars into cellular energy, ethanol, and carbon dioxide
The breakdown of food to create energy in the presence of oxygen
Answer:
Aerobic respiration is metabolic process in which food ( glucose) is metabolized ( in presence of oxygen) to derive large amount of energy ( in the form of ATP) through a series of three stages that is glycolysis, kreb cycle, and electron transport chain.
Anaerobic respiration another from of cellular respiration where food is broken down to derive energy in the absence of oxygen.
Alcoholic fermentation is a metabolic process by which sugar is converted into cellular energy ( in the form of ATP), ethanol, and carbon dioxide.

Complete the sentences to identify the difference between a nonmetal atom and its anion.
In an anion, there are more *blank* than *blank*, giving the anion a *blank* charge.
In nonmetal atoms, the number of *blank* and *blank* are the same and there is a *blank* charge.
key bank:
- a positive
- no net
- electrons
- protons
- a negative
- neutrons
Answer:
more protons than neutrons and the number of electrons and blank are blank
Explanation:
The complete sentences that distinguish the difference between a nonmetal atom and its anion are as follows:
In an anion, there are more electrons than protons, giving the anion a negative charge. In nonmetal atoms, the number of protons and neutrons are the same and there is a negative charge. What are Non-metals?Non-metals may be defined as the type of chemical element that lacks the characteristics of a metal. They do not show any metallic attributes. But in the periodic table, they range from colorless gases to shiny and high melting point solids.
In the whole periodic table, elements are classified into three parts. They are metals, non-metals, and metalloids. Each classification has its own attributes and characteristic properties.
The non-metals significantly gain electrons due to their stronger nuclear charge and become negatively charged anions.
Therefore, the complete sentences that distinguish the difference between a nonmetal atom and its anion are appropriately described.

O
C. The rate of the reaction begins to decrease as reactants are used
up
O
D. The rate of the reaction stays constant until the reactants are
gone.
The rate of the reaction depicts the speed at which the reaction occurs to produce the products. As the reactants get used up the reaction rate starts decreasing. Thus, option C is correct.
What are the factors affecting reaction rate?
The reaction rate of the chemical reaction gets affected by numerous factors that include temperature, the concentration of the reactants, catalyst, surface area, and physical state of the reactant.
The concentration of the reactant has a direct effect on the reaction rate as they are the deciding factor of the product formation. At the beginning of the reaction, the speed is fast compared to the end.
As the reactants start getting used up the reaction rate slows down as the molecules are not able to collide faster with other molecules to form the product.
Therefore, in option C. the reaction rate decreases with a decrease in concentration.

particular direction.

Low
Check ansive
Answer:The statement that best describes the motion of dye molecule in water is directed from a region of high to low concentration. The motion of the particles of the dye in water is described as diffusion: diffusion is the movement of molecules of a substance from one position to another.
Explanation:
Option A is correct. The statement that best describes the motion of the dye molecules in the water is "the dye molecules move in a directed way from high to low".
The motion of dye molecules in water is known to be random. Another name for random motion is Brownian motion and since diffusion is also Brownian motion, hence we can term the motion of the dye molecules in the water as "diffusion".
The water is held together by intermolecular forces and these forces are the ones that attract the molecules of the die carrying them away and making the process of molecular transport of the dye to be accelerated (moving from a region of high concentration to low concentration).
In conclusion, the statement best describes the motion of the dye molecules in the water is "the dye molecules move in a directed way from high to low".

Oxygen has 8 positively-charged protons. What is the number of negatively-charged electrons in an atom of Oxygen?
Answer:
Answer 9: Oxygen is atomic number 8 on the periodic table, which means it has 8 protons!
