Answer:
Mitochondria
Explanation:
Glucose in an energy molecule contained in carbohydrate food substances. The end product of the digestion of carbohydrate is glucose which is broken down to produce energy.
The sequence of breakdown of glucose is as follows; In the first step, 6-carbon glucose is broken down into two molecules of 3-carbon pyruvic acid. This occurs in the cytoplasm of the cell. It is an anaerobic process.
In the second step which occurs in the mitochondrion, each of the molecules of pyruvic acid is now oxidized to carbon dioxide and water and energy is produced in the process.

Explanation:
Red is dominant to white for flower color in a particular plant. If a red flowered plant (RR) is crossed with a white flowered plant (rr), what color will the offspring be?
Answer:
The offspring will all have red-colored flowers
Explanation:
A dominant character is one that is always expressed when it is present.
A recessive character or trait is one that is only expressed in the absence of the dominant character. Thus, when the dominant and recessive character are both present in an organism, the recessive character will be hidden while the dominant character will be expressed.
According to Menedel's laws of inheritance, in the cross between the dominant (RR) red-flowered plant and the recessive (rr) white-flowered plant, the genotype of the offspring will be as follows:
RR x rr = Rr, Rr, Rr,Rr
The offspring are all heterozygous for flower color. However, since red flower color is dominant over white flower color, all the offspring produced will have red-colored flowers.
How many L of a 7.5 H2SO4 stock solution would you need to prepare a dilute solution 100 L of 0.25M H2SO4
Answer:
3.33 L
Explanation:
We can solve this problem by using the equation:
C₁V₁=C₂V₂Where the subscript 1 refers to one solution and subscript 2 to the another solution, meaning that in this case:
C₁ = 0.25 MV₁ = 100 LC₂ = 7.5 MV₂ = ?We input the data:
0.25 M * 100 L = 7.5 M * V₂V₂ = 3.33 LThus the answer is 3.33 liters.
You need 2 pieces of bread, 1 tablespoon of peanut butter and 2 tablespoons of jelly to make a
sandwich. If you have 10 pieces of bread, 4 tablespoons of peanut butter and 20 tablespoons of jelly,
what is the limiting reactant?
Answer:
peanut butter
Explanation:
because you have 10 pieces of bread, 4 tbs of peanut butter, and 20 tbs of jelly, meaning you can make 5 sandwwitches with the bread, 4 sandwitches with the peanut butter, and 10 sandwitches with the jelly. so you dont have enough peanut butter to make all the sandwitches
According to the given scenario, If one have 10 pieces of bread, 4 tablespoons of peanut butter, and 20 tablespoons of jelly, the limiting reactant will be peanut butter.
What is a limiting reactant?
The reactant that gets consumed first in a chemical reaction and result in limiting the formation of product is referred to as a limiting reactant.
According to the given scenario, the quantity of peanut butter will get consumed first so it will act as a limiting reactant.
Thus, If one have 10 pieces of bread, 4 tablespoons of peanut butter, and 20 tablespoons of jelly, the limiting reactant will be peanut butter.

Iron is extracted from its ore (hematite) in the blast furnace. Which gas is produced as a waste product?
Answer:
CO2
Explanation:
CO2 or carbon dioxide is produced when iron is extracted from its ore. Carbon monoxide Co is used as reducing agent in iron extraction. In this reaction iron ore is reduced to iron and CO is oxidized to CO2 or carbon dioxide which is released in the process. There extraction of iron is redox reaction.

2. How much heat is needed to convert 2.7 moles of ethanol at its boiling
point from liquid to vapor?
Answer:
así que busca, pero la respuesta está en por cierto Explanation:
The quantity of heat needed to convert 2.7 moles of ethanol at its boiling point from liquid to vapor is 104.49 kJ
From the question,
We are to calculate the heat needed to convert 2.7 moles of ethanol from liquid to vapor.
Using the formula
Q = n × ΔHvap
Where Q is the quantity of heat
n is the number of moles
and ΔHvap is the enthalpy of vaporization
From the given information,
n = 2.7 moles
and
ΔHvap of ethanol = 38.7 kJ/mol
Putting the parameters into the formula, we get
Q = 2.7 × 38.7
Q = 104.49 kJ
Hence, the quantity of heat needed to convert 2.7 moles of ethanol at its boiling point from liquid to vapor is 104.49 kJ

which substance is reduced ?
Cl^2 +2KBr= 2KCl + Br2
Answer:
Initially Br is in -1 oxidation state and Cl in 0 oxidation state. Finally Cl is in -1 o.s. and Br in 0.
This means that Br has oxidised from -1 to 0 and Cl is reduced from 0 to -1.
KBr is reducting agent as it helps Cl to reduce.
Cl2 is oxidising agent as it helps Br to oxidise.

The diagram shows the different models of the atom that eventually led to the modern atomic theory.
Which model was proposed as a result of Rutherford's scattering experiment where positive particles did not pass straight through a foil as expected? (5 points)
Model A
Model B
Model C
Model D
Answer:
B.
Explanation:
The atomic model represents the position of the sub-atomic particles. Model A was proposed after Rutherford's scattering experiment where the positive particles were deflected in the middle. Thus, option A is correct.
What was Rutherford's atomic model?Rutherford's atomic model proposed the presence of the positive nucleus in the middle of the atom while the electrons surrounded them in their orbitals with a negative charge.
He performed the scattering experiment where alpha particles emitted by the radioactive element were used to locate the positions of the electrons, neutrons, and protons.
According to the experiment, model A, best fits as the nucleus made of protons and neutrons takes the center of the atom with negative electrons surrounding them. The nucleus is small as compared to the entire atom.
Therefore, option A. model A best proposes Rutherford's model.

What is filteration:Filtration, the process in which solid particles in a liquid or gaseous fluid are removed by the use of a filter medium that permits the fluid to pass through but retains the solid particles. ... In some processes used in the production of chemicals, both the fluid filtrate and the solid filter cake are recovered.
When do we use it:Filtration is used to separate particles and fluid in a suspension, where the fluid can be a liquid, a gas or a supercritical fluid. Depending on the application, either one or both of the components may be isolated.
In order to separate a salt-water mixture,should a student use filtration:The mixture can be separated by filtration, by dissolving the mixture in water. Salt will dissolve in the water, whereas sand will not.

hope it help's. pls mark as the brainliest.Rocket out.Is there a solution for the impacts overfishing?
Answer:
The world’s oceans are so big we thought for a long time that there was nothing humans could do to hurt them. Now we’re facing an imminent and global collapse of our fisheries, projected to happen as early as 2048, thanks to overfishing, wasteful fishing practices and massive overconsumption. But, there are a few key tried-and-tested solutions to overfishing that have been successfully implemented around the world. The trick is to scale these solutions up to a global scale, encouraging countries that have originally been resistant to helping and get them onboard, and supporting countries that don’t have the means to update their fishing policies themselves.

(e) Another student investigated the rate of a different reaction
Table 3 shows the results from the different reaction
Headings that you a
will appear here.
Table 3
Mass lost when the reaction was
complete
9.85 g
Time taken to complete the reaction
2 minutes 30
seconds
Calculate the mean rate of the reaction using Table 3 and the equation:
mass lost in g
mean rate of reaction time taken in s
Give your answer to two decimal places.
Answer:
0.07 g/s.
Explanation:
From the question given above, the following data were obtained:
Mass lost = 9.85 g
Time taken = 2 min 30 s
Mean rate =?
Next, we shall convert 2 min 30 s to seconds (s). This can be obtained as follow:
1 min = 60 s
Thus,
2 min = 2 × 60 = 120 s
Therefore,
2 min 30 s = 120 s + 30 s = 150 s
Finally, we shall determine the mean rate of the reaction. This can be obtained as illustrated below:
Mass lost = 9.85 g
Time taken = 150 s
Mean rate =?
Mean rate = mass lost / time taken
Mean rate = 9.85 / 150
Mean rate = 0.07 g/s
Therefore, the mean rate of the reaction is 0.07 g/s
