The mitochondria are the labeled structure that breaks down food molecules to make ATP.
The information regarding the mitochondria is as follows:
- It is the membrane-bounded cell i.e. singular.
- It generated the chemical energy that is required to power the biochemical reactions of the cell.
- Also, the chemical energy should be generated via this that stored in the small molecule known as ATP.
Therefore we can conclude that the mitochondria are the labeled structure that breaks down food molecules to make ATP.

Explanation:
To answer this, it would be helpful to first determine what natural selection is. Natural selection is a biological process in which species evolve and adapt over time, in order to better fit their environment.
In any ecosystem, there are going to be limited resources. This simply means that species that are most suitable for the environment will survive and have the chance to reproduce.
This means that the environment determines when natural selection happens, but also what it looks like.
This might be better understood with an example:
For example, after several volcano eruptions in a stretch of the desert, the field mice population, over the next generations, gradually became black, rather than their original tan color.
This is because the vast desert sands were replaced with large patches of black volcano rock, so the mice that were previously able to camouflage and avoid detection by predators now weren't able to.
On the other hand, genetically mutated black field mice now had a far greater chance of surviving, and hence the population of field mice gradually became black.
This example illustrates how a change in the environment, caused the process of natural selection and ultimately the characteristic of having black fur to be more advantageous.
Over time, the process of natural selection made it so that the field mice population was black.

To find the volume of a 240-piece of cork, we need to know the mass or total weight of the cork. The given information only states the density of the cork, which is 0.24, but it does not provide the mass directly.
Density (ρ) is defined as the mass (m) of an object divided by its volume (V):
Density (ρ) = Mass (m) / Volume (V)
Given: Density (ρ) = 0.24 g/cm³ (as 0.24 is equivalent to 0.24 g/cm³ for this case)
Mass (m) = 240 g
We need to rearrange the formula to solve for the volume (V):
Volume (V) = Mass (m) / Density (ρ)
Volume (V) = 240 g / 0.24 g/cm³
Volume (V) = 1000 cm³
So, the volume of the 240 grams of cork is 1000 cubic centimeters (cm³).

You first need to convert the milligrams into grams so that the units for mass and density both have grams in them. 240mg equals .240g
you have to divide its mass by the density to get volume. (.240 g)/(0.24 g/ml)=1ml
I hope this helps.
Molar Mass of N2 = 28.02 g/mol
Molar Mass of H2 = 2.02 g/mol
Molar Mass of NH3 = 17.04 g/mol
Answers
Answer:
N₂
Explanation:
The limiting reactant is the one that gives the smaller amount of product.
Assemble all the data in one place, with molar masses above the formulas and masses below them.
M_r: 28.02 2.02 17.04
N₂ + 3H₂ ⟶ 2NH₃
m/g: 5.42 5.42
1. Calculate the moles of each reactant
2. Identify the limiting reactant
Calculate the moles of NH₃ we can obtain from each reactant.
From N₂:
The molar ratio of NH₃:N₂ is 2:1.
From H₂:
The molar ratio of NH₃:H₂ is 3:2.
N₂ is the limiting reactant, because it gives the smaller amount of NH₃.

Answer:
D. Physics
Explanation:
First, let's define all the answer choices.
Biology: Biology is the study of life and living things. Biology deals with the function, growth, origin and more of organisms.
Chemistry: Chemistry is the study of matter, elements, atoms, compounds, molecules and more. Chemistry is also concerned with chemical reactions.
Planetary science: Planetary science is basically the study of planets. This is the study of planets, moons and planetary systems.
Physics: Physics is the study of matter, energy, and their interactions. This helps us to explain and understand things that happen in the universe.
The best choice is D. Physics. Physics is the study of how matter and energy interact.
Final answer:
The D. Physics is the study of how matter and energy interact. It helps us understand how things work and why they behave the way they do.
Explanation:
Physics is a natural science that explores the fundamental principles governing the universe. It studies the behavior of matter, energy, space, and time through the formulation of physical laws and mathematical equations. Physics covers diverse topics, including mechanics, electromagnetism, thermodynamics, relativity, quantum mechanics, and astrophysics, explaining phenomena from the subatomic to cosmic scales.
Thus, it is the study of how matter and energy interact. It is concerned with describing the interactions of energy, matter, space, and time to uncover the fundamental mechanisms that underlie every phenomenon. In simple terms, physics helps us understand how things work and why they behave the way they do.
