Answer:

a theory cannot become a law

Explanation:

the difference between a scientific theory and a scientific law because a theory is an in depth explanation of an observed phenomenon. a law is a statement about an observed phenomenon or an unifying concept (i.e.: newtons law or gravity - no explanation on how it works or what it is just that it exists.)

Chen draws a diagram to show water changing from a liquid to water vapor. Complete the sentences. _______All the water molecules
romanna [79]

kinetic energy is needed by the molecules in order to escape from the surface.

All the water molecules in the liquid are moving randomly due to the presence of some energy in it. Some of the molecules have more kinetic energy due to absorption of heat energy from the surrounding environment.

Due to high kinetic energy, these molecules move enough to escape the surface of the liquid. This is called boiling point. This makes the liquid become gas so we can conclude that kinetic energy is needed by the molecules in order to escape from the surface.

lesantik [10]

Cell respiration involves different steps, among which there is the oxidative phosphorilation that produces and stores ATP. The answer is the <u><em>electron transporter chain</em></u>.

<h3>ELECTRON TRANSPORTER CHAIN -oxidative phosphorylation-</h3>

The electron transporter chain + chemiosmosis constitute the process of oxidative phosphorylation.

  • Chemiosmosis

Chemiosmosis refers to ATP production through a proton gradient.

  • Electron transporter chain

The electron transporter chain is a series of molecules and proteins located in the internal mitochondrial membrane.

It constitutes a series of enzymatic reactions to release and save energy for the correct functioning of the organism.

Along the chain, there are four proteinic complexes in the membrane, I, II, III, and IV, that contain the electrons transporters and the enzymes necessary to catalyze the electrons' transference from one complex to the other.

Different redox reactions occur to pass electrons along the chain.

Released energy creates a proton concentration gradient used to synthesize ATP.

<h3>Steps in the electectron transporter chain</h3>

1) NADH provides electrons to the first complex, Complex I. From there, electrons go to the coenzyme Q that carries them to complex II. Meanwhile, complex I pomp four protons to the intermembrane space.

2) Complex II receives electrons from CoQ and also receives electrons from FADH2. Electrons are sent from complex II to ubiquinone Q, which carries these electrons to complex III.

3) Complex III receives electrons from ubiquinone Q and pomps protons to the intermembrane space. Electrons are transferred to Cytochrome c.

Electrons travel from cytochrome c to complex IV.

4) Complex IV is the last complex that pomps protons to the intermembrane space.

5) Electrons are sent to O₂ molecules, which also receive protons in the matrix to create water molecules. Four electrons are needed to produce two water molecules from one O₂ molecule.

The proton gradient is used to produce ATP molecules.

In conclusion, <em>the set of proteins in the cristae of the mitochondrion, which collectively extract the energy from reduced coenzymes to form atp, are called the</em> <u><em>electron transporter chain</em></u>.

tensa zangetsu [6.8K]

Answer: The structure of the spinal cord can be described as consisting of all the above named.

Explanation:The spinal cord is the main pathway for information connecting the brain and peripheral nervous system. Much shorter than its protecting spinal column, the human spinal cord originates in the brainstem, passes through the foramen magnum, and continues through to the conus medullaris near the second lumbar vertebra before terminating in a fibrous extension known as the filum terminale.

It is about 45 cm (18 in) long in men and around 43 cm (17 in) in women, ovoid-shaped, and is enlarged in the cervical and lumbar regions.
