I would be very grateful is you can help me!

Three constitutional limitations to the right to freedom of expression?

mr_godi [17]

Answer:

(1)limitation must be within the constitutional power of government; (2) the limitation must further an important or substantial governmental interest; (3) the governmental interest must be unrelated to the suppression of the freedom of expression; and

For a neuron to function, an input of free energy from ATP is required to set up the sodium and potassium ion concentration grad

Vlad [161]

Answer:

The lack of ATP would slow nerve responses to generate an action potential

Explanation:

Adenosine triphosphate (ATP) is the main source of energy in the cells. Moreover, ATPases are pumps that use ATP in order to transport sodium and potassium ions across the cell membrane and thus create an action potential. In stressful situations (e.g., escape from a predator) the lack of ATP would not allow to develop fast nerve responses, thereby ATP is required during rest periods and the flow of ions is used when is required a fast response.

There is an error in the above model.

ollegr [7]

ATP hydrolysis is the lysis of the molecule mediated by water. It releases a phosphate group and energy. It is a reversible reaction. (a) Reversible ATP hydrolysis. (b) added energy on the left and released energy on the right.

------------------------

ATP is a significant molecule involved in many of the cellular metabolic routes. These metabolic processes can either form it or break it.

ATP provides energy to many different functions in the organism.

ATP means adenosine tri-phosphate. It is composed of adenosine (an adenine plus a ribose), and three phosphate groups.

Note: you can also find adenosine Diphosphate (two phosphates) and adenosine monophosphate (one phosphate).

Oxygens from the phosphate groups only have a single bond to phosphate (there are no hydrogen bonds).

These single bonds, known as phophoanhydrid bonds, have a negative charge and tend to repel each other, making the molecule unstable.

So phosphate groups repel each other, and a considerable amount of energy is applied to keep them united. So phophoanhydrid bonds are high energetic bonds.

The forces that keep the phosphate groups together accumulate potential energy.

If these bonds are broken, part of this potential energy would be released.

When talking about breaking the molecule, we are referring to ATP hydrolysis. And the released energy is used in different cellular processes that require energy.

ATP Hydrolysis is the molecule lysis mediated by a water molecule.

ATP + H₂O ⇄ ADP + Pi + Energy

Pi is the released inorganic phosphate group.

This is a reversible reaction, meaning that the ADP can go back to ATP.

ADP + Pi + Energy ⇄ ATP + H₂O

(a) What is this a model of?

This model represents the reversible ATP hydrolysis.

In the superior part of the image, we can see an ATP molecule composed of adenine, ribose, and three phosphate groups. The yellow star behind represents the accumulated energy.

When ATP hydrolysis, it loses a phosphate group and part of the energy that was keeping this group in the molecule.

An ADP is composed after hydrolysis. We can see this molecule in the inferior area of the image.

ADP molecule is composed of adenine, ribose, and two phosphate groups.

Because hydrolysis is a reversible process, by adding a new phosphate inorganic group and energy, we can get a new ATP.

(b) Explain how you would change the model to make it correct?

What is wrong with this model is that instead of showing released energy during the hydrolysis process, it shows energy added to the reaction.

In the same way, instead of showing added energy to the reversible reaction, it shows released energy.

Added energy and released energy must be changed.

Added energy should be on the left
Released energy should be on the right

Individuals belonging to the subculture known for love of motorbikes and leather. Rival of the group known as mod

Nadusha1986 [10]

The subculture with an affinity for motorbikes and leather is known as Rockers. The rival group, those that prefer fashion and music, is known as Mod. These subcultures are of British origin and are divided on the basis of their tastes.

Rockers are also referred to as Leather Boys, given how much they enjoy wearing and using leather items.

When it was announced that the offshore areas would be opened up, the government also said that extensive studies would need to

Sunny_sXe [5.5K]

Answer:

Explanation:

Feasibilities studies-it analyzes a project to see if its possible technically, legally and financially.

Technical feasibility tells about if all the tools and equipment are available for the construction while financial talks of the financial ability.

Survey- They area of land where the offshore will be constructed will be surveyed and other surrounding environment to know the existing feature in such area of land that can pose threat to the offshore being constructed. This includes lives and houses built around the off shore to know how save their live is when the off shore built in such place.
