Answer:

Social justice aims to give individuals and groups fair treatment and an impartial share of social, environmental and economic benefits. The concept promotes the fair distribution of advantages and disadvantages within a society, regardless of background and status.

Environmental justice deals explicitly with the distribution of environmental benefits and the burdens people experience, at home, at work, or where they learn, play and spend leisure time. Environmental benefits include attractive and extensive greenspace, clean air and water, and investment in pollution abatement and landscape improvements. Environmental burdens include risks and hazards from industrial, transport-generated and municipal pollution.

Whose main job is to break down sugar to release energy that a plant cell can use?

Tasya [4]

Answer:

The Mitochondria

Explanation:

Mitochondria are membrane-bound cell organelles that generate most of the energy required to power the cell's organic chemistry reactions. Energy created by the mitochondria is kept in a tiny molecule known as adenosine triphosphate (ATP).

write the overall rate law for the initial rate of the reaction as a fraction.

Rate=k(________/_________)

Answer:

The overall rate law for the initial reaction is = $k_{overall} [H_{2}SO_{4}]^{2} [C_{6}H_{6}]$

Explanation :

Frist of all, all the common terms are cancelled out and written the overall reaction.

As we know that the rate depednant step is the slowest step of the reaction, rate law is :

rate = $k_{2} [SO_{3}][C_{6}H_{6}]$

But the problem is that SO3 cannot be written in the overall rate law because it is an intermediate.

Rate law for synthesis of S03 is as follows :

rate = $k_{1}[H_{2}SO_{4}]^{2}$

Hence when we substitute equation 2 in equation one,

Rate comes out to be = $k_{overall} [H_{2}SO_{4}]^{2} [C_{6}H_{6}]$

Which of the following is true of the energy levels of electrons in shells?

anyanavicka [17]

Answer:

Option C is the correct. Valence electrons have a higher energy level than those in other filled shells

Explanation:

Electrons must lose energy to move from the first to the second shell. FALSE

The electrons always win energy to move from the first to the second shell.

All the electrons in an atom have similar energy levels FALSE.

They are not neccesary similar. In hydrogen these are the level energy -13.6 eV , -3.4 eV , -1.51 eV , -85 eV and -54 eV

Electrons do not have potential energy, just kinetic energy. FALSE

They have both.

Valencia electrons are the last electrons in the last layer. They have as much energy as possible and are responsible for forming bonds with other elements.

Emily floats a note across a river to Dylan instead of directly passing it from her hand to Dylan's hand. If, in this scenario,

slega [8]

Answer: The Note

Explanation: Neurotransmitters are endogenous chemical substances that transmits signals through a NEUROMUSCULAR JUNCTIONS.

The signals are transmit from one NERVE CELL TO THE TARGET POINT such as Muscle cell,gland cell etc. Neurotransmissiom require the presence of synapse(the structure or medium through which neurosignals which can be an electrical or chemical signals to pass through).
