Answer:

The answer will be C. Variable

Explanation:

The answer will be C because A response is a reactant for the plant and the question is asking about the light. B is incorrect because stimulus is how a plant reacts to nature for example gravitrophism and  thingatropism also its asking about the light not the plant. D is incorrect because... come on now does it even make sense XD

Hope this helps

Answer:

stimulus

Explanation:

begin by eliminating answers that don't make sense, such as "chosen one", then decide if each of the other ones make sense for it, the flower is responding to the lamp, so that means the lamp is not the response. It is the stimulus, because it is affecting the flower.

Neither n2 nor o2 are greenhouse gases because
Katyanochek1 [597]

Neither N₂ or O₂ are greenhouses gases because they do not cause the greenhouse effect.

<h3>What are greenhouses gases?</h3>

Greenhouse gases trap heat in the atmosphere causing the temperature of the planet to rise.

Greenhouse gases cause the greenhouse effect.

<h3>What is the greenhouse effect?</h3>

The greenhouse effect is the warming up of the planet due to greenhouse gases.

Greenhouse gases include

  • carbondioxide
  • methane
  • nitrous oxide and
  • water vapour

So, neither N₂ or O₂ are greenhouses gases because they do not cause the greenhouse effect.

For each pair; which has higher kinetic energy?
RideAnS [48]

Explanation:

Kinetic energy is defined as the energy obtained by an object due to its motion. Whereas energy obtained by an object due to its position is known as potential energy.

(a)   When a sled is resting at the top of a hill then it means the sled in not moving. Hence, then it has only potential energy. But when a sled sliding down the hill  then it is moving from its initial position.

Hence, when a sled is sliding down the hill then it has higher kinetic energy.

(b)    When water is above the dam then it only has potential energy but when the water falls over the dam then it has higher kinetic energy.

The decomposition of dinitrogen pentaoxide has an activation energy of 102 kj/mol and \delta ? h°rxn = + 55 kj/mol. what is the
posledela
A positive cahnge of enthalpy, ΔH rxn = + 55 kJ/mol, for the forward reaction means that the reaction is endothermic, i.e. the reactants absorb energy and the products are higher in energy.

Activation energy is the difference in the energy level of the reactants and the peak in the potential energy diagram (the energy of the transition state).

For an endothermic reaction, the products will be closer in energy to the transition state than what the reactans will be; so, the activation energy of the reversed reaction is lower than the activation energy of the forward reaction.

Activation energy of reverse and forward reactions is related by:

Activation energy of reverse rxn = Activation energy of forward rxn - ΔH rxn

=> Activiation energy of reverse rxn = 102 kJ/mol - 55 kJ/mol = 47 kJ/mol

Answer: 47 kJ/mol
