A researcher proposes a model of an enzyme-catalyzed reaction in which a reactant is converted to a product. The model is based
lions [1.4K]

Answer: The answer is B: The enzyme's active site binds to and stabilizes the transition state, which decreases the activation energy of the reaction.

Explanation: An enzyme is a biological molecule which speeds up the rate of chemical reactions in the body (reactions within cells). They are proteins.

    The transition state is the transition from substrate to product. The molecule is no longer a substrate but also not yet a product.

The enzyme is able to speed up the reaction by stabilizing the transition state. The transition state's energy is also the activation energy in terms of reaction. The activation energy is the minimum energy that is required to break some bonds of the reactants in order to turn them to products.

Match the human activity and how it increases the greenhouse affect
laiz [17]

Answer:

1. primary cause of human-created carbon emissions = burning fossil fuels

2. destroys natural carbon sinks leading to more carbon dioxide in the air = deforestation

3. emits methane from decomposing matter = waste disposal in landfills

Explanation:

1. "Fossil fuels" are <em>nonrenewable resources</em> that are considered essential for the operation of many factories and industries. <em>Burning them accounts for most of the carbon emissions on Earth</em>, and this leads to<em> "global warming."</em>

2. "Forests" are considered "carbon sinks" because they have a role of <u><em>absorbing the carbon dioxide in the atmosphere</em></u>. Cutting down the trees (deforestation) makes forests barren. It then leads to more carbon dioxide in the air.

3.<em> Waste disposals in landfills contribute to the amount of methane that is released into the atmosphere.</em> Methane is considered a <em><u>potent greenhouse gas</u></em> that affects people's health.

A scientist wants to know if adults prefer watching movies in a theater or in their home. He interviews 500 people leaving a loc
JulijaS [17]

Answer:

The scientist's conclusion is most likely unreliable because he just interviewed people watching movies in the theatre. He should have interviewed an equal number of people from the theatre and from home to get reliable results. According to the scientific method for designing an experiment, the experiment or survey conducted by scientists is not correct. Hence, the scientist's conclusion is wrong because his method of experimentation was wrong.
