Which of the following actions would decrease global warming?
Select one:
Decreasing the amount of methane in the air.

Increasing the amount of oxygen in the air.

Increasing the amount of water vapor in the air.

Decreasing the amount of nitrogen in the air.

Answers

Answer:

Decreasing the amount of methane in the air

Explanation:

Methane is a powerful greenhouse gas, which absorbs the sun's heat and doesn't allow it to escape therefore contributing to global warming

Decreasing the amount of methane in the air would decrease global warming. Therefore, option (A) is correct.

What is global warming?

Global warming is the gradual increase in the Earth's average surface temperature, primarily due to the buildup of greenhouse gases in the atmosphere, such as carbon dioxide and methane. These gases trap heat and prevent it from escaping into space, leading to a warming effect on the planet.

The consequences of global warming are far-reaching and potentially catastrophic, including rising sea levels, more frequent and severe weather events, loss of biodiversity, and impacts on human health and well-being.

To address global warming, it is essential to reduce greenhouse gas emissions by transitioning to cleaner and more sustainable sources of energy, improving energy efficiency, and adopting more sustainable land use practices. Addressing global warming requires a collective effort from individuals, communities, businesses, and governments around the world.

Action Potential: Relative refractory period
In a neuron, there is a period of time called the absolute refractory period where it is impossible for an action potential to
begin. This corresponds to the change in membrane potential from +30 to -70 mV, or the repolarization phase. Towards the
end of the repolarizing phase, there is a relative refractory period where it is difficult, but not impossible, for another action
potential to begin. Using the time slider function, which of the following segments in the neuron would correspond to a
relative refractory period?

Answers

A second action potential can be triggered during the relative refractory phase, but it will need a stronger stimulus to do so than the first time. Refractory times are brought on by the inactivation gate of the Na+ channel.

What Action Potential related to Relative refractory period?

The axon has a tougher time producing successive action potentials during this time period, which is referred to as the refractory period, as a result of these transient alterations.

As a result, the refractory period restricts the quantity of action potentials that a certain nerve cell can generate in a given amount of action potentials time.

If enough powerful stimuli are applied to the neuron after the absolute refractory time, Na+ channels start to recover from inactivation and the neuron may respond once again by generating action potentials.

Therefore, A stimulus that is stronger than usual is required to generate neuronal activation during the relative refractory period.

A lever used to lift a heavy box has an input arm of 4 meters and an output arm of 0.8 meters. What is the MA of the lever?

Answers

Answer:

Mechanical advantage = 5

Explanation:

Given the following data;

Length of input arm = 4 meters.

Length of output arm = 0.8 meters.

To find the mechanical advantage;

[tex] Mechanical \; advantage = \frac {Length \; of \; 1nput \; arm}{Length \; of \; 0utput \; arm} [/tex]

Substituting into the formula, we have;

[tex] Mechanical \; advantage = \frac {4}{0.8} [/tex]

Mechanical advantage = 5
