11. Air quality measures
snow_tiger [21]
Air quality is a measure of how clean or polluted the air is. Monitoring air quality is important because polluted air can be bad for our health—and the health of the environment. Air quality is measured with the Air Quality Index, or AQI. The AQI works sort of like a thermometer that runs from 0 to 500 degrees.

BEST ANSWER GETS BRAINLIEST!!!!!
White raven [17]

Answer:

"<em>Methane is a greenhouse gas, so its release would likely increase global warming."</em>

Explanation:

Methane is a greenhouse gas, so its release would likely increase global warming.

This is the only one that is both "true," and that applies to climate scientists.

Methane is toxic to marine organisms and would damage the ecosystem if released by killing species.

We are asking about <u><em>climate scientists.</em></u>

This would lead to massive pollution of drinking water.

 We do not get drinking water from the ocean (except in some desert countries).

We want to extract and use this gas as a fuel source, but it would be lost to the environment through this process.

Again, climate scientists.

When the voltage of a plasma membrane shifts from +30mv towards 0 mv, we say the cell is
stealth61 [152]
When voltage of a plasma membrane shifts from +30mV towards 0mV, we say cell is repolarizing. Repolarization results from the movement of positively charged K+ ions out of the cell. This repolarization phase of an action potential results in hyperpolarization, attainment of a membrane potential that is more negative than the resting membrane potential.

Explain the mechanisms for movement of materials across cellular membranes anatomy
trapecia [35]
There are 2 types of transport mechanisms that involve the movement of materials across the cellular membrane:

1. Passive Transport Mechanisms which is the movement of materials that does not require energy. Instead the movement relies on the permeability of the cell. Under this are three kinds of passive transport mechanisms:

a. Simple Diffusion: 
- the movement of materials from a region of higher concentration to lower concentration. No external energy is necessary for the movement. The materials supply the energy themselves. 

b. Facilitated Diffusion:
- This differs from simple diffusion because the movement is facilitated by proteins that make up the structure of the membrane. The proteins include channel proteins that allow ions and smaller molecules to cross the membrane. The other protein are the carrier proteins, which bind to materials like sugar molecules and move it across the membrane.  

c. Osmosis:
- This is the diffusion of water across the membrane. Osmosis moves water from regions where there are more water molecules of water per volume to regions where there are less water molecules per volume.  

2. Active transport on the other hand is a movement mechanism that requires energy. It uses the energy to send materials against the direction it is coming from through simple diffusion. This mechanism is used in a way to keep unwanted ions or other materials out of the cell.
