Integral proteins are embedded in the phospholipid layer, and can sometimes form protein channels that let ions and other small molecules through.

Answer:

The correct answer is integral membrane proteins.

Explanation:

The plasma membrane is the outer membrane of the cell which is selectively permeable. The small polar molecules and hydrophobic molecules can go through the lipid bilayer, but ions and large polar molecules cannot go through. There are some Integral membrane proteins present in the plasma membrane that enable ions to pass through the plasma membrane by active or passive transport.

Thus, the correct answer is integral membrane proteins. Ions generate electrochemical gradient so they are generally used in secondary transport systems.

Thus, the correct answer is integral membrane proteins.

4. Discuss the difference between solar flares and CME's.
brilliants [131]

Answer:

CMEs are giant clouds of particles from the Sun hurled out into space, while flares are flashes of light—occurring in various wavelengths—on the Sun.

All three occur in the corona. The biggest difference is the cause. The solar wind is a constant flow of particles from the sun’s corona due to their high energy gained from the sun’s interior, it’s like being boiled off. CME’s and flares are the result of “explosive” releases of energy from the sun’s magnetic field.

One can think of the explosions using the physics of a cannon. The flare is like the muzzle flash, which can be seen anywhere in the vicinity. The CME is like the cannonball, propelled forward in a single, preferential direction, this mass ejected from the barrel only affecting a targeted area.

Based on your understanding of the hydrologic cycle and oceans, pick the correct statement from the choices below.
IceJOKER [234]

Answer:

Neither A nor B is correct

Explanation:

Hydrologic cycle is the sequence of different conditions through which the water passes from oceans to clouds, precipitates as rains, comes to the rivers and finally reaches the ocean.

This first statement in the question said that water will end up in the river which is not true because water from the river ultimately ends in the oceans because all the rivers terminate in the oceans finally.

The second statement is also wrong because when water from one ocean vaporizes and becomes cloud, it can travel large distances as clouds in the effect of wind and thus may get precipitated in the form of rain in some other part of the world. So, it is not necessary that the water will end up in the same ocean.
