Answer:

Option (3).

Explanation:

The molecules may transport from inside and outside of the cell from their region of low concentration to high concentration or vice-versa. Different types of transport process are diffusion, osmosis, primary active transport.

Diffusion occurs naturally in the organism and no energy is required for its transport. The molecules move to the region of lower concentration from its region of higher concentration. The molecules moves along the concentration gradient.

Thus, the correct answer is option (3).

Which of the following best explains why the latitude of a region influences its climate?
Rudik [331]

Answer:

"The latitude of a region determines how much sunlight the area receives" this statement says about why the latitude of a region influences its climate.

Explanation:

The latitude determines the sunlight of the area receives because, the more the latitude the sharper will be angle of the sun's rays which will reach the surface. Means that the rays of the sun are being spread over the broader area. Hence, More the latitude receive will be the less than the lower latitude areas located nearer to the equator. As, we know the sun's ray first strikes over the Earth's surface which is near the equator as these places receive direct solar radiation. At greater latitude the solar radiations gets spread in more area and hence the temperature also reduces.

mario62 [17]

Answer:

No

Explanation:

During cyclic photophosphorylation, electrons are cycled continuously out of and back into the reaction center of PSI. It does not involve PSII and plastoquinone. During non cyclic photophosphorylation, the reaction center of plant photosystem II passes electrons to plastoquinone. The reduced plastoquinone carries electrons to the cytochrome b6f complex. Since PSII and plastoquinones are not included in cyclic photophosphorylation, dichlorophenyldimethylurea would not affect the process.
