Scilla [17]3 years ago

7 0

Answer: B. Vacuoles, cell membrane, nucleus, mitochondria

Explanation:

Cell walls only belong to plants, and chloroplasts also only belong to plants. Besides that everything else belongs to both, and that means that B is the only right answer. And I have a advise for you If they ask you a question like something like this In both plant and animal cells, the need to produce energy is carried out by the function of the: the answer is mitochondria

Hope it helps

Santos and Lüderitz are the same distance from the equator, and both cities

Hoochie [10]

Answer:

The difference in altitude between these two regions.

Explanation:

As you can see in the question above, Lüderitz and Santos are two regions that are the same distance from the equator, which indicates that the two regions have the same latitude and are in tropical zones. In addition, the two regions are close to the ocean, but the air in Lüderitz is cooler.

This indicates that there is a difference in altitude in these regions and Lüderitz has a higher altitude than Santos, which is why Lüderitz's air is colder and Santos's is hotter.

Altitude is a geographic term that represents the distance of a region in relation to the level of the sea. The higher the altitude, the greater the distance.

The higher the altitude of a region, the colder its air will be. This is because in high altitude regions, air is thin and has a small capacity to retain heat.

Explain two ways materials can enter the cell through passive transport. Include in your answer: the types of substance that is

blsea [12.9K]

Answer:

Osmosis and facilitated diffusion are two forms of passive transport that are integral to cellular transport mechanisms.

Explanation:

Cells surrounded by a bilipid layer or plasma membrane are amphiphilic, with their polar, hydrophilic lipid heads facing outward, while their hydrophobic non-polar lipid tails facing each other inward.

Although lipid-soluble molecules travel quickly through the bilayer, traveling across its surface into the cell is often difficult for charged and large molecules. Thus, transport proteins, pores and gated channels, transmembrane channels, embedded within the membrane, help to preserve selective permeability.

Across plasma membranes as a form of passive transport in cells, substances move via:

osmosis - water molecules readily pass through the membrane; the molecules move from high concentration regions to low concentration regions at will through the membrane- they move down their concentration gradient
facilitated diffusion - channel proteins allow charged ions to move across the membrane. Sodium ions are able to pass freely through specialized sodium channel pores into some cells. These channels always remain open- the ions move down their concentration gradient.
