Answer:

She was able to represent something small in a larger way.

Explanation:

Obviously if the bacteria need to be viewed with a microscope, they are extremely small. Darla likely does not have access to a microscope at her house, so using the macaroni and string, she made her own way of "seeing" the bacteria, but in a larger way. B is false because bacteria are small, not large. C is false macaroni do not need to be viewed with a microscope; in fact, this will probably allow you to not see them very well at all. D is false because macaroni wouldn't really show any patterns.

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:

<em><u>Osmosis and facilitated diffusion</u></em> 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:

  1. 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
  2. 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.

Why does the moon appear to change its shape as seen from earth?
Fiesta28 [93]
D.
Different parts of the sun lit moon become visible as the moon revolves around earth

This happens because as the moon orbits earth the sun will project light towards it and the reason it seems to glow is because of the reflected light since the moon is white it reflects more light. Think of it as a day and night cycle except it’s on the moon when it becomes night on earth the part of earth facing towards the sun will be lit aka day/morning/afternoon etc
The part of the earth facing away will be dark aka night/midnight/etc.
