What is the key characteristic of lipids that enables them to keep substances form penetrating cell membrans?
The key characteristic of lipids that enables them to prevent substances from penetrating cell membranes is their hydrophobic nature. Lipids are primarily composed of long hydrocarbon chains that are nonpolar, making them insoluble in water. This hydrophobic property allows lipid molecules to form a bilayer structure in cell membranes, creating a barrier that restricts the passage of polar and charged substances while allowing selective permeability for certain molecules.

What is the key characteristic of lipids that enables them to keep unwanted substances from penetrating cell membranes?
The key characteristic of lipids that helps prevent unwanted substances from penetrating cell membranes is their hydrophobic nature. Lipids are mostly nonpolar molecules, which means they repel water and do not mix well with aqueous environments. This hydrophobic property forms a selective barrier, allowing only certain small, nonpolar substances to pass through while restricting the entry of larger or polar molecules. As a result, lipid bilayers effectively maintain the integrity of the cell by controlling what can enter or exit.
Which term best describes a specially developed characteristic that enables an organism to live in a specific enviorment?
"adaptation"
What type of bond produces substances that have luster?
Metallic bonds produce substances that exhibit luster. In metallic bonding, electrons are delocalized, allowing them to move freely throughout the metal lattice. This electron mobility enables metals to reflect light effectively, resulting in their characteristic shiny appearance. Additionally, the closely packed arrangement of metal atoms contributes to this luster.
Is binocular vision a characteristic of all primates?
Yes, binocular vision is a characteristic of all primates. It helps in depth perception and enables them to accurately judge distances. This trait is particularly advantageous for primates living in complex environments such as forests.
What is the property of a cell membrane that allows particles to move through it?
The property of a cell membrane that allows particles to move through it is its selective permeability. This characteristic enables the membrane to regulate the passage of substances, allowing certain small or nonpolar molecules to diffuse freely while restricting larger or charged particles. Additionally, membrane proteins facilitate the transport of specific molecules through channels or carriers, further aiding in the selective movement of substances into and out of the cell.
