What do the results of the agar blocks indicate about the relationship between cell size and diffusion rate?

Irina-Kira [14]

Answer:

s the cube size increases, the surface-area-to-volume ratio decreases (click to enlarge the table below). The vinegar can only enter the cube through its surface, so as that ratio decreases, the time it takes for diffusion to occur throughout the whole volume increases significantly.

There are two basic ways that substances can cross the plasma membrane: passive transport, which requires no energy; and active transport, which requires energy. Passive transport is explained in this section and Active transport is explained in the next section, Active Transport and Homeostasis.

Plants that carry out crassulacean acid metabolism (cam) differ from c4 plants in that they do not contain rubisco. they do not

Serggg [28]

Plants that use crassulacean acid metabolism (CAM) photosynthesis repair CO2 at night, when their stomata are open. CAM plants stock the CO2 typically in the method of malic acid via carboxylation of phosphoenolpyruvate to oxaloacetate, which is then concentrated to malate. Decarboxylation of malate during the day discharges CO2 inside the leaves, therefore permitting carbon fixation to 3-phosphoglycerate by RuBisCO.

Lipid polymers are often created by numerous non-polar fatty acid chains with a polar head lined up. Which is the best explanati

fomenos

Polymers are macromolecules composed of similar monomers joint through chemical bonds. <em>Lipids </em><em>are not composed of similar </em><em>basic units</em><em>, so they are </em><em>not</em><em> considered to be </em><em>polymers</em><em>. There is no formation of a polymer lipid. </em>

------------------------------------------------

<em>Together with proteins, carbohydrates, and nucleic acids, </em><em>lipids</em><em> are essential </em><em>components</em><em> of </em><em>biological structures</em><em> and are part of the </em><em>biomolecules </em><em>group. </em>

When talking about <u>polymers</u>, we are referring to molecules composed of multiple similar units, the monomers. When many monomers join through chemical bonds, through the polymerization process, they form a polymer. These units do not need to be identical.

According to the polymer definition, <em>polysaccharides, proteins, and nucleic acids are polymers</em>.<em> </em><u><em>Lipids</em></u><u><em> are </em></u><u><em>not polymers</em></u> because they are not composed of a repeated sequence of basic units.

Lipids are individual medium-sized molecules. There are different types of lipids: triacylglycerols, wax esters, phosphoglycerides, sphingolipids, and sterols.

According to their structure:

Simple lipids ⇒ Composed of an alcohol molecule and fatty acids.
Complex lipids ⇒ They are composed of alcohol, fatty acids, and different non-lipidic components, such as<em> phosphates, amino acids, glucyds, amines</em>, etcetera. These are the amphipathic molecules.

Membrane lipids are amphipathic molecules with hydrophilic heads -negatively charged phosphate group- and hydrophobic tails. In membranes, they are arranged with their hydrophilic polar heads facing the exterior and the interior of the cells, while their hydrophobic tails are against each other, constituting the internal part of the membrane.
