What evidence do the positions of the peaks and dips in its spectrum provide about an object? A. expansion B. elemental composit
Andreas93 [3]

Given what we know about the use of spectrums, we can confirm that the positions of peaks and dips provide information as to the elemental composition of the object in question.

The question asks about the dips and peaks of a spectrum, which allows us to assume we are dealing with Infrared spectroscopy and IR spectrums. This is defined as the measurement of how certain matter interacts with infrared radiation.

These graphs are used to measure how this matter absorbs, reflects, or even emits said radiation. Therefore, the use of spectrums allows us to infer as to the chemicals present or functional groups of an object, and therefore its elemental composition.

When looking at the spectrum graph, we will see that at times the curve dips down, which indicates that <u><em>less light </em></u>is transmitted. That means light is being absorbed. Due to the fact that bonds absorb different frequencies of light, <u>the </u><u>peaks </u><u>tell you what kinds of </u><u>bonds </u><u>are present from which we can identify the </u><u>elemental composition</u><u>.</u>

Which statements are true of receptor-mediated endocytosis?
Rufina [12.5K]

The statements that  are true of receptor-mediated endocytosis is that It allows the internalization of extracellular substances in clathrin-coated vesicles.

<h3>What is receptor-mediated endocytosis?</h3>

Receptor-mediated endocytosis  can as well be regarded as the clathrin-mediated endocytosis,  which can be explained as the process by which cells absorb metabolites as well as  hormones, proteins.

It should be noted that in some cases of viruses through the inward budding of the plasma membrane, however the process of endocytosis”  can be seen as one that entails  both the ingestion of large particles  whic could be bacteria as well as the uptake of fluids or macromolecules in small vesicles.

In conclusion, when it take in large moplecules it is known as  phagocytosis (cell eating) , in receptor-mediated endocytosis , there is a room for the internalization of extracellular substances in clathrin-coated vesicles.

Therefore, the first option is correct.
