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 less light is transmitted. That means light is being absorbed. Due to the fact that bonds absorb different frequencies of light, the peaks tell you what kinds of bonds are present from which we can identify the elemental composition.

As skin cells move toward the surface of the body, they produce a protein that reduces water loss. This process is called

fomenos

Answer:

As skin cells move toward the surface of the body, they produce a protein that reduces water loss. This process is called Keratinization.

Explanation:

Keratinization is a process which changes the stratum corneum of the skin to a hard cover which provides protection.

The process of keratinization involves polymerization of keratin polypeptides. The keratin polypeptides gets polymerized into intermediate filaments of keratin. Each of the intermediate filament of keratin constitute around 30,000 polypeptides of keratin.

use the following term to create a concept map: Chromosome, duplication, cytokinesis, prokatyote, mitosis, cell cycle, binary, f

Law Incorporation [45]

Answer:

The words depict the phenomenon of cell division in prokaryotes and eukaryotes.

The possible concept map that could be drawn from these words could be:

Number 1:

Cell cycle in a eukaryote occurs through the process of mitosis (or meiosis) and chromosomes duplicate by this process. Cytokinesis separates the two daughter cells by separating the cytoplasm of the two cells.

Number 2:

Cell cycle in a prokaryote involves the method of binary fission.
