Answer:

Proteins are large, complex molecules that play many critical roles in the body. They do most of the work in cells and are required for the structure, function, and regulation of the body's tissues and organs. These proteins provide structure and support for cells. On a larger scale, they also allow the body to move.

Explanation:

three major roles of proteins are:

hormones. Many hormones are protein in nature; hormones control growth and metabolic activities of the body.

catalytic activities. Enzymes are globular protein.

Transport of oxygen.

Blood Clotting.

Immunity.

Muscles contractility.

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.

Assuming a cell has just completed DNA synthesis, place these stages/steps in the cell cycle in the correct order of occurance b

shusha [124]

Answer:

The division of eukaryotic cell is done through various phase known as cell cycle.

Explanation:

The two basic phases of cell cycle is Interphase and Mitosis, that can be further divided into:

1) G2 Phase; G2 checkpoint ( Interphase stage)

2) Prometaphase (Mitotic Phase)

3) Anaphase (Mitotic Phase)

4) Telophase (Mitotic Phase)

5) cytokinesis (Mitotic Phase)

6) G1 Phase; G1 checkpoint ( Interphase stage)

After G1 phase there would be again S phase in which DNA replication occur.
