Answer:

Antibodies are made up of light chain and heavy chains. Heavy chain contains one variable region and three constant region while light chain have only one variable region and one constant region.

The variable region of the light chain and heavy chain of the antibody together makes the antigen-binding site called paratope which binds to their target antigen by non-covalent bond.

Epitope is the portion of an antigen that is recognized by the antibody and then the antibody binds to the epitope of antigen through its paratope region and helps in the killing of antigen.

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.

Match the type of ELISA with what it is used to detect. Question 2 options: detects presences and concentration of antigen/prote

Phoenix [80]

Answer:

ELISA is a technique of enzyme linked immunosorbent assay.

Explanation:

The full form of Elisa is enzyme linked immunosorbent assay. The ELISA technique is a boichemical technique that is used to measure the amount of protein or the antibody in a solution and is divided into three types :

Competitive ELISA
Direct ELISA or Sandwich ELISA
Indirect ELISA

1. Indirect ELISA --- detects the presences and concentration of the antibody.

2. Sandwich Elisa or Direct ELISA --- detects the presences and concentration of the antigen/protein.

Vaccination has been shown to cause autism.Select one:TrueFalse

Mariulka [41]

As we know vaccines have been a very controversial topic, and one of them is autism, even when this has been proved false and the original paper where it was published the study retracted, there still a number of people who argue that this is true, even when evidence in favor of vaccine safety is overwelming. Therefore the correct answer is false.

erastovalidia [21]

Answer:

The evolution of the peppered moth is an evolutionary instance of directional colour change in the moth population as a consequence of air pollution during the Industrial Revolution. ... Later, when pollution was reduced, the light-coloured form again predominated.
