Answer:
Wavelength and frequency of light are closely related. The higher the frequency, the shorter the wavelength. Because all light waves move through a vacuum at the same speed, the number of wave crests passing by a given point in one second depends on the wavelength.
Amplitude is the height of a wave which is the brightness of a light or loudness of a sound. So Frequency and Amplitude though are part of a wave are not dependent on each other. Their is no relation between frequency and amplitude.

Answer:
Explanation:
Antibodies are blood proteins produced to combine with and combat specific antigens and foreign substances such as bacteria and viruses.
An antibody which is also known as immunoglobulin is a Y-shaped structure that normally consists of 4 polypeptides which are 2 heavy chains and 2 light chains. This is the structure that makes it possible for antibodies to carry out their double functions which are - Antigen binding and Biological activity mediation.
Each role is executed by different parts of the antibody. That is, the fragment crystallizable region known as the fc region and the fragment antigen binding known as fab fragment.
The fab fragment is an area on the antibody that joins to antigens. It normally consists of one variable and one static domain of each of the light chain as well as the heavy one.
The fragment crystallizable region is the tail area of an antibody that combines with surface receptors and proteins of the complement system.This normally enables the antibodies to activate the immune system
The right answer is to look for cyanosis by determining the color of the baby's chest and abdomen,
Cyanosis refers to the bluish coloration that the skin and mucous membranes take when the blood contains a small amount of oxygen-bound hemoglobin.
When there is little oxygen in the blood, it takes on a dark red color. And when all the vessels (of the whole body or a region of the body) carry low oxygenated blood, then it gives the skin the bluish color characteristic of cyanosis.
Symptoms may be associated with that of cyanosis, depending on what causes it. For example, breathing difficulties, chest pain, fever, heart failure or general fatigue.
