Answer:
1. physical and chemical barriers
2.non-specific innate response
3. specific adaptive responses
Explanation:
When pigments are mixed together, more colors are being absorbed which results to few colors that will be reflected. Each pigment absorbs and reflects light which results to the "color" or hue that we see. When these pigments are to be mixed, then more wavelengths would be absorbed which results to lesser reflection.
Active and passive humoral immunity are both mechanisms of adaptive immunity that use antibodies. yes this is true
- Our adaptive immune system protects us from infection-related mortality. An new-born born with a significantly compromised adaptive immune system may die shortly unless extreme steps are taken to isolate it from a wide range of infectious agents such as bacteria, viruses, fungi, and parasites.
- The purpose of adaptive immunity is to eliminate invading infections as well as any harmful chemicals they create. Because these reactions are damaging, it is critical that they only occur in response to molecules that are alien to the host and not to molecules that are native to the host. The adaptive immune system's capacity to identify what is foreign from what is self is a fundamental feature.

Atom refers to a tiny particle, which is the basic building block of all the substances and whose properties determine the characteristics of an element made up of only of those atoms.
All the living and nonliving matter in this world are made up of atoms and elements. Everything in the universe is matter, and matter comprises elements. Some of the elements are important to living things.
Elements are formed by atoms, and atoms comprise protons, electrons, and neutrons. The number of protons in an element's atom signifies the identity of the element.
