A. Dietary and functional fiber
An atom that has gained or lost electrons is called an ion
Answer: alternating dark and light bandsof protein filaments
Skeletal muscle fibers contain striations that can be described as alternating dark and light bands of protein filaments. Actin, tropomyosin, and troponin are among the protein filaments. The dark bands are the so-called A bands. Alternating light bands are referred to as I bands.
The molecules that will be labeled will be both proteins and nuclei acids. This is because both proteins and amino acids contain nitrogen. Proteins are large, complex molecules that play many critical roles in the body. They perform many of work in cells and are required for the structure, function, and regulation of the body's organs and tissues. Amino acids are the building blocks of proteins and are made amine groups which contain radioactive nitrogen, while nucleic acids contain nitrogenous bases with radioactive nitrogen.
Answer:
The question lacks options, the options are:
A. commensalism
B. mycorrhiza
C. parasitism
D. symbiosis
The answer is D, symbiosis (mutualism)
Explanation:
Organisms of same or different species interact with one another in their natural environment. The relationship between two organisms interacting with one another is called SYMBIOSIS. Symbiosis can be of different types depending on the effect of the relationship on the involved organisms. Symbiosis can be mutualistic, commensalistic or parasitic.
Mutualism is a kind of symbiosis in which the involved organisms benefit from the actions of one another. This is a case of the association between the root nodules of leguminous plant and rhizobium species.
Rhizobium is a bacteria genus found in the soil. They form nodules by attaching to the root of leguminous plants, which helps the plants to fix atmospheric nitrogen i.e converting gaseous nitrogen to a usable form (ammonia). In return, the plants provide organic acids for the Rhizobia bacteria, which they use as carbon and energy source. Hence, the association is a symbiotic relationship and specifically a mutualistic one.
The answer is no mycorrhiza because it is an association between a FUNGUS and a plant.
