Each statement illustrates an example of qualitative data since there is no mention of any quantitative value.
<h3>What is meant by qualitative analysis? </h3>
The determination of non-numerical values which gives information about the species participating in a chemical reaction is called qualitative analysis. For example, analysing the products of the reaction or the time it takes for product formation.
This kind of analysis is not a reliable analysis like the quantitative analysis. In quantitative analysis, we have to analyze the amount of energy consumed or the amount of product formed.
No such analysis is made in the case of qualitative analysis which makes this kind of analysis less reliable and data-oriented.
Therefore, the statements mentioning which sample is heavier, which sample takes longer to react and which sample increased the temperature by 3 degrees are all statements which are examples of qualitative analysis.

Macrophages
Using the receptors on their surface and through the facilitation by immunoglobulins that attach to the foreign matter, macrophages 'hold' the foreign bodies in the body and 'ingest' them through phagocytosis. Lysozymes in the cells then in 'digest' the foreign matter.

B. by consuming plants
Explanation:
A lot of people are getting tricked by this question because everyone knows nitrogen is the most prevalent gas in air. But that's not what the question is asking. The USABLE FORM of nitrogen enters our bodies by consuming plants.
Answer:Aquaponics is a cooperation between plants and fish and the term originates from the two words aquaculture (the growing of fish in a closed environment) and hydroponics (the growing of plants usually in a soil-less environment). Aquaponic systems come in various sizes from small indoor units to large commercial units.
Explanation:
Electronegativity.
If the difference in electronegativity for the atoms in a bond is greater than 0.4, we consider the bond polar. If the difference in electronegativity is less than 0.4, the bond is essentially nonpolar.
