Explanation:
(a) Silicosis is a situation in which the person work in stone grinding industries, they tend to inhale the crystalline silica dust, which is also a part of sand and rock. It affects the human lungs and can cause lung fibrosis.
(b) Benzoates, Nitrates, sulphites are the food preservatives chemicals which are used mostly in food preparation so that it can be stored for long period. These chemicals are harmful for human and can cause disease in the human. They can cause severe asthma in humans. The international agency for the research of cancer has reviewed ingested nitrates and nitrites are probably carcinogenic to humans.
(c) Industrial pollution cause water and soil pollution. Industrial pollution is the release of wastes and pollutants generated by the industrial activities into the natural environmental including air, water and sand. It causes chronic health problems. Polluted air cause lung related issue and polluted water causes abdominal pain, diarrhea in humans
Answer:
As the choices are not given, so let's have a look at the Ramsar Convention in general.
Explanation:
In 1971, different countries around the globe signed a treaty in Ramsar, Iran for the conservation and sustainable usage of different wetlands around the world.

Answer:
Polygenic inheritance
Explanation:
When multiple genes present at different loci on chromosomes regulate a single genetic trait, the trait is said to be polygenic and the inheritance is a polygenic inheritance. The phenotype of the individual is regulated by an allele of each gene in an additive manner. The sum total of phenotypic effects of each allele of all the genes determines the final phenotype of the individuals.
These traits not present in discrete contrasting pairs (such as tall and short) but exhibit quantitative variations. For example, skin color in humans is regulated by multiple genes and the phenotype of the individual ranges from very light to very dark with many intermediates in between.
