I believe it should be the first option
Answer:
It can lead to multiple health hazords like harmful substances and it has a huge waste of rocks and vegatation.
Explanation:
Across the world, mining contributes to erosion, sinkholes, deforestation, loss of biodiversity, significant use of water resources, dammed rivers and ponded waters, wastewater disposal issues, acid mine drainage and contamination of soil, ground and surface water, all of which can lead to health issues in local areas. Some mining methods may have significant environmental and public-health effects.
The body's nonspecific defiance against invading pathogens is known as innate immunity and includes the following:
mechanical barriers and surface secretions
1. The intact skin and mucous membranes of the body. These provide a high degree of protection against pathogens.
2. The sebaceous secretions and sweat of the skin contain bactericidal and fungicidal fatty acids that can kill bacteria and fungi.
3. Normal bacterial flora of the skin may produce various antimicrobial substances such as bacteriocines and acids.
Humoral defence mechanisms
1. Lysozyme. This is an enzyme found in most tissue fluids apart from cerebrospinal fluid, urine, and sweat. It can kill bacteria.
2. Interferon. Inhibits viruses from replicating
3. Complement. This is a heat labile serum that can destroy gram-negative bacteria.
I think the answer to this is B
1a. Pseudopodia means false feet these are irregular projections found in organisms like amoeba,they help the organism in locomotion capture food etc
1b.a good vacuole is a membrane-enclosed cell vacuole with a digestive system,containing material taken up in by the process of phagocytosis.these are found in amoeba,Protozoa,paramecium
2.the ingestion of bacteria or other material by phagocytes and amoeboid protozoans (wasn’t sure for this one so I had to research)
3.amoeba takes in nutrition by the process called phagocytosis.in this process,a solid food particle is first surrounded by pseudopodia (cytoplasmic filled projection of cell membrane) and forms a vacuole called as Phagosome
