Minerals which are good conductors of electricity are described below.
Explanation:
- metals tend to be highly efficient conductors of heat and electricity. The vast majority of elements on the periodic table are metals, and most of these fall into one of five families: alkali metals; alkaline earth metals; the very large transition metals family; and the inner transition metal families, known as the lanthanides and actinides.
- Metals are lustrous or shiny in appearance, and malleable or ductile, meaning that they can be molded into different shapes without breaking. Despite their ductility, metals are extremely durable and have high melting and boiling points. They are excellent conductors of heat and electricity, and tend to form positive ions by losing electrons.
Answer:
The innate or nonspecific immune system includes two lines of defense in the human body. Non-specific means that it does not act on the specific pathogen. It works equally to keep all types of pathogens such as bacteria, viruses, parasites et cetera out of the body.
The first line of defense includes physical barrier which prevents the entry of pathogens into the body. It includes skin, respiratory tract, gastrointestinal tract, cilia, nasopharynx, eyelashes, and body hairs.
It also includes chemical barriers such as mucus, gastric acid, bile, tears, sweat, and saliva.
The second line of defense includes anti-inflammatory responses, fever, and nonspecific cellular responses such as phagocytes, macrophages, complement system et cetera.
Thus, the virus has to pass physical, chemical, and nonspecific cellular responses of the body in order to infect the body.
Answer: The correct answer is- C) vacuole.
Large central Vacuole is a specialized fluid filled organelle, present only in plant cell. It is primarily involved in providing support and shape to the plant cell by maintaining the turgor pressure ( a hydrostatic force that is produced due to the cell contents against the inner side of the cell wall). The central vacuole stores water ( that flows through osmosis) and maintains turgor pressure in a plant cell.
Turgor pressure provides mechanical support and helps in the growth and development of plant.

Answer:
When the level of release of carbon dioxide during respiration and use of carbon dioxide during photosynthesis this results in a compensation point. At compensation point the net available carbon dioxide to phototrophs becomes zero. As, carbon dioxide is the chief ingredient for photosynthetic products like glucose and oxygen. These products are used up during the process of respiration. When the rates of two processes photosynthesis and respiration becomes equal. Phototrophic organisms will not be able to compensate for lack of carbon dioxide levels. Phototrophs will not be able to produce their food in the form of glucose and hence will not be able to respire too. This will result in lack of overall available food from phototrophs and lack of available oxygen for respiration. This will result in decline of organisms on earth.
