Answer: Ecological succession is the process that describes how the structure of a biological community (that is, an interacting group of various species in a desert, forest, grassland, marine environment, and so on) changes over time.
Explanation:
The efficiency is equal to the output work of the machine / actual work the machine done * 100%. So the actual work is 50,000/80%=62,500 jewels.
Answer:
The active smokers and those getting exposed, that is, passive smokers are at enhanced threat of bacterial infections. Getting exposed to tobacco smoke enhances vulnerability to respiratory tract infections, comprising pneumonia, tuberculosis, and Legionnaires disease.
Smoking compromises the anti-bacterial activities of leukocytes incorporating monocytes, neutrophils, B cells, and T cells, thus, demonstrating the mechanism for enhanced risk of infections.
Answer:
d. a compound
Explanation:
Rust is also known as <em>"iron oxide."</em> It is a<u> compound</u> that is very common around the world. This compound is formed because <em>iron</em> readily combines with the element,<em> oxygen. </em>This is the reason why it is not common to find pure iron in the environment. The process of an<em> iron rustin</em>g is called "corrosion."
The speed of rusting largely depends on the<em> electrolytes</em> present. Rain is considered a<u> better electrolyte that speeds up the rusting of the iron</u> than pure water. Thus, this is the reason why Bill's hammer had rusts on it the next morning.
