Answer:
Knowledge gain through observation and experimentation.
Explanation:
Science is the systematic study of the structure and behaviour of the physical and natural world through observation and experiment. That knowledge which can be gain through observation and experimentations is considered as scientific knowledge and those knowledge which can be attain through other sources not observation and experiments is known as non-scientific knowledge so we can say that observation and experiments provide scientific knowledge.
The right answer is DNA. That consist of a sugar, deoxyribose, a phosphate and a nitrogen-containing base
Answer:
The correct answer would be - biological species concept.
Explanation:
The biological species concept is a concept of speciation or how a species forms in nature. According to this, a species is the group of the population that can naturally or potentially interbreed with each other, not on the basis of their physical similarities or habitats.
The physical appearance could be useful as recognizing a species but not defining it. As neanderthals show very little or no gene flow with a modern human it means they do not belong to the same species as modern homo sapiens.
Thus, the correct answer is- biological species concept.
Urbanization is defined as “the process of making an area more urban” or an increase in the amount of people living in towns or cities. Industrialization is defined as “the development of industries in a country or region on a wide scale” meaning a strong military with modern weapons, factories to create things, modern cars and boats etc. Urbanization and industrialization put a strain on the environment because of carbon gases emitted, effectively warming the earth up, destruction of trees which lowers our overall oxygen available, destruction of animal homes which will kill animals or cause unwanted interactions between humans and animals, and the pollution of natural resources such as local ponds, streams or the ocean.
