its like the study of parasitic orgamisms
Explanation:
<span>It
is important to characterize and identify unknown environmental bacteria
because it is a potential pathogen. This means that it could be harmful to
anyone. Thus, it is necessary to characterize and identify them in order to
distinguish one organism from another and to group similar organisms by
criteria of interest. Hence, bacteria are everywhere and they are part of our
environment and even of us and through. Through identifying them can help us
determine the cause of a disease or to test if a certain food is safe to eat or
simply to know what is present in a certain ecosystem. </span>
Some rivers begin in mountains or hills, where rain water or snowmelt collects and forms small channels, . At first, the channels are small and are called rills. As more water enters the channels they grow forming gullies (larger channels). The streams in the gullies eventually become big enough to form a river
Answer:
Changes that occur in species, over a long period of time and that include the the replacement of unfavorable characteristics by helpful variations lead to evolution (second option).
Explanation:
Evolution, in terms of biology, consists of the genetic, anatomical and functional changes that occur in individuals of different species, acquiring useful characteristics that replace unfavorable characteristics, due to processes such as natural selection, proposed by <u>Charles Darwin</u>.
<u>Biological evolution</u> raises the existence of a common ancestor, from which all current known species are known, and an evolutionary line for each of those species. Evolution is considered the basis of <u>biodiversity</u>, due to the genetic changes it has produced over many years.
