Answer:
I'm not 100% sure but I think its A. Here is an article I found on it. I might be wrong.
Answer:
The correct answer is "Darwin's theory of evolution is based on the premise of survival of the fittest; antibiotic-resistant microorganisms are selected by overuse of antibiotics".
Explanation:
Darwin's theory of evolution states that advantageous traits in living beings are selected under the premise of survival of the fittest, where the living beings with the advantageous traits are more likely to survive and reproduce. Darwin's theory of evolution explains the spread of antibiotic-resistant microorganisms, because resistance to antibiotics is an advantageous trait for microorganisms that are constantly in contact with antibiotics. The irresponsibly use of antibiotics leads to the spread of antibiotic-resistant microorganisms, because microorganisms that are naturally resistant to antibiotics are constantly selected and can reproduce and prosper.
Organization of Cells
Biological organization exists at all levels in organisms. It can be seen at the smallest level, in the molecules that made up such things as DNA and proteins, to the largest level, in an organism such as a blue whale, the largest mammal on Earth. Similarly, single celled prokaryotes and eukaryotes show order in the way their cells are arranged. Single-celled organisms such as an amoeba are free-floating and independent-living. Their single-celled "bodies" are able to carry out all the processes of life, such as metabolism and respiration, without help from other cells. Some single-celled organisms, such as bacteria, can group together and form a biofilm. A biofilm is a large grouping of many bacteria that sticks to a surface and makes a protective coating over itself. Biofilms can show similarities to multicellular organisms. Division of labor is the process in which one group of cells does one job (such as making the "glue" that sticks the biofilm to the surface), while another group of cells does another job (such as taking in nutrients). Multicellular organisms carry out their life processes through division of labor. They have specialized cells that do specific jobs. However, biofilms are not considered multicellular organisms and are instead called colonial organisms. The difference between a multicellular organism and a colonial organism is that individual organisms from a colony or biofilm can, if separated, survive on their own, while cells from a multicellular organism (e.g., liver cells) cannot. Next time fraze your question better. It took me a secound to understand what you were trying to ask
The Earth's Mass is what directly influences its gravitational pull. The gravity produced by the earths mass keeps people grounded on earth and the moon in orbital rotation by pulling to the center of mass, the Earth's core.
