Biochemistry, sometimes called biological chemistry, is the study of chemical processes within and relating to living organisms. By controlling information flow through biochemical signaling and the flow of chemical energy through metabolism<span>, biochemical processes give rise to the complexity of life.

The slab sinks faster and this pulls on the rest of the plate, continuing plate tectonics. Mantle convection creates the instability that allows plate tectonics to get going and helps a little, but it's not thought to be the main driving force
<u>Answer</u>: option B through mutation
<u>Explanation</u>:
- Antibiotic resistance is the phenomena in which the bacteria becomes reistance to a given antibiotic and is no longer killed or harmed by it.
- Bacteria unlike humand divide rapidly and increase in large number. However, each time it divides it has to replicate its genetic material. In the process of replication there is always a chance of introducing an error which is called as a <em>mutation</em>.
- The mutation that occurs in a bacteria can either ber advantageous or disadvantageous. However, amongst the various type of mutations that arise in the bacteria if a particular mutation is conferring resistance to an antibiotic then in such case the bacteris gets selected by natural selection.
- The bacteria having acquired thr resistance is then able to produce more of its progenies with the same antibiotic resistance and thus, this is how the resistance gets propagated.
So, firstly the <em>mutation</em> is the one which gives rise to the resistance which is then spread among the bacterial population by the process of reproduction as well horizontal gene transfer.
Pesticides are harmful substance ranging from the level of
caution, which are slightly harmful, to danger, meaning extremely harmful. When using pesticides, there’s a possibility
that it can enter the body in many different ways that will result to both
acute and chronic health effects.
