Answer:
Burning of fossil fuels???
Explanation:
"As elevation increases, air pressure decreases." could be a good claim. for evidence you could put" when the elevation was 33 feet in ny, the air pressure was 29.92, when the elevation was 594 in chicago, the airpressurewas 29.87, the elevation increased from ny to chicago whil air pressure decreased." for reasoning you could put "The elevation in new york was 33 feet, and the elevation in chicago is greater(594). The air pressure in new york is 29.92, an the air pressure in chicago is 29.87. 29.87 is less than 29.92, therefore the air pressure decreases as elevation increases"or something of that sort. hope this helps!
<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.
Answer:
Relay neurons are found between sensory input and motor output/response. Relay neurons are found in the brain and spinal cord and allow sensory and motor neurons to communicate. Motor neurons are found in the central nervous system (CNS) and control muscle movements.
