Can someone please help me with 1 evolution question ?
geniusboy [140]
Antibiotic resistance is a consequence of evolution via natural selection. The antibiotic action is an environmental pressure; those bacteria which have a mutation allowing them to survive will live on to reproduce. They will then pass this trait to their offspring, which will be a fully resistant generation.

At which type of plate boundary do tectonic plates slide past each other?
melamori03 [73]
The answer would be conservative plate boundaries.

They occur where plates slide past each other in opposite directions, or in the same direction but at different speeds. Friction is eventually overcome and the plates slip past in a sudden movement. The shockwaves created produce an earthquake.

I hope this helped and is correct! :)
