A, b, and c! i’m sorry if you get this incorrect but i’m sure that it’s right
Cells with large numbers of mitochondria have a high energy demand
The area around the rock will have weathered down and the rock will eventually either break or it will fall down the mountain
Telomeres are protective sequences of nucleotides found at the ends of chromosomes,Which become shorter every time a cell divides.
A gradual degeneration of an organism occurs, resulting in ageing.
However, some cells are able to replenish their telomeres using the enzyme telomerase.
Hope this helps! :)
I might be wrong but I think C ( what the wave it traveling through). I think C because a wave medium is the substance that carries a wave (or disturbance) from one location to another. The wave medium is not the wave itself and it doesn’t make the wave. It just Carries or transports the wave from its source to other locations.
