Vadim26 [7]

Answer;

-Bone tissue becoming stronger.

The mechanical stress applied to bones during moderate physical exercise leads to bone tissue becoming stronger.

Explanation;

-Bones and muscles both become stronger when muscles push and tug against bones during physical activity.Swimming and bicycling are not weight-bearing activities, so they do not directly help build bones. But swimming and bicycling do help build strong muscles, and having strong muscles helps build strong bones.

-Weight-bearing physical activity causes new bone tissue to form, and this makes bones stronger. This kind of physical activity also makes muscles stronger. Bones and muscles both become stronger when muscles push and tug against bones during physical activity.

Then
1000 (2)^t = 50000
2 ^t = 50
t = 5.6

I hope the procedure is clear enough for you to understand.

Which kind of organism does not generally require oxygen or sunlight to live?
gregori [183]
Answer is A.

Archaea requires neither sunlight for photosynthesis as do plants, nor oxygen. Archaea absorbs CO2, N2, or H2S and gives off methane gas as a waste product the same way humans breathe in oxygen and breathe out carbon dioxide. An example is chemosynthetic bacteria by sea drifts. They use chemical energy to produce vital processes to live.
