Which level has the most number of organisms but the least specific characteristics?
IgorLugansk [536]

Answer:

Kingdom

Explanation:

Out of all the taxonomic categories, the Kingdom is the least specific, which means it has the least filters.

I like to think of taxonomic categories as filters/sieves. If you put your animals through the Kingdom filter, then all the animals are in that category. if you have a finer sieve, then less animals get through, this goes down all the way to the most specific which is Species.

Hope this helps!

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.
