1. How is pressure related to force and surface area?
ki77a [65]
Air pressure pushes all around you, it is the force of air spread over the surface area of your skin


pressure is the measure of how much force over a certain area

this is an example
imagine putting a 10 pound weight (disk) on your stomach (not dropping, puttting), not too hard right, now imagine that it was 1 pin that was 10 pounds, that would hurt, the force is still 10 pounds down but the surface area is alot smaller, more pressure

Compare rates of succession: primary succession such as on new lava flow vs secondary succession in a forest that recently burne
Serggg [28]

Answer:

The answer is option D "Succession rates would depend on the number of early arriving facilitator species"

Explanation:

Ecologists have a solid interest in knowing how communities structure and change over the long run. Indeed, they have invested a ton of energy seeing how complex communities, such as forests, emerge from void land or uncovered stone. They study, for instance, locales where volcanic eruptions, ice sheet retreats, or out of control fires have occurred, clearing land or uncovering rock.

In examining these destinations over the long haul, ecologists have seen steady cycles of progress in natural communities. As a rule, a community emerging in an upset territory experiences a succession of movements in synthesis, frequently throughout numerous years. This arrangement of changes is called natural succession.

Succession is a progression of reformist changes in the structure of an ecological community over the long run.

In primary succession, recently uncovered or recently shaped stone is colonized by living things unexpectedly.

In secondary succession, a territory recently involved by living things is upset then recolonized following the aggravation.

what is the process by which substances move across the membrane through channels without using energy
dem82 [27]

Because facilitated diffusion is a passive process, it does not require energy expenditure by the cell. Water also can move freely across the cell membrane of all cells, either through protein channels or by slipping between the lipid tails of the membrane itself.




hope this is the right answer......
