Answer: Natural Selection
Explanation:
Atrial natriuretic peptide released by certain atrial cells
in response to rising BP or volume, causes systemic vasodilation and inhibits
renin, aldosterone, and ADH release. Hence, it enhances Na+ and water
excretion, reducing BP and bv. Falling
arterial pressure promotes vasoconstriction and conserves Na+ and water.
Answer
Hi,
They are spread primarily by human activities.
Three methods that can spread invasive species is ; blowing by wind, splashed by rain and carried by animals.
Explanation
Invasive species are a kind of living organisms that are new to an ecosystem and can result into harm that is diverse .These species grow and reproduce at a quicker rate and spread rapidly with potential of causing more harm. In short distances, these organisms depend on natural dispersal ways to spread to other places. Example of an invasive species is Burmese pythons in the Everglades.
Hope this helps!
A tolerance curve is the range of conditions which show how
an organism can live and function. It is a graph that will show the organism’s
activity in certain environmental conditions. There are different species all
over the world and each of them has certain environmental conditions which it
can best survive and reproduce. These are the conditions which the species has
best adapted. These conditions may include physical factors in the area such as
temperature, humidity, soil chemistry, pH, salinity and oxygen levels.
