Answer:
Population is defined as a group of organisms, which belong to the same species. Example- Human population includes a group of organisms that all belong to the species sapiens
Explanation:
Limiting factors control the size and growth of an organism’s population.
We need to show that y = x/(x + c) is a solution of dy/dx = (y - y^2)/x. Then,
<span>dy/dx = ((x + c) * 1 - x * 1)/(x + c)^2 </span>
<span>= (x + c - x)/(x + c)^2 </span>
<span>= c/(x + c)^2 </span>
<span>and </span>
<span>(y - y^2)/x = (x/(x + c) - x^2/(x + c)^2)/x </span>
<span>= (x(x + c) - x^2)/(x(x + c)^2) </span>
<span>= (x^2 + cx - x^2)/(x(x + c)^2) </span>
<span>= cx/(x(x + c)^2) </span>
<span>= c/(x + c)^2 </span>
<span>which proves the equality. </span>
Answer:
A
Explanation:
The earth is tilted at an average of 23.5 degrees. This means that in some seasons, the north pole is tilted towards the sun and in some seasons it is tilted away from the sun. The sun seems to vary in position over an year as the earth revolves around the star. The sun, therefore, variably and differentially heats the regions of the earth. The regions that are heated more form low-pressure system that drives winds.
Answer:
Blood leaves the heart through the pulmonic valve, into the pulmonary artery, and to the lungs. Blood leaves the heart through the aortic valve, into the aorta, and to the body. This pattern is repeated, causing blood to flow continuously to the heart, lungs, and body.
