Warm and rainy, It is a warm front, a warm front is a low-pressure system, which means that it will be rainy.
Explanation:
Single circulation is less efficient as gill capillaries slow down the blood flow so the body receives blood at a low pressure which decreases the oxygen supply to the cells.
Double circulation is more efficient as blood at higher pressure especially in humans and mammals
In single circulation only venous blood passes through the heart.
In double circulation mixed or oxygenated or venous blood passes through the heart.
<span>Infiltration is the process by which rain water becomes
ground water. The rainwater that falls on the surface of the earth or soil
slowly gets absorbed by the soil. This process is called infiltration. The water
from outside is infiltrating the ground and mixing with the water that is already
present under the ground. It helps to soften and moist the soil of the earth
very quickly and the farmers take the advantage of sowing seeds of variety of
plants. </span>
