Hello friend!!
<span>Homeostasis is the process that helps control/maintain the body. The Circulatory System is one of the systems that is in the Homeostasis process. The Circulatory system is the system that is responsible for transporting blood throughout the body.

<span>The Circulatory System transports blood all over the body. The blood flows through the arteries. An artery is a small red tube that is connected to the heart and goes throughout the body. The Circulatory System is divided into 3 major parts the Heart, the Blood, and the Blood Vessels.
</span>
<span>The Circulatory System delivers oxygen and nutrients in the blood to the surrounding cells to maintain Homeostasis. The blood in the Circulatory System is needed throughout the body so that other systems work properly. Like for instance the Nervous System has the brain, and the brain needs blood to function.

<span>The organs in the digestive system need the circulatory system to continue to digest food.It needs the blood that the circulatory
distributes for it's nutrients,as well as to have the nutrients spread,so that the body functions evenly.

Answer:
There is a relationships between the number of stomata and the environment.
Explanation:
The small pores beneath the epidermis of a leaf is the stomata from theis opening gaseous exchange takes place,water evaporates and oxygen goes out. Stomatal density may increase or decrease the response due to environmental variations in the presence of sunlight and water availability. The opening and closing of stomata are controlled by guard cells. Through the stomata the process of transpiration occurs. the roots absorb water and excess of water evaporates by means of stomata.One fact is leaves under sunlight have higher stomatal density than leaves under shade.
