Blood circulation in a mammal is said to be double because

It passes twice through the heart in a complete circuit

It moves in both arteries and veins

It circulates in both the hands and other organs

The heart contains auricles and ventricles

The reason why the flow of blood through the capillaries is very slow is

to allow adequate time for exchange of materials

because the walls of Capillaries are very thin

Xylem

Cortex

Phloem

Cambium

Answer Details

The plant tissue that carries water and mineral salts from the roots to other parts of the plant is called xylem. Xylem is like a pipeline that runs throughout the plant and is responsible for transporting water and dissolved nutrients from the roots to the leaves and other parts of the plant. This tissue is made up of specialized cells called tracheids and vessel elements that are arranged end to end to form long, hollow tubes. These tubes allow water to flow through them with minimal resistance, and the water is pulled up through the xylem by a process called transpiration. In summary, xylem is the tissue responsible for carrying water and mineral salts from the roots to the rest of the plant, and it does so through a network of specialized cells that form long, hollow tubes.
