The skin is richly supplied with arteriovenous anastomoses in which blood flows directly between an artery and a vein, bypassing
yaroslaw [1]

Answer: Temperature control

Explanation:

Arterio-venous anastomoses (AVAs) are direct connections between small arteries and small veins. In humans they are numerous in the glabrous skin of the hands and feet.

They are very significant in body temperature control. These temperature control are under the dual control of the central nervous system and the local thermal influence. While the arteriovenous anastomoses control the skin temperature through volume changes in the superficial venous bed, the arterioles and capillaries operate by generalized dilatation which results both in increased temperature and in redness of the skin.

kolezko [41]

Answer:

Biology can simply be described as the study of living organisms. Biology is divided into many sub categories depending on the features of life that we want to study. For example, molecular biology is the study of molecules which make up living organisms.

Zoology can be described as a branch of biology under which animals are studied. The field of zoology involved studying the taxonomy of animals, their evolutionary histories, physiology, embryology etc. All these studies are  parts of biology hence zoology and biology are related.

What is the major cause of phytoplankton blooms in the Gulf of Mexico?
3241004551 [841]

Answer:

Excessive nutrients from fertilizer run off.  

Explanation:

Scientists have suspected that phytoplankton blooms might be connected to agricultural run-off. They got some evidence from a recent study by comparing the timing of irrigation along the west coast of Mexico and phytoplankton blooms in Mexico’s Sea of Cortez. During the comparison, they had found a close correlation. Phytoplankton blooms occurred in the Sea of Cortez shortly after the irrigation. This happened because of carried fertilizers after irrigation and other agricultural run-offs into the sea.

The bloom detected in the Gulf of Mexico on December 13 might be similarly linked to agricultural run-off.
