All objects with a temperature above absolute ZERO emit thermal radiation in a spectrum of wavelengths 5.Surface ocean currents form large circular patterns called gyres in the oceans. These gyres flow clockwise in Northern Hemisphere oceans and counterclockwise in Southern Hemisphere oceans because of the Coriolis Effect. Near the Earth's poles, there is a tendency for the gyres to flow in the opposite direction. please follow me |

* What is double circulation & why isit necessary |
|
Answer» ONG>Answer: Hi good MORNING here is your answer :- Mammals have a double circulatory system. This means that during a single cycle, the blood goes TWICE in the heart. There are TWO loops in which blood is circulated. One loop is OXYGENATED and the other is de-oxygenated. This double circulatory system is necessary because it ensures provision of oxygenated blood to the muscle and not a mixture of oxygenated and de-oxygenated blood. Hence, this system ensures efficient supply of oxygenated blood to the muscles. Explanation: MARK IT BRAINLIEST |
