The circulatory and respiratory systems work together to circulate blood and oxygen throughout the body. Air moves in and out of the lungs through the trachea, bronchi, and bronchioles. Blood moves in and out of the lungs through the pulmonary arteries and veins that connect to the heart.
Answer:
Being endothermic
Explanation:
Humans are not cold-blooded and we don't photosynthesise so only the second option applies to humans;
We produce heat internally within our bodies so we are endotherms, i.e. warm-blooded;
We shiver and have thermogenesis through metabolism to generate heat to keep body temp up and also sweating and physiological mechanisms to cool out bodies down.
Hornblende and other amphiboles have double chain silicate structures.
Tetrahedron (SiO4)^4- is the fundamental building block of all the silicate minerals. Silicate minerals comprising chains are known as inosilicates. In single chains, the ratio of silicon to oxygen is 1: 3, while it is 4: 11 in the case of double chains.
The double-chain silicates take place when tetrahedral produce a double chain by sharing two or three oxygen atoms each.
