The labelled cell organelle is Mitochondria.
(B) Cellular Respiration
Answer:
Explanation:
Artic Ice are melting due to change in the climatic system as a result of global warming. The active increase in human activity resulting in global warming will continually perpetuate the decrease in artic Ice.
Artic heat help to balance temperature or heat on the earth surface by reflecting heat back into the environment. When the artic Ice is reduced, the amount of heat reflected is also reduces.
Coastal community - a continuous rise in ocean level can lead to flooding which will affect the coastal community surrounding the ocean. An the ocean has been incredible gradually over the pass decades.
Food - Reduction in the artic Ice car Lea to increase heat affect crop growth through damage by heat stresses leading to an increase price rate of food.
Meltng of Ice increase the shipping routes causing more harm through ship wrek.
Melting of Ice can leave to loss of animals that depends on it for survival.
Permafrost occurs when the ground is permanently block or frozen leading to accumulation of methane gases that causes global warming.
