Answer:
National Geographic estimates that hair dryers emit, on average, 57 pounds of carbon dioxide (CO2) into the atmosphere every year. That's far less than the average of 727 pounds of CO2 emitted by refrigerators, but this still has a negative environmental impact on our planet.

A wide variety of weather can be found along an occluded front, with thunderstorms possible, but usually their passage is associated with a drying of the air mass. Additionally, cold core funnel clouds<span> are possible if shear is significant along the cold front. Small isolated occluded fronts often remain for a time after a low pressure system has decayed and these create cloudy conditions with patchy rain or showers.</span>
When the continents separated, organisms were forced to be placed in different locations with different environmental conditions. In order to survive in their new environment, over time, various flora and fauna developed various body mechanisms to cope up. This brought up the speciation of flora and fauna.
Answer: Anaerobic, Aerobic
Explanation: Aerobic means with Oxygen,while Anaerobic means without oxygen. Aerobic exercise like running,bike ride,walking increases blood flow. In Aerobic exercise with oxygen,your body produces the muscle need to perform a needed exercise. While in Anaerobic exercise without oxygen means oxygen demand is greater than oxygen supply.
Answer:
The hydrogen bonds of water expand during the freezing process, creating more volume and decreasing density of the ice.
Explanation:
Water has awesome properties that distinguishes it among all other substances, many of which is attributed to its hydrogen bonding. Liquid water contains hydrogen bonds that holds tightly its molecules. However, when this liquid water freezes, the hydrogen bonds between its molecules break and expands. This creates space for the water molecules to occupy as it turns to its solid form (ice).
This is the case of this ice-covered lake. The ice, when it sinks, causes the liquid water beneath to freeze because the hydrogen bonds between the water molecules are being expanded enabling the molecules to occupy more space (volume) and make it less dense than liquid water (decreased density).
