Answer: 400 Micro-grams
Explanation:
The institute of the medicine, suggest all the women who are pregnant should consume atleast 400 micro-gram per day. In year 1998, this institute take the responsibility to recommend all the pregnant women about their diet plans.
They recommended to take 40 micro gram per day of the synthetic folic from the supplements and fortified food. The folic acid is the type of synthetic vitamin B. The women should consume the food from, the varied diets as it helps to prevent the brain of the baby and also from birth defects.
You WILL lose thermal energy cuz heat will always flow from warmer to cooler.
Hope it helps!
B. Ice-albedo feedback
Explanation:
The ice-albedo feedback is one process that can significantly increase the rate of greenhouse emissions in response to a decreased albedo.
Albedo is the ratio of reflected light to incident light.
A decrease in albedo suggests that a surface is absorbing more light than it is reflecting. This is typical of areas with land cover and vegetation.
Areas with a high reflectivity have a high albedo. Snow, ice and polar regions are good reflectors of solar radiation. They have a very high albedo close to 100%. Much of the surface area is buried with ice.
Examples of greenhouse gases are carbon dioxide, methane, water vapor e.t.c
How does a low albedo relates to increase in greenhouse gas emission?
- The ice-albedo feedback can substantially contribute to greenhouse gas emission.
- The high reflectivity of ice causes long wave radiation to warm the air around a icy body in polar regions.
- When ice melts, they leave land bare and exposed.
- Melt water collects in pockets.
- Exposed land leads to a decrease in albedo.
- Organisms can thrive more in warm terrain.
- Also, pockets of carbon dioxide gases trapped in ice is released.
- Organisms release carbon dioxide into the atmosphere during cellular respiration.
- Soils originally permafrost will become stable and this will encourage more human occupation of the area.
- All these activities leads to an increase in the emission of greenhouse gases in an area with low albedo.
