Answer:
- fresh snow → 0.9
- soil → 0.2
- ocean (high-angle sun) → 0.05
- ocean (low-angle sun → 0.95
Explanation:
Albedo is the radiation reflected by the earth´s surface to the universe.
Albedo might be defined as a relation between reflected light from a particle and the incident light. It is the fraction of the incident radiation that is reflected by any object. If the surface is mostly clear and clean, most of the incident radiation is reflected. But if the surface is dark and rugose, most of the incident radiation is absorbed, and the temperature of the absorbing object will increase.
Albedo value is always inferior or equal to one and can be expressed as a percentage. The surface that reflects 100% of the incident light will have an albedo value = 1. But if the surface absorbs all the radiation and does not reflect any percentage, the albedo value = 0. Note: there is no real object that might reflect or absorb 100% of the incident radiation.
The importance of albedo is that it avoids high temperatures on the earth. There are many different surfaces with different albedo values. Global variations in albedo are natural processes due to exogenic and endogenic variations. But to these natural events, we must add all the variations caused by human beings´ actions, which increase greenhouse gases, decreasing albedo, and increasing global warming. The increase of greenhouse gases, such as CO₂, decreases albedo. The same occurs with atmospheric dust due to volcanic eruptions. Additional material interposes between the earth´s surface and the universe, decreasing the energy return to the universe.

Answer:
. Identify the process that triggers the initial surge of nitrogen excretion,
The reason for this is because of the gluconeogenesis ,(in the liver and cortex of the kidney) which make up for the reduction in glucose blood level, from rapid catabolism to glucose at the beginning of fasting, by breaking down protein to glucose in the liver. Therefore excess Nitrogen is produced as the byproducts of amino acids catabolism.
Physiologically the mammalian brain prefers the keto bodies supply from fatty acids catabolism from gluconeogenesis compare to protein. These water solube subtances cross the BBB to reach the brain the CNS substituting for glucose. Thus as more fatty acids is converted to ketobodies at faster rate, the brain gets adapted to this, and therefore catabolism of amino acids drops, hence Nitrogen concentration in the blood drops.
However, with exhaustion of Glycogen and fatty acid, catabolims of amino acids resumes. therefore, more amino acids are broken down, and Nitrogen build up in the Urine for excretion.
Explanation:
I believe the correct answer is - <span>This drug helps people lose more weight than diet and exercise alone.
It says here in the text - 48% of the people who took these drugs along with exercise and diet lost weight, whereas only 23% of those who had exercise and diet (but no drug) lost weight. Obviously, this shows that more people who took the drug lost weight than those who didn't.

<span>The simplest, yet most effective method of preventing the spread of an infectious disease is to </span>wash your hands in between patient contacts.
Washing hands regularly in the right moment will cause the pathogen harder to spread, thus making it less likely to infect other people.
