The Correct answer is A.
As snow becomes compressed , air between the flakes gets trapped. The process involving trapping of air occurs during burial of snow layers and is generally not complete until the bubbles are about 60 meters or more below the surface.
Once the bubbles have formed, they act as the time capsules of the atmosphere when they were trapped. By extracting the air from the bubble in ice cores, changes in the past can be studied .
Studies of these changes show the dramatic increase of what are called greenhouse gases such as carbon dioxide, caused by human use of fossil fuels, as well as natural changes that accompany glacial climate
D. All of the above
acid rain damages all of those options
<span>The nervous system that controls respiration is called
autonomic because it isn't subject to voluntary control. Autonomic Nervous
System (ANS) is responsible for regulating the functions of the body's internal
organs like the heart, stomach, and intestines. It is a division of
the peripheral nervous system that acts unconsciously and it regulates
bodily functions like heart rate, digestion, and respiration. The hypothalamus
is the part of the brain that regulates the Autonomic Nervous System. Other
reflex reactions like coughing, sneezing, swallowing, and vomiting are also
part of autonomic functions that occur in the body.</span>
Answer:
Sarah should add 19 grams of protein to her diet if she gets pregnant.
Explanation:
Daily protein requirements = body weight in x conversion factor
Pregnant women= 1.1g/kg prepregnancy body weight
Sarah's prepregnancy weight= 132 pound
Sarah should add about 19 grams of protein to her diet to account for the higher protein requirements of pregnancy. That’s only about 1 cup of Greek yogurt. Pregnancy might be the time to switch to these “twice the protein” products.
Solution:
1. (37 + 12t) - 37 = (85) - 37
2. 12t/12 = 48/12
3. <u>t = 4</u>
