Answer:

Over 95% of incoming ultraviolet radiation is absorbed in :

A. The Stratosphere.

Explanation:

Stratosphere is the second layer of the earth's atmosphere that lies next to the troposphere.
This layer experiences very little turbulence of air and is very significant because of the presence of Ozone layer in it.
The UV rays entering the Earth's atmosphere, photo dissociates ozone into O₂ and O. But these molecules quickly recombine to form ozone.Thus, stabilizing the concentration of ozone in the atmosphere.
During this photo dissociation UV radiations loses much of its energy. Thus, 95% of incoming Ultraviolet radiation gets absorbed in the Stratosphere.
Absorption of ozone UV radiation increases exponentially with the thickness of ozone layer.

Hydrogen peroxide, fatty acids and ethanol are degraded by this subcellular structure. __________

dangina [55]

Answer: Lysosomes

Explanation:

Lysosomes is the type of organelles which contain enzymes that breaks down the various fatty acids. As, these enzymes basically work in the less oxygen areas and the low PH region. The peroxisomes absorbed all the nutrient from the cell and they are degraded from the sub-cellular structure.

The lysosomes is the single membrane that contain the digestive enzymes for breaking all the toxic material such as fatty acids, ethanol and hydrogen peroxide in cells.

Can someone briefly explain what I need to do to calculate my VO2 max? Thank you

Luba_88 [7]

Answer:Although VO2 max is a good marker of fitness, it does present some downfalls. You can't really get an accurate measure .

Explanation:So, one way to determine your max VO2 pace is to warm up, then run for 8 minutes at the maximum intensity level you can sustain for 8 minutes. If, for simplicity's sake, you ran one mile, then your VO2 max training pace is 8 minutes/mile.

babunello [35]

An ocean current is any more or less permanent or continuous, directed movement of ocean water that flows in one of the Earth's oceans. The currents are generated from the forces acting upon the water like the earth's rotation, the wind, the temperature and salinity differences and the gravitation of the moon.
