Answer:

1. Used by Photosynthesis: CO2  Expelled: O2

Used by Cellular respiration: O2 Expelled CO2

2. Most ozone (about 90%) is found in the stratosphere, which begins about 10–16 kilometers (6–10 miles) above Earth's surface and extends up to about 50 kilo- meters (31 miles) altitude. The stratospheric region with the highest ozone concentration is commonly known as the “ozone layer”

3. The surface of the earth heats up

Which of the definitions below best defines a mutation?
victus00 [196]

The correct answer is: A. A change in a cell's genetic material.

Mutations occur in DNA as a result of mistakes during the DNA replication (when repair mechanisms don’t fix it) or as the result of environmental factors (e.g. UV light). Mutations can have positive impact, by increasing the genetic variation or can have negative effect, causing the diseases or cancer.

Most of the oxygen transported by the blood is___________.
Pie

Answer:

c. Bound to hemoglobin.

Explanation:

The oxygen is relatively insoluble in plasma. At normal atmospheric pressure, only 0,3% of oxygen dissolves. That why there are respiratory pigments that <u>elevate almost 70 times</u><u> the capacity to transport O₂ of blood</u>. The most common respiratory pigments are hemoglobin (in all vertebrates and some invertebrates) and hemocyanin (in mollusks and arthropods).
