The vast majority of a tree's carbon comes from the air, which averages 0.03-0.04% by volume (300-400 ppmv) CO2. This is fixed through photosynthesis and eventually stored as glucose which the plant can then use for its metabolism.
Answer:
This is a slightly vague question because there are many reasons why DNA can be damaged and determining which organelle was at fault is generally a case by case matter. but the only part of a cell that you could considered to be tasked with protecting genetic material is the nuclear envelope which is simply a phospholipid bilayer surrounding the nucleus and/or the nucleolus so I would say the answer is the nuclear membrane and/or nuclear envelope.
The organelle you're looking for should be cholorplasts.
Chloroplasts are double membrane bound organelles, which is important for the process so photosynthesis. The outer membrane is smooth and gives the shape of the chloroplast, while the inner membrane forms sac that contains chlorophyll inside.
Chloroplasts exists in green plants that photosynthesize for energy, and they appear the most in mesohpyll cells, a type of cells in leaf.
Answer;
D) the dollar to appreciate when compared to the Euro.
Explanation;
-Changes in exchange rates cause a change in the international relative prices of goods. One country's goods and services become more or less expensive relative to another's.
-Additionally; changes in exchange rates can cause a change in the international relative prices of assets. These fluctuations in wealth can then affect firms, governments, and individuals.
-An exchange rate crisis occurs when a currency experiences a sudden and large loss of value against another currency following a period in which the exchange rate had been fixed or relatively stable.
