Answer:
Your carbon atom enters the leaf as CO2 (carbon dioxide) from the atmosphere. In the leaf, chlorophyll uses the energy from the sun to convert CO2 and H2O to the sugar glucose, C6H12O6. Your carbon atom is part of this molecule; it is now one of the carbons in the glucose.
Next, the glucose carrying your carbon atom is sent down the phloem tissue of the carrot plant to the root, which is the carrot itself. Enzymes in the carrot root connect the glucose molecule with your carbon atom into a chain with other glucose molecules, forming cellulose, or plant starch, and there you go. Your carbon atom went from being part of an atmospheric gas to a starch via photosynthesis and starch formation in the root.
Explanation:
I think the correct answer would be D. The specialized structure that helps a vascular plant to soak up water after a rainfall in a desert would be the extensive shallow root system with root hairs. An example of this would be the cactus. It has a root system that is very different from any plant that is not found in the desert. The roots are found just exactly below the surface. It is ready anytime to suck up water from rain or snowfall and transport it to the stem of the plant. Also, after a rain, the cactus would grow tiny roots in its body to aid in the absorption of water more quickly.

Scientists need to ask those in charge of the green house gas emmision
Explanation:
In this virtual lab, grow two species of paremecium in test tubes and record data on their population growth. Experiment shows that when grown together, one species will die, illustrating the competitive exclusion principle.
Answer:
The brain cells contain DNA molecules, but the skin cells do not.
The skin cells contain DNA molecules, but the brain cells do not.
The brain cells and skin cells both contain DNA molecules, and their DNA molecules contain the same genetic information.
The brain cells and skin cells both contain DNA molecules, but their DNA molecules contain different genetic information.
