Explain how a carbon atom in a CO2 molecule in the air can become part of a cellulose molecule in a plant
Kay [80]
Your carbon atom enters the leaf as CO2 (carbon dioxide) from the atmosphere. <span>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. </span>
<span>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. </span><span>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. </span>

Distinguish between directional, stabilizing, and disruptive selection. Give examples.
Pepsi [2]
Distribution of phenotypes within a population may be impacted by different types of natural selection. These types of selection include;
Directional selection involves a change in the environment shifts of phenotypes observed. Example is the giraffe neck-length, where the length got longer and longer over time to reach the leaves at the top of trees.
Stabilizing selection , this is a selection where an average phenotype is favored. example is number of eggs laid by birds such that too many eggs will be a waste of energy because some chicks would starve.
Disruptive selection is a selection where individuals with an average value of a trait are affected most while those with values below average are affected least. Example small individuals are capable of hiding from predators while big individuals can not fit in the hiding place but instead will fight with predators.
