Two identical trays each containing 50 grams of sunflower seeds are placed in a cool dry location. Nothing else is added to the control tray, but the experimental tray receives a mating pair of grain weevils. After 2 weeks, the control tray looks essentially the same, but the experimental tray is now crawling with thousands of weevils actively consuming the seeds. You can see that no weevils have left the tray, and that all of their waste (frass) has fallen in the tray. Based on your understanding of the transformation of energy and matter, which of the following predictions about the relative weights of the two trays is most likely correct? Select one: a. The experimental tray will weigh less than the control tray because the weevils are releasing mass in the form of CO2 gas through cellular respiration b. The control tray will weigh less than the experimental tray because the seeds in it have been undergoing cellular respiration c. The control tray will weigh more than the experimental tray because the uneaten seeds will undergo photosynthesis. d. The experimental tray will weigh more than the control tray because of the added weight of all the weevils
Gene Interactions
When the expression of a single trait is influenced by two or more different non-allelic genes, it is termed as genetic interaction. According to Mendel's law of inheritance, each gene functions in its own way and does not depend on the function of another gene, i.e., a single gene controls each of seven characteristics considered, but the complex contribution of many different genes determine many traits of an organism.
Gene Expression
Gene expression is a process by which the instructions present in deoxyribonucleic acid (DNA) are converted into useful molecules such as proteins, and functional messenger ribonucleic (mRNA) molecules in the case of non-protein-coding genes.
