Introduction: The size and shape of a molecule are unique to their functions. It can be simple as linear shape or complicated. The interaction of an atom or a molecule with the other group drives the rearrangement of the orbital in its valence shell. The pituitary gland is present in the brain, which regulates the endocrine system. It produces a compound called endorphin. Endorphin binds to a receptor present in the brain and relieves pain. Opiates like morphine have a similar shape to endorphin that binds to the receptor. So, it mimics the endorphin and when binds to receptor, it produces similar effects. Female silkworm moths (Bombyx mori) release chemical signals that attract the male moths that are at distant to them. The male moth has a comb-like sensory receptor that binds to a signal molecule that stimulates to fly toward the female moth.
To propose: A hypothesis that how a male moth detects the specific molecule in the presence of other molecules.

- Other than oil and alcohol, are there other liquids you could compare to water (that are liquid at room temperature)? How is water unique compared to these other liquids? What follow-up experiment would you like to do, and how would you relate it to your life?arrow_forwardSelection of Traits What adaptations do scavengers have for locating and feeding on prey? What adaptations do predators have for capturing and consuming prey?arrow_forwardCompetition Between Species What natural processes limit populations from growing too large? What are some resources organisms can compete over in their natural habitat?arrow_forward
- Species Interactions Explain how predators, prey and scavengers interact. Explain whether predators and scavengers are necessary or beneficial for an ecosystem.arrow_forwardmagine that you are conducting research on fruit type and seed dispersal. You submitted a paper to a peer-reviewed journal that addresses the factors that impact fruit type and seed dispersal mechanisms in plants of Central America. The editor of the journal communicates that your paper may be published if you make ‘minor revisions’ to the document. Describe two characteristics that you would expect in seeds that are dispersed by the wind. Contrast this with what you would expect for seeds that are gathered, buried or eaten by animals, and explain why they are different. (Editor’s note: Providing this information in your discussion will help readers to consider the significance of the research).arrow_forwardWhat is the difference between Uniporters, Symporters and Antiporters? Which of these are examples of active transport?arrow_forward
