What are the 3 stages of cell signaling? The three stages of cell communication (reception, transduction, and response) and how changes couls alter cellular responses. How a receptor protein recognizes signal molecules and starts transduction. What are the 3 types of cell communication? There are three different types of basic cell communication: surface membrane to […]
What is an example of a directional hypothesis?
What is an example of a directional hypothesis? Directional hypothesis: A directional (or one tailed hypothesis) states which way you think the results are going to go, for example in an experimental study we might say…”Participants who have been deprived of sleep for 24 hours will have more cold symptoms in the following week after […]
How did Dmitri Mendeleev impact the world?
How did Dmitri Mendeleev impact the world? Lived 1834 – 1907. Mendeleev’s wish led to his discovery of the periodic law and his creation of the periodic table – one of the most iconic symbols in science: almost everyone recognizes it instantly: science has few other creations as well-known as the periodic table. Can you […]
When a substance is boiling Will the added heat increase its temperature?
When a substance is boiling Will the added heat increase its temperature? Adding heat, however, does not always increase the temperature. For instance, when water is boiling, adding heat does not increase its temperature. This happens at the boiling temperature of every substance that can vaporize. What are the 4 conditions which allow bacteria to […]
What are the 6 stages of the design process?
What are the 6 stages of the design process? Designers tend to use a six-stage process to organize their fact finding and decision making: (1) Empathy, (2) Define, (3) Ideate, (4) Prototype, (5) Test, and (6) Launch. Note, user refers to anyone who is a target of our design work. Empathy: Empathy is the foundation […]
How does a ionic bond form?
How does a ionic bond form? An ionic bond is formed by the complete transfer of some electrons from one atom to another. The atom losing one or more electrons becomes a cation—a positively charged ion. The atom gaining one or more electron becomes an anion—a negatively charged ion. What must occur for an ionic […]
Why different objects kept on a table at room temperature do not exchange heat with table?
Why different objects kept on a table at room temperature do not exchange heat with table? Answer. Answer: The sense of touch allows us to recognise temperature differences of objects in the same room which we could easily assume should all be at that same room temperature. The temperature of an object is dependant on […]
What are the 3 electron carriers?
What are the 3 electron carriers? Oxidation-reduction reactions always happen in matched pairs; no molecule can be oxidized unless another is reduced. Flavin Adenine Dinucleotide. Flavin adenine dinucleotide, or FAD, consists of riboflavin attached to an adenosine diphosphate molecule. Nicotinamide Adenine Dinucleotide. Coenzyme Q. Cytochrome C. Is NADH an electron carrier? NADH is the reduced […]
