How is Crispr done? The CRISPR-Cas9 system works similarly in the lab. Researchers create a small piece of RNA with a short “guide” sequence that attaches (binds) to a specific target sequence of DNA in a genome. The RNA also binds to the Cas9 enzyme. Why is Crispr so useful? CRISPR is an acronym for […]
How does temperature increase reaction rate?
How does temperature increase reaction rate? An increase in temperature typically increases the rate of reaction. An increase in temperature will raise the average kinetic energy of the reactant molecules. Therefore, a greater proportion of molecules will have the minimum energy necessary for an effective collision (Figure. Why are some reaction very fast? Reactions in […]
How do deep sea creatures get oxygen?
How do deep sea creatures get oxygen? In general, fishes breathe by absorbing dissolved oxygen through their gills; however, in the bathypelagic (or midnight) zone of the ocean, there is zero light, high pressure, low temperature, low nutrients and low dissolved oxygen content. In order to preserve energy, many fishes in this zone have a […]
Is ATP synthase part of the electron transport chain?
Is ATP synthase part of the electron transport chain? ATP synthase is considered a part of the electron transport chain, but it is not involved in the transport of electrons. ATP synthase uses the proton gradient created by the ETC to synthesize ATP. Where does synthesis of ATP occur? Most of the ATP in cells […]
What is the result of vector A B AB?
How can we maintain our internal environment?
How can we maintain our internal environment? Homeostasis is the maintenance of a stable internal environment. Homeostasis is a term coined to describe the physical and chemical parameters that an organism must maintain to allow proper functioning of its component cells, tissues, organs, and organ systems. What are three examples of stimulus and response? Examples […]
What is the relationship between the four spheres of the earth?
What is the relationship between the four spheres of the earth? These spheres are closely connected. For example, many birds (biosphere) fly through the air (atmosphere), while water (hydrosphere) often flows through the soil (lithosphere). In fact, the spheres are so closely connected that a change in one sphere often results in a change in […]
Which enzyme is responsible for adding complementary DNA?
Which enzyme is responsible for adding complementary DNA? DNA polymerase How do phosphodiester bonds form in DNA? In DNA and RNA, the phosphodiester bond is the linkage between the 3′ carbon atom of one sugar molecule and the 5′ carbon atom of another, deoxyribose in DNA and ribose in RNA. When a single phosphate or […]
Which is an example of density-independent factor?
Which is an example of density-independent factor? For example, for most organisms that breathe oxygen, oxygen availability is a density-independent factor; if oxygen concentrations decline or breathable oxygen is suddenly made unavailable, such as when oxygen-using plants are covered by rising floodwaters, those organisms perish and populations of the various affected … What do all […]
