How much light is there in the universe? According to calculations, the current comoving distance—proper distance, which takes into account that the universe has expanded since the light was emitted—to particles from which the cosmic microwave background radiation (CMBR) was emitted, which represents the radius of the visible universe, is about 14.0 billion … How […]
What is the function of the electron transport chain of photosystem II?
What is the function of the electron transport chain of photosystem II? The electron transport chain helps to move electrons from PS 2 to PS 1. It makes oxidation-reduction reactions within the photosystems. It also uses energy to bring in hydrogren molecules to make a concentration gradient in the thylakoid compartment, which eventually creates ATP […]
Does horsepower determine top speed?
Does horsepower determine top speed? Acceleration time and speed are closely related to horsepower. In general the more horsepower a car has the higher its top speed is, and the faster it can accelerate to 60 mph. How fast is 175 horsepower? We see most 150 engines today on current rigs capable of a run […]
Can quasars destroy galaxies?
Can quasars destroy galaxies? However, a series of new papers suggests, the very same radiation that puts quasars on our maps of the universe may be devastating the galaxies that host the insatiable objects. What is the hardest metal on earth? tungsten What is the softest rock in the world? talc What’s the hardest stone […]
Does the RBE stay constant for different ISO effects?
Does the RBE stay constant for different ISO effects? It follows that RBE cannot be a constant value when taken in the context of the complexities of different tissues within the human body, the heterogeneity of cancer types, and the wide variety of doses used as well as the degree to which Bragg peaks are […]
What is the lowest lying country on Earth?
What is the lowest lying country on Earth? The Netherlands How high will the oceans rise by 2050? In 2019, a study projected that in low emission scenario, sea level will rise 30 centimeters by 2050 and 69 centimetres by 2100, relative to the level in 2000. In high emission scenario, it will be 34 […]
How does culture affect health?
How does culture affect health? Culture influences healthcare at all levels, including communications and interactions with doctors and nurses, health disparities, health care outcomes, and even the illness experience itself. People in some cultures believe illness is the will of a higher power, and may be more reluctant to receive health care. How does culture […]
Can we mix gas and liquid?
Can we mix gas and liquid? You can mix solids with solids, solids with liquids, and liquids with liquids. You can mix gases with gases, and liquid with gases. These combinations of materials are called mixtures. Sometimes it is easy to see the different materials in a mixture. Can a gas mix into a liquid? […]
What operates best under bright light conditions?
What operates best under bright light conditions? The fovea contains cones that possess high levels of visual acuity and operate best in bright light conditions. What is the process of receiving stimulus energies? The process of receiving stimulus energies from the external environment and transforming those energies into neural energy is called SENSATION. The process […]
What is the source of energy for regenerating ATP from ADP?
What is the source of energy for regenerating ATP from ADP? Energy derived from glucose catabolism is used to convert ADP into ATP. When ATP is used in a reaction, the third phosphate is temporarily attached to a substrate in a process called phosphorylation. What happens when ADP is converted to ATP? When one phosphate […]
