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 […]
What are the giant covalent structures?
What are the giant covalent structures? A giant covalent structure is a three-dimensional structure of atoms that are joined by covalent bonds. Allotropes are different forms of the same element, in the same state. Graphite ,graphene and diamond are allotropes of the same element (carbon) in the same state (solid). Carbon can form up to […]
Which of the following is the same for all three isotopes of hydrogen?
Which of the following is the same for all three isotopes of hydrogen? Hydrogen and its two naturally occurring isotopes, deuterium and tritium. All three have the same number of protons (labeled p+) but different numbers of neutrons (labeled n). How do atoms of same element differ? Atoms of the same element can differ in […]
How long was the lifespan of a dinosaur?
How long was the lifespan of a dinosaur? Early estimates of 300-year lifespans for the largest sauropods were based on comparisons with crocodiles and turtles, which have much slower metabolisms. The consensus is now that Apatosaurus and Diplodocus dinosaurs probably only lived for 70 or 80 years, which is about the same as an elephant […]
When should I remove silt fence?
When should I remove silt fence? Removal – Silt fences shall be removed once the disturbed area is permanently stabilized and no longer susceptible to erosion. for more information. F. To protect silt fence from damage in areas of active construction or heavy traffic, silt fence should be flagged, marked, or highlighted to improve visibility. […]
Is clockwise work positive or negative?
Is clockwise work positive or negative? In cyclic process, work done is equal to the area of closed curve. It is positive if the cycle is clockwise and it is negative if the cycle is anticlockwise. Where did the term clockwise come from? An old Scottish word that is still used is “widdershins”, meaning “against […]
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 […]
Do microwaves only heat up water?
Do microwaves only heat up water? In summary: microwave ovens only really heat water (well), so yes they only heat the water in food; however, it doesn’t have to be liquid, it just absorbs more of the microwaves actually produced, causing liquid water to heat much more rapidly. Further more: yes absolutely your hand would […]
Does gravity affect aging?
Does gravity affect aging? There is no correlation between Gravity and aging. Aging is a process that is independent of Gravity. Gravity is a property of matter. Has more to do with atmospheric pressure than the effects of Gravity. Is gravity necessary for life? Gravity is very important to us. We could not live on […]
