What are the 3 major organs of the muscular system? The muscular system is an organ system consisting of skeletal, smooth and cardiac muscles. There are three distinct types of muscles: skeletal muscles, cardiac or heart muscles, and smooth (non-striated) muscles. What are 3 types of muscles? The three main types of muscle include skeletal, […]
How much force is needed to break a wall?
How much force is needed to break a wall? Ever wondered how much force it takes to punch through a sheetrock wall? MissBusters did a study by assuming the distribution was normal. They randomly selected 5 walls and found it took an average of 3.22 Newtons with a standard deviation of 0.81 Newtons to break […]
What percentage of cars are gas powered?
What percentage of cars are gas powered? Most of the motor gasoline sold for use in vehicles in the United States is about 10% fuel ethanol by volume. In 2019, total gasoline consumption accounted for about 58% of total transportation sector energy consumption, 45% of total petroleum consumption, and 17% of total U.S. energy consumption. […]
Does water freeze at high pressure?
Does water freeze at high pressure? At higher pressure, more air (nitrogen and oxygen molecules) goes into solution. The more molecules dissolved in the water, the lower the freezing point. At what pressure will water not freeze? From 0° C at 1 atm pressure it will increase up to 0.01° C at 0.006 atm. This […]
Why would scientists use a control sample that has no DNA?
Why would scientists use a control sample that has no DNA? Scientists would use a control sample that has no dna from bighead carp in edna surveillance in order to to verify that no dna has contaminated the gel. It would eliminate certain errors in the experiment. What eDNA means? gentleness, pleasure, youthfulness. Edna (Hebrew: […]
What are the 5 functions of the female reproductive system?
What are the 5 functions of the female reproductive system? Its functions include producing gametes called eggs, secreting sex hormones (such as estrogen), providing a site for fertilization, gestating a fetus if fertilization occurs, giving birth to a baby, and breastfeeding a baby after birth. The only thing missing is sperm. What is female egg […]
What causes water to dry up?
What causes water to dry up? The main cause for the drying up of the lake is drought caused by climate change impacting the inflow to the lake – resulting in a 65% reduction in water levels. Increased diversion for irrigated agriculture, the building of dams and reduced rainfall over the lake’s surface, are also […]
What are examples of endergonic and exergonic reactions?
What are examples of endergonic and exergonic reactions? Often, one chemical reaction feeds the next and endergonic reactions are coupled to exergonic reactions to give them enough energy to proceed. For example, firefly bioluminescence results from endergonic luminescence by luciferin, coupled with exergonic ATP release. Is Endergonic the same as endothermic? Re: Exothermic vs Exergonic […]
Why can I see my breath in 50 degree weather?
Why can I see my breath in 50 degree weather? The main reason for the breath vapor condensation is the difference in the relative humidity between the exhaled and surrounding air. The three main factors that play into this are temperature, relative humidity, and pressure. You can even see your breath condensate at room temperature […]
Are nuclear power plants economically viable?
Are nuclear power plants economically viable? The study of the economics of nuclear power has found it has never been financially viable, that most plants have been built while heavily subsidised by governments, often motivated by military purposes, and that nuclear power is not a good approach to tackling climate change. Is nuclear power viable? […]
