The observation, identification, description, experimental investigation, and theoretical explanation of phenomena is all part of science. Nothing is immune to the scientific process: from charm quarks that haven't existed naturally since the beginning of time to Pluto, recently demoted from planet to dwarf planet. Questions on knowledge about the material and physical aspects of our world are asked and answered here.

Asked in Science, Atomic Mass


What is gold's mass number?

   User Avatar 
   The only stable, and only naturally-occurring isotope of gold has mass number of 197. This is the number of protons and neutrons in each nucleus. Gold's atomic number is 79. This is the number of protons found in each gold atom. This determines its place in the periodic table, and its chemical properties: it is the defining property of gold. A nucleus with a different number of neutrons and the same 79 protons would be a different isotope with a different mass number; a nucleus with a different number of protons would not be gold, but some other element.

   User Avatar 
   Yes The independent variable is also known as the manipulated variable. In an experiment where you need to test different objects, the independent variable would be the different objects.

Asked in Science, Urinary System


What are the tubes called that carry urine away from the kidneys to the urinary bladder?

   User Avatar 
   As I believe has already been stated the Ureters, which are also the source of blockages from kidney stones. Not where they come from that is but where stones large enough usually 5 mm can cause blockages. 2 and 3 even 4 mm stones csn take up to 45 days to pass but usually do. The danger is if stones are present in both Ureters and are causing blockages then the urine can back up and seep into your abdomen and cause infection throughout, this is called sepsis and is life threatening which can kill you in a matter of hours. They usually implant a stint bypassing the Ureter to avoid such an incident, the good news is your body was designed with redundancies. You only need 1/3 of 1 kidney to sustain bodily function.

What is the process that powers plate tectonics?

   User Avatar 
   Convection, as heat from the mantle is transferred to the lower crust, which can move very slowly in response to the increased upward pressure. The heat makes the rock liquid (magma) in some areas, allowing it to flow upward to the surface, thus creating spongebob squarepants!

Asked by Karley Harber in Earth Sciences, Science


If we can't tunnel through the Earth, how do we know what's at its center?

   User Avatar 
   First, scientists are pretty sure the Earth's core is about 80 percent iron. How they know that is a series of educated guesses. For starters, they can be reasonably sure of the planet's mass based on its gravitational pull. The material on the surface isn't dense enough to match up with that mass, so the rest of the Earth has to be much denser. Iron, meanwhile, is one of the most prevalent elements in the universe, but it isn't all that evident in the Earth's crust. Since scientists would expect more iron to be in our planet and it's a fairly dense element, that leads to the conclusion that the Earth's core is mostly iron. They theorize that it was pulled to the core over millions of years. By examining different seismic waves, they know that the inner part of the core is solid and the outer core is molten. It's a lot more scientific than I've made it sound, but hopefully that gets at the gist of it.

Asked in Science, Ingredient Substitutions, Baking Soda (sodium bicarbonate)


What is an alternative to bicarbonate soda?

   User Avatar 
   Depends on what reciepe you are using and what the purpose is: I often use yeast but in some recipes depending on the fluffiness of the cake I will sometimes use baking soda. A friend of mine uses "fizzy water" (carbonated water) as an alternative. Yeast is only used in bread related recipes, whereas bicarb can be used n cakes ~ Baking Soda in a recipe is to help with 'spreadability of the cookie or cake. You don't use it in pancakes so you want the batter to 'stay put'. In a cookie, you want it to spread out a bit, in the cake, you want it to fill in the space of the pan. Baking Soda and Baking Powder CAN be used for each other in a subbing situation. They are both considered leavening agents. In choosing to substitute one for the other you have to know the ratio AND the fact the flavor WILL be DIFFERENT. 1 TSP of Baking Soda needs 3 TSP of Baking Powder. OMIT all SALT. Reverse it to use soda instead of baking powder. You can also use 2 tsp soda and 1 tsp cream of tarter to create BAKING
   POWDER. Again, omit the salt from the recipe. AGAIN, any substitutions of ingredients, expect flavor change to happen.
