This gas causes gas desposition?


answer: conclude, nucleotides are important as they form the building blocks of nucleic acids, such as dna and rna. nucleotides are made up of 3 parts. the first is a distinct nitrogenous base, which is adenine, cytosine, guanine or thymine. in rna, thymine is replaced by uracil.

2.chromosomes                                                                                                                   3.adenine.thymine,guanine,cytosine

4.the nitrogenous bases form hydrogen bonds between opposing dna strands to form the rungs of the "twisted ladder" or double helix of dna or a biological catalyst that is found in the nucleotides. adenine is always paired with thymine, and guanine is always paired with cytosine. these are known as base pairs.

5and 6.adenine are always be an equal number or pair with thymine nucleotides in molecule because of their chemical structure.   yes! guanine are always be an equal number or pair with cytosine nucleotides in molecule because of their chemical structure.

8.the sides of the ladde are made up of alternating sugar and phospate molecules.the steps(rungs)of the ladder are made up of hydrogen bonds held together by hydrogen.


technology and science are related


when you're playing  angry birds  on your smart phone, you likely don't realize how important science is to what you're doing. as the birds catapult through the air, science is probably the last thing on your mind. aside from the physics involved in sending feathered projectiles flying through the air, there's a far deeper connection between science and playing your favorite games. that's because all technology - from smart phones to medical scanners to cars - are intimately connected with science. without science, they wouldn't exist.

science  is the study of the natural world by collecting data through a systematic process called the scientific method. and  technologyis where we apply science to create devices that can solve problems and do tasks. technology is literally the application of science. so, it really is impossible to separate the two. in this lesson, we're going to go into a little bit more detail about how science and technology are related, including some examples.

1. Making dry ice or solid carbon dioxide involves the removal of gaseous carbon dioxide from air and using cold temperatures and higher pressure causes the gas particles to skip the liquid phase and deposit into a solid to form a chunk of dry ice.

2. A carbon dioxide fire extinguisher has been filled with gaseous carbon dioxide but inside the canister the higher pressure causes this to turn into solid carbon dioxide which later is released as a white powder when putting out a fire.

3. In severely cold temperatures frost will form on windows because the water vapor in the air comes into contact with a window and immediately forms ice without ever forming liquid water.

4. Deposition has become a manufacturing technology application where solid alloys are heated to a gaseous state and then sprayed onto things like semiconductors. When the spray is released onto the semiconductor the heat energy is lost and the gaseous substance becomes a solid metal alloy.

5. In geology, deposition refers to a river carrying much sand or silt in its current and as the current slows in certain areas, the sand or silt falls out of the fast moving current and is deposited on the bottom of the river bed.
