When a protein is heated beyond its normal temperature range, heat will increase the kinetic energy of atoms in the protein, causing molecular motion that breaks the various bonds that hold the protein in shape. Once the shape is disrupted and the protein cools, various bonds will re-form, b...
In living things, DNA helicase separates two strands of DNA. However, in the laboratory, high amounts of heat are used to separate the strands. Which of the following DNA molecules would require more hear to separate? Why? Sequence X: 5' ATATATGCT...
What happens when the thermal energy of a substance increases? What happens to thermal energy when the number of particles increases? What happens to the atoms and molecules in a substance as its temperature increases? What happens when an amorphous solid is heated? What happens when an interstel...
海洋中珊瑚的美丽颜色来自于其体内与之共生的藻类生物，其中虫黄藻是最重要的一类单细胞海藻。二者各取所需，相互提供食物。全球气候变暖造成的海水升温导致虫黄藻等藻类大量死亡，进而造成珊瑚本身死亡，引发白化现象。然而研究发现，珊瑚能通过选择耐热的其他藻类生物等途径，来应对气候变暖带来的挑战。 以下哪项如果为...
There are two groups of sugars, monosaccharides and disaccharides; longer chains of sugar molecules like starch and cellulose are not considered to be sugars and are usually called polysaccharides. Sugars are used to store chemical energy and are largely produced by plants and then consumed as food...
Chemical reactions involve the interaction of atoms' electron clouds... Learn more about this topic: Basic Properties of Chemical Reactions from Chapter 2/ Lesson 14 71K Chemical reactions, when molecules interact to create new substances, can be written as equations. Learn more about the basic...
Denaturation ("changing the nature") happenswhen protein molecules unravel from their naturally coiled state. With eggs, this happens most frequently when they're heated or beaten, but denaturation can also be prompted by salt, acids (such as vinegar), alkalies (such as baking soda), and free...
the material functions as an insulator; it doesn’t support a sustained flow of charge when an electric field is applied, though it does effectively permit some charge to flow as the field is established due to the shifting of electrons around an atom or reorientation/distortion of molecules. ...
Introduction to Cross Entropy The moment we hear the word Entropy, it reminds me of Thermodynamics. In entropy, the momentum of the molecules is transferred to another molecule, the energy changes from one form to another, entropy increases. Well, what does that mean? There is a disorder in...
The birth of the first stars represents the beginning of a sequence that produced all the worlds and living beings of the universe. Simulations can be used to study the critical first steps that telescopes cannot yet see.
