If a solution process is exothermic, the energy required for dissolving the solute compare with the energy released is that, the energy requiredis less than the energy released. When we sayexothermic, heat is evolved. On the other hand,when heat is absorbed, this is called endothermic.
Answer:
That'll be a "Long term change".
Goodluck with your test! :)
Answer:
B. Base pairing occurs within an RNA molecule to give RNA the three-dimensional shape needed for specific functions.
Explanation:
Ribonucleic acid, known as RNA, is a type of nucleic acid found in living systems. In opposition to the other type of nucleic acid (DNA), RNA is a short single stranded molecule. Both DNA and RNA are made of nucleotides, composed of a phosphate group, nitrogenous bases and a pentose sugar.
The presence of ribose sugar and Uracil base in RNA instead of deoxyribose sugar and thymine base respectively structurally differentiates the molecule from DNA. However, base pairing occurs within the RNA molecule to form the three-dimensional shape of the RNA, which is key to the specificity of its function.
Exploring the city with trolley cars and many hills. This city is San Francisco, CA.
Trolley cars or cable cars were introduced in 1873 to enable locals to contend with many hills the city is built on. Now, tourists ride the cable cars and will be given a tour of the city.
