Which type of substance would best dissolve in a solvent that was made of nonpolar molecules.
Studentka2010 [4]
Lthough much of the explanation for why certain substances mix and form solutions and why others do not is beyond the scope of this class, we can get a glimpse at why solutions form by taking a look at the process by which ethanol, C2H5OH, dissolves in water. Ethanol is actually miscible in water, which means that the two liquids can be mixed in any proportion without any limit to their solubility. Much of what we now know about the tendency of particles to become more dispersed can be used to understand this kind of change as well.
Picture a layer of ethanol being carefully added to the top of some water (Figure below). Because the particles of a liquid are moving constantly, some of the ethanol particles at the boundary between the two liquids will immediately move into the water, and some of the water molecules will move into the ethanol. In this process, water-water and ethanol-ethanol attractions are broken and ethanol-water attractions are formed. Because both the ethanol and the water are molecular substances with O−H bonds, the attractions broken between water molecules and the attractions broken between ethanol molecules are hydrogen bonds. The attractions that form between the ethanol and water molecules are also hydrogen bonds (Figure below). There you go

Karo-lina-s [1.5K]

Answer:

option D

Explanation:

Negative feedback is a mechanism in which function of a cell or an organ is decreased. It lessened the output of a system and maintain system function which is known as homeostasis. It is a regulatory mechanism of normal physiology. Some of examples are

blood sugar level regulation, regulation of blood pressure, thermoregulation and many more.

Given the mRNA sequence GGU-GCU-CCU-AUU, what would happen if a nucleotide was added at the fourth location in the chain? A. chr
anygoal [31]

Answer: The correct answer is B) Frameshift mutation.

The given  mRNA sequence is GGU-GCU-CCU-AUU. When a nucleotide is added at the fourth location in the chain, it entirely changes the frame from the insertion of the nucleotide till the end of the gene sequence. This is called a frameshift mutation.

This is because after adding a nucleotide, a new frame is generated that will code for different amino acids and therefore a different protein will be synthesized.

On the contrary, chromosomal mutation is an abnormality in the chromosome ( in terms of number or structure) whereas substitution mutation is the one, which exchanges one base with another. Deletion of base also results in the frame-shift mutation.
