When a salt crystal dissolves in a large glass of water formed the solvent molecules surround the solute ions at the molecular level.
Explanation:
Solvation is defined as the interaction of solute particles to the solvent which stabilises the solute species in solution.
If a crystal of salt is dissolved in water, each of the ions forms of the salt will surround the water molecule. The strong covalent bonds of the water molecule will pull the ions of the crystal salt into the solution. The ions formed will now be surrounded by water molecules which is dipolar. The separated ions get thoroughly mixed in the water.
The pen most likely contains insulin because insulin is a hormone that decreases blood sugar level and is taken in the form of injection by type i diabetic people
Cleaving a flatworm into pieces would not kill the flatworm as each piece would turn into a new flatworm. The mechanism is known as fragmentation. In multicellular species, fragmentation refers to a kind of asexual reproduction in which a species gets cleaved into fragments.
Each of these fragments forms into completely developed, mature individuals, which are similar to their parents. Fragmentation is also called splitting, it is a mode of reproduction witnessed in various species like molds, filamentous cyanobacteria, lichens, various plants, and animals like flatworms, sponges, sea stars, and some annelids.
Answer:
Different
Explanation:
The climatic conditions or weather conditions of the southeast of the United States are different to that of the northeast Africa. And because of this, the two zones are not expected to have the same type of animals.
For example, the weather conditions of the southeast of the United States are humid and thunderstorms, while that of the northeast Africa are hot and dry.
According to the research, the correct option is A, population genetics is the study of how allele frequencies in a population change over time.
<h3>What is population genetics?</h3>
It studies the origin, amount and distribution of genetic variability present in populations.
It explains the variation between individuals, as well as the dynamics of alleles and genotypes within and between populations.
Therefore, we can conclude that according to the research, the correct option is A, population genetics is the study of how allele frequencies in a population change over time.
