Although amphibious frogs live on land and in water, they must lay their eggs in water or the eggs will dry up, effectively killing the offspring inside.<span> Frog eggs are covered with a glycoprotein, which helps keep the eggs moist. This glycoprotein has to keep in contact with a source of moisture, such as water.</span>
Answer:
b. The hydrophobic effect is driven largely by the entropy of the non-polar substance.
Explanation:
The hydrophobic effect is the tendency of nonpolar substances to aggregate when placed in a watery medium. Water has a tendency to form a maximum number of hydrogen bonds with other water molecules or polar substances. When the nonpolar substances are present in water, the water molecule is not able to form the optimum number of hydrogen bonds.
The nonpolar substance orient themselves around the water molecule to allow the formation of hydrogen bonds. This orientation is energetically unfavorable as water molecules are present in a more organized pattern and have lesser entropy that the bulk water. This results in a hydrophobic effect wherein the nonpolar substances exclude water to increase the entropy of water.

The Purpose Cellular Respiration. Cellular respiration is the processby which cells in plants and animals break down sugar and turn it into energy, which is then used to perform work at the cellular level. The purpose of cellular respiration is simple: it provides cells with the energy they need to function. - According to the website I went too. So I'm guessing it's "Produce usable energy - ATP". I hope this helped you! Good luck.
If the isthmus formed gradually rather than suddenly, the morphological species, biological species, and phylogenetic species concepts.
<h3>
What is Isthmus genetical species?</h3>
The formation of the Isthmus of Panama, a slender land bridge that connects North and South America, caused the Pacific and Caribbean populations of marine organisms to split off about 3 million years ago. On both sides of the isthmus, different species of snapping shrimp have been studied. There appeared to be seven pairs of species, with one species of each pair being found in the Pacific and the other in the Caribbean, according to the morphological species concept.
The various species pairs inhabit slightly different ocean depths. These species pairs, which are divided by the isthmus, were indeed the closest relatives of one another, according to the researchers' estimates of phylogenies based on mitochondrial DNA sequences.
