Answer:
B They go through many developmental changes.
Explanation:
According to the passage, development of frogs are susceptible to minor environmental changes due to the series of developmental changes they undergo.
During the developmental phase of a typical frog, several complicated cellular differentiation cycles occurs. These cycles are connected to one another and they are triggered by certain signals and responses. Disruption in certain environmental factors can affect the various developmental changes.
The answer to this would be false.
An ion with fewer electrons than its neutral atom is called a(n) cation. The charge of an ion with more electrons than its neutral atom is. negative.
This problem is providing us with the percent composition of a compound containing magnesium, nitrogen, oxygen and water. Thus, the empirical formula is required and found to be Mg(NO₃)₂·6H₂O.
<h3>Empirical formulas</h3>
In chemistry, empirical formulas are used in order to figure out the minimum whole-number representation of a molecular formula, which contains the actual number of atoms.
Thus, we start determining it by assuming the given percentages as masses and calculating the moles with the atomic or molar mass of the involved species:
Next, we divide by the 0.386 as the smallest number of moles in order to determine their subscripts in the chemical formula:
Hence, the empirical formula turns out to be Mg(NO₃)₂·6H₂O, which is actually a hydrate (hexahydrate).
