Answer:
B. both water and calcite contain oxygen.
Explanation:
water molecules are not equal some are substituted with a heavier counterpart,the standard Oxygen molecule can be substituted by the 18O and hydrogen by H2 given rise to H216O,HD16O and H118O they are termed isotopologues and gave different physical properties.First, over the ocean, the heavier isotopes are less likely to take part in the formation of moisture, leading to lower concentrations of the heavy isotopes in the clouds compared to the mean oceanic water isotopic composition (lower concentration means that the δ18O is more negative). Then, as the air masses move toward the poles, temperature decreases leading to precipitation (either liquid or solid). The heavier isotopes will be preferentially found in the condensed phase than the light ones, which depletes even more the cloud from its heavy isotopes. Finally, in remote areas of the Polar Regions, the isotopic content of the final precipitation results from successive precipitation events. Since, as we saw, the precipitation contents in each isotope are different, each successive precipitation event will have a different isotopic composition, with the final one having the least heavy isotopes – a process called distillation. At each step of the moisture’s path from ocean to cloud to precipitation, the isotopic fractionation is strongly influenced by temperature. This leads to a temperature signal in the isotopic composition of both vapour and precipitation
The population decays by a factor of (1/2 )^1/4 every hour.
<h3>
Exponential Function</h3>
An exponential function is in the form:
y = abˣ
Where a is the initial value of y, b is the multiplier, y and x are variables.
Let y represent the bacteria population after x hours.
A bacteria population decreases by a factor of 1/2 every 4 hours.
The population decays by a factor of (1/2 )^1/4 every hour.

Answer:
True
Explanation:
According to ILO (International Labour Organization), it has been observed and found TRUE that Migrant workers who fill employment needs in their host country often send remittances to their home countries.
While the migrants contribute to the economy of the host country through their remittance, work done, and skill, they usually send extra remittances to their home countries, usually to cater for families left behind or to go back to their home country.
17-1800's
I know that James Hutton is considered a father of modern geology and he was born during some where in the 1720's so that's the closest answer, also Charles Lydel was born during the late 1790's.
