Answer:
The correct answer is option A, Gastrula
Explanation:
Gastrula has three layers of cell and it is the phase in which single layered blastula matures and get converted into multilayered structure.
However, Morula is formed after the formation of blastula through the process of blastulation. In the Morula phase, blastomers get arranged in a spherical shape after the zygote split. And zygote is formed at a very early stage of fertilization .
Thus , gastrula is the correct answer as it is the stage which comes after zygote and morula and thus get developed into more compact mass of cells.
To make Paramecium Contractile vacuole concentration graph useful the salt concentrations descriptions should replaced with actual values.
Thus, option "A" is correct.
What is Paramecium Contractile vacuole
"It is a sub-cellular structure (organelle) involved in osmoregulation."
<h3>What is a graph?</h3>
"A diagram (such as a series of one or more points, lines, line segments, curves, or areas) that represents the variation of a variable in comparison with that of one or more other variables."
<h3>What does the graph in the given question depict?</h3>
It shows that the Paramecium Contractile Vacuole concentration per minute decreases as salt concentration increases.
But the concentration of salt is not mention in quantity so its not clear what are the lowest and highest concentration affecting Paramecium Contractile Vacuole.
Hence, the Paramecium Contractile Vacuole concentration graph can be more useful if the actual values of salt concentration will be mentioned.

B) 60° north latitude and 0° longitude
Assuming the body weight of the woman is 67 kg, milligrams of digoxin required per day for the woman will be 3.25 milligrams.
<h3>What is drug dosage?</h3>
Drug dosage refers to the amount of drug required to be administered to a patient per given time based on body weight or age.
The dosage for digoxin for treatment of heart failure for the 67 year old woman is 48.5 mcg/kg body weight.
Assuming the body weight of the woman is 67 kg, milligrams of digoxin required per day for the woman will be 48.5 * 67/1000 = 3.25 milligrams.
In conclusion, the dosage of drugs depends on age and body weight.
