The graphs below show the change in temperature and salinity of a region of ocean as a instrument is lowered below the surface. Depth is measured in kilometers below the surface, temperature in degree Celsius, and salinity in parts per thousand.
Which prediction is most likely, based on the data?
Answers:
A) In the ocean, as salinity increases, temperature increases.
B) Organisms that require a steady salinity move freely between sea level and -0.4 km.
C) Ocean salinity decreases at depths greater than -1.8 km below the surface.
D) Organisms that require a temperature at 5 degrees C will thrive -0.6 km below the surface.
The most likely prediction based on the data is 'organisms that require a steady salinity move freely between sea level and -0.4 km' (Option B).
Salinity conditions refer to the concentration of dissolved salts in an aqueous medium.Salinity conditions may alter the physiological features of an organism, as well as its metabolic pathways (e.g., behavior, reproduction, motion).The changes in salinity can negatively alter the evolutionary fitness of an organism and its survival in particular environmental conditions (in this case, steady salinity allows organisms to move freely).In conclusion, the most likely prediction based on the data is 'organisms that require a steady salinity move freely between sea level and -0.4 km' (Option B).

Which coefficient is needed in front of NaNO3 to balance the equation Na2S + Zn(NO3)2 – ZnS + _NaNO3?
O 1
O 2
O 5
O 7
Answer:
A.1
Explanation:
The coefficient needed in front of NaNO₃ to balance the equation
Na₂S+ Zn(NO₃)₂---->ZnS + NaNO₃ is 2, therefore option (b) is correct.
What do you mean by the balanced chemical equation ?A balanced chemical equation is an equation that has equal numbers of atoms for each element both on the reactant and product sides.
Methods to balance the chemical equation -:
The number of atoms for a given element is calculated by multiplying its coefficient with the element’s subscript in its chemical formula.
The coefficients in front of the formulas to show how many molecules of that material are used or produced.
Hence, the coefficient needed in front of NaNO₃ to balance the equation
Na₂S+ Zn(NO₃)₂---->ZnS + NaNO₃ is 2, therefore option (b) is correct.

During which phase does Earth see more than half of the moon's surface? first quarter third quarter waxing gibbous waning crescent
A: Frist quarter
b: third quarter
c: waxing gibbous
d: waning crescent
Answer:
c
Explanation:
During the "Third Quarter" phase, Earth sees more than half of the moon's surface. The correct option is B.
What is Waxing Gibbous and Waning Crescent?Waxing Gibbous and Waning Crescent are two phases of the Moon.
Waxing Gibbous is a phase of the Moon that occurs after the First Quarter phase and before the Full Moon phase. During this phase, the illuminated portion of the Moon is greater than half but less than fully illuminated, meaning it appears to be a "bulging" shape. The term "waxing" means that the illuminated portion of the Moon is increasing in size.
The Waning Crescent is a phase of the Moon that occurs after the Third Quarter phase and before the New Moon phase. During this phase, the illuminated portion of the Moon is less than half and decreasing in size. The term "waning" means that the illuminated portion of the Moon is decreasing in size. The crescent shape refers to the thin sliver of illuminated portion of the Moon that is visible during this phase.
Here in this question,
During the First Quarter phase, the right half of the Moon's surface is visible from Earth.
During the Third Quarter phase, the left half of the Moon's surface is visible from Earth.
During the Waxing Gibbous phase, more than half of the Moon's surface is visible, but Earth does not see more than half.
During the Waning Crescent phase, less than half of the Moon's surface is visible, and Earth does not see more than half.
Therefore, Option B i.e third quarter is correct.
