COMPARE: Identify three ways that a biologist’s research is similar to an astronomer’s.
dalvyx [7]
  1. Biologist and astronomer both use tools that magnify  so they are able to view minute objects. Astronomers use telescopes while biologists use microscopes.
  2. They both require data science due to the enormous data they are collecting that needs to be analyzed. Astronomers are collecting data on millions of stars and galaxies. Biologists require data science to analyze the enormous genomic data from populations.
  3. Both fields involve making new  discoveries due to the enormity of the scale in their scopes. Biologists and astronomy attempt to find new planets and those that could harbor extra-terrestrial life while biology attempts to find new undiscovered species of organisms on earth.

Explain the volume of ideal gasses as related to the molar concept.
horrorfan [7]

Answer:

n = Initial volume/22.4L

Explanation:

The molar concept is simply one that is used to find the Number of moles and explain the relationship it has with avogadro's number, molecular mass, molar mass e.t.c.

Now, in terms of molar mass, number of moles is given by the formula;

n = mass of the sample/molar mass

In terms of avogadro's number, number of moles is;

1 mole = avogadro's number = 6.02 × 10^(23)

Now, when dealing with ideal gases, the molar volume of an ideal gas is 22.4 L.

Now the relationship between this volume and the mole concept is that the number of moles is gotten by dividing the initial volume by this molar volume.

Thus;

n = Initial volume/22.4L

Processes that increase the density of seawater include evaporation and _____.
Elena L [17]
Correct Answer: option C: Formation of sea ice

Reason: 
<span> In cold regions, changes in salinity alters the water present in ocean. Further, water density also changes with temperature. In general, water density in ocean water increases with decreasing temperature. This is because,  when salt is ejected into the ocean as sea ice forms, the water's salinity increases. Since, salt water is heavier, the density of the water increases.</span>
