Photosynthesis is c because plants "exhale" into the atmosphere.
If you are referring to the first question then it is probably A but there's no way to know because we can't see all of space but the milky way is inside the universe not the other way around and therefore it can't be B or C and D just doesn't make sense.

If GFR is 125 ml/min, and you are studying a drug that has a renal clearance rate of 20 ml/min, you can conclude that
ahrayia [7]

Answer:

(B). The drug is reabsorbed.

Explanation:

Renal clearance rate determines the excretion of drugs into the urine during excretion. It is used to study the main process associated with a drug's renal excretion.

When the renal clearance rate is lower than GFR (glomerulus filtration rate), the drug is absorbed in the renal tubules. When the renal clearance rate is higher than GFR, the drug is secreted into the urine. When the renal clearance rate is equal to the GFR, the drug is neither reabsorbed nor secreted.

As for given drug, renal clearance is 20 ml/min (less than GFR), this drug will reabsorbed.

Thus, the correct answer is option (B).

How does igneous rock become sedimentary rock?
Zinaida [17]

Explanation:

Igneous rock can form underground, where the magma cools slowly. Or, igneous rock can form above ground, where the magma cools quickly. When it pours out on Earth's surface, magma is called lava. In this way, igneous rock can become sedimentary rock.

Any rock (igneous, sedimentary, or metamorphic) can become a metamorphic rock. If rocks are buried deep in the Earth at high temperatures and pressures, they form new minerals and textures all without melting. If melting occurs, magma is formed, starting the rock cycle all over again.
