Explanation:
vesicular transport
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).
Answer:
The animals present body structure is due to evolution. It is seen in each part including the structure of the heart. The vertebrate heart becomes complex from a simpler form.
Invertebrates, the heart of fishes is two-chambered having one auricle and one ventricle. The deoxygenated blood gets purified in the gills. They are aquatic and no lungs for breathing. The hearts pump a mixture of oxygenated and deoxygenated blood to the body.
The amphibians and reptiles have 3 chambered heart as they lead terrestrial mode of life. The gills modified into the lungs. The left auricle receives pure blood and the right auricle receives deoxygenated blood. The blood purified in the lungs and in the ventricle, both types of blood get a mix. The ventricle pumps the mixed-blood throughout the body.
In the case of birds and mammal, the heart is 4 chambered and the oxygenated and deoxygenated blood are separated. These two are higher vertebrates. No mix of pure and impure blood, the body receives only the oxygenated blood.
This shows to construct the phylogenetic tree of vertebrates - the fishes should be in the bottom, and above it amphibians, reptiles, then, mammals and birds on the top branch of the tree. As the chambers and structure of the hearts modified one after another.
Decomposers are those organisms that recycle matter in the ecosystem.
