The process by which water-soluble nutrients are washed out of decomposing organic matter into the soil is called: MCQ with Answer and Explanation

Explanation:
Ribosomes are the only organelles common to both prokaryotes and eukaryotes, though sizes differ: 70S in prokaryotes, 80S in eukaryotes. Nuclear membrane, mitochondria, and Golgi are absent in prokaryotes. Ribosomes are the site of protein synthesis. This commonality supports the universal role of protein synthesis in all life forms. Mycoplasma, the smallest prokaryote, also has ribosomes.

Explanation:
In a closed circulatory system (e.g., humans, annelids, cephalopods), blood is always enclosed within vessels (arteries, veins, capillaries) and is distinct from interstitial fluid. Open systems (arthropods, most mollusks) have hemolymph bathing organs in sinuses. The lymphatic system returns fluid to blood. A portal system connects two capillary beds.

Explanation:
Pancreatic juice contains inactive enzymes like trypsinogen, chymotrypsinogen, and procarboxypeptidase. When trypsinogen enters the small intestine, it is activated into trypsin by the enzyme enterokinase (secreted by the intestinal mucosa). Trypsin then digests proteins into smaller peptides. Pancreatic amylase digests carbohydrates, and lipase digests fats.
