The islets of Langerhans are microorgans located in the pancreas.
<h3>The islets of Langerhans </h3>
The islets are formed by polygonal or rounded cells, arranged in cords, around which there is an abundant network of blood capillaries with fenestrated endothelial cells.
<h3>Types of islets of Langerhans</h3>
- Alpha (A) cells: secrete glucagon. In humans, these cells have regular-shaped granules containing a dense center surrounded by a clear region under the membrane.
- Beta (B) cells: secrete insulin and amylin. B cells have irregular granules with a center formed of irregular crystals of insulin complexed with zinc.
- Delta cells (D): synthesize somatostatin.
- PP (F) cells: contain a pancreatic polypeptide.
With this information, we can conclude that the islets of Langerhans are microorgans that constitute a large production of products for the maintenance of life.

Dominance
because he taught and studied to his associates that when you combine a dominant trait with a less dominant or more passive trait you get more offspring ( doesnt matter really) with the dominant trait ... for example brown hair and brown eyes is more dominant then blonde hair and blue eyes or green or blue eyes etc or with certain products like the pea experiment where some came out lighter then the others and it was a direct problem for him because he knew that it would be harder finding the dominant trait this way
if i helped plz mark brainliest

A follicle releases an egg into a fallopian tube.
The Lock-and-key mechanism was first proposed by Emil Fischer which described as the enzymatic reactions whereby an enzyme with a single substrate binds temporarily to form a substrate complex.
The lock-and-key mechanism is usually associated with the complementary shapes of an enzyme with a single substrate, wherein the lock that is being referred to is the enzyme and the substrate is the key. One right sized substrate (key) fits into the active site (key hole) of the enzyme (lock).
The active site which is mentioned above is structurally complementary to the substrate. This is the temporary binding site on the enzymes. Just like a lock and key, the enzyme as the lock and the substrate as the key is said to fit together.
