Answer:
Pseudoscience
Explanation:
Phrenology according is the study of bumps on the head to predict a person's personality or behavior.
It is regarded as a pseudoscience because science involves having experiments and laws which can be replicated in any part of the world.
However Phrenology was regarded as a pseudoscience and rejected after scientists failed to replicate Gall's claims, and 200 years of subsequent neuroscience has shown phrenology to be false.
Answer:
The neutrophil forms multiple lamellipodia extensions
Explanation:
Neutrophils are white blood cells (granulocytes) which comprise the first line of defense in the innate immune system. The lamellipodium (in plural, lamellipodia) is a cytoskeletal actin extension found in mobile cells, whose main functions are cell motility and migration. Rac1 is a member of the Rho GTPase protein family which is involved in actin-myosin cytoskeletal reorganization of neutrophil cells in response to microorganism infections. In this regard, it has been shown that Rac1 controls the initial uncapping of actin ends in order to regulate cytoskeleton dynamics, thus regulating lamellipodia formation. By using mice as models, researchers observed that Rac1 constitutive activation may lead to the formation of multiple lamellipodia in neutrophils.
