to establish a point from which to measure future distance, or if movement has occurred
this is the correct answer i took the test.
Yes. True vertebrates have a true head that develops from a neural crest of cells and hard structures surrounding the notochord.
The neural crest, which forms early in the development process in vertebrate embryos, is a fold on the neural plate where the neural and epidermal ectoderms converge. As an embryo grows, the neural crest produces neural crest cells (NCCs), which can differentiate into a variety of different cell types and contribute to tissues and organs.
The notochord is a temporary structure that plays a crucial role in higher animals. It secretes substances that communicate with all neighbouring tissues, telling them where they are and what will happen to them.
Therefore, True vertebrates have a true head that develops from a neural crest of cells and hard structures surrounding the notochord.

<h2>Plasma Osmolarity </h2>
Explanation:
- Osmolarity is the quantity of milliosmoles/liter (mOsm/L) of arrangement. It is the centralization of an osmotic arrangement. This is the normal bedside estimation utilized in clinical settings for osmotic action. Model: Plasma and other body liquid osmolarity: 270 – 300 mOsm/L.
- Plasma osmolality is an approach to gauge the electrolyte parity of the body. Osmolality (estimated by an osmometer in a clinical research center) is actually not the same as osmolarity, which can be determined dependent on the deliberate sodium, urea, and glucose centralization of the plasma. Osmolality is a proportion of osmoles of solutes per kilogram of an answer where osmolarity is a proportion of osmoles per liter of dissolvable.
