What molecule??
I'm assuming the answer would be by diffusion.
Costa Rica is surrounded by the Pacific Ocean and the Caribbean Sea. It also borders the Gulf of Nicoya.
Mostly bacillus (bacteria with cylindrical/rod shaped morphology) I'm pretty sure, you don't see any type of coccus (bacteria with spherical morphology) with flagella.
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.
