Ectoderm refers to one of the three primary germ layers found in the initial phase of an embryo. The other two layers are the endoderm (the most proximal layer) and the mesoderm (the middle layer), the ectoderm is the most distal or the exterior layer. It originates from the external layer of germ cells.
Generally, ectoderm in vertebrates further develops into the brain and the nervous system, and into the parts of the skin. So, in the given case of the mouse, one would easily find the marker in the nervous system and in the epidermis.
Answer:
Diagram D
Explanation:
When electrons absorb energy, they move to higher orbital levels. The highest energy levels are the furthest from the nucleus. More energy is needed to occupy higher energy levels. Therefore, the electron which must have absorbed the most energy is in Diagram D. In this diagram, the electron absorbs enough energy to move it from n = 1 to n = 4.
RNA reads and translates the DNA code.
Answer:
cellular shrinkage and metabolic dysfunction.
Explanation:
In dehydration, fluid from the extracellular compartment is depleted first, followed by fluid from the intracellular space. Fluid loss from the intracellular space results in cellular shrinkage and metabolic dysfunction. Dehydration occurs because of decreased water intake, increased fluid loss, or both.
I believe the answer is photon
