neural plate
its the embryonic origin of biological enzymes.
Nervous tissue would be the most responsive. For example, the eyes respond to changing light intensity, blood flow, hair orientation and lung bronchioles all respond to changing temperature. The skin (melanocytes) also respond to UV radiation over time.
The features that all connective tissues share in common isFibroblasts. Fibroblasts are typically responsible for the formation of the acellular matrix.Connective tissues that have this common trait include bone and cartilage, but exclude blood (which meets all the connective tissue criteria) and loose connective tissue.^True, but I think what he's looking for is this:o Common origin - all arise from mesenchyme (an embryonic tissue)o Degrees of vascularity - cartilage = avascular, dense connective tissue = poorly vasculated,o Extracellular matrix - comprised of nonliving extracellular matrix
connective tissue.That tissue is called as connective tissue.
it's called the phloem. the tissue type is meristematic tissue.
Mesenchyme
Undifferentiated mesenchymal tissue

One major difference between adult and embryonic stem cells is their different abilities in the number and type of differentiated cell types they can become. Embryonic stem cell can become all cell types of the body because they are pluripotent. Adult stem cells are thought to be limited to differentiating into different cell types of their tissue of origin.
Nervous tissue would be the most responsive. For example, the eyes respond to changing light intensity, blood flow, hair orientation and lung bronchioles all respond to changing temperature. The skin (melanocytes) also respond to UV radiation over time.
Nervous tissue stops dividing while still in the fetal phase.
No, human tissues are arise from one of 3 embryological origins: 1- Ectoderm 2- Mesoderm 3- Mesoderm
A cuticle is not tissue because it is a stack of chemicals. This chemical stack just sits on top of the layer of cells. Tissue is a group of cells that perform a function, while a cuticle is just a simple coating.
Scientists wish they knew. Something as of yet undetected interferes between the genetic and cellular level causing a gap in the embryonic neural tube. The neural tube is a precursor to the CNS which includes the spine, cord and brain.With all they do know, down to the days of embryonic development when the cells should fuse to reducing the chance to 1% through the use of Vitamin A and a few known risk factors such as diabetes, fever, medication and obesity; most babies are still being born to women with no known factors.
