Do all connective tissues arise from an embryonic tissue called mesenchyme?
Yes, most connective tissues arise from mesenchyme, an embryonic tissue. Mesenchyme gives rise to fibroblasts, which then differentiate into various types of connective tissue cells and produce the extracellular matrix. However, some specialized connective tissues like blood and lymph do not directly arise from mesenchyme.
What do the mouth absorb?
The mouth absorbs water, electrolytes, and some medications through the mucous membranes in the lining of the mouth. These substances can enter the bloodstream directly through these membranes.
How do Unicellular organisms exchange gas eliminates wastes and absorbs nutrients?

Membranes that line body cavities that open directly to the exterior are?
These membranes are called mucous membranes or mucosa. They secrete mucus to protect the lining and provide lubrication for various body cavities that are exposed to external environments, such as the respiratory, digestive, and reproductive systems.
Pleura are examples of which type of membrane?
Pleura are examples of serous membranes, which are thin membranes that line body cavities not directly open to the outside of the body. They consist of two layers - parietal (lining the cavity walls) and visceral (covering the organs).
Do membrane bones develop from hyaline cartilage structures?
No, membrane bones do not develop from hyaline cartilage structures. Membrane bones are formed directly from mesenchyme tissue through intramembranous ossification, while hyaline cartilage serves as a precursor for endochondral ossification, where bones are formed by replacing cartilage with bone tissue.
Why does a 16 foot fence arranged 1 ft by 7ft make a smaller area than when arranged 3ft by 5ft?
Because Area and Perimeter are not directly linked. If you were to make the fence into a triangle you would get another area, a circle would give a fourth.
What organelle in plants which is directly responsible for photosynthesis is?
Chloroplasts are the organelles in plants that are directly responsible for photosynthesis. They contain chlorophyll, a pigment that captures sunlight and converts it into chemical energy through the process of photosynthesis.
What are the membranes that line the body cavities that open to the exterior of the body?
The membranes that line body cavities open to the exterior are called mucous membranes. They are made up of epithelial tissue and are found in areas like the respiratory, digestive, and reproductive tracts. Mucous membranes help protect the body by secreting mucus and trapping pathogens.

What types of nervous cells are in the spinal nodes?
The perikaryon (cell body) is the neuron central part, to other neurons or directly to muscles or glands. These sheaths are composed of cell membranes from Schwann cells.
