Answer:
[D]. None of the above
Explanation:
Epithelium are one of the type of four tissues found in living systems. They possess a variety of functions and are found to line/cover the surfaces of most organs. Epithelial tissues are classified based on the number of cell layers (simple and stratified) and shape (squamous, columnar, and cuboidal).
Based on their shape;
- Squamous epithelium are made up of scale-like flat cells that line the surfaces of alveoli of the lungs etc. They are of thin, flat, irregular shaped cells which fit together like floor tiles to form a compact tissue as stated in this question.
- Cuboidal epithelium contains cells whose shape are similar to that of a cuboid i.e. close width and height. They are located in the kidney tubules, thyroid vesicles and in glands like pancreas.
- Columnar epithelium are relatively thin and elongated in shape, hence, they are found in organs and surfaces whose function mainly is absorption and secretion.
Hence, NONE of the mentioned statements are UNTRUE
Answer:
they both have a plasma membrane and protoplasm
they both contain DNA
Expendable can mean having little to no value when compared to the big picture or something that's designed to only be used once and then destroyed. Since I don't have any context, I can't decipher which one it would be.
To distinguish between somatic and autonomic nerve fiber is if the somatic nervous transmits sensory and motor signals to and from the central nervous system and if the autonomic nervous system controls the function of the organs and glands
The thymus gland is actually composed of lymphoid tissue and is located in the mediastinal cavity, in front of and above the heart.
<span>The thymus gland is a two-lobe primary lymphoid organ which has an important role in immune function. It secretes thymosin hormone which stimulates the maturation of T cells. So, the thymus is a place where T cells mature. This organ is most active during<span> the neonatal and pre-adolescent periods.</span></span>
