Epithelial tissue always has an exposed outer surface anchored to connective tissue by a thin, non-cellular structure called the basement membrane.
<h3>What is the basement membrane? </h3>
Thin layers of a specialized extracellular matrix that form the supporting structure supporting the growth of epithelial and endothelial cells are called the basement membranes. They surround the muscle and fat cells and the Schwann cells of peripheral nerves.
There is one common denominator regarding the basement membrane. This is because they are always in close opposition to cells.
It has been well demonstrated that basement membranes are not only for the provision of mechanical support and for dividing the tissues into compartments but also influence cellular behavior.
Collagen IV,laminin-entactin/nidogen complexes, and proteoglycans are the major molecular components of the basement membrane.
Therefore, epithelial tissue is anchored to connective tissue by a thin, non-cellular structure called the basement membrane.

Answer: wings: Insecta class
Chewing mouthparts: some orders in the insects class;
Jointed appendages: common to all athropods
Number of legs: not all the same in some class and even orders
Segmented bodies: common to all
Exoskeleton: common to all
Explanation:
Memeberss in the phylum athropoda all have exoskeleton with itsain component being chitin. They all have segmented bodies; some head, thorax and abdomen like insects, some head, cephalothorax and abdomen like in the crustaceans. All have jointed appendages. Some class possess wings eg insecta and some possess chewing mouthparts egg grasshopers in the class insecta
Values and attitudes are our basic premise to how our behavior is determined. Values can include belief systems which make up our prejudice, conceptualizations and impressions on a certain stimuli. Attitude includes our choice either to accept or reject a certain stimuli because of the values we possess.
Answer:
Role of organisms in the nitrogen cycle:
Bacteria play a central role: Nitrogen-fixing bacteria, which convert atmospheric nitrogen to nitrates. Bacteria of decay, which convert decaying nitrogen waste to ammonia. Nitrifying bacteria, which convert ammonia to nitrates/nitrites.
