Epithelial cells are of different types and are involved in the protection of the body's organs.
The epithelial tissues are important and they are the ones present on the topmost layer of the body and are responsible for the protection of the skin, and also form the lining of the urethra, uterus, etc.
Epithelial cells are divided on the basis of cell shape and it layering and cell shape, they are divided into squamous epithelium, cuboidal epithelium, and columnar epithelium and on the basis of layering, they are divided into simple, stratified, and pseudostratified.
The pseudostratified epithelial cells also have cilia which are hair extensions and they also have unicellular glands called goblet cells which secrete the mucus.
Stratified epithelium differs from simple epithelium because they are multilayered so help in mechanical and chemical support.
Keratinized epithelia are also present which are the upper layers or apical layers having resistant protein called keratin some epithelia also have a lower layer or basal layers due to which these cells also show polarity.
Transitional is helpful in stretching and that's why found in the lining of the urinary bladder.

Marcus really wants to ask Amy for a date but begins to sweat uncontrollably and finds
it hard to speak every time he even gets near her. Choose any three psychological approaches and describe how each might explain Marcus's behavior.
Psychological approaches that describe Marcus's behavior are Psychological sweating.
Psychological sweating is a physical reaction we attempt to suppress or, in the worst case, hide. Psychological sweating occurs all over the body surface in response to emotional stimuli including stress, anxiety, and pain, although it is particularly noticeable on the palms, soles, face, and axilla. High eccrine sweat gland concentrations at various bodily areas are mostly to blame for this. Eccrine sweat glands are activated by cholinergic innervation as the main effector during times of intense psychological stress.
73% of the approximately 800 men who participated in a Men's Health study stated they wished they could sweat less. Our romantic partners would like it if we did too: 84% of the 970 women surveyed thought it was disgusting when a man dews up on a date. "Sweating without command is like your body betraying you,"
Our bodies have apocrine and eccrine sweat glands. A thicker, stickier sweat made of proteins and lipids is produced by the apocrine, which is primarily found in and around your armpits and genitalia. Your entire body is covered in eccrine, which creates a main water and salt solution. The eccrine glands were once thought to be activated simply by a need for cooling, while the apocrine were thought to be activated by mental stress.

Why does the number of organisms decrease as you move up the pyramid?
the growth activity of the cell is an important role by chromatin it is also responsible for the metabolism of cell as well as the genetic functions of cells
Chromatin plays a important role in metabolism of cell and it regulates the genetic activities of the cell as well. To create chromosomes, chromatin fibers are coiling and condensing. Numerous cellular functions, including DNA replication, transcription, DNA repair, genetic recombination, and cell division, are made possible by chromatin.
The compactification of lengthy DNA strands is chromatin's primary function. The compartment in which DNA is housed in the nucleus is much smaller than the length of the DNA itself. The DNA needs to be compressed in some way in order to fit into this compartment. The degree of DNA condensing is measured by the packing ratio. DNA is not directly packaged into the structure of chromatin in order to obtain the overall packing ratio. Instead, it has numerous organizational structures.The process of transcription involves proteins reading the genetic data encoded in DNA, converting it into RNA, and then translating the RNA into useful proteins. No transcription happens if the chromatin becomes stronger and prevents access to the read proteins. Transcription can be carried out by euchromatin, an expanded kind of chromatin. While heterochromatin, a condensed form of chromatin, is crammed too closely together for proteins to read DNA.All DNA-based processes are hindered by the way DNA is wrapped up in chromatin. Chromatin can easily change its shape and structure because of the very dynamic way that proteins and DNA are arranged. At the site of DNA damage, chromatin relaxes quickly, allowing repair proteins to connect to the damaged DNA and repair it.So, for genome replication, transcriptional silencing, DNA repair, and recombination, chromatin architecture is essential.
