After a protein is synthesized, it can undergo several subsequent processes. Process that a protein always undergo sooner or later is : degradation via proteasomes.
What happens after protein synthesis?After being synthesized, the protein is carried in a vesicle from the RER to the cis face of the Golgi. As the protein move through the Golgi, it can be modified.
After a polypeptide chain is synthesized, it may undergo additional processes, such as it may assume a folded tertiary shape due to interactions among its amino acids. It may bind with other polypeptides or with different types of molecules, such as lipids or carbohydrates.
The first step in protein synthesis is called transcription that is the process wherein DNA is used to create mRNA. mRNA is produced using DNA's code, which is within the cell's nucleus.

A putative male chemo-signal called androstadienone has been linked to sex variations in hypothalamic activity in adult heterosexual men and women. We used functional magnetic resonance imaging to examine the hypothalamic responsiveness to this chemo-signal in 39 pre-pubertal and 41 adolescent boys and girls in order to determine if puberty moderated this sex difference in response to androstadienone. The next step was to determine whether the sex-atypical (in accordance with the experienced gender) rather than the sex-typical (in accordance with the natal sex) hypothalamic activations during androstadienone-induced olfactory stimulation were present in the 36 pre-pubertal children and 38 adolescents with gender dysphoria (GD; DSM-5) diagnoses.

which accessory structure of the hair is likely to be malfunctioning in a patient with a dry scalp?
The hair is likely to be malfunctioning in a patient with a dry scalp hypodermis.
The hypodermis is the lowest layer of skin on your body. It has many critical functions, which include storing strength, connecting the epidermis layer of your pores and skin on your muscle tissues and bones, insulating your body, and protecting your body from harm. As you age, your hypodermis decreases in length, and your pores and skin starts to sag.
Adipose tissue present in the hypodermis consists of fat-storing cells called adipocytes. This stored fat can function as a strength reserve, insulate the frame to save you warmness loss, and act as a cushion to protect underlying systems from trauma.
The subcutaneous tissue, also known as the hypodermis or superficial fascia, is the layer of tissue that underlies the pores and skin. The terms originate from subcutaneous in Latin and hypoderm in Greek, each of which implies “beneath the pores and skin,” as it is the deepest layer that rests just above the deep fascia.

How do tephritid flies mimic the territorial display of jumping spiders?The tephritid fly Zonosemata vittigera (Coquillett) has leg-like patterns on its wings and a wing-waving display that together mimics the aggressive territorial display of the jumping spider (Salticidae). Zonosemata flies initiate this display when chased by a jumping spider, causing the spider to turn backwards and retreat. Wing transplantation experiments showed that effective mimicry required both wing patterns and wing wave representations.

Answer:
Hope this helps!
Explanation:
Animal testing is necessary because alternative methods are currently not as reliable. The reason why animals are used in testing products that will be used by humans is the physical make-up of animals that has a great degree of resemblance to that of the human body. This physical resemblance enables scientists and researchers to gather biological data and information that are needed for developing medicines. This biological information also happens to be unavailable in plants and while there have been recent development in the use of non-animal methods such as computer modeling, and in vitro and genetic research, these methods were not developed to replace animal research but simply to supplement it (Trull, 2002, p. 45). Moreover, these non- animal methods are still being developed which necessitates that testings must continue to be done to an intact living system which is an animal (Guither, 1998, p. 80). In addition to this, there has been difficulty in the scientific community as to finding competent, safe and reliable alternatives to animal tests. This is because it takes several years to validate alternative methods and those methods that are currently available were developed without using the latest technology (Daston & Mcnamee, 2005). Thus, the use of animals to determine the effectiveness, toxic level and possible side effects of drugs, cosmetics and other products remains to be the primary and most reliable method that is available today.
Animal testing is necessary to secure humans from unsafe and dangerous medications and products. Animals are not only used to test the effectiveness of new medications and products. They are also used to check the safety of products so no human users will be harmed when using them. If products are sold in the market without being tested on animals, users of these products which range from medicines, cosmetics and household products are put in danger. Products that have not undergone animal testing are generally considered as unsafe and may imperil the lives of their users. This is demonstrated by several medical tragedies that have
occurred because humans have used products and substances that were not used first or experimented on animals. In the 1930’s, for example, a number of women lost their vision and at least one was reported to have died for using an eye mascara that contains a substance that can cause corneal ulceration in the eyes of its users (“The Care of Use”, 2002). The substance called p-phenylenediamine was not tested on animals. Another tragedy which happened because no animal testing was conducted was the case of an antibacterial medicine that was dissolved in an antifreeze. The medicine was marketed without prior animal tests and since antifreeze is toxic, the medicine has resulted in the death of 107 people (“The Care of Use”, 2002). Animal testing therefore guarantees the safety of using drugs and similar products.
Animal testing is necessary because it is unethical and dangerous to experiment with untested substances using humans. The welfare of humans and human life are more important and valuable than that of any animal. This is the reason why it is unethical and dangerous to use humans to test new drugs and substances. By using animals in research and experiments, medical researchers will be able to determine the safety and effectiveness of medicines and other products without risking the lives and safety of human subjects. This explains why animal test results on new drugs have to be evaluated by the Food and Drug Administration (FDA) “to determine whether the drug is safe enough to test in humans and, if so–after all human testing is completed –to decide whether the drug can be sold to the public” (Cohn, 1987). By trying on potential substances and formula on animals, researchers will also be able to determine the harmful side effects of medicines and similar products they are experimenting on. If tested products were found safe and effective, they can be used by humans. If animals are not used to determine the safety and effectiveness of products, humans will be obliged to try them which may have disastrous and dangerous consequences. Government regulations therefore necessitates that substances should be tested on animals first before trying them on humans. The importance in the use of animals in preliminary experiments and research is currently evident in
the development of medicines for AIDS. A substances that is suspected of being potential in curing the disease is tested first on animals “to find out how it works in the body, what unwanted side effects it can cause, and if it is effective against the illness” (Segal, 1987).

Discuss voluntary and involuntary actions in movement. Include skeletal tissue, cardiac tissue, and smooth tissue in your response.
Voluntary and involuntary movements are divided due to differences in the nervous system involved and differences in muscle type use.
Voluntary Movements
Voluntary movements or movements that we are aware of are movements that are regulated by the somatic nervous system. For example, when there are thoughts of our own to eat. Then the brain will think to take food from the plate, put it in the mouth, move the jaw to chew, and with the help from tongue we swallow it. That is called voluntary movement or movement that we are aware of.
Voluntary movements are easily identified with us being able to start and stop them as we wish. For example, when we chew we want to stop, of course we can, right? Voluntary movements can be performed using the skeletal muscles. So only the muscles attached to the skeleton of the body that can be moved voluntarily.
Involuntary Movements
Whereas involuntary movements are the opposite, movements that we are not aware of and are regulated by the autonomic nervous system. For example, after swallowing food, it goes into the esophagus. In the esophagus, peristaltic movement is carried out by the muscles in the wall of the esophagus to make food reach the stomach.
Why is this movement called involuntary movement? Because we can’t control peristaltic movement the way we want. As soon as food enters the oesophagus, peristaltic movement begins. Even in the middle we can not stop the peristaltic movement. Involuntary movements can be carried out by smooth muscles and cardiac muscles, which are muscles located in internal organs.
