which type of virus is most likely to cause cell lysis and rupturing of an infected animal cell when it is released?
Extreme pH, heat, dryness, and uncomplicated disinfectants are less effective against non-enveloped viruses.
Norovirus, enterovirus, adenovirus, and rhinovirus are a few examples of non-enveloped viruses. Viruses with an envelope are typically less virulent.
A phage behaves like a typical virus during the lytic cycle by stealing the resources from its host cell to produce numerous new phages, which ultimately causes the host cell to lyse (burst) and die.

in response to falling blood glucose levels, which pancreatic islet cell releases glucagon?
A hormone called glucagon is important in regulating blood sugar (glucose) levels. It is synthesized by alpha cells and then released into the bloodstream from the pancreatic islets of Langerhans.
When blood glucose levels are too low, the pancreas releases more glucagon into the body (low blood glucose). In numerous ways, this hormone aids in the recovery of blood glucose: As a result, the liver releases glucose into the bloodstream after converting stored glucose into a usable form. Alpha cells in the islets of Langerhans secrete glucagon, and beta cells secrete insulin. The hormones insulin and glucagon control the body's glucose level to maintain it within a healthy range.
We can therefore conclude that glucagon, a hormone, is crucial for controlling blood sugar (glucose) levels. The pancreatic islets of Langerhans' alpha cells are responsible for their production.

In terms of ecological impact, shrimp farming is less destructive than shrimp trawling - False
The primary goal of commercial shrimp fisheries is to maximise their target catch in order to maximise profit. Using trawl nets, commercial shrimp fisheries achieve this purpose. Trawling is a particularly damaging type of fishing that, regrettably, ignores the effects on the environment. Trawling with beam or otter trawls increases the amount of shrimp that can be caught, but it also increases the amount of by-catch that can be landed. By a wide margin, by-catch outweighs shrimp and other target species that are collected in trawls. Most by-catch, which includes young fish, non-commercial fish, and benthic debris, is landed and thrown back into the water dead. By-catch is then dumped into the water, where it contaminates it and kills fish.

Which pituitary hormone causes a decrease in the amount of water lost in the kidneys?
The pituitary hormone that causes a decrease in the amount of water lost in the kidneys is the antidiuretic hormone (ADH).
ADH is produced in the hypothalamus and released by the pituitary gland into the bloodstream. ADH works by increasing the permeability of the cells that line the collecting ducts of the kidneys.
This increases the reabsorption of water back into the body, thus reducing the amount of water that is lost. ADH also increases the permeability of the distal convoluted tubules, which allows for increased absorption of sodium and chloride.
The increased absorption of these ions helps to draw more water from the interstitial space, further reducing the amount of water that is lost. Additionally, ADH causes the release of aldosterone from the adrenal cortex, which helps to increase the retention of sodium and water in the kidneys.
Overall, ADH helps to reduce the amount of water lost in the kidneys and maintain a proper balance of water and electrolytes within the body.
