Answer:
The transport of proteins and other bioactive materials from endoplasmic reticulum to the nucleus without the involvement of transport vesicles is the main beneficial for the cell to be continuous with the nuclear envelop.
Explanation:
The rough endoplasmic reticulum or RER that contain ribosomes on its surface is directly continuous with membrane of nucleus.
This helps nucleus to gain access to the proteins and other materials generated within endoplasmic reticulum.
If endoplasmic reticulum faces biological problems such as unfolded protein accumulation in the ER is hazardous to the cell.During such circumstances ER send specific signal to the nucleus.
The nucleus respond to that signal by reducing the rate of protein synthesis,so that the ER would get some extra time to fold the required proteins essential for cellular functioning,
Bacteria in general grow optimally when the pH is around 7 (5-9 let's say). That is not to say that there are not bacteria that grow in extremely acidic conditions, like in our stomach, or others in extremely basic conditions, like the conditions near volcanoes. Nonetheless, bacteria that grow in food prefer acidic environments over basic ones and usually cannot tolerate the acidity of fruits which is around 4 pH for the most acid ones. For example, stuff like milk and bread that have a pH from 5-6 are prime examples of food where bacteria would thrive. Thus, the correct answer would be b.
Chromosomes are found in the nucleas of a human cell and are carrier of generic information and responsible for the transmission of these information from one generation to another

i realy dont konw but you can still eaxplain
The Urinary bladder controls the elimination of urine from the body.
- The lower abdomen contains this triangle-shaped, hollow organ. Ligaments that are connected to the pelvic bones and other organs hold it in place.
- When storing pee, the bladder's walls relax and expand; when emptying urine through the urethra, they contract and flatten.
- The typical healthy adult bladder has a two to five-hour storage capacity of up to two cups of urine.
Three parts of bladder allow urine to be discharged:
- A pair of sphincter muscles. By tightly shutting around the bladder opening like a rubber band, these circular muscles assist prevent urine leakage.
- In the bladder's nerves. When it's time to urinate or empty the bladder, the nerves let the person know.
- Urethra. Urine can travel through this tube and leave the body. Urine leaks from the bladder as a result of the brain's tightening signal to the bladder muscles.
