The cell's structure is given by the cytoskeleton found in the cytoplasm of cells. The cytoskeleton is made up of complex fibers throughout the cell that was discovered after a second glance at cell with improved microscope technology. It serves the same purpose as bones and muscles in the body, aka, it forms shape, keeps organelles in place and directs movements of organelles.

The endoplasmic reticulum (ER) is a single membrane continuous with the nuclear envelope and a series of interconnected sacs thr
Solnce55 [7]

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,

Can someone pls help me ​
frozen [14]

Answer:

Explanation:

a. Since both the parents are carriers, they have one allele that is the gene for the normal trait and one gene that is for the sickle cell trait. So the genotypes of the parents are Hh

b.   If we use a punnett square:

                    H            h

         H       HH           Hh

         h        Hh           hh

Genotypic ratio: 1 HH: 2Hh: 1hh

Phenotypic ratio:      1 normal blood cell: 2 sickle cell carriers: 1 sickle cell disease
