Mitosis follows a very precise process, but cytokinesis does not; why do you think a precise process is not required for cytokinesis?

Answer and Explanation:

Mitosis pursues an extremely exact procedure, yet cytokinesis doesn't as in that anything incorrectly occurs in the development of daughter nuclei in meiosis or mitosis the entire daughter cells may breakdown or dead or they will be imperfect in these two cases yet cytokinesis doesn't require exact system its alright if daughter cells are of various sizes or shape it won't influence result of cells.

Mitosis is required to maintain the chromosome number of parent cells in daughter cells. Cytokinesis is not precise since most of the vital organelles can divide to form new organelles.

Explanation:

Orderly events of mitosis ensure that the daughter cells obtain the same number of the chromosome as it was present in the parent cells. A daughter cell with fewer or more chromosomes than the parent cell, abnormal chromosome number would affect its survival. Mostly, the cells with abnormal chromosome numbers do not survive or cause genetic disorders.  

On the other hand, cell organelles such as mitochondria and chloroplasts are semi-autonomous. These organelles can divide to form more of their types if required. The presence of genetic material in the nucleus poses the need for precise events of mitosis to maintain the chromosome number of species in each of the daughter cells.  

answer: zinc is the substance which has a volume of 1.38 .

density is defined as the mass of an object per unit volume.

it can be calculated by dividing mass of a substance by its volume i.e.

si unit of density is kg per cubic meter and cgs unit of the same is gram per cubic centimeter.

now from the given data volume can be calculated by the formula .

hence, the volume of aluminium will be = which comes out to be 1.703 .

similarly, volume of zinc, chromium, and nickel will be 1.378 , 0.869 , and 0.356 respectively.

the circled areas are referred to   as sunspots.   the sunspots are cooler than the   surrounding area.

sunspots are temporary phenomena on the photosphere of the sun that appear visibly as dark spots compared to surrounding regions. they correspond to concentrations of magnetic field flux that inhibit convection and result in reduced surface temperature compared to the surrounding photosphere.
