The nucleus of a cell contains which is the physical carrier of inheritance.

The nucleus of a cell contains deoxyribonucleic acid DNA, which is the physical carrier of inheritance.

Explanation:

DNA is a double helical structure present in the cells of all living organisms as a basis of the information for the inheritance, growth , maintenance and repair.  It is made up of four nitrogen bases known as adenine, thymine, cytosine and guanine. Each of these bases are arranged in an organised manner while they are attached to a sugar moiety and a phosphate backbone to form the complex double helical structure. During the event of a cell division the DNA is copied and is equally distributed into all the daughter cells .

prokaryotic cells do not have a nucleus in which the dna is stored in, it floats freely inside the cell.

eukaryote cells do have a nucleus in which the dna is stored in.

what statement best describes the difference between the sympathetic and parasympathetic nervous systems?

the sympathetic nervous system prepares the body for intense physical activity and is often referred to as the fight-or-flight response. the parasympathetic nervous system has almost the exact opposite effect and relaxes the body and inhibits or slows many high energy functions.
