    Which of the following has the mass closet in value to that of the positron

    If the binding energy of the deutrium is 2.23 MeV . The mass defect given in a.m.u. is

   Nuclear binding energy is equivalent to

    Which of the following particles are constituents of the nucleus

A double stranded helix that holds the code for all the cells in the body.

String-like structures inside the nucleus made up of proteins and deoxyribonucleic acid, better known as DNA.

Combinations made of protein and RNA that exit the nuclear pores and make proteins throughout the cell.

Helps assemble ribosomes, which are combinations made of protein and RNA (ribonucleic acid ).

In the middle of each nucleus. Main job is to make ribonucleic acid (RNA), which makes proteins that are essential to life.

Helps transport essential materials throughout the nucleus.

A gel-like fluid that holds things in place and helps to give the nucleus shape.

Tiny holes in the nuclear membrane that allow different cellular materials to come in and go out of the cell.

Made up of two layers (an inner and an outer), this acts like a cushiony outer shell of protection.

A jelly-like fluid that lls all the empty space in the cell, giving it shape and keeping everything in place.

The control center of the cell.
