In eukaryotic cells, dna is packaged with proteins into structures called chromosomes. what advantage do chromosomes provide the cell?

a.
they allow all genes to be expressed at the same time.

b.
they allow random distribution of genetic material when a cell divides.

c.
they ensure equal division of genetic material when a cell divides.

d.
they eliminate the need for a nuclear membrane.

Eukaryotic cells have well-developed organelles. The cells consists of nucleus, inside which DNA is packaged in chromosomes. The chromosomes provide an advantage to the cell that is:

Option C. They allow random distribution of genetic material when a cell divides.

The DNA is packaged in the chromosome with the help of chromatin. The packaging of chromosomes makes it easy for the cell to undergo meiotic division. When the cell divides during meiosis:

Therefore, the random distribution of chromosomes provide variation and unique combinations.

Option C, They allow random distribution of genetic material when a cell divides.

Explanation:

The chromatin are responsible for packaging of DNA molecule into smaller space with in a chromosome. It not only package it but also protect it from. Packaging allows for easier division of cells during mitosis and meiosis and hence prevent any kind of damage to the DNA.  

Chromosomes make recombination and random segregation of genetic material to form new cells.  Each new cell gets equal number of chromosomes

Hence, option C is correction

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.

the correct answer is 2 and 4
