HELP ASAP I NEED IT IN 45 MINSSS Which best describes how DNA fits inside a cell nucleus?
A. DNA folds into stacked layers called chromatin, which then squeeze into the nucleus.
B. DNA is double-stranded, so one strand is inside the nucleus and the other wraps around the nucleus.
C. DNA tightly coils around proteins and condenses into chromosomes, which fit in the nucleus.
D. DNA is naturally much smaller than the cell nucleus so it easily fits inside the nucleus.

the answer would be a

hey there!

mass = 6.75 g

volume =   9 cm³

therefore:

d = mass / volume

d   = 6.75 / 9

d = 0.7 g/cm³

answer b

the term hydride is commonly named after binary compounds that hydrogen forms with other elements of the periodic table. hydride compounds in general form with almost any element, except a few noble gases. the trends and properties vary according to the type of intermolecular force that bonds the elements together, the temperature, its molecular masses, and other components. hydrides are classified into three major groups, depending on what elements the hydrogen bonds to. the three major groups are covalent, ionic, and metallic hydrides. formally, hydride is known as the negative ion of a hydrogen, h-, also called a hydride ion. because of this negative charge, hydrides have reducing, or basic properties. its special characteristics will be further discussed.
