8th Grade Math, Hel Now Pl! What is the function of the nucleus in plant and animal cells? A. Produces all the power of the cell B. Creates proteins within the cell C. Control all cells activity, contains DNA D. Allows things in an out of the cell

C. Control all cells activity, contains DNA

Step-by-step explanation:

The nucleolus makes ribosomal subunits from proteins and ribosomal RNA, also known as rRNA. It then sends the subunits out to the rest of the cell where they combine into complete ribosomes.

Also that's not math.

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
