The small part of the nucleus where ribosomal subunit formation takes place is called the nucleolus. This structure is found in eukaryotic cells and takes up about 25 percent of the volume of the nucleus. This structure is said to be the brain of the nucleus. It is made up of ribobucleic acids or the RNA and proteins. Its primary function is to transcript the ribosomal RNA (rRNA) and to combine these with the proteins resulting to the formation of an incomplete ribosome. Since it is closely related to a chromosomal matter of a cell and important in the production of ribosome, this structure is correlated to be one of the cause of a number of diseases.
Answer:
cd
Explanation:
image is formed due to reflected light rays and it is enlarged because image distance/ object distance = height of image/height of object
v>u so image is enlarged
<span>c. remains the same

As electrical energy is converted into heat energy, the total amount in the system remains the same

according to law of conservation of energy
Answer: Collide, Collision, Collide, Proper Orientation and Energy
Explanation:
The basic premise of the collision theory is that particles must first collide if a reaction is to occur. Additionally, that collision must be effective. To be effective, the particles must collide with the proper orientation and the proper amount of energy.
