Answer: For most of the life the chromosomes exists in a loose noodle like structure. They become compact to fit into a very small space.
Explanation: The chromosomes consists of a very long DNA that is linear. The liner DNA also has many proteins associated with it which is called as histone proteins.
These proteins fold and gets packed into a compact form from loose noodle or thread like structure.
This is necessary to get into a compact structure because being in linear form would require much space which is not possible. So as to manage the space and many processes like replication, repair and gene expression it is necessary for the chromosomes to get compact.
What force causes
venus to travel along a curved path instead of moving in a straight line
The force that causes
Venus to travel along a curved path instead of moving in a straight line is the
gravitational force between the Sun and the Venus. The more massive a body is,
the more it attracts bodies near it.
In the question, the number of atoms per unit cell is required for:
A) Polonium (Po)
In polonium, the structure is simple cubic, meaning there are 8 corner atoms, which add up to one atom per unit cell.
B) Manganese (Mn)
The structure of the Mn can be considered to be a body centered cubic (BCC) and the number of atoms for this is 8 corner atoms and 1 central atoms, making a total of 2 atoms per unit cell.
C) Silver (Ag)
Silver has a face centered cubic (FCC) unit cell structure, where there are 8 corner atoms and 6 atoms on the faces, so there are a total of 4 atoms per unit cell.
