Answer:
Comparison stress
Explanation:
The Stress that is responsible for the change in shape of the material is called as Compression Stress.
1. Passage of a sperm through the corona radiata of the oocyte.
2. Penetration of the zona pellucida.
3.Fusion of the plasma cell membranes of the oocyte and sperm. after fusion the sperm head and tail enters the oocyte but plasma membrane of sperm doesn't.
4. Completion of the second meiotic division of the oocyte. this creates female pronucleus and polar body 2.
5. Formation of the male pronucleus (nucleus of sperm enlarges)
6. Breakdown of the pronuclear membranes and restoration of diploid number of chromosomes.
Answer:
Lysogenic replication cycle is one unique process in T7 virus replication.
Explanation:
The T7 virus is a virus that attacks bacteria ( bacteriophage). Unlike other viruses (plants and animals viruses), it replicates within the host cell by means of two cycles: the lytic replication cycle and the lysogenic replication cycle.
Virulent phages replicate through the lytic replication cell and this lead to the death of the cell through cell lysis.
The lysogenic replication cycle involves bacteriophages known as temperate bacteriophages. Temperate bacteriophages can become part of a host chromosome forming a prophage. The prophage replicates with the formation of daughter cells with incorporated viral genetic materials until when induced to enter into the lytic stage thereby producing new viruses which then exit the host cell by cell lysis.
This process of incorporation into the host cell genome is known as lysogenic replication and is unique to the bacteriophages.

1. They have a nucleus which serves a great function in many cellular activities. <span>Nucleus,
the control center of the cell is the organelle which intiates,
enables, and manages the various simplex. compound and complex cellular
activities. It also stores the DNA of the cell which is then replicated
and recopied over a hundredth and thousandth times over through cell
division processes. In the nucleoplasm -nucleolus, the inner part of
nucleus of a cell is where the DNA to mRNA and to protein; vice-versa
happens. <span>
2. Muticellular organisms have improvised mitochrondria and chloroplast vital for many functions.</span></span></span>
