Answer:
The correct answer is - 25600 bacteria.
Explanation:
Bacteria can divide and produce double their population very quickly. As mentioned in the question bacteria multiply every 15 minutes to their double number. Finding the number of bacteria after 2 hours is simple mathematics. Two hours means 120 minutes and dividing it to 15. The result will be 8 which mean the bacteria double their colony 8 time so,
100×2 to the power 8 = 100 (initial number of bacteria)×2×2×2×2×2×2×2×2= 25600
Thus, the correct answer is option- 25600 bacteria.

Answer: C) The event at the end of the Triassic Resulted in the extinction of fewer fauna’s then in any other period
Explanation:
Looking at the graph, the event at the end of the Triassic resulted in the smallest dip in the amount of fauna in the graph. This means that this event resulted in the extinction of fewer faunas than any of the other five major events.
Option A is wrong as the event at the end of the Devonian decreased the number of Cambrian fauna.
Option B is wrong as the event at the end of the Cretaceous resulted in a decrease in the Paleozoic fauna.
Option D is wrong because the event that resulted in the Extinction of more fauna’s then in any other period was the event at the end of the Permian.
Answer:
Release or egress
Explanation:
Virus can reproduce only within a host cell, this cycle of infection begins with the <em>attachment</em>, where the virus attaches to a specific receptor site on the host cell, after this comes the<em> entry,</em> in the case of enveloped virus, the envelope can fuse directly with the cell membrane to enter the cell, they can also enter through endocytosis. After entering the cell the virus initiates a <em>replication and assembly </em>mechanism depending on its genome, finally, the last stage of viral replication is the <em>release or egress </em>of the new virions produced in the host organism, some viruses can be released when the host cell dies, but some can leave infected cells by budding through the membrane without directly killing the cell.
