Suppose that one virus infects one cell, and 300 minutes later 100 cells are dead (experienced lysis) due to viruses. Which of the following is most likely to describe when lysis occurred for those 100 cells? A. Lysis occurred for zero cells in the first 150 minutes and for all 100 cells in the last 150 minutes.
B. Lysis occurred for 30 cells in the first 150 minutes and for 70 cells in the last 150 minutes.
C. Lysis occurred for 50 cells in the first 150 minutes and for 50 cells in the last 150 minutes.
D. Lysis occurred for 70 cells in the first 150 minutes and for 30 cells in the last 150 minutes.

the oldest known insects are believed to live around 400 millions ago as suggested by the fossil records.   some plants having woody stems also evolved during this time.

after the evolution of insects the first four legged species or the tetrapods evolved in shallow freshwater habitats from the intermediate species approximately 397 million years ago. the tetrapods went on conquering the land giving rise to amphibians, reptiles, mammals and birds.

the major split in tetrapods first occurred 340 million years ago branching off from amphibians.

363 million years ago when the carboniferous period began the insects started roaming on land and taking flights, following which the four limbed tetrapods adapted in the terrestrial habitat.

her affection for her parents makes her an especially sympathetic character.
