Explanation:
<u>Reason that Drastic Change in weather may cause mass extinction</u>
Weather plays an important role in the survivability & the growth/diminish of the population. For example, animals that need large amounts/bodies of water (for example fishes), will not survive when the area is hit with a heat wave & drought, which would cause fishes to surface, and die.
<u>Reason that Geological change would play a large role in mass extinctions</u>
While the Geography is constantly changing, large abrupt changes would cause a upheaval and may upset the population, leading to a depletion of resources or even a sudden destruction of part/all of the population. For example, an earthquake may kill large amounts of animals, and the destruction of the greenery in the area may severely limit the amount of food/decrease the primary consumer's populations, leading to a starvation.

Answer:
Sigma factors bind to the promoter region of a particular gene and facilitating the binding of RNA Polymerase to the promoter region (formation of the RNA polymerase holoenzyme complex) in order initiate transcription of the gene.
Put simply - Helps RNA Polymerase do it's job.
The scientist that discovered cells by observing cork with a homemade microscope would be Robert Hooke.
The answer is sexual reproduction in which the creation of offspring by fertilization consisting 2 haploid gametes come together to form a diploid zygote with a new genetic combination. The main difference between sexual and asexual reproduction is that asexual reproduction results in a genetically identical offspring whereas sexual reproduction results in a unique offspring in which offspring with a new genetic combination.
