A particular viral genome can replicate in 8 hours. If you start with 55,000 copies of this genome, about how many copies would
deff fn [24]

If a viral genome can replicate in 8 hours and the starting copies is 55,000, the number of copies after 48 hours would be 3,360,000 copies

<h3>Replication rates</h3>

The starting number is 55,000 and replication happens every 8 hours.

Starting from 0 hours, the genome would 55,000

After 8 hours = 55,000 x 2 = 110,000 copies

After 16 hours = 110,000 2 = 220,000 copies

After 24 hours = 220,000 x 2 = 420,000 copies

After 32 hours = 420,000 x 2 = 840,000 copies

After 40 hours = 840,000 2 = 1,680,000 copies

After 48 hours = 1,680,000 x 2 = 3,360,000 copies

Which of the following materials is not part of every chemical reaction?
Sladkaya [172]

Answer:

The correct answer is C. gases.

Chemical reaction is the process by which one or more substances are converted into different substance or substances.

The substances which undergo chemical reaction are called as reactants while the substances which are produced by the reaction are called as products. During chemical reaction, chemical bonds of substrates undergo breaking and formation process to form an entire new product which may have same or different physical and chemical properties as compared to substrates.

Energy is either used or released during the chemical reaction. When the energy is used, it is termed as endothermic reaction but when the energy is produced by the reaction, it is termed as exothermic reaction.

Lastly, gases may or may not participate in a chemical reaction.

What experimental evidence is there for the origin of life hypotheses?
ololo11 [35]

"The earliest evidence of life on Earth comes from fossils discovered in Western Australia that date back to about 3.5 billion years ago. These fossils are of structures known as stromatolites, which are, in many cases, formed by the growth of layer upon layer of single-celled microbes, such as cyanobacteria. (Stromatolites are also made by present-day microbes, not just prehistoric ones.)

The earliest fossils of microbes themselves, rather than just their by-products, preserve the remains of what scientists think are sulfur-metabolizing bacteria. The fossils also come from Australia and date to about 3.4 billion years ago

Bacteria are relatively complex, suggesting that life probably began a good deal earlier than 3.5 billion years ago. However, the lack of earlier fossil evidence makes pinpointing the time of life’s origin difficult (if not impossible)."
