The answer is 'Cambrian' explosion. This took place approximately 541 million years ago. 'Explosion' refers to the evolution of a large range of new major animal phyla. Scientists know this by the large number of diverse fossils from this period. Prior to this period, organisms were single-celled, but over the Cambrian Explosion, lasting about 80 million years, life forms diversified rapidly to resemble the life forms existing today.
Another difference would be that DNA contains the 5 carbon sugar deoxyribose while RNA usually contains the 5 carbon sugar of ribose. One differs from the other, as ribose has an additional hydroxyl group bonded to one of the carbon atoms, where as deoxyribose does not.
Answer:
e, both A and C
Explanation:
The lytic life cycle ends when the virus load is expelled from the host cell. But, to be released, the virus have to escape from the host cell's plastic membrane, usually by changing the osmotic change, and making it explode.
This releases the viruses into the extracellular matrix, allowing them to infect other tissue cells.
Answer with Explanation:
Hydrogen peroxide is considered<em> "unstable,"</em> thus, storing it in the refrigerator provides two advantages:
1. It slows down thermal decomposition.
- The rate of decomposition slows down when the temperature is lowered. It increases when the temperature rises.
2. It prevents photolytic decomposition.
- Photolytic decomposition happens when hydrogen peroxide is exposed to sunlight or bright light. It therefore increases the rate of reaction. Therefore, hydrogen peroxide should be stored in a <em>cool and dark place</em>, such as the refrigerator.
