Answer:process of science
Explanation:
<span>Cocaine Preparations
-Coca leaves --> Coca Paste (60% pure): Not water soluble, so you can't inject it into the bloodstream -- you need an additional chemical step to turn the paste into crystal powder that can be injected or snorted
-Coca --> Cocaine Hydrochloride (99% pure): Doesn't hold up very well to heat, so you can't smoke cocaine hydrochloride
-Cocaine Hydrochloride (99% pure) --> Free-Base Cocaine or Crack Cocaine:
-Reconvert cocaine hydrochloride back to base state by removing hydrochloride from cocaine (that's why it's called free-base cocaine)
-Crack cocaine is a crystallized form, mixture of cocaine and baking soda
-75% pure
-Can be used at lower doses and is much cheaper than cocaine
-Can be smoked</span>
Answer:
Benefits:
In a lab, scientists can control the conditions according to their research and study. This allows them to focus on a single perspective.
On the other hand, in a natural setting there are complex interactions due to which focusing on a single attribute can be difficult.
Drawbacks:
Ina laboratory experiment, we cannot control every variable which might be having an effect on our concerned subject as compared to a natural setting. This is because lab experiments are performed in a controlled experiment. Hence, there might be difference of results in a lab experiment and nature.
Answer:
lysogenic
Explanation:
Phages can generate the lytic cycle or the lysogenic cycle, although very few are able to carry out both. If lysis is carried out, lysogeny cannot be carried out and vice versa. In the lytic cycle, phage host cells are lysed (destroyed) after replication and encapsulation of viral particles, so that new viruses are free to carry out a new infection.
On the contrary, in the lysogenic cycle there is no immediate lysis of the cell. The phage genome can be integrated into the chromosomal DNA of the host bacterium, replicating at the same time as the bacterium does, or it can remain stable in the form of a plasmid, independently replicating bacterial replication. In any case, the phage genome will be transmitted to the entire progeny of the originally infected bacteria. The phage is thus in a state of latency until the conditions of the environment are deteriorated: decrease of nutrients, increase of mutagenic agents, etc. At this time, endogenous phage or phage are activated and give rise to the lytic cycle that ends with cell lysis.
