Answer:
through lysogenic cycle
Explanation:
The bacteriophage attaches itself on the bacterial surface. The DNA strand to be replicated is injected into the bacteria by the bacteriophage. The DNA integrates into the bacterial chromosome and becomes a pro-phage.
The bacterial cell proceeds to cell division through budding. The progeny possess the bacteriophage. After complete replication, the virus DNA detaches from the host genome and enters the lytic cycle. The capsid heads assemble on the surface of bacterial cell to package the fully matured viral DNA . The phage produces lytic enzymes that weaken the cell wall of bacteria cell.
Answer:
2. A change occurs in the environment.
4. Poorly adapted individuals have decreased survivorship.
1. Well-adapted individuals leave more offspring than do poorly adapted individuals.
3. Genetic frequencies within the population change.
Explanation:
The natural selection theory was developed by Darwin to explain how evolution occur within a population. The environment is in constant state of changes and always select for organisms that are better adapted to it.
Poorly adapted organisms gradually reduce from the population as a result of decreased survival while well-adapted individuals multiply and contribute more to successive generation.
Well-adapted individuals pass on the adaptive alleles to their offspring, eventually leading to a change in gene frequencies within the population.
Hence, the sequence of events is 2, 4, 1 and 3.

There are a few theories as to what defines our traits to create our personality
According to one such theory, Dan P. McAdams claims our personalities develop in <span>three </span>stages:
<span>Our genes cause genetic mutations forming a 'draft' personality.During our early upbringing, our parents, teachers and friends treat us differently based on our looks and draft personality.Once we are older we then form a narrative of our lives based on our experiences growing up, and make decisions consistent with the character we have created.</span>
So our traits started from slight genetic variances, which effected how we were treated, which then shapes our own self-narrative. So really, our personality is one big story that we tell ourselves, and our childhood was the prologue to that story.
