Answer:
Infection of a bacterium by a bacteriophage with subsequent production of more phage particles and lysis, or dissolution, of the cell. The viruses responsible are commonly called virulent phages. Lytic infection is one of the two major bacteriophage–bacterium relationships.
Lysogeny, or the lysogenic cycle, is one of two cycles of viral reproduction. Lysogeny is characterized by integration of the bacteriophage nucleic acid into the host bacterium's genome or formation of a circular replicon in the bacterial cytoplasm.

Answer: The correct answer is -
D. Eukarya has similar evolutionary traits to archaea.
A phylogenetic tree (also known as evolutionary tree) is a diagrammatic representation (in the form of branch diagram) showing the evolutionary relationships among various organisms. It is constructed on the basis of similarities or differences in the genetic or physical characteristics of various species.
In the given phylogenetic tree, archaea domain shows more similarities to the domain eukarya as it has descended after the domain bacteria.
Thus, option D) is the right answer.
Research has demonstrated that neural stem cells have an impaired ability to differentiate into functional neurons when subjected to ethanol. They found out that treating cultured neural system impairs their ability to differentiate in functioning neurons. With this impairment it seems to be united with aberrant, dense methylation and loci which are active in normal tissue.
D is correct. Newton's first law of motion states that an object in motion stays in motion. The orange is moving and then the tray stops making the orange move forward because of inertia. Hope this helps! ;)
Answer;
-Allele frequency change
In single-gene traits, natural selection can lead to allele frequency change.
Explanation;
-Allele frequencies can change over time within a single population, and frequently differ between populations. This change is due to four different processes: mutation, selection (natural and artificial), gene flow and genetic drift.
-Random forces lead to genetic drift. Sometimes, there can be random fluctuations in the numbers of alleles in a population. These changes in relative allele frequency, called genetic drift, can either increase or decrease by chance over time.
