Answer:

The correct answer is the control group or constants.

Explanation:

The control group or the constants are the factors that remain the same in an experiment and also use as the factor to compare the other factors called variables that are subject to change in experiments.

The constant or the control group is the group that is not getting any treatment in or change in the experiments and uses as a standard to evaluates the other factors.

Thus, the correct answer is - the control group or constant.

Answer: 2 - The nucleus of an atom is split apart

Explanation: Any reaction involving the nucleus of an atom is called a nuclear reaction. It is different from ordinary chemical reactions that involve electrons because it involves the release of large amount of energy. Nuclear reactions can be classified as nuclear fission and nuclear fusion.

A nuclear reaction in which a nucleus of an atom is split into two smaller atoms with a release of large amount of energy is called nuclear fission. A nuclear reaction that involves the combination of lighter nuclei of elements to form heavier atoms that are more stable with the release of a large quantity of energy is called nuclear fusion.

Answer:

Bacteriophages are attaching to bacterial cell wall and injecting genetic material.

Explanation:

Bacteriophage:

A bacteriophage (bacteria eater) is a type of virus that infects bacteria. Bacteriophages are composed of genetic material (DNA or RNA) enclosed in a protein shell or capsid.

Following are steps of bacteriophage infection:

  1. Bacteriophage attaches to cell surface receptors on the surface of the bacterium.
  2. Depending upon the type of phage, the bacteriophage either injects its DNA or RNA into the bacterium or enters as a whole. In this image, the bacteriophage T4 is represented which injects its genetic material into the host cell.
  3. The phage's genetic material hijacks the cellular machinery of the host and replicates itself within the host.
  4. After replication, the phages burst open the bacteria cell and are released. This is called the lytic cycle of bacteriophage infection.
  5. In another type of infection cycle, called the lysogenic cycle, the bacteriophage genome gets incorporated into the host genome, known as a prophage. This prophage lies dormant.

* The second step of the infection cycle is pictured here.
