Answer:b; exocytosis

Explanation: leukocytes are amoeboid white blood cells, which are involved in immune response .such response included combating foreign bodies like micro organisms which invade the body.they do this by engulfing the micro organisms and digesting them.

Phagocytosis, pinocytosis, receptor mediated endocytosis are the ways in which the cells engulfs the Invaders.

Dmitry_Shevchenko [17]

Answer:

See the answer below

Explanation:

It may seem that the question is incomplete. The complete question reads:

Match each statement to the type of behavior it describes. Jenna published the results of her latest experiment for the public to see. Malcolm altered an experiment to be able reach his desired conclusion. Elena keeps complete records of all her experiment results. Neal shared the results of his field study even though they didn’t support his hypothesis. <em>Put each description to the group it belongs to. 1.Responsible 2.Irresponsible.</em>

<em>To answer the question:</em>

<em>Responsible behavior</em>

  • <em>Jenna published the results of her latest experiment for the public to see.</em>
  • <em>Elena keeps complete records of all her experiment results.</em>
  • <em>Neal shared the results of his field study even though they didn't support his hypothesis.</em>

<em>Irresponsible behavior</em>

  • <em>Malcolm altered an experiment to be able to reach his desired conclusion</em>

Responsible behaviors are those that support responsible scientific practices and do not jeopardize the objective nature of research. Every data during experiments must be well kept and after thorough analysis, results must be published fro the public to see irrespective of whether it agrees or disagrees with the original hypothesis.

Altering an experiment in order to achieve the desired result is grossly irresponsible, as this eliminates the objectivity that should be the main goal of every experiment. Bias must be eliminated from every scientific experiment.

The slow release of the bacteriophage progeny from a bacterial host cell causes bacterial cell lysis and further kills the host cell which is the bacteria, this results to the liberation of progeny viruses which then infect new bacterial cells.

Only a type of bacteriophage called the filamentous bacteriophage reproduces without killing the bacterial host cell.  The filamentous phages infect majorly gram negative bacteria.
