Phagocytosis is a process where cells can engulf bacteria or food.
<h3>What is phagocytosis?</h3>
Phagocytosis is a process in which cells such as macrophages surround and engulf some type of substance that the body wants to eliminate. Phagocytosis is a type of <em>endocytoses</em>. It is a process that the immune system uses to eliminate pathogens or cellular debris, finishing the material being digested by the cell, seen in processes such as infection.
We also see it in <em>apoptosis</em>, where the macrophages are going to ingest the remains of the apoptotic cell for the elimination of their cellular remains.
Therefore, we can confirm that phagocytosis is a process where cells can engulf bacteria or food.

Parasitism can be defined
as a relationship between species in which one organism (parasite) lives on or
in another organism which is the host, causing it some harm without immediately

biological interactions.
<u>Answer</u>: linear diameter
<em>The linear diameter of moon is 3754 km.
</em>
<u>Explanation:</u>
<em>Moon is the only satellite of earth. It doesn’t produce light on its own but reflects the light of sun and appears lighted up. </em>The diameter of moon can be found out using parallax method.
In parallax method moon is observed through a telescope from a point on earth the angle θ between the <em>diameter of the moon</em> and this point on earth is measured. This angle is mathematically equal to the ratio of diameter D of moon and the <em>shortest distance S between moon and earth.</em>
<em>Thus diameter of moon can be calculated by finding the product of the distance between moon and earth and the angle.
