Answer:

BENEFITS:

The Descriptive investigation is used to describe a natural system when nothing or very little is known about the system. Like observing a new specimen in the microscope and describing it by observing the specimen.

A comparative analysis is used to compare two or more variable in nature by collecting data like observing the different colors of the rocks. It provides the data to show the similarity and dissimilarity of the population.

The Experimental investigation is used where experiments are performed to test and answer the scientific questions. The advantage is that data can be used as evidence for future research.

LIMITATIONS:

<u>descriptive  method  of  investigation </u>

It cannot be used to correct variable or be used to determine causes and  effect  of  the  problem

<u>experimental  method  of  investigation </u>

It might create an artificial situation that do not always represent the real  life situation

<u>comparative  method  of  investigation </u>

It  is not easy to control other variables that might influence the study

What is (are) the role(s) of complement proteins in the immune response?
AlexFokin [52]


The correct answers are I and  IV

There are three main effects  of complement :

1. Lysis of cells such as bacteria and tumor cells.

2. Generation of mediators that participate in inflammation and attract neutrophils to the site of infection, an event called chemotaxis.

3. Opsonization i.e. enhancement of phagocytosis.

Lysis of pathogens by complement involves the insertion of  a special substance called the membrane attack complex into the cell membrane of the pathogen which disrupts or punctures the membrane as  a result of which water  and electrolytes enter the pathogen and it dies. 

Generation of mediators known as C5a and C567  complex attract neutrophils.
