The following are steps in the cell-mediated immune response. what is the correct sequence for these steps?
a) several cycles of mitosis occur.
b) antigen is engulfed and presented by a macrophage.
c) cytotoxic t cells migrate to focus of infection.
d) t cells with specific receptors recognize the antigen.
e) t cells differentiate into cytotoxic t cells or t memory cells.
f) cytotoxic t cells release perforin and/or lymphotoxin.

Steps in correct sequence:  

B) – D) – A) – E) –C) – F)  

Explanation:

Cell-mediated immunity is a particular adaptive immune response. This type of immune response fight against intracellular infections such as viruses, some bacteria, fungi, and Plasmodium. Cell- mediated immune response is activated by TH1 cells.

Steps in correct sequence given below:

B) Antigen is engulfed and presented by a macrophage.  

D) T cells with specific receptors recognize the antigen.  

A) Several cycles of mitosis occur.  

E) T cells differentiate into cytotoxic T cells or T memory cells.  

C) Cytotoxic T cells migrate to focus of infection.  

F) Cytotoxic T cells release perforin and/or lymphotoxin.

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.
