1. Define phagocytes and explain their role in the immune system.
2. What are antibodies? How are they made? What are their job in the immune system?

1) Phagocytes are cells that protect the body by ingesting harmful foreign particles, bacteria, and dead or dying cells.Phagocytes circulate throughout the body, looking for potential threats, like bacteria and viruses, to engulf and destroy.

2)An antibody, also known as an immunoglobulin, is a large, Y-shaped protein produced mainly by plasma cells that is used by the immune system to neutralize pathogens such as pathogenic bacteria and viruses.Antibodies are produced by specialized white blood cells called B lymphocytes (or B cells). When an antigen binds to the B-cell surface, it stimulates the B cell to divide and mature into a group of identical cells called a clone.

an organism's phenotype is the  form of a trait  that it  displays. for  flowercolor, a pea  plant  can  display  a phenotype of purple or white flowers. an organism's  genotype  is the alleles of a gene it contains. based on his data, mendel concluded that a phenotype can be  determined  by more than one  genotype.

a- multicellular

b-eukaryotic

c-no cell wall

d-heterotrophic

e-autotrophic
