Immunoglobulins are produced by D. plasma cells, a type of leukocyte. They are produced in response to the foreign bodies that enter the body. The immunoglobulins are also known as antibodies. The immune response of the antibodies is quite complex and highly specific to the type of antigen it binds to. There are five types of immunoglobulins in the mammals, they are IgA, IgD, IgE, IgG and IgM.
Answer:
recessive gene
Explanation:
mainly masked by thee dominant gene eg Tt where T is dominant over t,,,there t is recessive..
Answer:
1. Aspartate and PRPP
2. Aspartate, glycine and glutamine
Explanation:
Aspartate is a precursor in both the synthesis of purine and pyrimidine. It aids in the formation of Carbamoyl Aspartate in pyrimidine synthesis while in purine, it contributes nitrogen 1 to the purine ring. PRPP is needed in the activation of ribose sugar in the purine nucleotide synthesis, while in that of pyrimidine, it aids in the conversion of orotate to OMP by adding phosphate group to orotate.
Aspartate, glycine and glutamine are precursors in the de novo synthesis of purine nucleotides. Aspartate contribts nitrogen 1, glycine cotributes C4, C5 and nitrogen 7 while glutamine contributes N3 and N9.

The 3 groups of fish are:
Jawless, cartilaginous and bony fishes.
Jawless fish were one of the first vertebrates in this world. These fish have no scales, and instead are made of cartilage. Also, like the name says, they have no jaws and no fins. Some jawless fish include hagfishes and lamprey's. These are the only species alive today.
Cartilaginous fish include sharks and rays. Their skeletons are made out of cartilage, similar to the jawless fish. But, they do have jaws and fins. Their bodies are covered with pointy teeth-like scales, which makes their skin rougher than sandpaper.
Bony fish have scales that overlap each other, and instead of cartilage, they have bones like other animals. These scales are made from the same substance as your fingernail. The slimy substance mucus covers the fish (it's in your throat and nose as well), and protects it from other dangerous things. Bony fish are basically 95% of all fish.
