Inulin is a polymer of

Options:
A amino acids
B glucose
C fructose
D nucleotides

The correct answer is:
fructose

Solution:
Carbohydrates are hydrates of carbon. These are classified as Monosaccharides, Oligosaccharides and Polysaccharides depending on number of sugar units. Polysaccharides contain more than nine sugar units. These are further classified as Homosaccharides if all the sugar units are same and Heterosaccharides if more than one type of sugar unit is seen. Examples of Homosaccharides are Cellulose, Starch, Glycogen and Inulin etc. Inulin is the only homopolysaccharide which is made up of many fructose units. This sugar is used to assess kidney function.

B Embryo of 32 cell stage
C Sperm and ovum
D Either zygote or early embryo upto 8 cell stage

The correct answer is:
Either zygote or early embryo upto 8 cell stage

Solution:
The baby produced by conceiving in a culture dish and nursing in the uterus is called a test tube baby. This method involves in vitro fertilization (IVF), i.e., fertilization of male and female gamete outside the body in almost similar conditions as that in the body followed by embryo transfer (ET). Either zygote or early embryo up to 8 blastomeres is transferred into the Fallopian tube (ZIFT - Zygote Intra Fallopian Transfer) to complete its further development. If the embryo is with more than 8 blastomeres, it is transferred into the uterus (IUT - Intra Uterine Transfer) to complete its further development.
