This causes Oxygens and Hydrogens from <em>different</em> water molecules to attract each other as well! Most importantly, however, hydrogen bonds allow water molecules to have its cohesive properties, which allows it to do many of things water is essential for. Hint: capillary action.

Spontaneous miscarriage in the first trimester is related to Chromosomal defects in the fetus. An estimated 15 to 20 percent of known pregnancies end in miscarriage, the loss of a pregnancy before the 20th week. Upto 70 percent of first-trimester miscarriages, and 20 percent of second-trimester miscarriages, are caused by chromosomal anomalies/abnormalities in the fertilized egg.

Answer:
The primary function of glucose molecules is to provide energy for cell activities.
Explanation:
Glucose can best be described as carbohydrate which serves best as a primary fuel. Our body cells carry out a wide number of metabolic as well as biological functions. Glucose serves as the main energy derivation molecule for the accomplishment of these biological and metabolic functions. Every cell present in the body acquires the capability of using glucose as energy molecule.
Glucose is broken down by complex biological reactions into ATP which is the energy source for many cellular activities.
