A molecular model is a three dimensional representation of a molecule that aids conceptualization of the actual nature of the molecule.

The correct answer is option B: one blue sphere and three white spheres

A molecular model helps us to see something close to what a molecule actually looks like in a three dimensional way.

The essence of molecular models is to aid conceptualization of details about arrangement of atoms in a molecule.

Since nitrogen is represented with blue balls and hydrogen is represented with white balls, it follows that a properly prepared model consists of one blue sphere and three white spheres.

25.Nitrogenous wastes in the body tend to form toxic ammonia, which must be excreted. Mammals such as humans excrete urea, while birds, reptiles, and some terrestrial invertebrates produce uric acid as waste. Uricothelic organisms tend to excrete uric acid waste in the form of a white paste or powder.

34.The excretory system removes cellular wastes and helps maintain the salt-water balance in an organism. In providing these functions, excretion contributes to the body's homeostasis, the maintenance of constancy of the internal environment. When cells break down proteins, they produce nitrogenous wastes, such as urea

Yes. Absolutely. Without heart, no one can live. It helps in pumping of oxygen rich blood to all body cells and tissues. It also helps in transportation of various materials like potassium, sodium, calcium etc. in our body. The main function is that it helps in excretion of wastes.

Since blood is liquid and heart pumps it, the waste materials like CO2, gets diffused and becomes impure blood. Then it is taken to lungs for purification and again reused.

So, heart actually helps us indirectly in many ways.
