Answer: d- because a model is never exactly the same as the thing it represents
Answer:
A cell that results from the fusion of sperm and ovum is called a zygote. The process of fusion of sperm and ovum is called fertilization.
Answer:
The correct answer is - solubility
Explanation:
Solubility is the nature of the material that is a chemical property of that specific solute ability to dissolved in a solvent. The ability of solute or material in a solvent or liquid is measured by the term of the maximum amount of that material dissolved in the liquid at equilibrium.
Sugar and water is a great example of solubility. When sugar is missed in the water it dissolved in water and disappear in the water here sugar is solute and water is solvent.
Thus, the correct answer is - solubility.

Explanation:
Pepetidoglycans are the structural polymers which make up the cell walls of most bacteria.
It consists of the macromolecule, glycan chains, which are repeating N-acetylmuramic acid and N-acetylglucosamine residues. These glycan chains combine or cross-link with peptide side chains (proteins) to form a mesh-like layer outside the plasma membrane of most bacteria.
Peptidoglycan is the major structural component and the basic unit of the bacterial cell wall and provides protection to the cytoplasmic membrane, mechanical rigidity and also regulates the passage of fluid, amino acids, sugar and ions, in and out of the cell.
