To determine: The relationship between haploid and diploid chromosome numbers and meiosis and fertilization.
Introduction: The chromosome is the thread-like structure of the

Explanation of Solution
The haploid cells are the cells that consist of a single chromosome set. The diploid cells are the cells that consist of two chromosome sets. Cell division is a process during which a single cell divides into two daughter cells. Mitosis occurs in somatic cells where the diploid number of the chromosome is maintained, whereas meiosis occurs exclusively in gametes. It is known as reductional division because the diploid condition of the cell gets reduced to haploid condition.
Meiosis is a type of cell division in which the chromosomal number is reduced by half, and it creates four haploid cells. Meiosis is necessary for the production of haploid cells for fertilization. During fertilization, haploid cells fuse to form a diploid zygote in which the chromosome number is restored. In plants, meiosis occurs during spore production in flowers or cones. Basically, meiosis counterbalances the fertilization effects by ensuring that the number of chromosomes remains constant from generation to generation.

- 10. Your instructor will give you 2 amino acids during the activity session (video 2-7. A. First color all the polar and non-polar covalent bonds in the R groups of your 2 amino acids using the same colors as in #7. Do not color the bonds in the backbone of each amino acid. B. Next, color where all the hydrogen bonds, hydrophobic interactions and ionic bonds could occur in the R group of each amino acid. Use the same colors as in #7. Do not color the bonds in the backbone of each amino acid. C. Position the two amino acids on the page below in an orientation where the two R groups could bond together. Once you are satisfied, staple or tape the amino acids in place and label the bond that you formed between the two R groups. - Polar covalent Bond - Red - Non polar Covalent boND- yellow - Ionic BonD - PINK Hydrogen Bonn - Purple Hydrophobic interaction-green O=C-N H I.
