To draw: A survivorship curve for a species with high rates of predation in early life and one for a species with high mortality late in life and the type of survivorship these species display. Introduction: The survivorship is the proportion of individuals from the initial cohort (a group of individuals born at a given time) that survive to each successive stage of life cycle. The age of population differs at which they experience the most mortality. In many species, offspring are produced but high mortality occurs at early in life that is only some survived to reproductive age. In other species, mortality rate is highest in older individuals and in some other species, the mortality occurs late in life or mortality occurs with equal frequency at all ages.

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.

Find the dental formula and enter it in the following format: I3/3 C1/1 P4/4 M2/3 = 42 (this is not the correct number, just the correct format) Please be aware: the upper jaw is intact (all teeth are present). The bottom jaw/mandible is not intact. The front teeth should include 6 total rectangular teeth (3 on each side) and 2 total large triangular teeth (1 on each side).
