Expert Solution & Answer

Summary Introduction

To analyze:

The structures seen in the movie on time lapse of conceptus starting at day 3.

Introduction:

Upon conception, there are a series of events that follow one after the other from a unicellular zygote to multicellular embryo.

Explanation of Solution

In the video on the time-lapse of conceptus starting at day 3, the first structure seen is the morula. The morula is a ball of cells that resembles a berry. It is formed from repeated division of zygote to first form two blastomeres followed by more divisions to generate this ball of cells called morula.

The blastocoel first appears at a time elapse of 22 seconds of the video. At this point it is attached to the zona pellucida. At the end of the video the blastocoel 'hatches' from the matrix, that surrounds it. It can now head its way to implant into the walls of the uterus.

Conclusion

The morula divides to form the blastocoel that hatches out of the zona pellucida to implant into the uterus.

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).
