Yes, the Paris attack was tragic. I suspect these attacks will continue in the future, until humanity learns to share resources and respects each others' cultural differences.

I do have projects similar to Janson et al, 2007 Cell to propose to you.

Spindle dynamics in meiosis I & II have not been well characterized (see attached movie). During meiosis, two haploid (1N) cells mate/fuse and become one large diploid (2N) cell. This diploid zygote duplicates its DNA (4N) and forms one meiosis I spindle to segregate the DNA into 2 X 2N, then it forms simultaneously 2 meiosis II spindles to segregate the DNA into 4 X 1N haploid spores. These spores will become 4 new (1N) baby cells.

There are fundamental questions which we can address:

1. How and why meiosis I spindle is two times longer compared to meiosis II spindles ? In principle, the cell size has not changed, and the motors and MAPs which organize the spindles are the same. By analyzing meiosis I & II spindles, and making mutations of motors and MAPs known to regulate spindle mechanics, we will learn the differences between meiosis I and II. …show more content…
Related to above, how does the concept of organelle/spindle "scaling" works in the context of one cell ? It is known in different organisms that spindle length scale with cell length, i.e., small cells have small spindles, and large cells have large spindles. Here we have 2 different spindle lengths in one size cell. This question is more abstract and conceptual. But the system may be useful to dissect and define this concept, both experimentally and

From the annealing part of lab, I was expose to heating up brass at three different temperatures and measuring the harness value of each sample under different time intervals. The result show reduction trend in hardness value of material as annealing time increase. This makes sense…

1. What questions (hypotheses) are addressed in the paper? Look in the Abstract. Can we calculate the equilibrium for the entire MgO-SiO2 range? If so, can we use these values to create a phase diagram for these minerals? What minerals are present in this composition range? 2. What are the main conclusions of the paper? Look in the Abstract and Conclusions. The main conclusions of the paper are that the most accurate part of the MgO-SiO2 range to calculate equilibrium is the middle compositions…

It causes the bext axon to open up its gates 5. What is the role of the voltage-gated sodium channels for producing an action potential? The gated channels allow the sodium into the axon which causes the membrane potential above the threshold 6. What is the role of the voltage-gated potassium channels? Potassium gates close after sodium gates close too 7. What would happen if the voltage gated sodium and potassium channels opened a. at the same…

three quarters did not like the outside preparation. The one quarter liked the outside preparation because they felt that the research gave them more background about the lab they were doing. They could spend the time researching online exactly what the experiment wanted us to do. The other three quarters of the group felt that the labs were too difficult, and that the descriptions on canvas didn't provide enough information to create a procedure. They would prefer to have a procedure given to them. New…

In this lab exercise, my team and I were assigned to design and build a bridge out of masking tape and 36 full pieces of spaghetti noodle. The main objective however is for it to hold a single copper penny out as far away from the edge of the lab table as possible. However, my team and I had to use the engineering design process to design, build, and test the structure. During the construction phase, the team helped each other out numerous of time and we each tried to work on different parts of the…

The balance of protons and neutrons in a nucleus determines whether it will be stable or unstable. If the nucleus has too many protons or too many neutrons this will upset the balance. The upset of the balance disrupts the strong nuclear forces and the nucleus becomes unstable. The graph below demonstrates the neutron to proton ratio: From the graph shown many stable nuclei have an equal number of protons to neutrons, these are elements in the lighter sections of the periodic table. The heavier…

the levels of Cobalt in MoP and MoM over two years. MoP shows not a lot of increase while MoM shows extensive growth in the amounts of Cobalt. I suppose I would agree. Because this was compared to another study which resulted in similar results. 6. Summarize figure 4 in your own words. Do you agree with the conclusions drawn? Why or why not? Figure 4 shows the levels of Ti after two years. Both MoP and MoM experienced minimal rises in the levels of Ti after one year and two years, even though…
