What is a simple experiment that can be used in order to observe the loss of synchronous division in an organism after the third cellular division?
Methods
1) cell density count using cell plate technique- different stage cells having different division capabilities and hence cells. no. also varies which can be detected easily.
2) FACS - flouroscence assisted cell sorting - this techniques also based on detection of different no. of cells using diferently lebeled antibodies with specific color.
3) Can measure specific activity of house keeping or constitutive gene whose no. will keep on changing as no. of cells changes.
4) spectrophotometer technique to measure the cell density based on optical density of cells.
Hope it's clear..thanks

Compare the effectiveness of molecular diffusion in a simple organism (unicellular) versus a multi-cellular organism. What are the limitations of diffusion and how do multi-cellular organisms overcome these problems?
Describe an example of osmosis that we can observe in real life. Explain what is happening at the cellular level, including what is moving across the cell membranes and in which direction (in or out of the cells)?
When Sodium yellow light (λ = 5890 A0 ) is used in double-slit experiment, the first-order maximum is observed at a distance of 0.05cm from the central maximum. When the light is placed by one of an unknown wavelength, the third-order maximum occurs at 0.065 cm. what is the wavelength of this later light?
Sunlight is used in a double-slit interference experiment. The fourth-order maximum for a wavelength of 460 nm occurs at an angle of θ = 90°. Thus, it is on the verge of being eliminated from the pattern because θ cannot exceed 90° in Eq. 35-14. (a) What least wavelength in the visible range (400 nm to 700 nm) are not present in the third-order maxima? To eliminate all of the visible light in the fourth-order maximum, (b) should the slit...
What kind of experiment can be done in order to figure out whether the gene is autonomous or non-autonomous? Please tell the process and the principle of the experiment .
I did a simple experiment regarding osmosis and the rate of diffusion along a concentration gradient. I practiced changes of weight of dialysis bags used as cellular models. My last measurement of Bag A, which contained 10 ml of 1% sucrose in a beaker of 10%sucrose and water, ended up having a total weight of 28.1 grams after 60 minutes. This was a -0.5 change in weight from the 45 minute interval where I calculated the weight. I am just...
In a Young's double slit experiment, you observe a series of bright and dark fringes, the bright fringe to the left of central bright fringe is 1 cm away from the central bright fringe. The laser used in the experiment is 600 nm and the distance between the double slit where the pattern is projected is 1 m. What is the distance between the two slits?
can
someone explain these concepts in full detail?
Understand cellular respiration (what 3 main steps are used and in what order, what is produced and used at each step, what electron shuttles are utilized, where does it happen, what types of cells perform it, etc.) · Know the chemical equation of cellular respiration Understand fermentation (how is it different than cellular respiration, how it is initiated, and why it is utilized) . Understand photorespiration (how it is different from photosynthesis,...
what is electrolysis and what is the overall reaction in this
experiment? write out the half reactions occurring at each
electrode (assuming you are electroplating copper.
Electroplating is the process by which a thin layer of metal is deposited on an electrically conducting surface. In electroplating, the metal to be plated is used as the anode and the electrolytic solution contains an ion derived from that metal. In this experiment, the copper electrode will be used in a solution of...
