What structures pull chromosomes apart? The movement of chromosomes is facilitated by a structure called the mitotic spindle, which consists of microtubules and associated proteins. Spindles extend from centrioles on each of the two sides (or poles) of the cell, attach to the chromosomes and align them, and pull the sister chromatids apart. What cells […]
Does boiling point increase across a period?
Does boiling point increase across a period? Melting and boiling points increase across the three metals because of the increasing strength of their metallic bonds. The number of electrons which each atom can contribute to the delocalized “sea of electrons” increases. The atoms also get smaller and have more protons as you go from sodium […]
What is the uses of technology?
What is the uses of technology? Technology has evolved and shaped our workplaces in many ways, through the adoption of tools like the internet and email for communications, word processing, spreadsheets and presentations for office productivity, electronic databases for record keeping, and robots and artificial intelligence for automation. What does technology mean for you? Technology […]
What happens if you can see yourself in a black mirror?
What happens if you can see yourself in a black mirror? If you’re suddenly feeling more of a distance from the image in the mirror and photos, it’s likely that you’ve had a major life change recently and your filter through which you view yourself has changed. In your eyes it’s like literally seeing a […]
Why does the inner core of Earth remain solid even though it is very hot?
What is the purpose of the iodine clock reaction?
What is the purpose of the iodine clock reaction? The “clock reaction” is a reaction famous for its dramatic colorless-to-blue color change, and is often used in chemistry courses to explore the rate at which reactions take place. The color change occurs when I2 reacts with starch to form a dark blue iodine/starch complex. Why […]

Why do most students prefer last minute? Why students study last minute Procrastination and the perception that they perform better under pressure and cramming “just works better for them”, was also among the top reasons for last-minute study habits. Is it good to study last minute? The last 24 hours before an exam can be […]
Would a propeller work in space?
Would a propeller work in space? Turbine engines and propellers use air from the atmosphere as the working fluid, but rockets use the combustion exhaust gases. In outer space there is no atmosphere so turbines and propellers can not work there. This explains why a rocket works in space but a turbine engine or a […]
What is the minimum transmission bandwidth?
What is the minimum transmission bandwidth? Minimum Transmission Bandwidth (Using Ideal Nyquist Pulses) As seen the bandwidth required is (Rb)/2 (∵Rb =1/Tb) for the Nyquist pulse shown above. It is the peculiar scheme of overlapping signals that results in minimum transmission bandwidth. How many signaling levels are needed? How many signal levels do we need? […]
