AI Thread Summary
Chromosomes can be accurately counted during the metaphase stage of mitosis due to their alignment along the metaphase plate, which makes them easily visible and distinguishable. In this phase, chromosomes are condensed and organized, allowing for clear identification and counting. Other phases, such as prophase and anaphase, present challenges due to chromosomes being less organized or in motion, making counting difficult. Karyotype analysis often utilizes metaphase images for this reason. Understanding the structural arrangement of chromosomes in metaphase facilitates accurate chromosome counting.

What stage of mitosis can chromosomes be counted and why?

Is this a homework question?

Look at how the chromosomes are arranged during various phases of mitosis. Then look at some karyotype photos. What would be convenient about the particular phase in question concerning chromosome structure and placement? Why do the other phases present greater difficulty?

Thread 'Confusion regarding a chemical kinetics problem'

TL;DR Summary: cannot find out error in solution proposed. [![question with rate laws][1]][1] Now the rate law for the reaction (i.e reaction rate) can be written as: $$ R= k[N_2O_5] $$ my main question is, WHAT is this reaction equal to? what I mean here is, whether $$k[N_2O_5]= -d[N_2O_5]/dt$$ or is it $$k[N_2O_5]= -1/2 \frac{d}{dt} [N_2O_5] $$ ? The latter seems to be more apt, as the reaction rate must be -1/2 (disappearance rate of N2O5), which adheres to the stoichiometry of the...

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
