Sir for 37, why wouldn't it be C, seeing as the motor neurone is the one that actually delivers the impulse to the effector?

@earlytocxc Месяц назад

The wording of the question makes 37 a poorly designed question. B is literally the relay neuron, or they acting as motor neuron is separate from the muscle. So it can be C depends on how you interpret the question. Great catch.

THANKS SIR OMG

sir for number 4, it's not supposed to be B?

@earlytocxc 3 месяца назад

You are correct B is NOT the answer, the correct answer is D (as shown in the video)

Sir for 51, if the 3rd diagram was the first, wouldnt it show 4 chromatids and 2 chromosomes, instead of just 2 chromatids, and since it does show just 2 could it then be referring to after cytokinesis looking at one of the produced daughter cells

@mika.shatani Месяц назад

if it was after cytokinesis there would be two daughter cells but there is only one. yes normally there would be 4 chromatids instead of just two but based on this question the third diagram would be prophase because of the splinder fibers beginning to form.
