First eliminate choices C and D since they both mention that fact 1 is crossing over ( which is also referred to as genetic recombination) . So you're left with A and B and the correct answer is B .
The right option is lateral
corticospinal tract
The lateral corticospinal tract functions
in the control of distal muscles such as those of the limbs and the trunk. About
90% of the fibers that travel in the corticospinal tract are found in the
lateral corticospinal tract which makes it the main component of the corticospinal
tract.
Answer: The correct answer would be B
In your cells, cellular respiration happens in a special organelle called the mitochondrion. But as mentioned, prokaryotic organisms don't have organelles. Rather than taking place in the mitochondrion, cellular respiration happens either in the cytoplasm or across the plasma membrane of the cell.
