Plzz help will give brainiest. What pair of chromosomes do not go through crossover
KengaRu [80]

Answer:

The Y chromosome do not go through crossover

Explanation:

Typically, genes from the mother and father are shuffled -- or, "cross over" -- to produce a genetic combination unique to each offspring. But the Y chromosome does not undergo crossing over, and, as a result, its genes tend to degenerate, while repetitive DNA sequences accumulate. Each chromosome is made up of DNA.

Explain why the resistance of the current path through the extracellular fluid is much smaller than the resistance of the curren
vodka [1.7K]

Answer:

The correct answer is - the large cross-sectional area and greater length of the cytoplasmic core get less resistance than the smaller cross-sectional area.

Explanation:

The greater length and the large cross-sectional area of the cytoplasmic path or core get less resistance than the resistance of the current path which is the small cross-sectional area of axoplasm. This leads it to greater resistance than the resistance of the current path through the extracellular fluid.

Other than this there is also an unequal distribution of the ions that leads to the increase in potential difference as higher Na+ ions present in cytoplasm and high amount of K+ ion present in axoplasm.
