<h2>Answer:</h2>
The major importance of fingertips receptor is the sense of touch and recognition of things done by this sense.
<h3>Explanation:</h3>
- The first most thing we do with our hand is touch and recognizing things by this touch.
- This importance can be known by supposing that if we don't have these receptors, we will not able to recognize hard, soft even cold and hot.
- As if we encounter something hot which can harm our epidermal layer, our receptors immediately recognize it and pull the hand back by reflex action.
- So the most important receptors of our body are fingertips receptors.
Answer:
In meiosis I, the arrangement of any homologous chromosome along the center plane ( forgot the name for this) is independent of the arrangement of the other homologous chromosomes. There is thus equal probability for the chromosome to be in either of the two daughter cells after meiosis I. This is observed in meiosis 2 metaphase as well where the arrangement of each Sister chromatid about the ‘center plane’ is independent of each other. This independence observed during metaphase of meiosis I and meiosis II allows for chromatids to be in either gamete formed in equal probability, not affecting by other chromatids thus inheritance of one trait is not affected by the inheritance of another trait.
Both protons and neutrons have the highest atomic mass
Structurally speaking, RNA and DNA are different. One clear distinction between the two is that RNA is single stranded, while DNA is double stranded. Another way they differ is found in their nitrogen bases. The four bases for DNA are Adenine, Thymine, Cytosine, and Guanine (think, ATCG). The bases for RNA are the same, except Thymine is replaced with Uracil (think, AUCG).
Another note is that RNA polymerase is unable to detect errors in base pairings, unlike DNA polymerase, but their syntheses are both in the 5’3’ direction. Hopefully this helps you answer this question.
