A nerve is actually a long threadlike
bundle of dendrites that conduct electrical impulses.
<span>Dendrite word derived from the Greek
word ‘dendron’ which means tree. They carry messages in the form of electrical
impulses to cell body, there are also wire like nerves called axon. Sensory
nerves and motor nerves are common types of nerves.</span>
Answer:
Organelle A is chloroplasts
Organelle B is the vacuole
Explanation:
I don’t exactly understand what it means on which one is correct, but I hope this helps you.
Magnesium Phosphate is the answer
<span>It binds itself to the receptors present on the surface of the cell membrane, which activates the enzymes present inside cell. Then It passes through the cell membrane and attaches itself to a receptor protein present in the cytoplasm.
It passes on the signal to the secondary messengers inside the cell, which activate the receptors on the cell membrane.</span>
The right answer is 5.
To answer this question it is sufficient to take the same approach as the one that concluded that each amino acid is equivalent to 3 codons.
We have 17 amino acids, each of which must have at least one unique code (having two nucleotides A and T)
.
it is enough to apply this time to count the number of possible codons to be generated according to the number of nucleotides:
nucleotide set ^ number of nucleotides = number of codons
.
2 ^ 1 = 2 (<17)
2 ^ 2 = 4 (<17)
2 ^ 3 = 8 (<17)
2 ^ 4 = 16 (<17)
2 ^ 5 = 32 (> 17)
So, each amino acid has a codon of 5 nucleotides.
