Answer:
The number of protons in the nucleus of an atom is equal to the atomic number
the number of electrons in a neutral atom is equal to the number of protons
Explanation:
Rutherford reasoned that if Thomson's model was correct then the mass of the atom was spread out throughout the atom. Rutherford was forced to discard the Plum Pudding model and reasoned that the only way the alpha particles could be deflected backwards was if most of the mass in an atom was concentrated in a nucleus.
Answer:
e. All of the above are False.
Explanation:
A tRNA is a transfer RNA that carries amino acid from the cell pool to the mRNA-ribosome complex. The anticodon sequence of tRNA is complementary to the mRNA codons and bind to the respective amino acids. None of the tRNA has anticodon for stop codons and therefore, as soon as the ribosome reaches stop codon, protein translation terminates.
AUG is the initiation codon for protein synthesis and codes for methionine when present at a site other than the start site. The initiation codon is often preceded by an untranslated sequence, also called leader sequence. The ribosome moves along the mRNA in 5' to 3' direction in a GTP dependent manner to facilitate elongation of the polypeptide chain.
Answer:
c. population
Explanation:
A localised group of organisms that belong to the same species is called Population. This can be a local population if the organisms stay at a particular place or a metapopulation if the organisms tend to move from one geographical location to another.
