Asexual reproduction produces genetically identical offspring and sexual reproduction creates variation in the offspring. When the environment changes and it affects the asexual offspring it will affect all identical copies whereas since the sexual offspring have more variation, they are more likely to survive.
Answer:
The limbic system
Explanation:
Limbic system is also named as paleomammalian cortex. Limbic system is located on both sides of thalamus beneath the cerebrum temporal lobe.
The limbic system controls the different functions like behavior, long term memory and emotion. This system is also referred as emotional brain as it controls the emotional state of an organism.
Thus, the correct answer is option (a)
Answer:
- The mRNA code for each type of amino acid is a sequence of <u>three</u> nucleotides, called a codon.
- mRNA codon that codes for the amino acid Phe es UUU.
Explanation:
The messenger RNA (mRNA) has in its structure sequences of 4 nucleotides adenine, uracil, guanine and cytosine. The possible combinations of these nucleotides to group into triplets is 64 codons to form 20 amino acids, from which it can be concluded:
- <em>An amino acid can be encoded by more than one codon.
</em>
- <em>From these combinations the three STOP codons are obtained.
</em>
A mRNA codon is a sequence of three nucleotides that serves to encode an amino acid.
Phenylalanine (Phe), according to the image, is formed with the UUU codon.
