The snakes have evolved resistance to the blowfish poison, tetrodotoxin (TTX), by preying on rough-skinned newts, which also secrete the toxin. Some newts are so poisonous that they harbor enough TTX to kill a roomful of adult humans. ... The answer lies in the evolutionary back-and-forth between newts and garter snakes
Answer:
False. There are 20 amino acids, but 64 possible codons.
Explanation:
Genetic information for the aminoacids assembly during the protein synthesis is stored in short sequences of three nucleotides named codons in the mRNA. Each of the codons represents one of the 20 amino acids used to build the protein. The total number of possible codons is 64, from which 61 codify amino acids -more than one codon codify for the same amino acid-. One of these amino acids is also the start point of protein synthesis. And the left three codons are stopping translation points.
The codons indicating the initiation or stop points during the translation process are:
• The start codon AUG is the most common sequence used by eukaryotic cells and places near the 5´extreme of the molecule. However, other codons might be used as well. Prokaryote cells might use the codons GUG or UUG.
• The end codons are UAA, UAG, UGA.
Answer:
Allele frequency for brown fur color
Allele frequency for orange fur color
Explanation:
Given
"O" denotes dominant brown allele
and "o" denotes recessive orange allelehe
The trait "coat color" is linked with X gene
Brown homozygous females: 30
Brown heterozygous females: 75
Orange females: 10
Brown males: 50
Orange males: 65
Allele frequency for orange color
Thus
Allele frequency for orange fur color
Allele frequency for brown color
Allele frequency for brown fur color

When it rains and everywhere gets wet. See the change
Answer:
The correct answer is - sexual transmission.
Explanation:
HIV infections can be transmitted by the various mode. Sexual transmission is one of the major mode of transmission which is comprise almost 90 % of HIV infection, according to the reports. These are relatively inefficient mode, unprotected or unnatural sex is the major mode for the HIV transmission worldwide. Cases are now comparatively less than when it was discovered due to awareness.
Thus, the correct answer is - sexual transmission.
