Natural selection affects allele frequency. If an allele confers a phenotype that enables an individual to better survive or have more offspring, the frequency of that allele will increase.

Several organisms have a homologous protein (inherited from a common ancestor) that is highly similar at the amino acid level. Y
8_murik_8 [283]

Answer:

The correct answer is: C. third nucleotide position.

Explanation:

  • Genes located on the chromosomes encodes for proteins.
  • A Gene is made up of a  Deoxyribonucleotide (DNA) sequence which is transcribed into the messenger Ribonucleotide (mRNA) sequence by the help of RNA polymerase.
  • This mRNA sequence is further translated into the amino acid sequence, that folds to form the functional protein, by the help of the Ribosome.
  • The Ribosome reads the mRNA sequence in the form of triplets (three nucleotide together) and each such triplet nucleotide codes for an amino acid.
  • Each such triplet nucleotide is known as a Codon.
  • The Genetic Code is a table which represents the  amino acid encoded by each codon.
  • However, the Genetic Code is degenerate in nature. This means that one amino acid can be coded by more than one codon.
  • This is because, among the the three nucleotide positions in a codon only the first two determine the specificity of the amino acid while the third nucleotide, also called the wobble nucleotide, is not specific. Presence of any nucleotide in the third position of the codon will not alter the amino acid encoded by the codon.
  • In the given question, organisms producing homologous protein have similar amino acid sequence but they vary in the corresponding nucleotide sequence of the gene which codes for the homologous protein.
  • This is because at the nucleotide level the variation lies in the wobble nucleotide position that occupies the third position in the codon.

Fed [463]
The horrific forced transport of Africans into America during the age of exploration as part of the slave trade that was going on where Africans were transported on ships from Africa, chained up like animals all the way to America was an example of international migration affecting the population. 

External influences forced Africans to go from Africa to another continent and live there.

In hot weather, the testes are protected from the heat by relaxation of the dartos muscle. relaxation of the dartos muscle, cont
liubo4ka [24]

Answer:

Relaxation of the dartos muscle.

Explanation:

Testes are present in scrotum outside the pelvic cavity to maintain the temperature about 2-3 degrees Celsius below the body temperature as required for sperm production. Dartos muscle is the layer of smooth muscle located in the superficial fascia. The contraction of dartos muscle serves to make the skin of the scrotum wrinkled and tight.

During hot weather, the dartos muscle relaxes and makes the surface of scrotum less wrinkled to increase the loss of the heat from its surface. The increased heat loss from the surface of scrotum due to relaxed dartos muscles keeps the testes protected from heat.
