<h2>Answer:</h2>
Gastrin and Glucagon
<h2>Explanation:</h2>
Two primary hormones that are secreted by the pancreas are:
Gastrin: This hormone helps in digestion by stimulating certain cells in the stomach to produce acid.
Glucagon: Glucagon helps insulin to maintain normal blood glucose by working in the opposite way of insulin.
After we finish taking shower the pancreas releases these two primary hormones.
Answer:
Zooplankton
Explanation:
The correct answer here would be the zooplankton. (see the attached image)
<em>Due to the important position of the Zooplankton in the food web, any change in the environment that removes them will cause the most instability in the ecosystem. </em>
<em>Five different organisms within the food web directly depend on the zooplankton for their food four of which have no any other option. Removal of zooplanktons from the environment will directly affect these organisms and this will throw the entire food web into disarray.</em>
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.
