Question

the making of the fittest: natural selection and adaptation questions 1 where is the melanocortin 1 receptor located, and what is its role in the cell? 2. a. what does the following shape on the gene tables represent? b. why is the phospholipid membrane included in the figure with respect to the receptor’s location and three - dimensional structure? (hint: refer to the introduction and question 1 above.) 3. using the information provided in the introduction, create a simple flowchart depicting the mc1r pathway. there should be a minimum of five steps in the pathway. be sure to include reception, a portion of the transduction pathway, and the cellular response. 4. complete the table below comparing the chemistry of amino acids in the wild - type mc1r protein and the mutant mc1r protein. comparison table | amino acid mutation position number | wild - type mc1r amino acid chemistry | mutant mc1r amino acid chemistry | | ---- | ---- | ---- | | example 1 | polar (hydrophilic), neutrally charged | electrically charged, negative (acidic) | 5. the wild - type (normal) mc1r gene results in the light coat - color phenotype, while the mutated mc1r gene results in the dark coat - color phenotype. based on your knowledge of the mc1r signaling pathway (question 3), cell signaling, and the chemistry of the amino acid changes (question 4), write a hypothesis for each of the following questions.

Explanation:

The problem is about the MC1R pathway, receptor location, gene table shapes, amino acid chemistry comparison, and hypothesis writing related to coat - color phenotypes. These topics are related to the study of living organisms at the cellular and molecular level, which falls under the subfield of Biology in Natural Science.

Answer:

The subfield is Biology (under Natural Science).
