Question
Chapter 12, Problem 10WIO
Summary Introduction
To explain:
The oscillation in the allele frequencies of A gene.
Concept Introduction:
A small population of the earthworm is pouredin a glass that contains a gene (A) has no fitness effect in the population. Scientist studied the frequency of (A) gene for 20 worm generations. (A) gene contains two alleles that are (A) and (a). During the first generation, (A) allele is present in the population, by the fifth generation, an allele becamemore common than (A). By the twentieth generation, (A)allele became morecommon. The oscillation of allele frequencies of gene (A) occurred due to directional selection.

✓ Details
Draw a protein that is embedded in a membrane (a transmembrane protein), label the lipid bilayer and the protein. Identify the areas of
the lipid bilayer that are hydrophobic and hydrophilic.
Draw a membrane with two transporters: a proton pump transporter that uses ATP to generate a proton gradient, and a second
transporter that moves glucose by secondary active transport (cartoon-like is ok). It will be important to show protons moving in the
correct direction, and that the transporter that is powered by secondary active transport is logically related to the proton pump.
drawing chemical structure of ATP. please draw in and label whats asked. Thank you.

Affected individuals show spots of abnormal skin pigmentation and non-cancerous tumors that can interfere with the nervous system and cause blindness. Some tumors can convert to a cancerous form. i The recessive form is a normal protein - in other words, no neurofibromatosis.moovi A typical pedigree for a family that carries neurofibromatosis is shown below. Note that carriers are not indicated with half-colored shapes in this chart. Use the letter "N" to indicate the dominant neurofibromatosis allele, and the letter "n" for the normal allele.
