Nutrition science:

(maximizing carbohydrate) In a short paragraph, what way's can one maximize the quality of carbohydrates by having whole-grains, high fiber, low fat, and a low glycemic index. Does it seem like one could meet all these criteria with a few, well-chosen foods? Or does it seem like a task for a professional nutrition counselor?

Vitamin recommendations and claims can be confusing and misleading. A little knowledge is power – your power to choose. How will a person be sure to get all the vitamins they need? What do you see as some of the most important links between foods, vitamins, and preventable medical conditions at home and around the world? In a short paragraph, explain your best hypothesis about the connections.

Consider a farm planted with corn being infested with caterpillars. During the first pesticide application out of twenty (20) caterpillars sprayed, only five (5) were killed. After some times, the fifteen (15) individuals that survived grew in number to about thirty (30) individuals. Another application was done and about twenty-five (25) individuals were killed.

i. What is the pest and the type of pesticide used by farmer?

ii. Does the pest of corn exhibit pesticide resistance?Justify your answer.

iii. List the stages of pesticide resistance described in the paragraph. (NOTE: Write only the stage reflected in the paragraph.)

. Let’s imagine that we are studying only one trait, that of green- or yellow-colored seeds. Mendel bred his peas until they either produced seeds of one color or the other. These purebred plants he called the p generation (“p” for parental generation). He then cross bred green plants with yellow ones and discovered that all the offspring were yellow-colored. Mendel called the offspring of the purebred plants the F1 generation.

In your own words, explain why all the offspring in the F1 generation were yellow instead of half being yellow and half green, or some other mix of the colors. Hint: Remember that Mendel coined the terms dominant and recessive. must be 75 words

Another disease caused by a mutation in a single gene is Huntington’s disease (HD), an autosomal dominant condition. It is caused by mutations in a gene required for normal nerve cell function. The mutations cause abnormal proteins to be produced which “stick” together and accumulate in nerve cells, eventually interfering with normal cell operations. Suggest two ways you could treat the disease by targeting the translation step for the HD protein and justify why each approach might be effective.

Briefly describe the process by which the body strips electrons from food molecules (use a polysaccharide made up of glucose monomers as an example) and uses them to power the electron transport chain.

GENETICS:

Please provide a good explanation why the answer is transcription. (visual learner.)

You are studying chemicals (A,B,C,D, and E) and treat cells with each compound. You measure RNA and protein. RNA is detected in all of your cultures except the one treated with compound A. What process in the cell is compound-A inhibiting?

a. transcription

b. replication

c. translation

d. splicing

e. cloning

Julia works for company X, a high-profile tech firm that provides in-house daycare, hourly snacks delivered to the workers desks, an on-site workout facility with a pool and a company doctor. Julia is allergic to apples. She tells everyone that will listen; all her co-workers are annoyed with her, they roll their eyes every time that she explains that no, she cannot have the apple slices that are provided for them every hour as their healthy alternative snack and she insists on having a special snack of M&Ms provided for her. She asserts that when she eats apples, she gets a stomach-ache and flatulence (as all her co-workers can attest to). One day in December, company X hired Sam. Sam also has an apple allergy, when he eats apples, his mouth, lips and tongue swells. His doctor has prescribed eppi-pens for his allergy. Sam is an antagonistic person and likes to make fun of Julia for her “pretend allergy.” Julia is not amused. Julia followed Sam one day and saw him eating an apple pie with is family! Julia’s suspicions were confirmed – Sam was just looking for attention. An all-out apple-war starts out at company X. Finally, John, a mutual coworker brings the company doctor in to settle this feud; she is able to listen to both parties and give diagnoses without running any tests. Peace is eventually restored and Julia and Sam get back to work.

Draw the structure of the molecule that Julia is “allergic ” to, what classification of biomolecule does this fall under?

What is actually going on with Julia? Is she actually having an allergic reaction to the molecule above? If yes, explain. If no, what is actually happening in Julia’s body and give the name of her disorder.

What type of molecule is Sam allergic to?

Why can Sam eat apple pie, but not raw apples?
