1. Some traits are not transmitted via Mendelian inheritance. Describe three forms of inheritance that do not follow Mendelian inheritance or laws. Hint: These are alternative to dominance and recessivness.

1. Use a Punnett’s squares to show a monohybrid cross between pure breeding parents of tall (T) and dwarf (t) pea plants. The tall trait is dominant and thus is represented by the uppercase letter “T”. The dwarf trait is recessive and is represented by to lowercase letter “t”.
2. You have a pea plant with purple flowers but you are unsure of it’s genotype. Since purple flowers is the dominate trait (P), while the recessive trait is white flowers (p), you decide to conduct a test cross to determine the genotype of the purple flowered pea plant. Show how you would do this.

For The introduction include
1) Background about bacteria. specifically the differences between gram + and gram - bacteria. Talk about B. subtilus and E. coli (what they are?)
2) Background on antibiotic resistance, How it formed and how is it affecting the society
3) State the objective of this experiment
4) predictions- please use what I wrote on the board. predictions need to be rationalized, not opinion oriented.
Please write this in order 1, 2, 3, 4. Make sure the organizations are good. also
- Include reference, literature reviews
-No question form
-Paragraph-wise
Methods
-Need to be PASSIVE, don't use I, you, we, the professor
-Make sure you use the correct and precise term
-Please don't divide them into sections, need to be in paragraph
-Need to mention the type of antibiotic used, bacterias used
-Treat this like a real lab experiment
-Don't mention we wait a week. After incubation, it's the measure of ZOI. and that's it.
-Don't be excessive. Only write enough so someone could replicate your experiment.

Fruit flies that breed true for normal wings, grey bodies and red eyes are crossed with flies that breed true for vestigial wings, black bodies and brown eyes.
All the resulting offspring have normal wings and grey bodies and red eyes. The offspring are then crossed with flies with vestigial wings, black bodies, and brown eyes.
The resulting offspring occur:
5 normal winged, black bodies, brown eyes
75 normal winged, black bodies, red eyes
343 vestigial winged, black bodies, red eyes
73 vestigial winged, grey bodies, brown eyes
6 vestigial winged, grey bodies, red eyes
77 normal winged, grey bodies, red eyes
68 vestigial winged, black flies, brown eyes
322 normal winged, grey bodies, brown eyes
A.Are all the genes in cis or trans configuration?
B.What is the order of the three genes?
C.How far apart are the genes for wing type and body color?
D.How far apart are the genes for wing type and eye color?
E.How far apart are the genes for body color and eye color?

1. Meat, eggs, and dairy are good sources of protein. When you eat these foods, proteins are digested and absorbed. Follow a protein through the digestion process from the mouth through to the intestines. What enzymes are involved in its digestion? What is the smallest unit that proteins are broken down into? Where are these products absorbed?
2. What are a few things proteins are used for in the body once they’ve been absorbed?
3. Once in the body, amino acids are absorbed by our cells and enter the amino acid pool. From here, a cell will draw from the pool to assemble the proteins it needs at that specific time. What will happen if one or more of the essential amino acids are missing?
4. Describe (in your own words) the four structural levels of a protein.
5. What is the relationship between a protein’s structure and its function? Explain how amino acids side chains impact protein structure and function.
6. DNA guides protein assembly. When there is a mutation in our DNA, the impact on the protein can vary. Explain why some mutations can cause no change to the protein and some can completely disrupt the function of the protein.
7. Your body prefers not to use proteins for energy, but it will as a last resort. Explain how amino acids are broken down to generate ATP in this scenario.
8. What happens to the nitrogen portion of the amino acid?
9. Your doctor measures your nitrogen balance and finds it is negative. What does this mean about how your body is using protein? How can you balance out your nitrogen levels?
10. If you decided to become a vegetarian or vegan, how would you ensure you were eating adequate protein? Think about not just the amount, but also the essential amino acids.
11. The RDA for protein is listed below. Calculate your own personal protein requirements and show your work for full credit. You will need to convert your weight to kg. There are 2.2 lbs in 1 kg.
Ex: a 50 kg adult would need 50 kg*0.8 g/kg = 40 g protein per day

i NEED TO FIND AN ARTICLE ABOUT USING OF ENERGY IN SUCH AS WORKING, EXERCISE, OR BEING SEDENTRY THEN SUMMERIZE IT
please help me to find an article and summarize it t( the using of energy such as working, being sedentary etc)
Please find an article in the news related specifically to the use of energy (working, exercise, being sedentary, etc.) and summarize it in your own words for the class! Include the name of the article and the source it came from.
i know i post the same before but because it is shown for everybody one of my classmate steal it and post it before i do.. i want the answer hidden please. and dont forget the source of the article please

A 10-4 is performed on a culture of bacteria in order to perform viable plate counts. From the dilution, *0.1 mL* of solution is plated on solid media, and 37 colony forming units grow on the plate.
How many bacteria are in a single mL of the original culture? Express your answer to two decimal places using exponential notation. In exponential notation 540 would be written as 5.E2. Please use an upper-case letter E.
