As a toxicologist, you are given the assignment of determining whether a new chemical is capable of producing dermal sensitization. Explain how you would test for this. Include in your explanation the model/test system you would use and a brief description of how the test is run and interpreted.

Hint: You will need to use resources outside the textbook to answer this. There are many standardized protocols that will be easy to find. Please include in your answer why you picked the test(s) you selected.

What is this Corona disease? Where is disease prevalent? What organisms does this disease infect and how is it transmitted from host to host? Details.

I have this question, and I have to answer it as essay (for my project). Can you help me. Please can you type the answer. I don't understand the writing hand. Sometime.

Thanks

BIOCHEMISTRY ASSIGNMENT

UNIT TITLE: BHND 222/CHTU 125/BEH 125

1. 1. Name all the enzymes and co-enzymes involved in digestion of carbohydrates, Lipids and proteins in the human body from the mouth to intestines and up to absorption to the liver
2. Describe the metabolic pathways for glucose, amino acids and fatty acids and glycerol in the Liver
3. a) Draw the Animal cell and its detailed organelles and describe the structure of the cell membrane b) Explain the transport mechanisms across the cell membrane.
4. Explain the processes of lipogenesis and Gluconeogenesis
5. Write about glycogen storage disease
6. List various types of eicosanoids and explain their importance in the body.
7. Discuss four diseases associated with nucleic acids’ impairments.
8. Discuss the formation and transit of high density lipoproteins and low density lipo proteins
9. Discuss Nucleic Acid drawings, components and structures.
10. Describe the following cycles in the human body
11. a) Pyruvate cycle b) Cori-cycle     c) urea cycle    d) Krebs cycle      e) amino acid synthesis

The ligands bound to the mammalian GDH can tell us if and how this enzyme is regulated. How is the bovine GDH regulated and which ligands are involved in each type of regulation?

There are rare cases where a base substitution mutagen can revert a frameshift mutation if the frameshift mutation is early in a DNA coding sequence. Suggest a mechanism by which this could occur.

1. Ability to taste phenylthiocarbamide (PTC) is mostly determined by the gene PTC. The letters T and t are used here to simplify analysis. TT individuals taste a strong bitter taste; Tt people experience a slightly bitter taste: tt individuals taste nothing. A fifth-grade class of 20 students tastes PTC that has been applied to small pieces of paper, rating the experience as “very yucky” (TT), “I can taste it” (Tt), and “I can’t taste it” (tt). For HW, the students test their parents, with these results:
   1. 1. Of six TT students, four have two TT parent and the remaining two have one each of TT and Tt parents.
      2. Of four Tt students, who have two parents who are Tt, and two have one parent who is TT and one parent who is tt.
      3. Of the 10 students who can’t taste PTC, four have two parents who are also tt, but four students have one parent who is Tt and one who is tt.   The remaining two student have two Tt parents.
   2. Calculate the frequencies of T and t alleles in the two populations (parents and children). Is the Hary-Weinberg Equilibrium maintained.

Why does nitrogen assimilation in plants cost energy?

Dimples is dominant over smooth cheeks, and brown eyes are dominant to blue. A blue-eyed woman with dimples (both her parents had brown eyes, her mother had dimples and her father had no dimples) marries a brown-eyed man with dimples (his father had blue eyes and dimples, his mother had brown eyes and no dimples). What is the probability that their first child will have blue eyes and dimples?

1) . Name the three types of muscle and complete the below chart

Type Voluntary or involuntary?

Striated or not‐striated?

Shape/description Special features (nucleus, disks, shape,

2) In what ways are areolar and fibrous tissue similar? In what ways are they different?

3) Give 2 ways that cartilage and bone are similar:

4) Give 2 ways that cartilage and bone are different:

5) Does each type of connective tissue have only 1 type of fiber? Explain

6) What are the different fiber types found in connective tissue? Describe how they differ

In an African population the ABO blood group antigens alleles at the I locus were found in the following frequencies: IA = 0.12 IB = 0.56 IO = 0.32 What are the expected genotype frequencies in the population? what are the expected frequencies of the A, B, AB, and O blood types? (remember IA points) and IB are codominant alleles and IO is a null allele).

True or False. A. Eukaryotes cannot be viewed with a compound light microscope.

B. Eukaryotes have membrane-bound organelles that can be seen under low or high-dry powered objectives.

C. Prokaryotes can be seen easily using a wet mount and don't require staining because of their large size.

D. Prokaryotes are larger than eukaryotes but require staining view.

E. Prokaryotes have membrane-bound organelles but their thick cell wall prohibits this observation.
