compare and contrast pseudopod, flagella and cillia ?

You are studying a microbial species that divides by binary fission. Which of these do you expect to happen in the culture as is grows in a laboratory setting? Check all that apply.

-you expect the size of each cell to greatly increase over time, rather than the number of cells increasing much

-you expect the total biomass (weight) of cells to increase over time

-you expect the biomass to stay the same

-you expect the number of cells in the culture to increase, rather than each cell increasing much in size

1) What is endosymbiosis? Which organelles may have arisen this way? What evidence is there for this theory?

2) Which cells in our bodies have cilia and flagella? Can you find other examples? How do these structures differ in structure and movement? How are they similar?

3) How do flagella differ between prokaryotes and eukaryotes?

In garden peas, inflated pod shape (I) is dominant to pinched pod shape (i) and yellow pea colour (Y) is dominant to green (y) pea colour. Plants heterozygous for these characteristics were selfed (note that this is not a test cross), and the following numbers of phenotypes were seen in the progeny: 556 inflated, yellow; 193 inflated green; 184 pinched, yellow; 61 pinched green Test the data for the involvement of two independently assorting genes using the Chi-square test (don’t forget to state your Null Hypothesis).

Write a 700-800 word APA format essay explaining the human blood type inheritance.

What are the important aspects of the vitamin including the most common functions/roles in the body? What are 5 top food sources of vitamins?

1. Explains the symptoms/conditions a person might develop if he/she is deficient or excess in this vitamin or mineral. If there are conditions that may lead to or cause deficiencies, those should be discussed.
2. Describe what may inhibit and/or improve the bioavailability of this nutrient. This information is found for most vitamins and minerals in the text.   If there is nothing in your specific section, look at the beginning of the fat soluble and major mineral chapters for more general information. Those two chapters have overall information on bioavailability for all vitamins and minerals.

Mr Nel is a chronic cigarette smoker for the last 20 years. He smokes between 30-40 cigarettes every day. He is overweight and has a sedentary lifestyle working for a computer company. At home he is always tired and not in the mood to exercise. Sometimes he has difficulty to breathe.

Predict the effect of mr Nel’s lifestyle on his spirogram, therefore his lung volumes and write a CONCLUSION. Refer to his tidal volume, inspiratory reserve volume, forced expiratory volume in 1 second and his total lung capacity.

how can electrophoretic techniques be used to analyse defects in mitochondrial respiratory chain complexes?

If plants with wrinkled seeds are 100% selected against, how many generations would it take to remove a recessive allele? Explain (round seeded plants are either RR or Rr)

1. Which of the following statements about Na+ -K+ pump is incorrect?

Select one:

A. The Na+ -K+ pump is an antiport that moves the ions against their concertation gradient.

B. The Na+ -K+ pump is an example of secondary active transport.  

C. The Na+ -K+ pumps potassium against its concentration gradient.

D. The Na+ -K+ pump moves Na+ out of the cell and K+ inside the cell.

E. The Na+ -K+ pumps sodium against its concentration gradient.

2. In general, transport of glucose in and out of cells always occurs down its concentration gradient.

Select one:

A. True  

B. False  

3. Glucose transport in in the interstitial epithelium (from the lumen or cavity to enterocyte) via the SGLTI.

Select one:

A. Is an example of simple diffusion because glucose moves from high concentration in the lumens to low concentration in the enterocyte.

B. Is an example of secondary active transport because glucose uses the sodium of gradient.

C. Is an example of facilitated passive transport because glucose moves from high concentration in the lumen to low concentration in the enterocyte.

D. Is an example of primary active transport that uses a glucose and ATP hydrolysis.

4. Neurotransmitter are synthesized in the cytoplasm of the cell vesicles for storage. Neurotransmitter use a antipode exchanger protein that is proton dependent.

Based on the information above, it can be concluded that   

————.

Hint: this transport is an example of secondary active transport.

A. The PH in the interior of the vesicle is higher than the cytoplasm.

B. The PH in the interior of the vesicle is lower than the cytoplasm.

1. Can iodine be added before the primary stain in a Gram stain? Explain. If iodine was added before the primary stain, what would be the final color of gram positive and gram negative cells in the stain and why?

2. Since you can’t identify bacteria from a Gram stain, why might a physician perform a Gram stain on a sample before prescribing an antibiotic?

3. The cell envelope of Mycobacterium sp. is unlike the envelope of other bacteria. While genetic evidence indicates that these organisms are related to gram-positive bacteria, one could argue that their structural characteristics could place them in place them among the gram-positives or the gram-negatives. Explain.

Q1. Choose all enzymes that participate in the translation processes. ( Select all that apply.)

A. release factors

B.DNA polymerase II

C.aminoacyl tRNA synthetases

D.large subunit ribozyme

E. DNA polymerase I

D. DNA polymerase III

Q2.  Which of the following is not a disorder caused by the aggregation of misfolded protein?

A. Parkinson's Disease

B. sickle-cell anemia

C. Huntinton's Disease

D. Alzheimer's Disease

E. alkaptonuria

A major theme in biology is the relationship between form and function in organisms. Select one of the major characteristics from these organisms (sponge, Hydra, Roundworms, Clam, Earthworms, Planarian) and illustrate the relationship of form and function for this characteristic.

Match the following descriptions to the most appropriate method of genome engineering presented within the list. Use each answer once. List: MuGENT, Transformation, CRISPR, Transposon mutagenesis, and MAGE.

a. You are attempting to see the effect of substituting similar amino acids across the genome (called conservative replacement). Thus, by using _____ you try and replace all glycine codons with alanines.

b. You are looking to create a heterogenous mixture of knockout mutants from a pool of 6 genes.

c. A broadly-applicable technique that can make efficient gene edits based on guide RNA.

d. You are looking to randomly disrupt genes within the genome to assess their function.

e. Using a PCR fragment with homology to the genome, you must get this DNA into your target cells somehow...
