In an experiment, you create two groups of liposomes in a solution containing 0.1 M NaCl—one made from red blood cell membranes

and the other from frog egg cell membranes. When the liposomes are placed in water, those with red blood
cell membranes burst more rapidly than those made from egg membranes. Evaluate each of the following statements and identify those that could explain these results.

• T/F The red blood cell liposomes are more hypertonic relative to water than the frog egg liposomes.
• T/F The red blood cell liposomes are more hypotonic relative to water than the frog egg liposomes.
• T/F The red blood cell liposomes contain more aquaporins than the frog egg liposomes.
• T/F The frog egg liposomes contain ion channels, which are not present in the red blood cell liposomes.

Answer:

As liposomes with red blood cell membranes burst more rapidly than those made from egg membranes, we consider these liposomes as more hypertonic respect to water, than those derived from frog egg cells.

Explanation:

Osmosis is a process where water can cross a semipermeable membrane in a gradient way.  Water tends to move from a high concentration of solvent to a low concentration.  Then, water goes in through the liposome to dilute its solute content, as it's not easy for molecules inside to go out of the usually impermeable membrane bilayers.

vaieri [72.5K]

The correct answer is genes.  

A trait refers to the feature like size or color, which is passed from the parents and is inherited by the offspring. The genes control traits and come in pairs, that is, one gene from each parent.  

The transmission of hereditary traits possesses its molecular framework in the accurate DNA replication. This generates gene copies, which can be transmitted to the offspring from the parents. In plants and animals, the reproductive cells known as gametes are the mediators, which transfer genes from one generation to the next.

In humans, dimples (D) are dominant over no dimples (d). Curly hair (A) is dominant over
jeyben [28]

Answer:

1. ddaa

2. DdAa

3. One from each parent

4. False

5. 0.25

6. 0.25

7. 0.25

8. 0.5

Explanation:

The remaining part of the question is  

1. What is Jane's genotype?  

2. What is Paul’s genotype?  

3. Where did Jane get her gene for curly hair? From her mother or father?  

4. True or False: Jane's mother was heterozygous for curly hair?

5. What fraction of Paul and Jane's children should have curly hair and dimples?  

6. What fraction of their children would have straight hair and no dimples?  

7. What fraction should have dimples but not curly hair?  

8. What is the probability of getting any offspring with dimples

Solution

1. Genotype of Jane's mother -ddaa

2. Genotype of Paul (heterozygous for dimples and curly hair) – DdAa

3. One “a” gene from mother (whose genotype for hair was aa) and second “a”gene from father (whose genotype was  Aa)

4. False.  She was having straight hair

5. Offspring of  Paul and Jane  

DdAa (4), Ddaa (4), ddAa(4) and ddaa (4)

4 out of 16 offspring will have curly hair and dimples = 0.25

6. ddaa, 4/16 = 0.25

7. Ddaa , 4/16 = 0.25

8. Ddaa, DdAa, 8/16 = 0.5
