Question

Question 2 1.25 points Saved Which of the following would increase the fluidity of a cell's plasma membrane at room temperature? A. adding unsaturated phospholipids B. Adding water to the membrane C.Adding saturated phospholipids D. removing cholesterol Question 3 1.25 points If sodium chloride is dissolved in water, how will the nearest water molecules be oriented around the sodium atoms? A. The water molecules will be largely just hydrogen bond to each other like bulk water B. The water molecules will prefer to point their oxygen atoms towards the sodium C. The water molecules will prefer to point their hydrogen atoms towards the sodium The water molecules will form an ice-like structure since sodium is non-polar Question 15 1.25 points Save Which of the following is NOT characteristic of the lysogenic cycle of bacteriophages? A. Viral DNA is incorporated into the host genome B. The viral genome will be passed to another bacterial cell through a sex pillus C. The viral genome is only passed down to one daughter cell after binary fission D. The virus-host relationship usually lasts for multiple bacterial generations Amount of DNA in Time The figure above shows how the amount of DNA in a recipient cell (F- cell) changes after it comes in contact with a Hfr cell. Which of the following statements is the best description of this cell at time point 4? A. The F- cell is now a Hfr cell B. The F- cell now has a different DNA sequence than it did at time point 1 C. The F- cell has now become a F+ cell D. The F- cell now has two chromosomes in it

Explanation / Answer

2- Unsaturated fatty acid and cholesterol increase the fluidity of the membrane.

So answer is option A

3- In the water molecule, Oxygen atom has a slightly negative charge due to its electronegativity. In NaCl, sodium has the positive charge. As we know that negative charge attracts towards the positive charge So option B is correct.

15- VIral genome which is integrated into the host genome also divided along with the host genome. So it is passed down to its both progeny.

So option C is the wrong option

C is correct.

13 bacteria which have lipopolysaccharide layer shows the halo around them

SO option A - fimbriae is not correct

Virus question -

Vuris uses host RNA polymerase and host NTPs to carry out the process of transcription

So option C- is the correct option
