Answer:

Laser-assisted in situ keratomileusis

Explanation:

Laser in-situ Keratomileusis (also known by the acronym LASIK) is a surgical procedure based on the use of a cutting instrument called a microkeratome. The surgeon makes a cut in more anterior regions of the cornea and then uses a laser at these locations to reshape the cornea. After this, the surgeon places the cut cornea again at the cut site, allowing this tissue to reintegrate into the cornea within a few days.

taurus [48]

Answer:

of the low pH of the vagina.

Explanation:

The pH of the vagina is maintained at highly acidic levels to prevent the germ buildup. The range of vaginal pH is around 3.8 to 4.5. The very low pH of the vagina creates a hostile environment for sperms and most of the sperms are killed as they enter the vagina due to the acidic pH.

Apart from supplementing the sperms with energy, cervical mucus serves to protect the sperms from the hostile conditions of the vagina. The cervical mucus has an alkaline pH at or near the ovulation to protect sperms from acidic pH of the vagina and to facilitate fertilization.

A bacterium is infected with an experimentally constructed bacteriophage
dem82 [27]

The complete question is:

a bacterium is infected with an experimentally constructed bacteriophage composed of the T2 phage protein coat and T4 phage DNA. The new phages produced would have

A) T2 protein and T4 DNA

B) T2 protein and T2 DNA

C) a mixture of DNA and proteins of both phages.

D) T4 protein and T4 DNA

E) T4 protein and T2 DNA

A bacterium infected with an experimentally constructed bacteriophage will give new phages with the virus' DNA and the type of proteins that this DNA encodes.

A bacteriophage is a virus that attaches itself to a bacteria and uses it to replicate itself. Viruses have two main parts, a protein coat and their DNA inside it.

  • The experimentally constructed bacteriophage has one type of protein that makes the coat, the T2. This type of protein will allow the virus to attach and infect the bacteria.
  • Once the virus attaches itself to the bacteria, it will introduce its DNA, T4 type, and use the bacteria elements to replicate it and create new phages.
  • As a result, the new phages will have T4 DNA, and the proteins that the virus synthesizes will be the same type as the DNA.

In conclusion, The new phages produced would have D) T4 protein and T4 DNA.
