A. the number of hydrogen bonds that hold the strands of DNA together
Answer:
The models are missing in the question. The models along with the question is provided in the attachment below.
The answer is : Model A represents the Plasma membrane.
Explanation:
According to the question, model A represents the plasma membrane. The reasons are :
(a). In the model A, the bilayers consists of two leaflets of the amphipathic lipid molecules. Here the polar head groups is in contact with the intra cellular or the extra cellular non aqueous phase, where the non polar tails are facing each other constituting the hydrophobic interior of the membrane.
(b). Lipid are not rigid as well as static structure. In the lipid bilayer, the lipid molecule are able to rotate around their axis freely and diffuse laterally with each leaflet.
(c). The plasma membrane acts as the selective plasma membrane.
Although I forgot the letter that go with this I do remember this topic it would be
ll and then Ll
The atom is made of three subatomic particles.
protons, neutrons, and electrons. The protons and the neutrons make up the center of the atom called the nucleus and the electrons fly around above the nucleus in a small cloud.
Lister’s work was only made possible by Louis Pasteur’s discoveries.
- Louis Pasteur developed the pasteurization technique, which involves heating liquids and then letting them cool in order to kill bacteria, after learning that microbes were the cause of alcohol that had soured.
- His research on germ theory also inspired him and his team to develop the anthrax and rabies vaccines.
- Only Pasteur's discoveries made Lister's research possible. Infection was first thought to be caused by germs according to Pasteur.
- Lister developed the concepts of sterile surgery based on the "germ theory."
- Surgery was transformed into a sterile procedure thanks to Lister and Pasteur.
