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.
Answer:
B
Explanation:
Proteins do store energy and nucleic acids provide energy thats why B is correct.
Explanation: Natural gas is a limited resource. Natural gas is in the fossil fuel family and it's underground. I think it's pretty plentiful meaning that there's a lot in the United States of America. Many people use it for home heating instead of heating oil. Some people have oil trucks where the oil truck has to come and deliver oil to them.
So, natural gas is limited resource because it's a fossil fuel and it gives off emissions. It's in the ground and it's from years of decaying stuff. It's not like solar or wind power, it's a limited resource.
Answer:
To electromagnetic radiation can be harmful depending on the frequency of radiation, which can range from microwaves that raise tissue temperatures, infrared radiation that produces heat and burns, x-rays can cause problems such as mutations associated with cancer and cell death , similar to ultraviolet radiation that can range from darkening the skin to promoting the appearance of cancer.
Among the beneficial effects, voltages similar to those produced by the connective system have been developed, to improve the treatment of different musculoskeletal diseases, also some radiation show benefits to treat some types of cancer, they are also used for sterilization of medical instruments or places requiring to be free of bacteria, x-rays are used as diagnostic means for studying bone and related injuries, radiation in the form of laser allows surgical procedures.
Sickle Cell is a disease but also a gene thing, about 25% possible but other then not, it would not be possible.
