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:
Chloroplast
Explanation:
Fungi organisims are complete eukaurions, either it is plury or unicelular, it will allways have a definited nucleus, Golgi apparatus, reticulum, vesicles, and other. Generally, they have mitochondrions as machinary to get ATP; but some lesser, and specific fungis like thoses in the order Microsporidian, lost them through evolution.
Either way, a fungi does not have chloroplast, being an chemeotroffic organism, it have to adquire carbon and nitrogen sources from others.
Answer:
Explanation:
Eukaryotic cells are cells that contains a membrane bound organelles this include the nucleus while prokaryotic cells do not have a membrane bound nucleus.
Eukaryotic cells have more than one One chromosome while prokaryotic cell has one chromosome that is not true chromosome.
Eukaryotic cell have a multicellular cell type while prokaryotic cell have a unicellular except for some cyanobacteria that may be multicellular.
Cell wall is present in eukaryote only in plant cells and fungi and it chemically simpler while prokaryote cell wall is Usually chemically complex
Lymphocytes that destroy foreign cells or virus- infected cells are cytotoxic T cells.
<h3>What is cytotoxic T cell?</h3>
- A particular class of immune cell that is capable of eliminating specific types of cells, such as virus-infected cells, cancer cells, and alien cells.
- To destroy cancer cells, cytotoxic T lymphocytes can be isolated from other blood cells, cultured in a lab, and then administered to a patient.
- White blood cells and lymphocytes both fall under the category of cytotoxic T lymphocytes.
- It is also known as a killer T cell and a cytotoxic T cell.
- The helper T cell and the cytotoxic T cell are the two main subtypes of T cells.
- Helper T cells, as their names imply, "assist" other immune system cells, whereas cytotoxic T cells "kill" virally-infected cells and tumours.
- The TCR cannot directly bind antigen, unlike an antibody.
