The easiest example here is a computer/laptop... e.g. when the CD-ROM is spinning when you are perhaps playing a movie, the kinetic energy causes friction, which results in heat. All computers need a fan to prevent them over-heating for this very reason. Therefore heat is lost and energy is wasted.
Another example is a lightbulb. When a light is switched on and left for a long time, the current flowing through the filament (the thin bit of wire in the bulb) causes heating (due to electron-ion collisions but you may not need to know that) so energy is wasted as thermal energy instead of light energy.
These are just a few examples but other ones you could use are tv screens, kettles, toasters, etc :)
Answer: Phagocyte receptors that detect PAMPs
Explanation:
TLRs or Toll-like receptors, are a family of proteins that are part of the innate immune system. TLRs are transmembranous and recognize pathogen-associated molecular patterns (PAMPs), which are groups of chemical characteristics common to certain types of pathogens. Patterns detected by TLRs include lipopolysaccharide, a compound found on the surfaces of Gram-negative bacteria, and double-stranded RNA, which is an integral part of the life cycles of many viruses. These PAMPs are generally important for the survival of the pathogen, so they are well preserved. <u>Activation of these receptors induces inflammatory responses in leukocytes of myeloid lineage, signaling via NF-κB, which is a transcription factor that activates pro-inflammatory genes</u>. Activated TLRs also increase the production of co-stimulatory molecules such as CD80, CD86 and CD40. These proteins, expressed on the surface of antigen-presenting cells, are necessary for the activation of T-lymphocytes by dentritic cells and macrophages already showing antigens in their MHC type II molecules (Major Histocompatibility Complex, they participate in the presentation of antigens to T lymphocytes)
<u>In addition, TLR-mediated signaling on antigen-presenting cells (APCs) plays an important role in linking the innate and adaptive immune responses</u>.
Answer:
There are two cells produced in the process of mitosis.
New cells are formed by the process of cell division.
Yes, Cells made during mitosis are identical.
Mitosis is the process in which two daughter cells are produced during cell division.
Phases of mitosis are prophase, metaphase, anaphase, and telophase.
Prophase is the longest phase in which chromatin condenses chromosome.
In metaphase chromosome are separated from each other.
Anaphase is a phase in which daughter chromosome move toward the pole.
In telophase, the cell is divided into two daughter cells.
Two daughter cells are produced during mitosis.
Cytokinesis is a process in which cytoplasm of the cells is divided into two.
