Answer:
target cell
Explanation:
Cell communication includes one or more signaling cells and the target cell. Signaling cells produce signals. In the case of chemical signaling, the signaling cells produce chemical signals such as hormones or neurotransmitters or ligands. Target cells are the cells that respond to a specific signal produced by the signaling cell.
To receive and respond towards the signal, the target cells produce receptors where the signaling molecules bind to produce the desired effects in the target cells. For instance, liver and muscle cells are one of the primary target cells for the pancreatic hormone insulin.
They can kill animals also can Barry and crush people and their homes hope this helps.
<h2>Down Syndrome</h2>
Explanation:
Down syndrome is a genetic disorder caused when abnormal cell division results in an extra full or partial copy of chromosome 21
- Down syndrome is a genetic disorder caused when abnormal cell division results in an extra full or partial copy of chromosome 21
- Down syndrome is usually caused by an error in cell division called nondisjunction which results in an embryo with three copies of chromosome 21 instead of the usual two
- Prior to or at conception, a pair of 21st chromosomes in either the sperm or the egg fails to separates
- With development in embryo the extra chromosome is replicated in every cell of the body;this type of Down syndrome which accounts for 95% of cases is called trisomy 21
- Maternal age is the only factor that has been linked to an increased chance of having a baby with Down syndrome resulting from nondisjunction;here environmental agents such as drugs, chemicals, and radiation act as mutagens which induce mutation in the fetus
