Cytoplasmic matrix I believe:)
Explanation:
adrenocorticotropic hormone= It stimulates the adrenal cortex.
What's true of any eukaryotic cell, because whether or not they are in a multicellular organism they still contain this one characteristic, is that they contain a nucleus. A nucleus is a membrane-bound organelle inside a eukaryotic cell, and this cannot be found in any prokaryotic cells such as bacteria or archaeans. The other three characteristics can all be found in bacteria and archaea.
Answer:
Interphase is the longer phase where cell prepares itself for mitosis.
Interphase is the time when a cells metabolic activity is very high as it performs various functions.It is divided into G1,S PAHSE and G2.
G1 phase
synthesis of proteins
synthesis of organelles
growth in size
Sphase
duplication of chromosomes
growth in size
G2 phase
more growth
synthesis of proteins essential for mitosis
Explanation:
Answer:
The human cell system has a pretty advanced and effective way of communication. This communication between cells, whether it be of a single system, or between systems, is carried out by chemical reactions and gradients, and also through the intercession of molecules known as neurotransmitters. This is the case of the nervous system and its means of communication.
When we talk about neurotransmitters (the messengers) and neuroreceptors (the gatekeepers that receive the message and produce a reaction), we are literally talking about communication in the nervous system.
There are two types of neuroreceptors for trasmitters: the ionotropic (ligand-gated ion channels) and the metabotropic (second-messenger gated receptors, or G-protein coupled receptors). While the first type depends entirely on the availability of a ligand that binds to the receptor to open up the influx of ions from outside and inside of the cell to create a gradient that will ensure a cell response, the second does not open any ion channels and literaly what it does is receive the message from a neurotransmitter, and through the G-protein bound to the receptor, once it gets the necessary message, detaches and carries out the information to the cell. This is broadly how neurotransmittion can be carried out in the nervous system.
