What else can I help you with?
When a change in the environment that initiates the transmission of an electrochemical charge along a neuron is known as?
A momentary change in electrical potential on the surface of a cell, especially of a nerve or muscle cell, that occurs when it is stimulated, resulting in the transmission of an electrical impulse. &/or "nerve impulses" or "spikes".
What occurs in a cell causing a change in the DNA?
A mutation.
What is depolarization of the sarcolemma?
Depolarization of the sarcolemma is the process where there is a change in the electrical charge across the cell membrane of a muscle cell. This change in charge helps to propagate an action potential along the cell membrane, initiating muscle contraction.
How often does DNA replication occur in a cell's life cycle?
DNA replication occurs during the S phase of the cell cycle, which happens before cell division. This process typically occurs once in each cell cycle.
A sudden change in the DNA of a chromosome can usually be passed on to future generations if the change occurs in a?
That would be the sex cell.
When a cell membrane is completely depolarized the charge on the inside of the cell membrane is what?
When a cell membrane is completely depolarized, the charge on the inside of the cell membrane becomes positive relative to the outside. This occurs due to the influx of sodium ions (Na+) through voltage-gated channels, which reverses the typical resting membrane potential. In this state, the inside of the cell can reach a positive voltage, often around +30 mV, before repolarization occurs.
potential increases positively. This typically occurs due to?
an influx of sodium ions into a cell
Can you change your voicemail without cell service?
No, you typically need cell service or a Wi-Fi connection to change your voicemail greeting on a cell phone.
What type of cell division occurs in cloning?
Cloning typically involves somatic cell nuclear transfer, where the nucleus of a somatic cell is transferred into an enucleated egg cell. This process leads to the creation of a genetically identical organism to the original donor.
Is depolarisation same as relaxation?
No, depolarization refers to the change in electrical charge within a cell, typically leading to stimulation or activation. Relaxation, on the other hand, refers to the release of tension or reduction in activity within a muscle or cell. They are separate physiological processes.
Where in the cell transcription occurs?
It occurs in the nucleus of the cell.
What is the sequence through which a charge flows in an electrochemical cell?
In an electrochemical cell, the charge flows from the anode (where oxidation occurs) to the cathode (where reduction occurs) through an external circuit. At the anode, electrons are lost during oxidation reactions, while at the cathode, electrons are gained during reduction reactions. The flow of charge through the external circuit is driven by the potential difference created by the redox reactions happening at the electrodes.
