What initiates an action potential on a muscle cell?

Answers

a change in membrane potential

Final answer:

An action potential in a muscle cell is initiated by acetylcholine, which binds to receptors on the muscle cell membrane, causing depolarization. This triggers voltage-gated sodium channels to open, allowing sodium influx into the cell, which propagates the action potential. The action potential then leads to muscle contraction.

Explanation:

An action potential on a muscle cell is initiated through a complex sequence of events. First, a neurotransmitter called acetylcholine (ACh) is released from the motor neuron and binds to receptors on the muscle cell membrane or sarcolemma. This binding opens up a channel in the ACh receptor, allowing positively charged sodium ions to enter the muscle fiber.

This ion movement causes the muscle fiber to depolarize, or become less negative, changing the membrane potential. As the membrane depolarizes, another set of ion channels, the voltage-gated sodium channels, are activated and trigger an influx of more sodium ions into the muscle fiber.

This flooding of sodium ions propagates an action potential, or electrical signal, across the entire muscle cell membrane. This action potential then interacts with the sarcoplasmic reticulum to release calcium ions, leading to muscle contraction.

5 The diagram below represents two processes thatoccur in organisms. A characteristic representedby X is common to both of these processes.ActiveDiffusionXTransportA characteristic that the two processes have incommon is that each process(3) uses oxygen(1) uses ATP(2) requires enzymes(4) moves molecules

Answers

Answer: Move substances

Explanation:

The process of diffusion and active transport are some of the process inside the body which helps in transportation of the materials from one place to another.

The substances move a region of higher concentration to lower concentration in case of diffusion and with the help of energy the molecules moves from lower concentration to higher concentration.

The correct answer is option D.

diffusion doesnt required energy or atp enzyme, and oxygen. it just need different concentration between two substance and semipermeable membrane if it is diffusion in water that usually we call as a osmosis.

otherwise they both move molecules, certain molecules somtime in transport active

A closer cross-section view of a stem revealed continuous rings along the interior of the stem. Which type of stem could it be?. . A. Herbaceous dicot stem. B. Woody dicot stem. C. Monocot stem

Answers

"Woody dicot stem" is the one among the following choices given in the question that is the type of stem described in the question. The correct option among all the options that are given in the question is the second option or option "B". I hope that this is the answer that has come to your desired help.

The right option is; B. Woody dicot stem

Woody dicot stem is a type of dicot stem that is made up of a cork, epidermis, cork cambium, xylem, phloem, cortex, vascular cambium, and pith. When woody dicots becomes mature, the vascular bundles connect together to form continuous rings along the interior of the stem. During winter in each year when there is reduced growth in plants that have woody dicot stems, there is production of annual rings which can be counted to determine the age of the plant.

According to the phylogenetic tree, from which domain did Eukarya evolve?

Answers

According to the phylogenetic tree, the Eukarya, or the Eukaryotic cells, rose around 2 billion years ago, give or take a fer hundred million, from the Archaea domain. The Archaeas are single-celled organisms that belong to the Prokaryotic type, meaning that the Eukarya are more complex since they have a nucleus and build together multi-cellular organisms.

Archaea and Eukarya.

On the basis of the information provided in the question, the ultimate branch of the phylogenetic tree starts with the line of Eukarya and then possesses the species of the Archaea division that comprises those prokaryotic species, which thrives in extremely tough environmental scenarios.

As the last branch possesses species of two domains, that is, Eukarya and Archaea and it starts with Eukarya and afterward holds the species of Archaea, which shows that both Eukarya and Archaea are associated genetically.

How are plate tectonics formed? How do we know they exist (list 4-5 pieces of evidence)? And what are the different boundries?

Answers

Tectonic plates are the result of the mantle cooling on the surface. At plate boundaries or "zones" occure, there are different reactions along the edges of them. Divergent is when two plates move away from one another allowing fresh molten rock to flow to the surface. This results in a volcano. Covergent boundaries are when plates come together, resulting in mountain ranges. Transforming boundaries are when they slide up against each other causing earthquakes. More examples of proof of plate tectonics is the changing of Pangea into the world as we know it and subduction zones that reveal fossils that were deeply buried under layers of earth.
