This is because the stomach has a lining that protects it from being digested. The stomach lining is made up of epithelial cells, which produce and secrete a bicarbonate-rich solution that coats the mucosa.

Sergio [31]

Answer:

If an inhibitory synapse fires at the same time and at the same distance from the initial segment as an excitatory synapse of the same intensity there will be no changes in the potential in the firing zone.

Explanation:

Under normal conditions, the transmembrane potential depends on the ionic charges present in the intracellular and extracellular spaces. The extracellular space load is usually positive and in the cytoplasm is negative.

  • <u>Depolarization</u> occurs by opening ion channels that allow sodium to enter the cell, making the intracellular space more positive.
  • An opening of potassium channels releases this ion to the extracellular space, leading to <u>hyperpolarization</u>.

An excitatory synapse is one capable of depolarizing a cell and boosting the production of action potential, provided it is capable of reaching the threshold of said potential.

On the other hand, an inhibitory synapse is able to hyperpolarize the cell membrane and prevent an action potential from originating, so that they can inhibit the action of an excitatory synapse.

The interaction between two synapses, one excitatory and one inhibitory, -called synapse summation- will depend on the strength that each of them possesses. In this case, the intensity of both synapses being the same, there will be no changes in the membrane potential in the firing zone.

I am Lyosha [343]

Answer:

The correct answer is CSA.

Explanation:

Community Supported Agriculture (CSA) is an alternative model for the distribution of agricultural products directly from the farmer to the consumer, it consists of a group of people who form a cooperative to grow and consume food. Through this socio-economic model, consumers lend their support to producers, in exchange for a direct and regular delivery of biological products, that is, producers and consumers support each other and share the benefits and risks of food production.

Which of the following is a decomposer?
faltersainse [42]

According to an answer from another and a bit of my own research;

A decomposer is exactly what it sounds like, an organism that decomposes something and feeds off of it. You can eliminate the answers "Owl" and "Hawk" from a first glance as they are both consumers. Looking at it again, an "Ant" is <em>not </em>a decomposer, but rather, a consumer just like your other two options. This leaves "Fungus", something that decomposes it's food.

Please forgive me if I'm wrong. Feel free to ask for more information and I will scour the internet to see what I can find. <3

What would happen without the magnetic field?
telo118 [61]

Explanation:

The Earth's magnetic field protects us by deflecting much of the incoming solar radiation. Without it, our atmosphere would be stripped by solar winds.

Satellites can and do suffer damage from solar storms, and without Earth's magnetic field, every electronic device could be exposed to high-energy particles from cosmic rays and the solar wind. If Earth lost its magnetic field, there would be no magnetosphere and no line of defense, even from weaker solar storms
