The binding of the neurotransmitter to receptors on the motor end plate causes which of the following to occur?

Biology
1 answer:
dmitriy555 [2]3 years ago
4 0

The correct answer is: D) Binding of the neurotransmitter causes chemically gated sodium channels to open in the motor end plate (junctional folds of the sarcolemma) and sodium enters the cell.

The motor neuron cell is connected to muscle cell via synaptic cleft, where neurotransmitter is released. The muscle side of this synapse is called motor end plate. Released neurotransmitter is acetylcholine and it binds to its receptor (ACh receptor) on the motor end plate. As it binds, ion channels open, and Na+ gets into the muscle cell. This event reduces the voltage difference between the inside and outside of the cell and causes  depolarization which creates a wave through the entire muscle cell (its membrane-sarcolema). As a consequence, Ca2+ is released from the sarcoplasmic reticulum which will cause the contraction of the muscle cell.

Identify the products and reactants in a chemical equation. Identify the different types of chemical reactions.
Trava [24]

Explanation:

The products in a reaction are the species on the right hand side of a chemical equation.

The reactants are the species on the left hand side of the equation.

  A  + B ⇒  C+ D

The reactants A and B, products are C and D.

Reactants are the species combining together.

The products are the results of the combination.

Types of chemical reactions;

Combination or synthesis; in this type of reaction, two species combines to give a product or products:

      A  + B ⇒  C+ D

Decomposition or cracking: a specie breaks down into one or more products:

    A ⇒ B + C

Single displacement: one specie replaces another in a reaction:

  A + CD ⇒  AC + D

Double displacement: species replaces another in a reaction:

 AC + BD ⇒  AD + BC

The experimental process of determining the relative location of genes or other segments of dna along individual chromosomes is
Tatiana [17]

The experimental process of determining the relative location of genes or other segments of DNA along individual chromosomes is called Genome mapping or chromosome mapping.

<h3>What is DNA?</h3>

Deoxyribonucleic acid is a polymer made of two polynucleotide chains that coil around one another to form a double helix and which contains the genetic material necessary for all known creatures, including many viruses, to develop, function, grow, and reproduce. Nucleic acids include DNA and ribonucleic acid (RNA). Nucleic acids are one of the four main categories of macromolecules that are necessary for all known forms of life, along with proteins, lipids, and complex carbohydrates (polysaccharides).

Because the two DNA strands are made up of simpler monomeric units termed nucleotides, they are referred to as polynucleotides.

3. Did the moths change color over this time period?
AURORKA [14]
I believe that I know what you are talking about however a better layout or source would be nice.
3:I’m sorry I’m not really sure how to answer this one but I’m going to assume that you mean from dark to light. So they liked this time period because the trees were darker due to pollution, this made the darker moths survive from predators while the lighter color moths would be eaten, over time, natural selection would do its course and the whole population of moths would be dark.
4:Well I kind of already answered this but the majority of them were dark because the lighter ones would not be camouflaged therefore making them be easier target for predators and makes the darker moths breed out the lighter ones.
5:Well giraffes cannot live without food so the giraffes with shorter necks would slowly die off making it so only the long necked one would be able to reproduce with babies which would also have long necks, over a long course of time, the shorter necks would be completely gone.
6:Well I wouldn’t say they “grow” longer necks. It’s more like genetic mutation made it so random giraffes would get longer necks then others, since giraffes live in an environment where they have to have long necks only the giraffes with that genetic mutation would survive, and as a said, the longer neck giraffes could only breed with the other Long necked giraffes cause those are the only ones that could survive.
