The answer is graded potential<span>. Its made of various action potentials that depolarise the neuron incrementaly, in short interspersed intervals that do not give time for the neurons to return to resting potential. Therefore, the actions potentials, of varying sizes, grade up in sum and when they cumulatively reach the threshold level, they invoke an impulse in the nerve</span>
The answer would be Dopamine
Answer:
It is an answer to a scientific question and is based mostly on research.
Explanation:
Mendel five part hypothesis was also known as the law of segregation. This law explain the how traits are inherited in living organisms. Mendel's theory discovered that there are two alleles for a single gene and that one of these alleles is inherited from each parent, which forms the basis of the trait in the progeny(offspring).
Mendel’s hypothesis was considered true after various experiments and analysis and also answer the question of how the different traits are passed on from parent to progeny. This validates it being an answer to a scientific question and it being based mostly on research.
Explanation:
In a covalent bond, there is sharing of the donated electron by two atomic species having very small electronegative differences between them.
Oxidation is the loss of electrons by a specie and it usually lead to an increase in oxidation number.
Reduction is the gain of electrons by a specie. It leads to a lower oxidation number.
Since there is no actual loss of gain of electrons in a covalent body, the electronegativiy is at work.
Electronegativity is the ability of a specie to draw the shared electrons more to itself in a covalent bond.
- Between two atoms bonded covalently, the more electronegative specie draws the electrons closer.
- This leaves a partial negative charge on it.
- The other electron then becomes partially positively charged.
- We can then say, the more electronegative specie undergoes reduction.
- The less electronegative one undergoes oxidation.

A doctor can use a 2D image model to show where the break is.
When a patient breaks a leg (the break could be as a result of fracture or bone dislocation), the doctor needs to scan the patient in order to determine the exact location of the break and the extent of the injury.
The gamma camera, x-ray machine and PET scanners are some of the devices that can be used to scan a bone.
Each of these devices uses 2D image technology to show the result of the scan.
So, a model that can be used by a doctor to determine the location of the break is 2D image.
