Answer:

The correct answer is - The neuron's intracellular charge must get more positive to meet a certain thresh hold in order to depolarize. If the neuron does not hit that threshold, then the neuron will not fire

Explanation:

In neuroscience, the depolarization of neurons shows the all or none law which is also called as all or nothing response. It states that all action potentials have the same size and the potential or strength of a nerve cell does not depend on the stimulus strength as all are the same size.

If a stimulus reaches a particular threshold cell or fiber will fire so either it will fire or not cross the threshold this is all or nothing response or law and depolarization is an example of it.

DNA has the instructions for making a cell’s blank

9966 [12]

Answer:

Explanation:

DNA contains the instructions needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies.

What force is the sum of all the forces that act upon an object

Vsevolod [243]

The net force is the vector sum of all the forces that act upon an object. That is to say, the net force is the sum of all the forces, taking into account the fact that a force is a vector and two forces of equal magnitude and opposite direction will cancel each other out

The table below shows the amount of carbohydrates in same-size servings of different fruits. Amount of Carbohydrates in Fruit 23

marta [7]

Answer:

As per the data provided, the correct answer would be cherries.

The effect of any food in increasing the blood sugar level can be understood with the help of glycemic load. It takes in the account of both the glycemic index as well as serving size.

It states that the glycemic response of our body depends on both "the type of carbohydrate and the amount of carbohydrate" consumed in a meal.

For example, glycemic response of small size high GI food is the same as that of large size low GI food.

It can be calculated as follows:

$\text{glycemic load} = \frac{\text{glycemic index x net carbohydrate}}{100}$

Hence, glycemic load of apple would be = (38 x 17)/100 = 6.4.

Similarly, glycemic load of cherries, oranges, and watermelons would be 4.18, 10, 8.6 respectively.

Hence, cherries are the fruit which has low glycemic load value of 4.18. So, the glycemic response of this fruit would be low. Hence, it will result increase the blood sugar by the least value.

What part of the nucleotide connects in

ozzi

Answer: The inside of the molecule, the "steps" of the staircase, are made of the nucleotide bases Cytosine, Guanine, Adenine, and Thymine. C bonds to G by three hydrogen bonds. A bonds to T by two hydrogen bonds. A and G are double ringed structures called "purines".
