Phenytoin (sodium channel blocker) and ethosuximide (calcium channel blocker) are anti-seizure drugs that stop seizures from happening. These drugs work by inhibiting electrical impulses (action potentials) from occurring. Explain the importance of sodium and calcium channels on a neuron and and the reasons why action potentials do not occur when these channels are inhibited
Answer:
Phenytoin and ethosuximide are drugs that slow the recovery of the sodium channel during the inactivated state.
That is to say, they prolong the inactivation state of the channel, thus generating that in this way the neuron remains in resting potential and the action potential causing the epileptic attack is not triggered.
On the other hand, these drugs, according to the bibliography of the book "Golan, 3rd Edition, Principles of Pharmacology" have a use-dependent affect capacity, this means that those sodium channels that have more activity will be more affected, in this way Not only is epileptic shock avoided, but if the same happens independently in any neuron, it will not be able to propagate the action potential to its neighboring neurons, therefore the surrounding neurons will not be stimulated and will not be fulfilled. with the sudden rapid discharges that are the most dangerous in some cases of severe epilepsy.
It is important to understand that these drugs affect the ion channels responsible for exciting neurons, that is why by inhibiting them, a constant rest of these neurons is promoted, and they are unable to generate abrupt discharges and dissemination of the electric charge. among them generating epileptic shocks.
The ions in neurons are in charge of indicating or modulating the different neuronal states, if they are inactive, open or closed, they will directly affect the membrane potential, that is, the positive or negative charge of the neuron's membrane.
Explanation:
In order to finish completing the question, these drugs are excreted through the p450 protein, that is why if this excretion system becomes saturated because another drug is consumed that is excreted in the same way, these antiepileptics will remain longer in use. blood and in the body, generating a greater effect and enhancing adverse effects on the central nervous system.

Read the following claim. Life on Earth could not exist without decomposers. What evidence from the article supports this claim? Explain why the evidence supports this claim.
Answer:
Explanation:
It's hard to distinguish facts/ evidence from the article with only the statement ' Life on earth could not exist without decomposers', but taking that into consideration, it's best if you breakdown the information so you properly understand what it means.
Life on earth - refers to evolution of life on earth such as single celled organisms, eukaryotes, prokaryotes, bacteria and so on
could not exist - refers to the inability of it being there, it's presence is basically there/ not there
decomposers - is an organism that breaks down organic materials from dead organisms to obtain energy such as fungi, bacteria, worms and so forth.
You basically need to relate all the information you find in the 'article' to the statement they have made and which i have broken down for you above.

Punnett squares are used to predict the most likely allele combination of a genetic combination.
Punnett squares are used to predict all possible allele combinations of a genetic combination.
Punnett squares are used to predict dominant allele combinations of a genetic combination.
Punnett squares are used to predict recessive allele combinations of a genetic combination.
Answer:
Punnett squares are used to predict all possible allele combinations of a genetic combination
Explanation:
The person above is right
Punnett squares are used to predict all possible allele combination of a genetic combination. Therefore, option (B) is correct.
What is a punnett square?The Punnett square is a diagram in the form of a square that is utilized for the purpose of predicting the genotypes that will result from a specific cross or breeding experiment. Reginald C. Punnett, who came up with the method in 1905, is honored with the naming of this technique. The diagram is utilized by biologists so that they can calculate the likelihood of a future generation inheriting a particular genotype.
A Punnett Square is a useful tool that helps to predict the variations and probabilities that can result from cross breeding. This can be done by comparing the offspring of two different species. This includes the estimation of the likelihood of sexually reproducing humans, animals, and plants.

Help me plz !!!! A cat that weighs 55 N sits on the top of a cat tree. It is 2 m above a 110 N
dog. How does the mass of the animals relate to the force of gravity on
them?
O A. The mass of the 55 N cat is greater than the mass of the 110 N
dog.
B. The 55 N cat has less mass than the 110 N dog.
C. The 55 N cat has the same mass as the 110 N dog when it is in
the cat tree.
O D. The mass of the 55 N cat will be the same as the mass of the 110
N dog after it jumps to the ground.
Answer:
B. The 55 N cat has less mass than the 110 N dog.
Explanation:
Weight of an object refers to the product of its mass and the force of gravity. However, the greater that mass of an object, the greater the weight of that object.
In this case, the cat's weight is 55N while the dog's weight is 110N. This means that the dog has a greater mass than the cat or alternatively put, the 55 N cat has less mass than the 110 N dog.
Note that: if the gravitational effect is removed, the cat will contain lesser mass.

B

If you have a 20% sugar solution and a 45% sugar solution how does the 20%
solution compare to the 45% solution?
Answer:
It is 25% less
Explanation:
That is all i can say
A close comparison of the 20% solution to the 45% solution shows that the 20% solution is actually less than 50% of the 45% solution.
Arithmetically, you discover that the 20% solution is 25% or 0.25 (45% - 20%) less than the 45% solution.Comparatively, you can compute that the 20% solution actually represents 44.4% or 0.444 of the 45% solution (20% x 45%). The same result can be obtained by first dividing 20% by 45% and then multiplying the resulting dividend by 100.Thus, the result of the comparison shows that there is more sugar in the 45% solution than there is in the 20% sugar solution.

How many grams of solute are needed to make 250 mL of a 2.055 M NaCl solution?
30 grams
76.7 grams
300.081 grams
58.44 grams
Answer:
30grams
Explanation:
To calculate the mass (number of grams of the solute) in the solution, we need to calculate the number of moles it contains first. We use the formula;
M = n÷ V
Where; M= Molarity or Molar concentration = 2.055M
n= number of moles= ?
V= Volume = 250mL
Volume in L is 250/1000 = 0.250L
n= M × V
n= 2.055 × 0.250
n= 0.51375moles
The mass is calculated using :
Mole (n) = mass (m) / molar mass (MM)
Molar mass of NaCl = 23 + 35.5
= 58.5g/mol
Mass = molar mass × mole
Mass = 58.5 × 0.51375
Mass = 30.0543
Therefore, the mass is 30grams

. As the volume of the cell increases, how does the surface area to volume ratio (SA/Ve) change?
Answer: Well, you see, As the cube size increases or the cell gets bigger, then the surface area to volume ratio - SA:V ratio decreases. ... When a cell grows, its volume increases at a greater rate than its surface area, therefore it's SA: V ratio decreases.
