If you have a 20% sugar solution and a 45% sugar solution how does the 20%
solution compare to the 45% solution?

Answers

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.

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.

Answers

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.

Explanation:

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

Answers

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.

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

Answers

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

30. An anatomist wishes to make detailed comparisons of

medial surfaces of the left and right sides of the brain. This

work requires sections that show the entire medial surface.

Which kind of sections should be ordered from the lab for

this investigation?

Answers

Answer and Explanation: In anatomy, bodies are divided by hypothetical geometric planes to describe location or direction of its structures. These planes are called Planes There are 3 reference planes:

1) Sagittal Plane divides the body into sinister and dexter (left and right) sides.

2) Coronal Plane divides into anterior and posterior portions.

3) Transverse Plane divides into superior and inferior portions.

For the anatomist, to have a section that shows the entire medial surface, should be ordered the Sagittal Plane, more especifically midsagittal (median) plane.

Answers

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.
