How it is possible for some one to test negative on a simple urine test and positive on the standard test?
Pregnancy tests measure the level of hcg in your body. When you are pregnant, and as your pregnancy progresses, your hcg level rises. When you take a urine pregnancy test and it comes back negative, the level of hcg is not high enough to register on the test. When the quantitative serum pregnancy test is positive, it is a more acurate reading of how far along in your pregnancy you actually are.

What is total positive charges and negative are equal?
When the total positive charges are equal to the total negative charges in an atom or a molecule, the overall charge is neutral. This means that the number of protons (positive charges) is equal to the number of electrons (negative charges), resulting in a balanced electrical charge.
Is dextrose a cation or anion?
Dextrose is a neutral molecule, not a cation or anion. It is a simple sugar also known as glucose and does not have a net positive or negative charge.

What are the Benedicts test results for glucose?
Benedict's test is a simple chemical test used to detect the presence of reducing sugars like glucose in a solution. The test result is positive if a brick-red precipitate forms, indicating the presence of reducing sugars. If the solution remains blue, it indicates a negative result.
What is the positive reaction color for simple sugar?
The positive reaction color for simple sugars like glucose in Benedict's test is a brick-red precipitate. This color change indicates the presence of reducing sugars, which react with the copper ions in Benedict's solution to form the red precipitate.

How do you multiplies and divides integers?
Multiplying and dividing integers is real easy. All you have to do is do regular dividing and multiplying keeping in mind these simple rules: RULES: 1: When multiplying or dividing integers, when the numbers are a positive, positive they equal a positive. When the numbers are negative, negative they equal a positive. In other words, same signs equal positive. 2: This rule is very similar to the rule above. The only change is that when the signs are different, they equal a negative. ( negative, positive= negative, positive, negative= negative.) Please correct me if I'm wrong. Multiply integers- my notes from class positive x positive= positive positive x negative= negative negative x negative= positive Divide integers- again my notes from class positive divided by a positive= positive negative divided by a negative= positive negative divided by a positive= negative Dividing integers are simple if the number has a different sign than the other it is always negative but if they have the same sign its always positive ex. -20/5=-4 ex. -20/-4=-5

What is your question?
How can you tell which is positive and which is negative on a speaker hookup?
Depending on colours of course black is usually negative and the other colour (generally red but depends) is positive. Get a D-cell Battery. Now get two pieces of speaker wire. hold one wire on the positive terminal of the battery and hold the other on the negative side of the battery. touch the wires to the positive and negative posts on the speaker. if the cone moves out ward the positive and negative are correct if it moves inward then the positive and negative are reversed (out of phase.) this simple test will allow you to see which terminal is which.
