No. Food can be contaminated with a variety of adulterants - most of which show no signs at all that they are present.
It depends on the type of contamination - but most often, NO. Food contaminated by bacterial food usually looks the same as uncontaminated food. Food contaminated by a fungus may look a bit different. Also many times the difference in appearance is so slight as to not be noticeable unless one looks very carefully and knows what to look for. In general the best protection against contaminated food is proper handling and storage.
The answer is always positive (or 0).
The answer is always positive. If the signs are the same (positive by positive, negative by negative), then the quotient is always positive. If the signs are different (positive by negative, negative by positive), then the quotient is always negative.
It is impossible. The absolute value is always positive.
++ = + +- = - Like signs always give me plus. Unlike signs always give me minus when I multiply! My maths teacher made us learn that! :D
because you are dividing with same signs
Hieroglyphs and the hieratic signs that derived from them were most often written from right to left, but could also be written left to right or vertically downwards. The signs are always neatly grouped into invisible rectangles to make the writing neat and tidy and the signs always face the start of the line. So if the text is written right to left, the signs always face the right; if the text is left to right, the signs all face left.
Scorpio and Cancer are both water signs. In astrology, signs that are within the same element can (but, not always) be able to get along with eachother.
Signs that a Libra woman might like a Capricorn man included flirting, smiling, and always trying to be around the same places that he is at.
The answer will always be Negative in Sign. If they are the same sign, it will always be Positive in Sign.
Not always, no.
