Actually when we burn metal salts, we cannot actually really see distinct lines to appear because in reality, they are not really visible to the human eye. There is only a certain range of wavelength of light that our eyes can see.

To state in other way, some metal salts will give off light which has wavelengths that are outside of the visible region of the electromagnetic spectrum.<span> </span>

If you place a 4.00 g effervescent antacid pill into 85 mL (85 g ) of water in a 90 g glass, how much will the glass of water we
nikdorinn [45]

Answer:

The glass of water weigh once the antacid pill has dissolved will be less than the 179 grams due to evolution of carbon dioxide.

Explanation:

Mass of effervescent antacid pill = 4.00 g

Mass of water = 85 g

Mass of glass = 90 g

Total mass of the substances  together : 4.00 g + 85 g + 90 g = 179 g

Effervescent antacid pill , moment it get dissolved in water carbon dioxide gas is evolves and escape from the solutions.

This means that mass of the weight of the glass of water with antacid dissolved in it will be less than 179 grams.

Please help me with science
____ [38]

Answer:

The child with the trait is heterozygous.

Explanation:

It's a little difficult to be sure without wider context.  But my interpretation of both the graphic and the wording, is that the circle represents a person who has the trait, but not necessarily someone who expresses the trait.  The square, on the other hand, seems to represent a person who does not have the trait at all.

Based on that, the squares would be hom-zygous--they possess two copies of a dominant version of the characteristic.  And the circles would be heteroxygous--they possess two different versions, one recessive and one dominant.

Unfortunately, this is actually a poorly constructed question, and if the circles are intended to represent an individual who <em>expresses </em>the recessive trait, then the answer would be that the child is hom-zygous.  But based on the exact wording of the question, the correct interpretation of the graphic should be as I've explained above.
