Answer: By definition, if the atomic number =
7
, then there are 7 protons, 7 electrons, and 8 neutrons!
Explanation:
The atomic number is by definition the number of protons, positively charged particles, contained within the atomic nucleus. So if there are 7 protons, there MUST be 7 electrons, 7 negatively charged particles. Why? Because matter is electrically neutral, and positive and negative particles must be equal.
Electrons have negligible mass; the mass number depends on the number of protons contained within the nucleus, PLUS the number of neutrons. Given that we have 15 N
, there must be 8 neutrons contained within the nucleus. does this help?
<span>Like watercolor, the substance that can be applied in a translucent wash, that is well suited to large areas of flat, saturated color is called a gouache. It makes the colors opaque like an inert pigment which is colorless in paints. </span>
The most likely hypothesis that you can derive base on the observation that the wash enzymes did not perform as expected is that the wash enzymes's three dimensional structure of protein may have been altered. Altering its structure may cause the enzyme to perform differently as before even if it has the same physical feature.
Answer:
Changes in the genes DNA sequence can change proteins by altering their amino acid sequences, which may directly affect one's phenotype.
