Answer:
19 protons, 19 electrons, and 3 neutrons
Explanation:
the atomic number is 19 so the protons are the same, 19, and the electrons are the same as the proton, because protons are positive and electrons are negative so they have to balance out and the neutrons ➗ mass number by the atomic number.
Answer:
1.) The total possible combination of alleles for those genes in humans is approximately 70,368,744,177,664. This is trillions of times more combinations than the number of people who have ever lived. This accounts for the fact that nearly everyone, except m0n0zyg0tic twins, is genetically unique.
2.) A hom0zyg0us recessive allele c0mbination contains two recessive alleles and expresses the recessive phen0type. For example, the gene for seed shape in pea plants exists in two forms, one form (or allele) for round seed shape (R) and the other for wrinkled seed shape (r).
4.) If the alleles are heteryg0us recessive, the faulty allele would be recessive and not express itself. Instead, the person would be a carrier. If the alleles are heterozyg0us dominant, the faulty allele would be dominant.

Answer:
Appearing disoriented, such as swimming upside down.
Leaving food uneaten.
White spots on fins or body.
Discolored gills.
Explanation:
Gold Fish are unable to regulate their body temperature, so they are influenced by the temperature around them. If the water is warm, gold fish metabolism accelerates, feeding and respiration increases, and there is a general increase in movement. If the water is cooler, fish become lethargic and tend to be inactive.
Answer:
Hydrogen
Explanation:
It is considered a special element due to its flexibility in giving up & taking in electrons, therefore making it good for organic & inorganic chemistry. Hydrogen has only one proton and one electron and is the only element which has no neutrons. it is considered as the simplest element in the universe and gives a valid reason for it to be the most abundant and common element in the universe.
