Chemistry
1 answer:
otez555 [7]3 years ago
5 0

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.

(true or false) the electron structure of an atom is determined by direct observation using x-rays.
Mama L [17]

The answer is false. It is because the electron structure of the atom is not determined by using the direct observation of using an x-ray but rather the usage of theoretical modeling and the emission spectra will be useful in observing.

How many protons, electrons, and neutrons does an atom with atomic number 50 and a mass number of 125 contain?
EleoNora [17]

Answer:

a) 50 protons, 50 electrons, 75 neutrons

Explanation:

How many protons, electrons, and neutrons does an atom with atomic number 50 and a mass number of 125 contain?

a) 50 protons, 50 electrons, 75 trons

b) 75 electrons, 50 protons, 50 neutrons

c) 120 neutrons, 50 protons, 75 electrons

atomic number IS the number of protons

atomic mass IS the total of protons + neutrons

so 50 protons

125-50 = 75 neutrons

in a neutral atom,

number of negative electrons = number of positive protons

a) 50 protons, 50 electrons, 75 neutrons
