Answer:
<em><u>Both </u></em><em><u>parents</u></em><em><u> </u></em><em><u>contributed </u></em><em><u>a </u></em><em><u>recessive</u></em><em><u> </u></em><em><u>allele</u></em><em><u>.</u></em>
<em><u>Both </u></em><em><u>parents</u></em><em><u> </u></em><em><u>were </u></em><em><u>short</u></em><em><u>.</u></em>
this is because a recessive allele will only express itself in the absence of dominant allele
-4
Explanation:
If a radioactive isotope undergoes alpha decay, it's mass number will change by -4.
The mass number of a nuclei is the sum of its number of protons and neutrons.
An alpha particle is similar of a helium atom:
⁴₂He
The atom above is made up of:
mass number = 4
Atomic number = 2
Number of protons = 2
Number of neutrons = 2
Number of electrons = 2
If a substance is undergoing radioactive decay, the mass number of the product will decrease by 4 and the atomic number will decrease by 2.
In nuclear equations, mass and atomic numbers are usually conserved.

Answer:
Chambers
Explanation:
Oxygen-rich blood travels from the lungs to the left atrium, then on to the left ventricle, which pumps it to the rest of the body. The heart pumps blood to the lungs and to all the body's tissues through a sequence of highly organized contractions of the four chambers.
The correct answer is that it's most luminous when it is a giant star. A giant star has bigger luminosity than a dwarf of a main sequence star (sun is one) of the same surface temperature
