Genotype is the entire set of genes inherited by and heredity is the observable properties that come from genetics
The rapid depolarization phase
of myocardial contractile cells is due to the Na+ ions. Sodium ions are essential
for regulation of blood and body fluids, communication of nerve impulses, heart
activity, and metabolic purposes. Physiologically, it survives as an ion in the
body. Sodium is needed by
animals but is not needed by plants. The human prerequisite for sodium<span> must be less
than 500 mg per day. </span>
Answer:
The respiratory system and the circulatory.
Explanation:
The respiratory system brings in the oxygen and the circulatory system brings all of the oxygen through out the body.
<span>The correct option from the given options is: "Scientist have determined the composition of Earth's core by using radiometric dating to examine meteorites".
</span><span>To date materials the procedure of radiometric dating or
radioactive dating is used, for example, rocks or carbon, in which trace
radioactive impurities were specifically fused when they were framed. The
strategy looks at the abundance of a normally happening radioactive isotope
inside the material to the abundance of its decay items, which shape at a known
consistent rate of decay.</span>
<span>If each of the pairs of
chromosomes was heterozygous (what gives you the highest potential
number of different gametes), then the number of possible gametes
increases from 4 to 8 for a diploid organism. To figure out how many
are possible, raise the number of homologous chromsomes (2 for a diploid
organism) to the power of the number of chromosomes. So if you have
two different chromosomes (A and B), raise 2 to the 2nd power (or
multiply 2 x 2) and you have 4. If you have chromosomes A, B, and C,
then you have 2^3, or 2 x 2 x 2 = 8.
To show possible combinations, AaBb gives you AB, Ab, aB, or ab. AaBbCc
gives possible gametes of ABC, ABc, AbC, Abc, aBC, aBc, abC, and abc. </span>
