A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by the given equation. Using this equation, find the time that the rocket will hit the ground, to the nearest 100th of second.
y=-16x^2+129x+119
y=−16x

<span>The abundance and variety of fossils in Phanerozoic rocks have allowed geologists to decipher in considerable detail the past 600 million years or so of the Earth’s history. In Precambrian rocks, however, fossils are rare; thus, the geologic record of this important part of the Earth’s history has been especially difficult to decipher. Nonetheless, stratigraphy and radiometric dating of Precambrian rocks have clearly demonstrated that the history of the Earth extends billions of years into the past.</span>

Answer:
Heterozygous for the gene
Explanation:
Alleles are the possible alternative forms of a gene. An organism having two identical alleles of a gene is said to be homozygous for that gene. On the other hand, an organism having two dissimilar alleles for a gene is heterozygous for that gene.
For example, let's suppose that I^A and I^B are the two alleles for ABO blood type in humans. Here, an individual with one copy of I^A and one copy of I^B would be heterozygous for ABO blood type. On the other hand, genotypes I^AI^A and I^BI^B are homozygous for the ABO blood type gene.
