Answer:a long period of time with severe cold and lots of hard ice
Explanation:
Scientists have recorded five significant ice ages throughout the Earth’s history: the Huronian (2.4-2.1 billion years ago), Cryogenian (850-635 million years ago), Andean-Saharan (460-430 mya), Karoo (360-260 mya) and Quaternary (2.6 mya-present).
William Cuthbert Faulkner was an American novelist and short-story writer best known for his novels and short tales set in the fictitious Yoknapatawpha County, which was centered on Lafayette County, Mississippi, where Faulkner spent a good portion of his youth.
<h3>What is the central message of Faulkner's speech?</h3>
Faulkner's "Speech Accepting the Nobel Prize in Literature," asked writers to be cognizant of what is "essential" while humanity faced atomic anxieties and fears. The speech was a declaration that, despite humanity's predicament, we would not only endure but also triumph.
The fundamental point of Faulkner's Nobel Prize acceptance speech is that writers must overcome the anxiety that prevailed during the Cold War; they must rise above this fear and focus on the only thing worth writing about, which is "the human heart in a struggle with itself."
Thus, Option A is the correct option.

Allele frequency is used to display the genetic diversity of a species population .
Explanation:
To calculate the frequency of the recessive allele we use the
THardy-Weinberg equation
p² + 2pq + q²
p+q=1
p is the frequency of the homozygous dominant genotype
q is the frequency of the homozygous recessive genotype
2pq is the frequency of the heterozygous genotype.
Total number of individuals = 45 + 30+ 25 = 100
So, the frequency of recessive trait = 25/100 =0.25.
Thus, the value of q² = 0.25
So, q would be equal to square root of 0.25 which comes out to be 0.5
