In a rooted phylogenetic tree, each node ... phylogenetic tree that explicitly represents evolutionary time through its branch spans. A spindle diagram (often called
Answer: The frequency of brown beetles is 0.32.
Explanation: The frequency of A1 allele is 0.8. As p+q=1, or the sum of dominant and recessive frequencies equals 1 or 100%:
1 - 0.8 = 0.2
In Hardy-Weinberg principle,

2pq represents the frequency of heterozygote individuals, so:
genotype A1A2 = 2*0.8*0.2 = 0.32.
Thus, the frequency of brown beetles (A1A2) in the population is 0.32.
The process of having to apply a tourniquet in a person’s
leg due to injury and with continuous bleeding in order to stop it is called
hemostasis. This process, the hemostasis, is a process of having to stop the
flow of blood which is important in scenarios like this, in order for the
patient to prevent of having to lose more blood.
From what I've learned so far about hibernation and migration...
Some animals migrate to head towards warmer weather and plentiful food.
Some animals hibernate to conserve energy so they can survive the harsh winters with little to no food at all.
I hope this helped you answer your question.
