Following the Hardy-Weinberg equilibrium theory, in a population of six million people, 1,080,000 individuals are healthy and carriers (heterozygous) for the trait.
What is the Hardy Weinberg equilibrium?The Hardy-Weinberg equilibrium is a theory that states that populations in equilibrium get the same allelic and genotypic frequencies generation after generation.
These populations do not evolve. No evolutive forces are acting on them.
Assuming a diallelic gene, frequencies are
Allelic frequencies
p is the dominant allele frequencyq is the recessive allele frequencyGenotypic frequencies
p² is the frequency of the homozygous dominant individualsq² is the frequency of the homozygous recessive individuals2pq is the frequency of heterozygous individuals
In a population in equilibrium,
p + q = 1p² + 2pq + q² = 1We will consider these equations to solve the problem.
Glucose-6-phosphate deficiency is an autosomal recessive disease.One out of every hundred people of the affection. So this is the homozygous recessive genotypic frequency.Because we have the frequency of the homozygous recessive genotype, we can get the allelic frequency.
q² = 1/100 = 0.01q = √q² = √0.01 = 0.1Now, by clearing the equation p + q = 1, we can get the dominant allele frequency. And then, the frequency of the homozygous dominant genotype.
p = 1 - 0.1 = 0.9p² = 0.9² = 0.81Finally, we can get the frequency of the heterozygous genotype
2pq = 2 * 0.9 * 0.1 = 0.18The number of individuals with each phenotype in the population is,
0.81 * 6,000,000 = 4,860,000 individuals are healthy not carrier0.18 * 6,000,000 = 1,080,000 individuals are healthy carriers. 0.01 * 6,000,000 = 60,000 individuals have the disease.In a population of six million people, 1,080,000 individuals are healthy and carriers (heterozygous) for the trait.

Form a hypothesis to explain the earthquakes that preceded the eruption of Mount St. Helens' 2004 eruption.
The eruption was preceded by a two-month series of earthquakes and steam-venting episodes produced by an injection of magma at shallow depth below the mountain.
What preceded the eruption of Mount St. Helens' 2004 eruption?A wave of diminishing pressure traveled down the volcanic conduit until it reached the underground magma reservoir. The magma reservoir then started to rise, produce bubbles (degas), and erupt explosively, which drove a Plinian eruption that lasted for 9 hours. Mount St. Helens's summit crater saw a steam-blast eruption recently.

How does the tortoise get nitrogen?
The tortoise got nitrogen eating the plants.
What is nitrogen ?
There are numerous gases in our atmosphere. But did you realize which gas makes up the greatest part of the composition.Nitrogen Gas is what it is. In terms of atmospheric composition, it contains 78% nitrogen, 21% oxygen, 1% argon, and traces of carbon dioxide, krypton, and hydrogen.
Nitrous oxide, neon, helium, methane, xenon, ozone, iodine, carbon monoxide, and ammonia are also present. As the most prevalent element in the Earth's atmosphere, it is also the primary ingredient of all biological stuff.
Herbage provided more dry matter and energy to tortoises than grass. Although herbage provided more N and retained more of it than grass, amino acid compositions and actual N digestibilities were comparable between diets. Herbage had more Ca than grass, particularly in respect to P (Ca:P 14.5 vs. 1.9), although this was mitigated by the herbage's decreased absorption of Ca. K intakes from herbage were higher than from grass, and this was related to the digestive loss of Mg from herbage. The low Na concentration of both forages resulted in net Na losses.

2) Jessica and Maria are both making slime with different recipes. Jessica’s recipe calls for \large 1\frac{1}{2} cups of flour and Maria’s recipe calls for \frac{2}{3} cups of flour. How many cups of flour will they need in order to make both of their batches of slime?
With the help of fraction addition it is found that 13/6 cups of flour will be needed to make both of Jessica and Maria's batches of slime.
How are fractions added?
There are three easy steps to add fractions:
Step 1: First, ensure that the denominators (bottom numbers) are the same. If the denominators are not same take their LCM to make the denominators same.
Step 2: Add the higher numbers (the numerators), then multiply the result by the denominator.
Step 3: Simplify the fraction.
Amount of flour required in Jessica's recipe = 1 and 1/2 cups (mixed fraction) = 3/2 cups Amount of flour required in Maria's recipe = 2/3 cups.
Here the denominators of the fractions 3/2 and 2/3 are not same, therefore we need to find the LCM (lowest common factor) of 2 and 3 in order to make the denominators same for addition. The LCM of 2 and 3 is 6.= 3/2 + 2/3 = 9/6 + 4/6 = 13/6

What would be the evidence to support this.
The evidence that would support the claim the survival trait became common in the bed bug population because their immune system got used to the chemicals causing them to mutate in order to survive is the change in the allele frequency for the mutated gene variant in the population across generations.
What is a genetic mutation?A genetic mutation can be defined as any alteration in the genetic material of an organism that may be associated with a change in the phenotype when this mutation affects a gene that encodes for such trait.
A mutation may be beneficial, deleterious or neutral depending on the resulting phenotype and it may produce a positive change in the allele frequency in the case of positive germinal mutations.

The age of the sample from the half life is 2.1 * 10^9 years.
What is the age of the sample?We know that when radioactivity is taking place, the parent nucleus would disintegrate and the daughter nucleus is formed. We can know the amount of the parent and daughter isotope as it is in the question.
We mow need to find the age of the sample from;
N/No = (1/2)^t/[tex]t_{\frac{1}{2} }[/tex]
N = Number of atoms that remain after time t
No = Number of atoms originally present
t = age of the sample

Flowers are a plant's reproductive organs that participate in sexual reproduction. It contains the female reproductive organ known as a gynoecium and the male reproductive organ known as an androecium. Through pollination, the androecium's pollen grains are delivered to the gynoecium's stigma. The male gametes are transferred from the pollen grain to the female gamete that is already present in the ovary through the pollen tube as it grows and develops. The zygote is created when the male and female gametes combine. The ovules become seeds, and the ovary becomes fruit. When these seeds are spread in the soil, they germinate and produce new plants.
