Answer:
As heat is added to solid water, the temperature increases until it reaches 0 °C, the melting point. At this point, the phase change, added heat goes into changing the state from a solid to liquid. Only when this phase change is complete, the temperature can increase .
Solid → Liquid: Melting or fusion
Solid → Gas: Sublimation
Gas → Liquid: Condensation
Explanation:
If two populations are merged, each with different frequencies of an allele at a locus, and random mating occurs immediately, how long will it take to achieve a hardy–weinberg equilibrium in the new population?.
If two populations with different frequencies of an allele at a locus randomly mate, then only ONE generation will take to achieve Hardy–Weinberg equilibrium. This principle is used in population genetics.
The Hardy–Weinberg equilibrium is a principle used in population genetics to calculate allele and genotype frequencies in a population.
The Hardy-Weinberg equilibrium states that allele and genotype frequencies in a population will remain constant from one generation to the next in absence of different evolutionary forces.
The evolutionary forces that may alter the Hardy-Weinberg equilibrium include natural selection, mutations, nonrandom mating, genetic drift, and gene flow.

Researchers are investigating the effect of ph level in water on the breeding habits of the moon jellyfish. As part of a laboratory experiment, they will randomly assign one of three treatments, low ph , medium ph , or high ph , to the water in the tanks that hold the jellyfish.
In this experiment randomization tends to minimize the effects of uncontrolled variables, such as water temperature, so that such factors are not confounded with the treatment effects.
In an experiment, variables are carefully controlled in order to ensure the reliability of the results. Usually, treatments are assigned randomly to experimental units. Randomization refers to the assignment of experimental units to groups by chance.
Randomization is important in this experiment because it tends to minimize the effects of uncontrolled variables, such as water temperature, so that such factors are not confounded with the treatment effects.
Missing parts;
Which of the following is the best reason for the random assignment of a treatment level to an experimental unit?
A. Randomization tends to minimize the effects of uncontrolled variables, such as water temperature, so that such factors are not confounded with the treatment effects.
B. Randomization will make up for improper experimental design, data collection, and analysis.
C. Randomization makes the analysis easier since the data can be entered into the computer in any order.
D. Randomization is required by statistical consultants before they will analyze the experiment.
E. Randomization means that the experiment would not need to be replicated

Let f be the function defined by f(x)=x3+x2+x. Let g(x)=f−1(x), where g(3) = 1. What is the value of g'(3)?.
Quick review of the inverse function theorem:
By definition of inverse function,
f(f⁻¹(x)) = x
Differentiating both sides with respect to x using the chain rule gives
f'(f⁻¹(x)) • (f⁻¹)'(x) = 1
so that the derivative of the inverse is
(f⁻¹)'(x) = 1 / f'(f⁻¹(x))
Now if f(a) = b and a = f⁻¹(b), then the theorem says
(f⁻¹)'(b) = 1 / f'(a)
so that
g'(3) = 1 / f'(1)
We have
f(x) = x³ + x² + x ⇒ f'(x) = 3x² + 2x + 1 ⇒ f'(1) = 3 + 2 + 1 = 6
and so
g'(3) = 1/6

Energy released by the electron transport chain is used to pump h+ into which location in eukaryotic cells?.
Answer:
Energy released by the electron transport chain is used to pump H+ into the mitochondrial intermembrane space - Option D-.
Explanation:
There exist three proteinic complexes immersed in the internal mitochondrial membrane. These complexes have the electron transporters and the enzymes necessary to catalyze the electron transference from one transporter to the other. In complexes, I and III released energy by electrons provokes changes in membrane transport protein conformation. These changes make possible the protons transport against their concentration gradient, going from the mitochondrial matrix toward the intermembrane space. The protons concentrations difference between the matrix and the intermembrane space represents released energy.
You are going to write an essay about the life of a person whom you admire. Which two organizational aids could you use, and why?.
Answer:
Organizational aids are tools that allow an author to help the reader understand and follow the flow of information and ideas within a text. They provide a framework for organizing and connecting what has been written into a cohesive whole.
Explanation:
Two organizational aids that could be used to write about the life of someone whom you admire would either be chronological order or cause-and-effect. The chronological order might be used because the author may want to inform the reader about key events within the person's life, and this organizational aid would help to accomplish that goal. Using cause-and-effect could also work well because it could show how certain events were caused by other events, which ultimately led to the outcome of certain moments in the person's life.
Answer:
You can use a sequence chart or a timeline. Both organizational aids allow you to present the events of the person's life in order of occurrence.
