Why do nonpolar compounds tend to have lower melting points and boiling points than polar compounds?.
Because of their weak van der Waals interactions, non-polar molecules have the lowest melting and boiling points.
What accounts for the higher melting points of polar molecules?Polar molecules can be drawn to the positive and negative regions of nearby polar molecules in the same way that they are drawn to the positive and negative plates in an electric field. Polar compounds thus frequently have melting points that are higher than those of nonpolar ones.
Which factor accounts for the high melting and boiling points of polar molecules?The underlying idea is straightforward: the stronger the noncovalent connections between molecules, the more heat energy is needed to separate them. Stronger materials have higher melting and boiling points.

How do rainforests reduce carbon dioxide concentration in the atmosphere?
Rainforests sequester and store carbon. Forest ecosystems absorb roughly 2 billion tons of CO2 each year, making them the largest terrestrial carbon sinks on Earth. They capture, or sequester, carbon dioxide from the atmosphere and transform it into biomass through photosynthesis.
About rainforestRainforests are characterized by a closed and continuous tree canopy, moisture-dependent vegetation, the presence of epiphytes and lianas and the absence of wildfire. Rainforest can be classified as tropical rainforest or temperate rainforest, but other types have been described.
Estimates vary from 40% to 75% of all biotic species being indigenous to the rainforests.
There may be many millions of species of plants, insects and microorganisms still undiscovered in tropical rainforests. Tropical rainforests have been called the "jewels of the Earth" and the "world's largest pharmacy", because over one quarter of natural medicines have been discovered there.
Rainforests as well as endemic rainforest species are rapidly disappearing due to deforestation, the resulting habitat loss and pollution of the atmosphere.

Students in a class are studying patterns of inheritance using genes involved in determining the body color and wing shape of Drosophila flies. Each of the genes has only two alleles, one of which is completely dominant to the other.
Each student in the class performed a parental cross between a fly that is true-breeding for ebony body and vestigial wings and a fly that is true-breeding for gray body and long wings. Each student then crossed several pairs of the F1
flies and determined the phenotypes of 500 of the resulting F2
flies with respect to body color and wing shape. The students in the class averaged their data for the frequencies of the four possible phenotypes (Table 1).
The students performed a second cross. The parental cross was between flies that are true-breeding for gray bodies and long wings and flies that are true-breeding for ebony bodies and curly wings. They crossed pairs of F1
flies and determined the phenotypes of the resulting F2
flies. The students found an approximate 3:1
ratio of flies with the dominant phenotype (gray bodies and long wings) to flies with the recessive phenotype (ebony bodies and curly wings). Only a few of the flies expressed the dominant phenotype of one trait and the recessive phenotype of the other trait.
(b) Using the template, construct an appropriately labeled graph, including error bars, to represent the data in Table 1. Based on the data in Table 1, determine whether there is a significant difference between the number of flies in each of the four phenotypes.

Genetics refers to the area of biology that focuses on genes and patterns of gene inheritance over successive generations. Alleles can be divided into two categories: dominant and recessive.
What are three laws of genetics?George Mendel's laws of genetics, also known as Mendel's principles of inheritance, are three laws that explain how traits are passed down from parents to their offspring.The first law is the law of segregation, which states that during the formation of gametes (sex cells), the two copies of each gene (one from each parent) separate from each other, so that each gamete receives only one copy of each gene.The second law is the law of dominance, which states that when different versions of a gene (alleles) are present, one allele will be dominant and will be expressed, while the other allele will be recessive and will not be expressed.The third law is the law of independent assortment, which states that the inheritance of one gene is independent of the inheritance of another gene. This means that the inheritance of one trait does not affect the inheritance of another trait.To learn more about George Mendel's laws refer:

Explanation:
What is the phenotypic percentage of the offspring when two heterozygous tall TT pea plants are crossed?
When two heterozygous tall pea plants (Tt) are crossed, the phenotypic percentage of the offspring being tall or short depends on the alleles they inherit from their parents. The chance of inheriting a particular allele from each parent is 50%.
A Punnett square can be used to determine the phenotypic percentage or the probability of different genotypes and phenotypes in the offspring. A Punnett square for the cross between two heterozygous tall pea plants would look like the picture attached.
As you can see, half of the offspring will be Tt (tall) and half will be tt (short). Therefore, the phenotypic percentage of the offspring is as follows:
Tall: 50% (Tt)
Short: 50% (tt)
It is important to note that even though the parents are heterozygous, they only express the dominant trait (tall) and not the recessive (short) trait. This means that the offspring that are homozygous recessive (tt) will express the short phenotype.

During what phase of mitosis do centromeres divide?
The sister chromatids of each chromosome begin dividing at the anaphase II stage and migrate to the ends of the cell.
Kinetochore microtubule shortening causes separation and migration.
Telophase II precedes Late II.
Anaphase II during meiosis is comparable to anaphase during mitosis. Centromeres appear as contractile regions of chromosomes and play an important role in helping cells break down their DNA during division (mitosis and meiosis). In particular, the area where the cell's spindle fibers attach.
The centromere divides during the late II stage of meiosis II. Thus, during meiosis II, the daughter cell's number of chromosomes remains the same as it was at the beginning of meiosis II or at the end of meiosis I, which is exactly half the number of chromosomes in the original parent and mother cells.

A single base substitution can occur in the first, second, or third position of a codon. Propose which position the point mutation is most likely to go unnoticed.
Why? Use examples from the codon wheel to support your answer.
The first, second, or third positions of a codon can all experience a single-base replacement. What position is the highest likelihood that the point mutation will go undetected? In the third slot, a substitute has the highest chance of going unnoticed.
What would happen if a substitution occurred in the first or second base of a codon?A mutation known as a substitution is one that switches one base for another (i.e., alters just one "chemical letter," for as changing an A to a G). A codon may be changed to one that codes for a different amino acid, which would result in a minor modification to the protein that is made.For instance, twofold degenerate codons can withstand silence mutation rather than Missense or Nonsense point mutations at the third position, whereas fourfold degenerate codons can tolerate any point mutation at the third position, although codon usage bias restricts this in practice in many organisms.If a base substitution takes place in the codon's third position, there is a strong likelihood that a synonymous codon will be produced. The mutation is referred to as silent since the gene's encoded amino acid sequence is unaltered.To Learn more About single-base replacement Refer To:

which part of the eye changes the shape of the lens
The part of the eye that changes the shape of the lens is controlled by the ciliary muscles inside the eye.
The ciliary muscle is a ring of smooth striated muscles present in the human eye. This muscle functions to keep the lens in place, to change the shape of the lens so that light can be focused on the retina, and to produce aqueous humor, which is the fluid that causes the eye to maintain its shape.
How the ciliary muscle works, when the eye looks at objects that are close up, the ciliary muscles of the eye will contract so that the lens will thicken (convex) to capture incoming light. The incoming light is then focused so that it falls right on the retina.
if the ciliary muscle is unable to contract, the eye will not accommodate when looking at objects that are far or near.

How many atoms are in 2.00 moles?
The number of atoms in 2.00 moles is 1.204 × 10²⁴.
The international unit for atoms and molecules is the mole. One mole of a substance is the amount of substance that contains as many elementary particles as Avogadro's number (L), which is 6.02 x 10²³. The number of moles is represented by the symbol n.
1 mole of an element = 6.02 x 10²³ atoms of that element
1 mole of compound = 6.02 x 10²³ molecules of that compound
So that:
number of atoms = moles × Avogadro's number
number of atoms = 2.00 ×6.02 x 10²³
number of atoms = 1.204 × 10²⁴
So, the number of an atom is 1.204 × 10²⁴.

the passages is downs below
A common "parent-daughter" combination that geologists use is radioactive uranium and non-radioactive lead. As shown in the diagram above, uranium is trapped in a newly formed rock. As the rock ages, more and more of the uranium changes into lead.
The age of the rock in years can be found by measuring the rate at which a parent element decays and then measuring the ratio of parent element to daughter element in the rock. The ages in years of the different geological time periods are found by measuring the absolute ages of many rocks from all of the different periods. The absolute ages of some of the different geologic time periods are shown along the right side of the Staircase of Time.
The steps of the Staircase of Time are drawn to be almost the same size, so you might think that the time periods are the same length, but they are not. The absolute ages of rocks taken from the different time periods have shown that the time periods were of greatly differing lengths. Some were very short, like the Quaternary period (only 2 million years), while others were very long, like the Proterozoic Era (almost 2 billion years). According to absolute-age measurements, an accurate representation of the lengths of the major geologic time periods is shown in the time bar at right.
