.
Answers
The temperature gradient between points A and B is 0.1°C/m and keeping other conditions constant, if the mantle and the crust were closer to each other then the temperature gradient between the two would increase.
The temperature gradient between points A and B is 0.1°C/m. This means that for every meter traveled between the two points, the temperature decreases by 0.1°C. Therefore, the temperature difference between the two points can be attributed to their distance apart.
If the mantle and the crust were closer to each other, the distance between them would decrease. As a result, the temperature gradient between the two would increase. This is because a shorter distance would mean that there is less space for the heat to dissipate, leading to a greater temperature difference over a shorter distance.
The exact increase in temperature gradient would depend on the new distance between the mantle and the crust. However, it can be predicted that the temperature difference between the two points would increase as the distance between them decreases.
In summary, if the mantle and the crust were closer to each other, the temperature gradient between the two would increase. This would lead to a greater temperature difference over a shorter distance.

Why is the boiling point of nonane so high?NaCl has a greater boiling point than MgO because its ions are wider apart from one another.Due to its longer carbon chain than octane, nonane will have a higher boiling point. Since octane branches less than 2,2,3,3-tetramethylbutane, it has a bigger "surface area" and stronger van der Waals forces, which will cause it to boil at a higher temperature.London dispersion forces are stronger in liquid I2 because I2 molecules have more polarizable electron clouds than Br2 molecules do.Distillation.

What feature about water gives it such unique properties?
Its polarity and bond angle
Water being made up of oxygen and hydrogen
Water being able to dissolve substances
Water being in all cells
Answers
Its polarity and bond angle makes water unique properties.
The structure of water molecules is twisted and polar, with partial positive charges on the hydrogens and partial negative charges on the oxygen. This is because oxygen attracts electrons more effectively than hydrogen since it is more electronegative. A great solvent is a water.
Cohesion in water is caused by its polarity. The forces that induce or permit similar molecules to stick together are referred to as cohesion. Water has cohesiveness because its molecules naturally desire to adhere to one another.
When water is not boiling into a gas or freezing into a solid, it is in a liquid condition. When it is liquid, water has the lowest density.

Different kinds of substances have different properties. Compare and contrast the electrical properties of salts, metals, and acids.
Answers
Salts, metals, and acids are three different types of substances exhibiting unique electrical properties.
Thus, salts are ionic compounds and exhibit electrical properties as they have both positively charged ions and negatively charged ions. They can dissociate in solution into their constituent ions to conduct electricity, but they can not conduct electricity in the solid state.
Like salts, metals also conduct electricity due to their free-moving electrons. They have high electrical conductivity and are used in electrical wiring and other applications. Acids release hydrogen ions when dissolved in water which allows them to conduct electricity because the hydrogen ions move freely and carry an electrical charge when acids are dissolved in water, thereby, exhibiting electrical properties.

Both men and women conceived during the widespread famine of the Dutch Hunger Winter were more likely to be obese by age 5050 and more likely to die from stroke or cardiovascular disease. They also experienced more cognitive decline later in life. Fifteen genetic loci associated with growth and metabolic disease were compared between siblings prenatally exposed to the famine and those siblings who were not prenatally exposed.
1. What evidence suggests that these are epigenetic effects?
a. missense mutations within genes encoding histone proteins
b. single nucleotide polymorphisms within loci involved in growth and metabolic disease
c. transposon insertion into loci involved in growth and metabolic disease
d. changes in the methylation patterns of loci involved in growth and metabolic disease
2. Which additional pieces of evidence would help to demonstrate that these effects are due to epigenetic changes?
a. changes in the post-translational modification of metabolic enzymes
b. differences in the expression of metabolic genes
c. mutations in the DNA regions associated with cardiovascular health
d. changes in histone acetylation patterns
Answers
Answer:
1. d. changes in the methylation patterns of loci involved in growth and metabolic disease
2. b. differences in the expression of metabolic genes
d. changes in histone acetylation patterns
Explanation:
Epigenetics refers to the study of heritable changes in gene expression which are not dependent on DNA sequence. Epigenetic mechanisms involve DNA methylation, histone modifications (acetylation, methylation, phosphorylation, etc) and regulatory non-coding RNA (ncRNA) pathways. These epigenetic mechanisms work together and mutually reinforce each other in order to modulate gene expression (either by activating or suppressing gene expression). In consequence, transcriptome data (e.g., genes differentially expressed in particular tissues/cells or stages of development) is an important piece of evidence indicating the existence of epigenetic modulation.
The evidence that suggests that these are epigenetic effects is that changes in the methylation patterns of loci are involved in the growth and metabolic diseases. So, the correct option is D.
What do you mean by metabolic diseases?Metabolic diseases are diseases that are caused due to inefficient metabolic processes. Some of them are Krabbe disease, maple syrup urine diseases, etc.
The additional pieces of evidence would help to demonstrate that these effects are due to epigenetic changes including changes in the histone acetylation patterns. So, the correct option is D.
Epigenetic changes refer to the study of change in gene expression which is caused by a mechanism other than the change in the DNA sequence. It caused reversible changes that affect the expression pattern of the gene. It is passed from cell to cell via mitosis.
Therefore, above are both the questions that are briefly described one by one.

The interior of the phospholipid bilayer is _______ meaning it repels polar molecules, such as water
Answers
The cell membrane's inside is hydrophobic, meaning that water won't cling to it. In order to effectively separate fluid inside the cell from fluid outside the cell, phospholipids form a two-layer cell membrane.
Why do polar molecules repelled by the phospholipid bilayer?Large hydrophilic polar or ionic molecules find it difficult to pass through the phospholipid bilayer. The cell membrane prevents the passage of any size charged atoms or molecules.
What component of the phospholipid bilayer is water-repellent?While the tails (the lipid component) are non-polar, the heads (the phospho part) are polar. The tails, which face the inside of the cell membrane, are "hydrophobic" (fearful of water), whereas the heads, which make up the exterior and inner linings, are "hydrophilic" (lovers of water).

what is the resting phase of the cell cycle called?
A. Prometaphase
B. Mitosis
C. Interphase
Answers
The resting phase of the cell cycle is called interphase.
Interphase is a critical stage in the cell cycle during which the cell prepares for division by going through different activities such as growth, DNA replication, and protein and organelle production. It is the longest phase of the cell cycle and is separated into three subphases: G1 (Gap 1), S (Synthesis), and G2 (Gap 2).
The cell develops in size, synthesises RNA and proteins, and performs its regular duties during the G1 phase. The cell enters the S phase after passing through the G1 checkpoint. The DNA of the cell is reproduced during the S phase, resulting in the production of two identical copies of each chromosome.
This ensures that during cell division, each daughter cell receives a complete set of genetic material. The cell enters the G2 phase after DNA replication, where it continues to expand and prepares for mitosis.
Interphase is not a real resting phase because the cell is actively engaged in multiple cellular functions. However, because the cell is not visibly dividing at this period, it is commonly referred to as the resting phase.
