When water dissolves a substance, weak charges on water molecules attract oppositely charged portions of the substance, pulling them out into the solution. Which property of water accounts for this occurrence
A) cohesion
B) pH
C) polarity
D) surface tension
Answers
Answer:
C) polarity
Explanation:
The polar nature of water molecules allows it to dissolve like molecules, such molecules are also polar.
In water molecules hydrogen bonds provides a special dipole - dipole attraction. Here, the hydrogen atom is directly joined to a highly electronegative atom(oxygen, nitrogen or fluorine). This leads to a charge separation in which the hydrogen atom has net positive charge and the electronegative one has negative charge. This makes the molecule of water polar. By this property water easily attracts oppositely charged portions of another substance and then pull them into solution.This property of water is polarity of water.
The property of water that is at work as described in the question is polarity.
Water is composed of oppositely charged ends; a positive end and a negative end. These oppositely charged ends are called "dipoles".
The occurrence of dipoles in water makes water a polar molecule. Thus, when water dissolves a substance, weak charges on water molecules attract oppositely charged portions of the substance, pulling them out into the solution. This is possible because of the property of polarity possessed by water molecules.

Viruses and bacteria can infect human cells. Bacteria are living organisms, while viruses are not. How do you think the treatment for viral and bacterial illnesses differ? How do you think they affect healthy body cells? Explain your response. NO PLAGIARISM WILL BE REPORTED IF SO.
Answers
Viral infections cause similar symptoms as bacterial infections. Antibiotics treat bacterial infections but do not treat viral infections. Some antiviral medicines are used to treat viral infections.
The misuse of antibiotics to treat a viral infection contributes to antibiotic resistance.
Antibiotics kill bacteria without damaging the body’s cells. They do so by interfering with how bacteria live and reproduce. Normal body cells work in different ways, so they’re not affected.
While antibiotics are effective in treating bacterial infections, they can also damage the immune system when used incorrectly or too frequently. Therefore, the doctor should prescribe antibiotics only when needed and sparingly.

Answers
The study of cre elements in different species has revealed that there can be significant variation in these elements without causing a significant change in overall gene expression patterns. This is a good example of cryptic genetic variation, which refers to genetic variation that is not readily apparent in an organism's phenotype.
In this case, the variation in cre elements may not affect the expression of the gene in question, but it could still have an impact on other traits or functions that are controlled by the same or related genes. This highlights the importance of considering genetic variation beyond just the genes themselves, and taking into account the regulatory elements that control their expression.
It also underscores the complexity of genetic interactions and the potential for epistasis, or the way in which different genes can interact with each other to produce a particular phenotype. Additionally, competitive binding may play a role in this context, as the variation in cre elements could impact the ability of regulatory proteins to bind to the DNA and control gene expression. Overall, this is a complex and nuanced issue that requires a long answer to fully unpack.

The production of antibodies inside the lymphocytes starts at the ribosome (organelle) by joining amino acids together, creating peptide bonds, and forming the primary level structure polypeptide. The polypeptide bends and folds tertiary in the Golgi apparatus (organelle), to form the next level of structure. For instance, the secondary level of structure is formed by hydrogen bonds to create alpha helix or beta-pleated formations.
In order for an antibody to be released into the blood, a fully formed antibody will move from rough endoplasmic reticulum (organelle) to another organelle named Golgi apparatus to sort and be processed for shipment out of the cell. Antibodies transport from organelle to organelle and to the plasma membrane in a vesicle, which is made out of fatty acids-phospholipids.

what amount of thymine would be found in a double stranded of dna composed of 15% cytosine?
Answers
In a double stranded DNA composed of 15% cytosine, we would expect to find 25 thymine nucleotides out of 100 total nucleotides.
To determine the amount of thymine in a double stranded DNA composed of 15% cytosine, we first need to know that DNA is made up of four nucleotides: adenine (A), thymine (T), cytosine (C), and guanine (G). In DNA, A always pairs with T and C always pairs with G. This means that if we know the percentage of one nucleotide, we can calculate the percentage of its complementary base.
If the DNA is composed of 15% cytosine, then we know that it must also be composed of 35% guanine (since A+T = C+G and the percentages must add up to 100%). This leaves 50% for adenine and thymine combined.
Since A always pairs with T, we know that the percentage of thymine must be equal to the percentage of adenine. Therefore, 50% divided by 2 gives us 25% for both adenine and thymine.
To convert this percentage into a specific amount of thymine, we need to know the total number of nucleotides in the DNA. Let's assume for simplicity that the DNA has 100 nucleotides.
If 25% of the nucleotides are thymine, then we can calculate the number of thymine nucleotides by multiplying 25% by 100, which gives us 25 thymine nucleotides.
So, in a double stranded DNA composed of 15% cytosine, we would expect to find 25 thymine nucleotides out of 100 total nucleotides. Keep in mind that this is just an example calculation and the actual number of nucleotides in DNA can vary greatly depending on the organism and the specific DNA molecule.

Carbon cycle is the process where carbon compounds are interchanged among the biosphere, geosphere, pedosphere, hydrosphere, and atmosphere of the earth.
1) Carbon present in the atmosphere is absorbed by plants for photosynthesis.
2) These plants are then consumed by animals and carbon gets bioaccumulated into their bodies.
3) These animals and plants eventually die, and upon decomposing, carbon is released back into the atmosphere.
4) Some of the carbon that is not released back into the atmosphere eventually become fossil fuels.
5)These fossil fuels are then used for man-made activities, which pumps more carbon back into the atmosphere.
Carbon in the atmosphere is present in the form of carbon dioxide. Carbon enters the atmosphere through natural processes such as respiration and industrial applications such as burning fossil fuels.

allocation of the cost of a natural resource is called
Answers
Allocation of the cost of a natural resource is called depletion.
Depletion is a term used in accounting to refer to the allocation of the cost of natural resources. It can be defined as the cost of allocating the use of natural resources that are not renewable, such as coal or oil, or the resources of a mine or well. The cost of these resources is depleted over time as they are used, and the cost of the resource is allocated to each period in which the resource is used. Depletion is commonly used in the accounting for natural resources, such as oil, gas, coal, timber, and minerals. The cost of these resources is spread over the life of the resource, which is known as the depletion period. During this period, the cost of the resource is allocated to the production that takes place during the period. Just like depreciation and amortisation, depletion is a non-cash expense. It incrementally lowers an asset's cost value through scheduled income charges.

Assuming that cytokinesis has occurred, the products of meiosis II can be drawn as follows:In the diagram above, it is assumed that the cell that undergoes meiosis is diploid (2n) and has four chromatids. It is also assumed that crossing over has occurred during meiosis I. After meiosis I, two cells are produced, each containing half the number of chromosomes as the original cell.
In meiosis II, each cell divides into two daughter cells. The chromatids in each daughter cell are no longer identical because crossing over has occurred, and each chromatid has a combination of maternal and paternal genetic material. The end result of meiosis II is four haploid daughter cells, each with one chromatid from each homologous chromosome.
