Step 1.

Write down the experiment data.

- tube containing water;

- alodea (photosynthetic organism);

- 10 g of sodium bicarbonate;

- light source.

Step 2.

Why bubbles are formed on the leaves of the alodea?

The experiment have all the condictions for photosynthesis, since it provides: water (that is in the tube), CO2 (because of the dissolved sodium bicarbonate), light (because of the string light source). Therefore the most ogical explanation for Alice experiment results is: the bubbles formed as the elodea plant releases oxygen from the elodea leaves, that because with all the elements in the experiment the plant can do a normal photosynthetic process that way realing oxygen in the tube and forming bubbles of "air".

The correct option is (d). During anaphase, movement of the chromosomes would be most affected by a drug that prevents shortening of microtubules. This is because it is the shortening of microtubules that pulls the chromosomes towards the poles of the cell in order to make the two sets of chromosomes separate.

During anaphase, movement of the chromosomes would be most affected by a drug that prevents shortening of microtubules. This is because it is the shortening of microtubules that pulls the chromosomes towards the poles of the cell in order to make the two sets of chromosomes separate. In this process, the sister chromatids are pulled apart, one towards each pole and the result of this separation is that each pole now has a complete set of chromosomes that will be used to form two identical nuclei. Chromosomes are structures in the nucleus of a cell that contain genetic material in the form of DNA. DNA is the genetic material that is passed on from parents to offspring and carries the information that determines the characteristics of the organism. Chromosomes are responsible for the transmission of this information from one generation to another. The nuclear envelope is the double-layered membrane that surrounds the nucleus of a cell. It separates the contents of the nucleus from the cytoplasm and regulates the flow of molecules in and out of the nucleus. The formation of the nuclear envelope is important for the proper functioning of the nucleus and its contents. Microtubules are a type of cytoskeleton filament that plays a key role in many cellular processes. They are involved in the movement of organelles and other structures within the cell, as well as in the division of the cell. During cell division, microtubules form the spindle fibers that attach to the chromosomes and help to pull them apart. Movement of chromosomes is a crucial part of cell division, and the process requires a complex interaction of different cellular components. The cytoskeleton plays a key role in this process, and microtubules are an essential component of the cytoskeleton that are involved in the separation of chromosomes during cell division. Microtubules are long, thin, tube-like structures that are made up of protein subunits. They are involved in many different cellular processes, including cell division, cell movement, and intracellular transport. During cell division, microtubules form the spindle fibers that attach to the chromosomes and help to pull them apart.The movement of chromosomes during cell division is a complex process that requires the coordinated action of many different components. Microtubules are involved in this process because they attach to the chromosomes and pull them towards the poles of the cell. This movement is driven by the shortening of the microtubules, which causes them to exert a pulling force on the chromosomes.The formation of a cleavage furrow is a process that occurs during cytokinesis, which is the final stage of cell division. During cytokinesis, the cell membrane pinches inwards and eventually divides the cell into two separate cells. The formation of the cleavage furrow is not directly involved in the movement of chromosomes during anaphase. Therefore, the correct answer to this question is (d) shortening of microtubules.

D) increased tissue PO2

How oxygen is being transported?

About 97% of the oxygen used during breathing is delivered by red blood cells in the blood, while the remaining 3% dissolves in plasma. The pigment hemoglobin, which is found in RBCs, is what gives blood its red color. According to the partial pressures of oxygen, carbon dioxide, H+ concentration, and temperature, oxygen attaches to hemoglobin to create oxyhemoglobin. Up to 4 oxygen molecules can be carried by a single hemoglobin molecule. The optimum circumstances for the synthesis of oxyhemoglobin include low temperature, high H+ concentration, and oxygen partial pressure. In the alveoli, these criteria are satisfied. But in the tissues, the circumstances are different, and as a result, oxygen is separated from oxyhemoglobin.

During the prelarval stages of development, a sea star embryo obtains its nutrition from the yolk that is present within the egg. The yolk serves as a source of nutrients for the developing embryo.

As the embryo develops, it utilizes the stored energy and nutrients from the yolk to support its growth and development.

Sea stars, like many other marine organisms, undergo external fertilization, where the eggs and sperm are released into the water. After fertilization, the zygote develops into an embryo within the protective egg capsule.

The yolk, which is rich in proteins, lipids, and carbohydrates, is present within the egg and provides nourishment to the developing embryo.

As the prelarval stages progress, the embryo undergoes cell division and differentiation, eventually developing into a free-swimming larva. At this stage, the larva will start to feed on external food sources, such as plankton or other microscopic organisms, to sustain its growth and development.

But during the early prelarval stages, the yolk serves as the primary source of nutrition for the sea star embryo.

To answer your question, there are a few positions and projections that can effectively demonstrate a hiatal hernia. A hiatal hernia occurs when the upper part of the stomach protrudes through the diaphragm into the chest cavity. One of the most commonly used projections is the upright position, where the patient is standing and the x-ray beam is directed horizontally.

In this position, the herniated stomach can be seen as a bulge above the diaphragm.
Another projection that can be used is the Trendelenburg position, where the patient is lying on their back with their feet elevated higher than their head. This position allows gravity to pull the herniated stomach back into its normal position, making it easier to detect the hernia.
In addition to these positions, a barium swallow test can also be used to diagnose hiatal hernias. This test involves drinking a barium solution, which highlights the internal structures of the digestive system on x-rays. The patient is then imaged in various positions to help identify any abnormalities, including hiatal hernias.
In conclusion, the upright and Trendelenburg positions, as well as the barium swallow test, can all be effective in demonstrating hiatal hernias. It is important to consult with a healthcare provider to determine the best course of action for diagnosing and treating a hiatal hernia.

The sympathetic division stimulates am increase in heart rate while the parasympathetic division stimulates a decrease in heart rate.

During sex, the parasympathetic division stimulates arousal while the sympathetic division stimulates orgasm.

The parasympathetic division constricts the pupils while the sympathetic division dilates the pupils.

Antagonistic:

Cooperative:

Answer: Antagonistic: The sympathetic division stimulates am increase in heart rate while the parasympathetic division stimulates a decrease in heart rate; The parasympathetic division constricts the pupils while the sympathetic division dilates the pupils.

Cooperative: The sympathetic division stimulates mucus production by salivary glands while the parasympathetic division stimulates enzyme secretion.; During sex, the parasympathetic division stimulates arousal while the sympathetic division stimulates orgasm.

Explanation: The peripheral nervous system is divided in Somatic Nervous System (SNS) and Autonomic Nervous System (ANS). The first is responsible for sensory input and voluntary motion.

Autonomic Nervous System is divided into Sympathetic and Parasympathetic divisions and is controls the fight-or-flight and rest-and-digest situations. Usually, an organ with sympathetic and parasympathetic innervations have antagonic function, such as the heart rate -  one system causes the heart rate to increase while the other stimulates the rate to decrease. However there are cases in which the combination of the 2 systems cause an increase of stimulation, producing similar effects.

Analysing each category above, it is deductable that when the sympathetic stimulates mucus production and parasympathetic, enzyme secretion and when the parasympathetic stimulates arousal and sympathetic, orgasm, in both cases, they have cooperative innervation.

On the other hand, when sympathetic stimulates increase in heart rate and parasympathetic, decrease in the rate, as stated before, and one stimulates constriction of the pupils and the other, dilation of the them, those are examples of having antagonic innervation.

In the past, until the last 25 years or so, accounting principles have required valuation based primarily on historical cost.

Historical cost is the original cost incurred by a company to acquire an asset or service, and it is the value at which an asset is recorded in the financial statements. This method of valuation has been used in accounting because it is objective, reliable, and verifiable. Historical cost is also considered to be conservative, as it does not allow for potential gains in the value of assets over time.

However, in recent years, there has been a shift towards using fair value accounting principles. Fair value is the estimated value of an asset or liability based on current market conditions and future expectations. This method of valuation is considered to be more relevant and useful for financial reporting as it provides more current and accurate information about the value of assets and liabilities.

The use of fair value accounting has been particularly relevant in the wake of financial crises, where historical cost accounting principles were criticized for failing to reflect the true value of assets and liabilities. The shift towards fair value accounting has not been without controversy, as it can be subjective and open to manipulation. Nevertheless, fair value accounting has become increasingly important in financial reporting, and it is likely to continue to play a significant role in accounting principles in the future.

The science concept that individuals with the most selected traits surviving and reproducing in a population is a description of evolution by natural selection.

In this process, organisms with certain advantageous traits have a higher chance of surviving and reproducing, passing these traits on to their offspring. Over time, these advantageous traits become more common in the population, leading to evolutionary changes. Natural selection was first proposed by Charles Darwin and Alfred Russel Wallace in the 19th century, this concept is based on three main principles: variation, inheritance, and differential survival and reproduction.

Variation refers to the differences in traits among individuals within a population. Inheritance indicates that offspring inherit traits from their parents. Differential survival and reproduction mean that individuals with advantageous traits are more likely to survive and reproduce, thereby passing these traits to the next generation. Through natural selection, populations can adapt to their environment and better cope with challenges such as predation, competition, and disease.

Hereditary information is stored in the DNA molecule in the form of three-letter 'words,' each of which designates a specific amino acid. The scientific term for a DNA "word" is a "codon."

A codon is a sequence of three nucleotides (specifically, adenine (A), cytosine (C), guanine (G), and thymine (T)) that codes for a specific amino acid. There are 64 possible combinations of these nucleotides (\(4^3\)), and each codon corresponds to either an amino acid or a stop signal in the genetic code.

During protein synthesis, the DNA molecule is transcribed into messenger RNA (mRNA), which carries the genetic information from the nucleus to the ribosomes in the cytoplasm. The codons on the mRNA are then read by the ribosomes, and each codon is translated into the corresponding amino acid, ultimately leading to the synthesis of a specific protein.

The sequence of codons along the DNA molecule determines the order of amino acids in a protein, thus encoding the genetic information necessary for the synthesis of proteins and the functioning of cells.
