Distillation can remove a lot of contaminants from water except
salt
VOCs
alcohol
particulates
Answers
Distillation is an effective water purification method that can remove various contaminants through the process of vaporization and condensation. However, it has limitations in removing certain substances, and one of those substances is salt.
Distillation is primarily used to remove dissolved solids and impurities from water by boiling it and then condensing the resulting steam. This process effectively eliminates most contaminants, including volatile organic compounds (VOCs), alcohol, and particulates.
VOCs are organic chemicals that can easily vaporize and contaminate water sources, but they are effectively removed during distillation. Similarly, alcohol, which has a lower boiling point than water, can also be separated and removed through the distillation process.
Particulates, such as sediment and suspended solids, are left behind during distillation, as they do not vaporize and are not carried with the steam.
However, distillation is not effective in removing salt from water. Salt, or sodium chloride, has a much higher boiling point than water, so it does not vaporize during the distillation process.
As a result, the distilled water obtained through this method may still contain salt, unless additional purification techniques like reverse osmosis or ion exchange are employed.
In conclusion, while distillation is an efficient method for purifying water and removing a wide range of contaminants such as VOCs, alcohol, and particulates, it is not capable of removing salt from water.

An increase in tonicity of the bacterium's environment
Fission of the bacterium into two daughter cells
Growth of the bacterium's flagella from the basal body
Answers
Answer:
B. An increase in tonicity of the bacterium's environment
Explanation:
An increase in the tonicity of the bacterium's environment will decrease the diffusion rate.
Tonicity affects the osmotic regulation of the cell and as tonicity increases the cell becomes hypertonic and water moves out of the cell.
So, an increase in tonicity makes it difficult to get water in the cell and the cell will become dehydrated due to lack of water.
Hence, the correct option is "B."

Plant bodies can respond to changes in their environmental conditions. How does a plant regulate water in its body?
A by growing toward a light source
B by photosynthesizing more energy
C through the opening and closing of stomata
D through wilting and dropping leaves
Answers
The correct option is C; Through the opening and closing of stomata , located on the leaves' surfaces, are involved in regulating gas interchange and water release. Plants regulate water by opening and closing stomata.
Stomata are small pores placed in the leafs' surfaces, whose opening is regulated by two guard cells surrounding them.
These pores are involved in gas interchange -letting CO₂ get into the plant, and O₂ leave it- and the transpiration process -expelling water through transpiration-.
Guard cells can expand or contract according to the plants' needs, causing the stomata to open or close.
Stomata opening and closure depend on water and CO₂ concentration inside the plant.
· If the plant is dehydrated, stomata close. If it is not dehydrated, it opens.
· If CO₂ levels are too low, stomata open to gain it.
So, stomata affect photosynthesis by controlling gas interchange -CO₂ and O₂- and water release -transpiration-.
Water balance:
· Stomata also regulate water vapor flow through transpiration.
· By limiting its exit, stomata allow more water molecules to be available for light reaction processes when the plant is dehydrated.
According to this information, plants regulate water in their bodies by opening and closing stomata.

QUESTION: If there was no atmosphere around Earth, how would that impact your life in the planet?
Answers
Have you ever wondered what would happen if Earth lost its atmosphere? It's believed that the planet is slowly losing its atmosphere, bit by bit, as it bleeds off into space. But what if Earth instantly lost its atmosphere, all at once? Just how bad would it be? Would people die? Would everything die? Could the planet recover?
What Would Happen?
Here's a breakdown of what could be expected:
It would be silent. Sound requires a medium to transmit waves. You could feel vibrations from the ground, but you wouldn't hear anything.
Birds and planes would fall from the sky. Although we can't see air (except clouds), it has mass that supports flying objects.
The sky would turn black. It's blue because of the atmosphere. You know those pictures taken from the Moon? The Earth's sky would look like that.
All unprotected plant and animal life on the Earth's surface would die. We can't survive long in a vacuum, which is what we'd have if the atmosphere suddenly vanished. It would be much like being "spaced' or shot out of an airlock, except the initial temperature would be higher. Eardrums would pop. Saliva would boil. But you wouldn't die instantly. If you held your breath, your lungs would pop, which would be the quickest (albeit most painful) death. If you exhaled, you'd pass out in about 15 seconds and die in around three minutes. Even if you were handed an oxygen mask, you wouldn't be able to breathe. This is because your diaphragm uses the pressure difference between the air inside your lungs and outside your body to inhale.
Let's say you have a pressure suit and air. You'd live, but you'd get a massive sunburn on exposed skin because the Earth's atmosphere is what filters solar radiation. It's hard to say how much trouble you'd be in from this effect on the dark side of the planet, but being in direct sunlight would be severe.
The rivers, lakes, and oceans would boil. Boiling occurs whenever vapor pressure of a liquid exceeds external pressure. In a vacuum, water readily boils, even if the temperature is warm. You can test this yourself.
Although water would boil, the water vapor would not fully replenish the atmospheric pressure. An equilibrium point would be reached where there would be enough water vapor to prevent the oceans from boiling off. The remaining water would freeze.
Eventually (long after surface life had died), solar radiation would break atmospheric water into oxygen, which would react with carbon on the Earth to form carbon dioxide. The air would still be too thin to breathe.
The lack of atmosphere would chill the Earth's surface. We're not talking absolute zero cold, but the temperature would drop below freezing. Water vapor from the oceans would act as a greenhouse gas, raising the temperature. Unfortunately, the increased temperature would allow more water to transition from the sea into the air, likely leading to a runaway greenhouse effect and making the planet more like Venus than Mars.
Explanation:
Organisms that need air to breathe would die. Plants and land animals would die. Fish would die. Most aquatic organisms would die. However, some bacteria could survive, so losing the atmosphere wouldn't kill all life on Earth. Chemosynthetic bacteria wouldn't even notice the loss of atmosphere.
Volcanoes and geothermal vents would continue to pump out carbon dioxide and other gases to add to the water. The most significant difference between the original and new atmosphere would be the much lower abundance of nitrogen. Earth could replenish some nitrogen from meteor strikes, but most of it would be lost forever.
Could Humans Survive?
There are two ways human beings could survive losing the atmosphere:
Build radiation-shielded domes on the Earth's surface. The domes would need a pressurized atmosphere and would need to support plant life. We would need time to build biodomes, but the result would not be much different from trying to survive on another planet. Water would remain, so there would be a source of oxygen.
Build a dome under the sea. The water could provide pressure and filter out some solar radiation. We wouldn't want to filter out all radiation because we'd probably want to grow plants (though maybe it would be possible to learn some tasty ways to prepare bacteria as food).

Which feature of the model represents stored chemical energy
Answers
The sugar molecule represents the most stored chemical energy. Thus, the correct answer is Option B.
Sugar (glucose, C₆H₁₂O₆) is a biological molecule that stores energy in its chemical bonds, not the molecule that initiates the process of cellular respiration During cellular respiration, glucose is broken down in a series of chemical reactions to produce energy ATP (adenosine triphosphate).
The process of cellular respiration begins at the stage of glycolysis, where glucose in the cytoplasm of the cell is partially broken down into pyruvate molecules and then the pyruvate molecules are broken down again in the presence or production of oxygen (aerobic respiration). fermentation in the absence of oxygen depending on whether oxygen is present
During aerobic respiration, pyruvate enters mitochondria and undergoes the citric acid cycle (also known as the Krebs cycle) and the electron transport chain These processes release energy from glucose chemical bonds to produce more ATP.
Therefore, sugar (glucose), although it stores energy in its chemical bonds, is not the molecule that initiates cellular respiration. Instead, during cell respiration, glucose is broken down and energy is released in the form of ATP.

Answers
The symptoms of stress are associated with both the Alarm Reaction and the Stage of Resistance.
How are the symptoms of stress associated with different stages?The body's response to stress involves multiple stages, including the Alarm Reaction and the Stage of Resistance. During the Alarm Reaction, the body releases stress hormones such as adrenaline and cortisol, leading to various physiological changes.
Symptoms such as increased heart rate, sweating, and heightened alertness are associated with the immediate response to stress. As the stress continues, the body enters the Stage of Resistance, where it attempts to adapt and cope with the ongoing stressor.
This stage is characterized by the activation of various hormonal and physiological mechanisms, including increased levels of aldosterone, antidiuretic hormone (ADH), and angiotensin. These changes help regulate blood pressure, fluid balance, and electrolyte levels.
Symptoms such as increased water retention and elevated blood pressure can be observed during this stage.
In summary, the symptoms of stress are influenced by both the immediate response (Alarm Reaction) and the long-term adaptation (Stage of Resistance) to stressors.

The exchange of oxygen and carbon dioxide between the air in the alveoli and blood in the lungs is called pulmonary gas exchange.
The pulmonary gas exchange process occurs in the lungs during the process of respiration. Alveoli are the tiny sacs in which the oxygen from the inhaled air diffuses across the thin walls into the bloodstream then it binds to haemoglobin in red blood cells. Simultaneously, carbon dioxide diffuses out from the bloodstream into the alveoli and exhaled from the body.
The necessary oxygenation of the body's tissues is ensured by pulmonary gas exchange, which also ensures a new supply of oxygen in the blood and the elimination of carbon dioxide. It supports cellular respiration, which is how cells use oxygen to make energy and is an important step in the whole respiratory process.

It is a part of external respiration. In other words, it is the process of gas exchange that occurs in the lungs between the air and blood.Long answerThe exchange of oxygen and carbon dioxide between the air in the alveoli and blood in the lungs is called pulmonary gas exchange. Pulmonary gas exchange is the process by which oxygen and carbon dioxide are exchanged between the lungs and the environment. Pulmonary gas exchange occurs between alveolar air and pulmonary capillary blood, resulting in the transfer of oxygen from the air to the blood and the transfer of carbon dioxide from the blood to the air. It is a part of external respiration.In order to achieve pulmonary gas exchange, a number of factors must be in place.
This means that the alveoli, which are small air sacs in the lungs, must be able to exchange gases effectively. The alveoli are surrounded by capillaries, which are small blood vessels that transport blood from the heart to the lungs and back again. The capillaries in the lungs are responsible for carrying oxygen-rich blood to the body's tissues, and they also carry carbon dioxide back to the lungs for removal from the body.Another important factor in pulmonary gas exchange is the presence of a concentration gradient. This means that there must be a difference in the concentration of oxygen and carbon dioxide between the alveolar air and the pulmonary capillary blood. This gradient allows for the efficient transfer of gases between the air and the blood.In summary, pulmonary gas exchange is the process of gas exchange that occurs in the lungs between the air and blood. It is a vital process that allows for the delivery of oxygen to the body's tissues and the removal of carbon dioxide from the body.

explain electron flow through each photosystem, what the energy in the electrons is used to do, and how each photosystem replaces its lost electrons. be sure to clearly identify the key product of each photosystem. in addition, explain why oxygen is produced as a waste product of this process.
Answers
Photosystems are responsible for capturing light energy and converting it into chemical energy in the form of ATP and NADPH. The process of electron flow through each photosystem involves a series of complex reactions and transfers of electrons that ultimately lead to the production of ATP and NADPH.
The first photosystem, Photosystem II (PSII), absorbs light energy and uses it to transfer electrons from water molecules to a molecule called plastoquinone. This process generates ATP through a process called photophosphorylation. The key product of PSII is oxygen, which is produced as a waste product during the process of electron transfer.
The second photosystem, Photosystem I (PSI), absorbs light energy and uses it to transfer electrons from a molecule called plastocyanin to another molecule called ferredoxin. This process generates NADPH, which is used as an energy source for various cellular processes. The key product of PSI is NADPH.
In order to replace the lost electrons in each photosystem, water is split into oxygen and hydrogen ions. The oxygen is released as a waste product, while the hydrogen ions are used to replace the lost electrons in PSII.
Overall, the energy in the electrons is used to power the processes of ATP and NADPH synthesis, which are essential for cellular metabolism and growth. The production of oxygen as a waste product is a byproduct of the electron transfer process and is critical for maintaining the balance of atmospheric gases.
