Explanation:

Osmosis is defined as the movement of water from a LOW concentration of solute to a HIGH concentration of solute.

Isotonic means that both the solution (environment of the cell) and the inside of the cell have equal concentrations. Now, it is important to know that even though they may have similar concentrations, there may be different solutes inside or outside of the cell.

Hypertonic is when one solution (either the inside of the cell or the outside) has a higher concentration of a certain solute

Hypotonic is the solution that has the less concentration of a certain solute.

If the inside of the cell has more solute than the outside, then the water will move inside the cell, make it bigger, and eventually make it burst.

If the outside of the cell has a higher concentration of a solute, the water inside the cell will move out of the cell and go to the environment. This will cause the cell to shrink in size.

If both the outside and inside of the cell have the same solutes at the same concentration, then the two are said to be isotonic, and the cell will keep its normal shape.

In the traditional champagne method, also known as méthode champenoise, the process that removes dead yeast cells is called riddling or remuage. After the wine undergoes its secondary fermentation in the bottle, the yeast cells die and form a sediment in the bottle.

To remove this sediment, the bottles are placed on special racks called pupitres at a 45-degree angle, and the bottles are rotated slightly every day to encourage the dead yeast cells to settle in the neck of the bottle. This process can take several weeks or even months, depending on the producer's preference.

Once the dead yeast cells have settled in the neck of the bottle, the next step is called disgorging. The neck of the bottle is frozen to form a plug of ice containing the sediment. The bottle is then quickly opened, and the pressure from the carbon dioxide in the wine forces the plug of ice out, along with the dead yeast cells. The wine is then topped up with a mixture of wine and sugar, called the dosage, to replace the lost volume and balance the wine's acidity.

Overall, riddling and disgorging are crucial steps in the traditional champagne method, as they remove the dead yeast cells and ensure a clear, bright wine that is ready for consumption.

P. acne, or Propionibacterium acnes, is a type of bacteria that commonly colonizes the human skin. Specifically, P. acne tends to reside within the sebaceous glands and hair follicles on the face, neck, chest, and back.

This bacterium is known to play a role in the development of acne, as it feeds on sebum (oil) produced by the skin and can cause inflammation and infection in the hair follicle. While P. acne is a normal resident of the skin microbiome, overgrowth and imbalance can lead to skin issues. In particular, P. acnes is known to colonize within hair follicles and sebaceous glands in the skin. It can also be found in lower numbers in other areas of the skin, such as the armpits and groin.

While P. acnes is a normal part of the human skin microbiome and is generally harmless, it can sometimes contribute to the development of acne. When there is an excess of sebum production or other factors that promote bacterial growth, P. acnes can multiply and cause inflammation, leading to the formation of pimples, blackheads, and other types of acne lesions.

Animals experience an oxidative breakdown of amino acids under three different metabolic conditions: 1. Some amino acids released from protein breakdown that are not required for new protein synthesis go through oxidative degradation during the normal production and destruction of cellular proteins (protein turnover).

Without going through oxidation, some amino acids can be deaminated to release NH3. (a) Amino acid dehydrases: Serine, threonine, and homoserine are the hydroxy amino acids. They go via non-oxidative deamination, which PLP-dependent dehydrases catalyze (dehydratases).In oxidative deamination, amino groups are taken off of amino acids, producing matching keto acids and ammonia in the process. As a result, amino acids are in a sense "wasted" when they are not employed to create protein or other nitrogen-containing molecules.

Explanation:

To make a DNA helix, two DNA strands are required. They are connected by the nitrogenous bases on each strand. Each type of nitrogenous base is complementary to another type: cytosine (pyrimidine) pairs with guanine (purine) and thymine (pyrimidine) pairs with adenine (purine). This means they only bond with their pair.

For every cytosine, there must be a guanine bonded to it. So, if 15% of the strand is cytosine, another 15% must be guanine.

Since,

15% + 15% = 30% and 100% - 30% = 70% ,

30% of the DNA strand consists of the cytosine-guanine pair and 70% of the DNA strand consists of the adenine-thymine pair.

Since,

70% / 2 = 35% ,

70% is made up of equal parts adenine and thymine, 35% of the DNA strand must contain thymine.

When a person drinks nearly pure water, the extracellular fluids become hypotonic.

In the human body, extracellular fluid is a liquid found outside of the cells. Blood plasma and interstitial fluids are two examples of extracellular fluids. The extracellular fluid serves as a medium for exchanging nutrients, oxygen, and waste products among the cells in the body. Extracellular fluids become hypotonic when a person drinks almost-pure water.

A hypotonic solution is one in which there are fewer solutes outside the cell than inside. As a result of osmosis, water will flow from a region with fewer solutes (hypotonic solution) to a region with more solutes (hypertonic solution). Fluid balance in the human body is maintained through the action of osmosis. The flow of fluids between the intracellular and extracellular compartments is critical to maintaining this balance. When a person drinks nearly pure water, the extracellular fluids become hypotonic. As a result, water moves from cells to extracellular fluids.

Answer:

Extinction is a natural process in evolution that occurs when a species dies out completely. Extinction plays a critical role in evolution because it creates opportunities for new species to emerge and diversify. When a species goes extinct, it leaves behind a gap in the ecosystem, which can be filled by new species that evolve to take advantage of the available resources.

Extinction can occur for a variety of reasons, both natural and human-caused. Some of the causes of extinction include:

1: Habitat loss: When the environment that a species relies on for survival is destroyed or altered, the species may not be able to adapt and may die out.

2: Climate change: As the climate changes, some species may not be able to adapt to the new conditions, leading to their extinction.

3: Overhunting or overfishing: When humans hunt or fish a species at a rate faster than it can reproduce, it can lead to the extinction of that species.

4: Pollution: Pollution can harm or kill species directly, or it can damage their habitat and food sources, making it difficult for them to survive.

5: Natural disasters: Natural disasters such as volcanic eruptions, earthquakes, floods, and wildfires can wipe out entire populations of species.

6: Competition from invasive species: When a new species is introduced to an ecosystem and outcompetes native species for resources, it can lead to the extinction of those native species.

Overall, extinction is a natural part of the process of evolution, and it helps to drive the diversification of life on Earth. However, human activities have significantly accelerated the rate of extinction in recent years, which can have serious consequences for ecosystems and the planet as a whole.

Explanation:

Answer:

Red bricks

Explanation:

Proteins are a class of biomolecules that are involved in controlling all of life's activities. They're made up of long chains of amino acids that are connected by peptide bonds. The sequence and structure of amino acids in a protein determine its role.

R groups, which differ between amino acids, are also important for protein function. They contribute to the formation of protein folds and interact with other amino acids and molecules. Protein folding refers to the process by which a protein attains its unique three-dimensional shape, which is critical for its function. When proteins are subjected to extreme conditions like heat, pH, or harsh chemicals, they undergo denaturation. This can result in the loss of protein structure and function.

Enzymes:Enzymes are proteins that catalyze biological reactions by lowering the activation energy required for a reaction. They're also highly specific and can only catalyze a limited number of reactions. Enzymes are critical to many metabolic processes in cells, such as digestion and energy production.

Nucleic Acids:DNA and RNA are the two types of nucleic acids. DNA is a double-stranded helix that contains genetic information. RNA is a single-stranded molecule that assists in the transfer of genetic information from DNA to proteins.

ATP:Adenosine triphosphate (ATP) is a molecule that stores energy in cells. It's used to power many biological processes, including muscle contractions and protein synthesis. Phosphorylation is the process by which ATP donates a phosphate group to another molecule, increasing its energy content. This makes ATP a great energy source for cells because it can be quickly generated and broken down to release energy as needed.

Hence, Proteins are made up of long chains of amino acids that determine their function.

Answer:

by being facilitated

Explanation:

If something needs to enter the cell and could not go through the phospholipid bilayer, it could be assisted through a process known as facilitated diffusion.

Facilitated diffusion involves the passive movement of molecules that will ordinarily not pass through the phospholipid bilayer of the cell membrane through the help of the channel or carrier proteins.

If the phospholipid bilayer will not allow some molecules to pass through it as a result of a concentration gradient, the channel/carrier proteins form a special passage and the molecule is facilitated by such passage to move across the membrane.

In this question, a worm that lives inside a bear is a PARASITE because it is living inside the bear, which is the host in order to obtain nourishments. Note that, the answer is not option D because the bear is a HOST not a parasite.

Forests are called carbon sinks because they forest biomass store more carbon than they release.

This occurs through the process of photosynthesis, where trees and plants absorb carbon dioxide (CO2) from the atmosphere and convert it into energy and biomass. The carbon is then stored in the form of plant tissues, such as leaves, stems, and roots. This process helps to reduce the amount of CO2 in the atmosphere, thereby playing a significant role in mitigating climate change.

Carbon drains out of forest biomes through various natural processes, such as decomposition and respiration, where it is released back into the atmosphere. However, the overall balance in a healthy forest is such that the carbon stored is greater than the carbon released, making the forest a net carbon sink.

Logging can disrupt this balance, as it removes trees and plant materials, which not only reduces the forest's capacity to absorb and store carbon, but also releases the stored carbon back into the atmosphere. However, sustainable forest management practices can help to maintain the carbon sink function of forests.

Groundwater running below the surface and high amounts of water in forest biomes play a role in the overall carbon cycle, but they are not the primary reasons why forests are considered carbon sinks. The main factor is the ability of trees and plants to absorb and store carbon through photosynthesis.

In summary, forests are called carbon sinks because they store more carbon than they release, primarily through the process of photosynthesis. This makes them essential in combating climate change and maintaining a balanced carbon cycle.
