Synthetic fibers can vary greatly from one another. The main reason they can have such varying characteristics is that they can be of four distinct types.
Synthetic fibers are those that cannot be found in nature, but rather are created by man. They can be of four types:
Nylon RayonPolyesterAcrylicRayon is one of the types of synthetic fibers created by man. One of the weaker fibers, It is commonly referred to as synthetic silk, having many properties similar to those of silk. It is the result of wood pulp being fused with cotton or wool and is commonly used to create beddings and other home decorations, in varying colors.
Nylon shares few, if any, characteristics with rayon. It is a strong and elastic synthetic fiber. In fact, nylon is stronger than steel wire, even though it is created from water, coal and air. Nylon can be found in tents, climbing equipment, toothbrushes, and many more everyday appliances.
Polyester is a stranger form of synthetic fiber. As its name implies, it is formed from the repetition of esters. Polyester is often used for dressing, given its wrinkle-free properties and resistance. However, many kinds of polyesters exist, leading to its use in bottles, wires and more.
Finally, Acrylic is the final kind of synthetic fiber. Acrylic is a fiber which is normally used to replace wool. Acrylic can be seen used in blankets and sweaters. It is also often used to create panels that will imitate glass, which shows exactly how flexible and useful synthetic fibers can be.

which enzyme pairs corresponding nucleotides to a preexisting dna chain in order to synthesize a new strand of dna?
Answer:
✓ DNA polymerase
Explanation:
How does this question represent the law of conservation of energy that energy cannot be created or destroyed? Consider the role of photosynthesis in your answer.
You need to put this into your own words, or else your school system will detect you copied from a source named Brainly.
Anyways, the law of conservation of energy is exactly what it says. Energy cannot be created nor destroyed. All they do is rearrange.
Now, for photosynthesis, it's an interesting thing. Photosynthesis takes the energy from the sun's light to produce sugars/carbohydrates. The sun's energy just got reused. It also uses water, which comes from the soil/ground. This simply, reuses the water. During photosynthesis, it also absorbs the carbon dioxide from the air. The carbon dioxide like everything else listed, got reused.
Meaning, energy does not leave. It endlessly works for different purposes. And as you should know, all of the water on the planet has been here since the dawn of time.
Hopefully this makes sense. Have a nice day!
Most of the reactions by which energy from carbohydrates is released for use by the cell take place within the
A) Mitochondria.
B) Nuclei.
C) Ribosomes.
D) Vacuoles
Most of the reactions by which energy from carbohydrates is released for use by the cell take place within the MITOCHONDRIA. These organelles (mitochondria) are the energy centres of the cell.
Cellular respiration is a series of metabolic reactions by which the cell produces energy in the form of ATP by using the energy stored in the chemical bond of simple carbohydrates and oxygen.
Cellular respiration has three stages: glycolysis, the citric cycle and oxidative phosphorylation.
Glycolysis occurs in the cytoplasm, whereas the citric cycle and oxidative phosphorylation take place in the mitochondria.

How does independent assortment increase genetic variation in Meiosis?
Answer:
Independent assortment produce new combinations of alleles.
Explanation:
In meiosis I, crossing over during prophase and independent assortment during anaphase creates sets of chromosomes with new combinations of alleles. Genetic variation is also introduced by random fertilization of the gametes produced by meiosis. It results in gametes that have unique combinations of chromosomes.
Why does the brain of mammals keep track of the temperature of the skin and the blood?

The brain of mammals keeps track of the temperature of the skin and the blood so that they can regulate the cells and maintain homeostasis in the body relative to the outer environment.
What is the importance of homeostasis in the body?The body's homeostasis should always be maintained in order to keep the cells and organs active and able to perform their functions. Because the brain has different control centers, it keeps track of the skin and blood temperature because the brain can release different hormones depending on the situation. The lipid composition and arrangements of the cells change in the summer and the winter, and all these are possible due to the brain sending signals to cells.
Hence, the brain of mammals keeps track of the temperature of the skin and the blood so that it can regulate the cells and maintain homeostasis in the body relative to the outer environment.

explain a situation where someone could use ph test kits in your neighborhood
Answer:
TO TEST SUPPLY OF WATER QUALITY OF THE LOCALITY Excessively high and low pHs can be detrimental for the use of water. High pH causes a bitter taste, and water pipes.
Alkaline water turns red litmus paper blue. Acidic water turns blue litmus paper crimson. Pure or neutral water won't modify the litmus paper's color.Therefore, it can be used to test the quality of the drinking water.
What is pH?
A quantity that expresses the degree to which a substance or solution is acidic or basic. On a scale that ranges from 0 to 14, pH is measured. A pH value of 7 is considered neutral on this scale, which indicates that the substance in question is neither acidic nor basic. If the pH value is lower than 7, the substance in question is more acidic, and if the pH value is higher than 7, it indicates that the substance in question is more basic.
It is recommended that you consume water that is neither overly acidic nor overly alkaline, as well as water that is both clean and pure. The Environmental Protection Agency of the United States suggests that the pH level of drinking water should fall somewhere in the range of 6.5 to 8.5. The pH reading of the vast majority of ground and surface water should fall somewhere within this range.

What the relationship between a glucose molecule and the products it makes during cellular respiration.
Answer:
During cellular respiration, a glucose molecule is gradually broken down into carbon dioxide and water. Along the way, some ATP is produced directly in the reactions that transform glucose. Much more ATP, however, is produced later in a process called oxidative phosphorylation.
During cellular respiration, glucose makes water, carbon dioxide, ATP, lactic acid, and ethanol. In the absence of oxygen, ethanol and lactic acid are formed from the glucose.
What is glycolysis?
Glycolysis is a process in which glucose breaks down inside a cell. Glucose makes pyruvate as an end product in this process. In the presence of oxygen, glucose breaks down into pyruvate and proceeds to the Krebs cycle. In this process, ATP, water, and carbon dioxide are released.
In the absence of oxygen, glucose is converted into lactic acid and ethanol. This is called fermentation and produces only 2 ATP from glucose. This is called anaerobic respiration.
When oxygen is present from glucose, nearly 36-38 ATP are formed. Pyruvate converts into acetyl CoA, and it enters the Krebs cycle. A complete oxidation of glucose takes place in the presence of oxygen.
Hence, in the presence of oxygen, 36-38 ATP is released from glucose, and in the absence of oxygen, lactic acid and ethanol are produced with 2 ATP.

The cell will shrink as the solvent from low concentration solute will move towards the high concentration solute.
What is osmosis ?Osmosis is the spontaneous net movement or diffusion of solvent molecules through a selectively permeable membrane from a region of high water potential to a region of low water potential, in the direction that tends to equalize the solute concentrations on the two sides.
Since the solute concentration in the muscle cell is just 2%, and the muscle cell is dipped in a solution that contains 5% solute, the solvent will flow from the muscle cell into the solution. This will result in the muscle cell becoming smaller until the concentration of solutes on both sides is equivalent.
