Some damaged fruits release a chemical called ethylene, which attracts fruit flies. as the fruit flies eat the fruit, they cause more damage, resulting in more ethylene release, attracting more fruit flies and so on. this is an example of a positive feedback loop.
Ethylene gas has a major role in the ripening and ripening process of climacteric fruits such as apples, bananas and mangoes. The presence of ethylene makes the previously green-skinned fruit turn yellow, release its aroma, and soften the flesh until it becomes overripe and spoiled. Ethylene will attract fruit flies to come closer.
In a positive feedback loop, a change in a system triggers a chain of events that further amplifies the original change. In this example, the release of ethylene attracts fruit flies which causes more damage, resulting in more ethylene release, which attracts even more fruit flies and so on.

Hair colors
1. Is the mutation helpful, harmful or
neutral for humans? How do you know?
What are some reasons you can
hypothesize for this?
Hair colors is a mutation that is neutral for humans.
Some persons have coloured hair through viable errors resulting from mutations in the genetic code.
What are mutations?Any error or mutation that keeps the affected cell alive would be considered a viable one. This is because there are mutations in which key features or processes essential to life have to be altered.
The cells that undergo these alterations would not be able to sustain life. The mutation that results in coloured hair is one that doesn't disrupt a crucial procedure; it affects the gene that makes melanin, the pigment that gives hair its color.
As a result, we can say with certainty that some people have coloured hair as a result of viable errors or mutations that do not affect life-supporting systems.

True/False: viruses, liposomes, and direct injections are techniques used to introduce a normal into an individual who has a certain disease or genetic condition.
The given statement "Viruses, liposomes, and direct injections are techniques used to introduce normal genes into an individual who has a certain disease or genetic condition." is True. This process is known as gene therapy.
Gene therapy is a medical technique that is used to correct or replace faulty genes in order to treat or prevent disease. In some cases, a normal gene may be introduced into an individual's body to replace a missing or non-functional gene. In other cases, a gene may be corrected or repaired to prevent the development of a disease.
Viruses are one of the most common vehicles used to deliver genes to the body's cells. Specifically, scientists use viruses that have been altered so that they are no longer harmful to introduce normal genes into the body. These viruses are often used because they are very efficient at entering cells and delivering genetic material.
Liposomes are another technique used to introduce normal genes into an individual's body. Liposomes are tiny spheres made up of a fatty substance that can encase genetic material. These spheres are then introduced into the body, where they can fuse with cell membranes and deliver the genetic material.
Direct injection is also a technique that is used in gene therapy. In this technique, a normal gene is injected directly into the tissue where it is needed. For example, if a patient has a genetic disease that affects their liver, a normal gene may be injected directly into the liver tissue.
Overall, gene therapy is a promising field of medicine that has the potential to treat or even cure a wide range of genetic diseases. However, there is still much research to be done in order to fully understand the safety and efficacy of these techniques.

Use the following information to answer the questions below.
Succinate dehydrogenase catalyzes the conversion of succinate to fumarate. The reaction is inhibited by malonic acid, which resembles succinate but cannot be acted upon by succinate dehydrogenase. Increasing the ratio of succinate to malonic acid reduces the inhibitory effect of malonic acid.
Based on this information, which of the following is correct?
Question 26 options:
Succinate is the substrate, and fumarate is the product.
Fumarate is the product, and malonic acid is a noncompetitive inhibitor.
Succinate dehydrogenase is the enzyme, and fumarate is the substrate.
Succinate dehydrogenase is the enzyme, and malonic acid is the substrate.
Succinate is the substrate, and fumarate is the product.
Succinate dehydrogenase is an enzyme that catalyzes the conversion of succinate to fumarate in the citric acid cycle. Inhibition of this enzyme by malonic acid suggests that malonic acid is a competitive inhibitor that competes with succinate for the active site of succinate dehydrogenase but cannot be acted upon by the enzyme.
Increasing the ratio of succinate to malonic acid reduces the inhibitory effect of malonic acid because the more substrate (succinate) there is, the more likely it is to bind to the active site of the enzyme instead of the inhibitor (malonic acid).
Therefore, succinate is the substrate that is acted upon by the enzyme, and fumarate is the product that is produced by the catalytic activity of succinate dehydrogenase. Malonic acid, on the other hand, is a competitive inhibitor that prevents the enzyme from binding to its natural substrate, succinate.

the reason ions such as na , k , and ca2 diffuse accross plasma membranes more readilt than would be expected across a lipid membrane is
The reason ions such as Na⁺, K⁺, and Ca²⁺ diffuse across plasma membranes more readily than would be expected across a lipid membrane is due to proteins embedded within the membrane. These proteins form channels and pores in the membrane, allowing the ions to pass through much more easily than they would otherwise. This is referred to as facilitated diffusion.
The proteins within the membrane can be selective, allowing certain ions to pass while blocking others. For example, Na+ channels are highly permeable to Na⁺ but are impermeable to other ions such as K⁺ or Ca²⁺. This allows Na⁺ to pass more easily through the membrane than other ions and therefore is more readily diffused. The embedded proteins in the membrane are what make facilitated diffusion possible, allowing ions such as Na⁺, K⁺, and Ca²⁺ to diffuse across the membrane more readily than would be expected across a lipid membrane.
