Neurons and mature red blood cells do not divide. Skin cells and stomach cells grow and divide rapidly and regularly.

Neurons are cells of the nervous system that do not have centrioles because the centriole is an important organelle for cell division.

Red blood cells do not have nuclei or other organelles required for DNA and RNA synthesis. So they can't divide.

Skin cells lose dead cells every day. So they divide rapidly and regularly to replace the lost cells to prevent infection.

The cells lining the stomach undergo wear and tear during food absorption, digestion, and waste elimination. So these cells also divide rapidly and regularly to replace the lost cells.

The first method used  is biological restoration in which scientists try to increase the reproduction rate of the corals. The techniques vary depending on the reef.

In the scenario of an overgrowth of algae was affecting the growth of coral reefs in one area. So, scientists focused on controlling the algal growth.  This method is less invasive than transplanting entire reefs into the ocean.

The scientific method is described as an empirical method for acquiring knowledge that has characterized the development of science and  involves careful observation, applying rigorous skepticism about what is observed, given that cognitive assumptions can distort how one interprets the observation.

In another scenario, a group of scientists took samples of corals' genomes to find out whether there are types of corals that are more likely to survive warmer temperatures. This method may allow scientists to plant heat resistant corals in high-risk areas. The drawback is the high cost and the time required for genetic testing.

Explanation:

A polymorphic gene has more than two alleles. The more alleles there are in a population, the more polymorphic the gene is.

In a polymorphic gene, the allelic frequency of the most common allele must be minor of 99%, while the less common allele must have an allelic frequency superior to 0.005%. If any allele does not reach this frequency in the population, it is not considered to be common. In fact, it is considered to be a rare allele.

Cats have evolved certain behaviors that are influenced by their natural instincts and experiences.

When a cat sees milk, it may be attracted to it because it contains nutrients that are important for its survival, and the cat may associate the presence of milk with positive experiences. This can include nursing from its mother as a kitten or catching and consuming prey that contains milk or milk products.

On the other hand, when a cat sees a stick, it may perceive it as a threat or danger, and may associate it with negative experiences, such as being hit or attacked by a predator. This can trigger the cat's natural instinct to flee or hide from potential danger, as a survival mechanism.

Overall, a cat's behavior is influenced by its instincts, past experiences, and environmental cues. It may approach things that it perceives as positive or beneficial, and avoid or flee from things that it perceives as dangerous or threatening.

Tim used a chemical control method known as pesticide application.

Pesticide application involves the use of chemicals to control or eradicate pests, such as insects, fungi, and weeds. In Tim's case, he applied a pesticide to the outer layer of his crop stems to control the non-native fungus that had affected his crops. Pesticides can be applied in various forms, such as sprays, dust, and granules.

The type of pesticide used depends on the target pest and the crop being protected. While chemical control methods such as pesticide application can be effective, they also have potential drawbacks, such as the development of pesticide resistance in the targeted pest populations and the risk of harming non-target organisms and the environment.

Explanation:

One must use hot water because the temperature allows to extract the flavour in a more efficient way.

The process of making iced tea by adding the teabag to hot water first and then cooling it down is a common practice for several reasons:

Extraction of Flavor: Hot water helps to extract the flavor compounds from the tea leaves more efficiently. When tea is steeped in hot water, the heat causes the compounds responsible for flavor and aroma to dissolve into the water more readily, resulting in a stronger and more flavorful brew.

Infusion of Tea Leaves: The hot water allows the tea leaves to fully infuse and release their flavors, oils, and other components into the water. This process contributes to a more robust and well-rounded taste profile.

Dilution and Consistency: When iced tea is made with hot water first, it is usually brewed to be slightly stronger than desired. This is because the ice added later will dilute the brew to the desired strength. By initially brewing the tea with hot water, the dilution caused by adding ice cubes ensures that the final drink is not weak or watery.
