An allele frequency change in a population is a change where evolution has happened.

Evolution is the process by which species change over time through mechanisms such as natural selection, genetic drift, and mutation. An allele frequency change occurs when the frequency of a particular allele (version of a gene) in a population changes. If a new allele appears in a population, or if the frequency of an existing allele increases or decreases, this can have a profound effect on the population and may lead to evolution. An allele frequency change is a key indicator of evolution because it demonstrates that the genetic makeup of a population is changing over time.

Organisms that are most closely related are typically those that share the most recent common ancestor. In terms of domains, the Archaea and Eukarya domains are believed to be more closely related to each other than either is to the Bacteria domain.

Therefore, the pair of organisms that are most closely related would be one from the Archaea domain and one from the Eukarya domain.
The three domains of life are Bacteria, Archaea, and Eukarya. The Archaea and Bacteria domains are both composed of prokaryotic organisms, while the Eukarya domain includes all eukaryotic organisms. Eukaryotes have a distinct nucleus and other membrane-bound organelles, while prokaryotes lack these structures.

According to molecular and genetic evidence, Archaea and Eukarya are more closely related to each other than either is to Bacteria. Archaea and Eukarya share several features that distinguish them from Bacteria, including similarities in DNA replication, transcription, and translation. They also share some membrane lipids and some similarities in their cell walls.
Therefore, if we were to choose one organism from each of these two domains, they would be expected to share more recent common ancestry than either would with a representative organism from the Bacteria domain.

It is TRUE that Cactus plants needed to protect themselves so they grew thorns.

For protection against herbivores, cacti have evolved spines from ordinary leaves. Moreover, they might develop barbed spines to make them more painful and challenging to move, scaring off potential predators. Several cacti have evolved to replace their leaves with spines all over their bodies, which resemble porcupine quills, rather than developing leaves just to be eaten by voracious herbivores.

As they have developed barbs as well, these spines are much harder to get rid of than non-barbed spines. This is best illustrated by the numerous barbed spines on opuntia cactus.

The statement that is true when the substrate concentration is much greater than Km is that the reaction rate is at its maximum and is independent of the substrate concentration.

When an enzyme obeys Michaelis-Menten kinetics, and the substrate concentration is much greater than the Michaelis constant (Km), the enzyme is said to be saturated with substrate.

Now, rather than the presence of a substrate, the pace of the reaction is constrained by the enzyme's rate of turnover.

The turnover rate of the enzyme is also known as the maximum velocity of the reaction (Vmax). At high substrate concentrations, the enzyme reaches its Vmax, and the reaction rate becomes constant because all the enzyme molecules are occupied with the substrate.

Therefore, the statement that is true when the substrate concentration is much greater than Km is that the reaction rate is at its maximum and is independent of the substrate concentration.

In other words, increasing the substrate concentration beyond this point will not increase the reaction rate any further, because the enzyme is already working at its maximum capacity.

This sequence of events represents the process by which sound waves are converted into electrical signals that are sent to the brain for processing and interpretation.

The correct order of the steps involved in how we hear is:

The process begins when sound waves enter the ear and travel through the auditory canal. The eardrum vibrates in response to the sound waves, and this vibration is transmitted through a series of tiny bones in the middle ear called the hammer, anvil, and stirrup. These bones transfer the vibration to the oval window, which is a membrane that separates the middle ear from the inner ear. The pressure waves created by the movement of the oval window cause the basilar membrane in the cochlea to move. The basilar membrane is lined with tiny hair cells that are stimulated by the movement, and these hair cells send electrical signals to the auditory nerve. The auditory nerve carries these signals to the thalamus, which acts as a relay station for sensory information. Finally, the thalamus directs the information to the brain's primary auditory cortex, where the sound is perceived and interpreted.

All turtles that hatch from eggs that are incubated below 28°C are male. Every egg develops into a female over 31°C. The broods will produce both males and females at intermediate temperatures. While most sex chromosomes at the moment of fertilisation define the sex of most snakes and most lizards, the environment after fertilisation determines the sex of most turtles and all species of crocodilians.

Small changes in temperature can result in dramatic changes in the sex ratio in these reptiles, where the temperature of the eggs during a specific stage of development determines sex (Bull 1980). Eggs typically create one sex when incubated at moderate temperatures (22–27°C), but eggs incubated at higher temperatures (over 30°C) typically produce the other sex. The temperature range that allows both males and females to hatch from the same brood of eggs is quite narrow. The sudden temperature-induced change in sex is depicted.All turtles that hatch from eggs that are incubated below 28°C are male. Every egg develops into a female over 31°C.
