Answer:
Dissociation of actin subunits occurs.
Explanation:
When we add phalloidin to a solution containing G-actin, the phalloidin binds to actin filaments more tightly as compared to actin monomers which leads to a decrease in the constant rate of dissociation of actin subunits from the ends of the filament. This dissociation stabilizes the actin filaments through the prevention of filament depolymerization. So we can conclude that addition of phalloidin to actin leads to stabilizing of actin filaments.
Significant evolution, in Darwin's opinion, moves much too slowly to be seen in a person's lifetime. Recent biological tests have demonstrated that some populations may develop extremely quickly, with significant changes happening over many generations in the lab.
What role does Darwin's theory of evolution play?
- Charles Darwin, a scientist of the 19th century, investigated the idea of natural selection. Natural selection provides an explanation for how a species' genetic features might evolve through time. This might result in speciation, or the creation of a new, separate species.
- The genesis and adaptations of species entered the scientific canon with Darwin's finding of natural selection. The adaptive characteristics of creatures might now be explained by natural processes, much as the occurrences of the inanimate universe, without the need for an Intelligent Designer.

The Thalamus area of the brain may be involved in the discrimination and cognition of pain
The brain's thalamus is a structure that resembles an egg. It serves as a relay station for all incoming hearing, taste, sight, and touch (but not smell) sensory information from your body to your brain. The relay of various sensory information is carried out by a number of nuclei that make up the thalamus.
The thalamus controls awake, alertness, and sleep. The thalamus is responsible for processing all sensory data from your body, with the exception of smell, before it is transmitted to the cerebral cortex of your brain for interpretation. The thalamus is also involved in learning, memory, consciousness, alertness, and sleep.
