<span>AntiÂpsychotic drugs generally work by blocking a specific subtype of the dopamine receptor, known as the D2 receptor. This helps to regulate the functioning of brain circuits that control thinking, mood, and perception.</span>
Yes, the different frequencies of evolutionary change could affect allele frequency in a population.
<h3>What are the agents of evolutionary change? </h3>
All populations are usual in a constant state of evolution. This means that all the species are continuously changing their genetic makeup over different generations. These changes can be subtle or they can be spontaneous.
If a population is not evolving, it is said to be in Hardy - Weinberg state. In this state, the allele frequency and the genetic makeup of the population will remain the same across generations.
The agents of evolutionary change defy the Hardy - Weinberg state. These are mutation, gene flow, non-random mating, natural selection and genetic drift.

The effect Colchicine might have on dividing cells is that the duplicated chromosomes might not be able to segregate into daughter nuclei.
Colchicine is an alkaloid that attaches to tubulin and prevents it from polymerization to microtubules. As we know that Microtubules are a component of the cytoskeleton of a cell that aids in molecular mobility inside the cell.
During cell division, chromatin condenses into chromosomes, which are then connected to microtubules. The chromosomes are separated into daughter cells by microtubules.
When these cells are treated with colchicine, tubulin polymerization to microtubules may not occur, and the chromosomes containing daughter nucleic might not be separated.

Answer:
large mammals such as gorillas
Explanation:
The survivorship curves refer to the graphical representation of the proportion of the fraction of survivors or the individuals at a given age.
There are three types of survivorship curves which can be constructed by studying the life history of the organisms.
The type I survivorship curve is the curve which can be formed with the organism which has a high survival rate at the younger and middle age and high death rate at the older age. The type I curve can be characterised by its convex shaped. The type I is showed by the large mammals like gorilla, humans and many others.
Thus, large mammals such as gorillas are the correct answer.
