The correct answer is Social Gerontology; Gerontology is the study of aging, including its psychological, social, and societal effects in addition to its physical manifestations.
Aging is the gradual or progressive alteration of an organism that raises the risk of disease, debility, and death. These aging-related characteristics are referred to as senescence.
A satisfying career in gerontology may allow you to put a variety of abilities to use in enhancing the health of senior citizens. You will use a combination of biological and psychological methods to research aging as a gerontologist.

Asymmetric RNA Splicing The first genes with alternative RNA splicing were discovered in the 1970s.
When multiple combinations of exons are joined to make the mRNA, a procedure called alternative RNA splicing enables diverse protein products to be synthesized from a single gene. The frequency of various splicing alternatives is controlled by the cell as a way to regulate the production of different protein products in different cells or at different stages of development.
Alternative splicing can be haphazard, but more often it is controlled and acts as a mechanism of gene regulation. In eukaryotes, alternative splicing is widely recognized as a frequent process of gene control. One estimate place the proportion of human genes that are expressed as numerous proteins by alternative splicing at 70%.

FILL THE BLANK. 13. If we mentally align the continents to fit Wegener's concept of Pangaea, evidence of Late Paleozoic glacial deposits ________.
If we mentally align the continents to fit Wegener's concept of Pangaea, evidence of Late Paleozoic glacial deposits is much easier to understand than in the current continental configuration.
Explain continental drift theory.
One of the earliest theories among geologists regarding how continents moved over time is known as continental drift. The revolutionary theory of continental drift was supported by fossils of similar organisms found on widely separated continents.
Most people think of the scientist Alfred Wegener when they think of the continental drift theory. Wegener presented his theory that the continents were "drifting" across the planet, occasionally crashing through oceans and into one another, in a study that was published in the early 20th century. This movement was dubbed "continental drift" by him.
Wegener was of the opinion that Pangaea, a vast, unified landmass, formerly included all of the continents of Earth. When describing Pangaea and continental drift, Wegener—an astronomer by training—used geology, biology, and botany. For instance, the extinct reptile Mesosaurus fossils are only discovered in southern Africa and South America. The Atlantic Ocean was too large for the freshwater reptile Mesosaurus, which measured barely one meter long. Mesosaurus's existence suggests a single environment with numerous lakes and rivers.

Individuals from two different species mate, but the resulting embryo dies before birth.
Prezygotic and Postzygotic barriers are reproductive isolation mechanisms, which avoid mating events or prevent viable and fertile mixtures between different species. Pre-zygotic barriers: One bird species prefers open areas, whereas another bird species prefers wooded areas. One frog species mates in the spring, whereas another frog species mates in the summer. Postzygotic barrier: A horse and donkey mate to produce a sterile mule. Individuals from two different species mate, but the resulting embryo dies before birth.

Genetic differences are brought on by genetic drift, which occurs at random in any location at any time and pushes organisms to modify the frequency of their genotypes.
By genetic variants, what do you mean?
It is possible to define genetic variants as the existence of different gene sequences in animals belonging to the same species.The genetic drift in the population size of the northern elephant is caused by hunting. Anyone's specific genotype may benefit from hunting, and when this genotype may interbreed, it results in fewer genetic differences.Genetic differences therefore result from genetic drift, which occurs at random in any location at any time and drives organisms to alter their genotype frequency.Genetic variation is the variance in DNA sequences among members of a population. Germ cells, such as sperm and eggs, as well as somatic (all other) cells, are subject to variation.Variation in genetics refers to a person who exhibits traits that are unique from those seen in others of the same sort. It could also be relevant to the genomic differences between individuals of the same species or between populations of the same species that are found in various regions of the globe. It results through chromosomal crossing-over during gametogenesis, which is a special type of genetic recombination. A mutation, particularly one that permanently alters the chromosomal structure, can also cause genetic diversity. Consequently, a variant or mutant may also be affected by genetic variation. An organism that has developed a characteristic(s) due to mutation is referred to as a mutant.Hence, Genetic differences are brought on by genetic drift, which occurs at random in any location at any time and pushes organisms to modify the frequency of their genotypes.

The kinetochores are located at the center of the centrosome and organize tubulin into spindle fibers.
Why are kinetochores located at the center of centrosome?A duplicated chromosome's centromere, also known as the nucleus, is where kinetochore formation occurs. An inner region and an outer region make up a kinetochore. Chromosome DNA is attached to the inner region. Spindle fibers are connected to the outer region. Additionally, kinetochore function is crucial for the cell's spindle assembly checkpoint. At specific points in the cell cycle, checks are done to make sure that cell division occurs correctly. Making ensuring the spindle fibers are properly affixed to chromosomes at their kinetochores is one of the checks. Each chromosome's two kinetochores should be connected to microtubules by opposing spindle poles. If not, the cell that is dividing risked having the wrong number of chromosomes.The cell cycle process is halted when errors are found until they are fixed. A process known as apoptosis will cause the cell to self-destruct if these mistakes or mutations cannot be fixed.What is a kinetochore?For precise chromosomal segregation, the vertebrate kinetochore, a complex structure, determines the attachments between the chromosomes and the microtubules of the spindle.
