Which scientists was the first to suggest that growth of cancerous cells was a result of abnormal chromosomes?
maks197457 [2]

Answer:

The correct answers are B and C. Walter Sutton and Theodor Boveri were the first to suggest that growth of cancerous cells was a result of abnormal chromosomes.

Explanation:

The chromosomal theory of inheritance is a scientific theory that relates chromosomes with the transmission of inheritable characters. It is also called the chromosomal theory of Sutton and Boveri in honor of the two people who independently developed it in 1902, Theodor Boveri and Walter Sutton. This theory states that the alleles, the Mendelian genetic factors, are on chromosomes.

Theodor Boveri and Walter Sutton independently developed the chromosome theory in 1902, Boveri, studying embryonic development in sea urchin and Sutton in this work on meiosis in grasshopper.

Sutton and Boveri's proposition in 1902 that chromosomes are the factors of Mendelian inheritance was controversial until its demonstration in 1915 by the work of Thomas Hunt Morgan in the Drosophila melanogaster fly.

How does adaptation affect the divercity of a species
Brrunno [24]

Answer:

become better fitted to the environment as a result of natural selection. Adaptations generally occur in order to increase the fitness and thus survival of organisms. By being able to adapt to the changing environment, organisms are better able to survive and reproduce.

Many people are under the impression that species require thousands or even millions of years to adapt. This article by Carl Zimmerman explains how evolution can actually occur in surges, a feature of evolution that proves very useful during periods of climate change. It is important to also note that evolution continues to occur long after climate change has stabilized. Delayed reactions continue to change allele frequencies and compositions of populations.

Phenotypic plasticity and the rate of climate change are important factors in determining if a species will be able to adapt.

The phenotypic plasticity of species of brown trout are heritable. If the rate of climate change is slow enough that organisms at the upper range of tolerance can survive, then there is a chance that the species can adapt over time by inheriting this tolerance.

The rate that a species can adapt is related to how drastic of a temperature change it could survive and adapt to. In the case of T. californicus, the fragmented population means that there is large variation in the species (and thus large potential for adaptation), but lower opportunity for adaptation within the individual populations.

A greater amount of variation is indicative of a population that can more readily adapt, as evidenced by this article showing that S. franciscamus,a species of sea urchin, is more likely to be able to adapt to increased carbon dioxide levels than the mussel species M. trossulus over the next 50 years.

A review published this year reiterated the idea that most organisms, marine or terrestrial, have only limited temperature ranges in which they can live, representing their plasticity. Evolutionary changes to this range are considered long-term. In this review, the focus is on Arctic marine organisms, which have extended their temperature ranges to include very cold temperatures.

An organism at the edge of its thermal tolerance may have more difficulty adapting.
