The
general trend shown is that the amount of crop that a farmer can
harvest per year keeps increasing by adopting the genetically
modified crops in the U.S. and it keeps growing steadily. If it keeps
up the future of GM crops use will depend on the ability of the
farmers to adopt best management practices and the acceptance of the
consumer for products from GM sources.

A forest fire causes a dramatic, sudden reductions in population size. It affects all population in this way, regardless of whether they are big or small.
Hola!
Geographic Isolation prevents the cross breeding between the populations that have been separated by the isolation.
Without the separation the two growing population would be brought closer together and members of the two populations will cross breed.
♦ Example:
There are two populations of squirrels on either side of the grand canyon.
↑↑↑
These populations are considered two different species.
We can conclude that these 2 populations were once one population.
Isolation allowed the two populations to move apart and speciation occurred.

Answer:
Option a is the one, that is true.
Sister chromatids separate in anaphase of mitosis and anaphase Il of meiosis
Explanation:
After the interphase in the cell division cycle, the mitosis process begins, which is composed of 4 phases, prophase, metaphase, anaphase and telophase. The prophase occurs when the chromatin is condensed and the mitotic spindle is formed, the metaphase the chromosomes align along the cell equator, in the anaphase the separation of the sister chromatids occurs and in the telophase finally the heterochromatin is converted into euchromatin and the envelope is formed nuclear cell.
Meiosis, which is the cell division of germ cells, also has the same phases but they occur on two occasions: prophase I, metaphase I, anaphase I and telophase I for meiosis I and for meiosis II, prophase II, metaphase II, anaphase II and telophase II. In the anaphase I the homologous chromosomes are separated, they are condensed in the prophase II while in anaphase II the chromatids are separated.
The answer to the question of what relationship is classified as host-parasite. A parasitic relationship is one in which one organism, the parasite, lives off of another organism, the host, harming it and possibly causing death. A few examples of parasites are tapeworms, fleas, and barnacles. The parasite lives on or in the body of the host.
