Answer:
The sister chromatids are identical to one another and are attached to each other by proteins called cohesins. They are formed.
Explanation:
Meiosis produces cells (germ cells or gametes) with only half the DNA, or chromosomes, as normal cells (somatic cells). This is called haploid or referred to as "n" number of chromosomes. Normal body cells have doubke that, called "2n," or diploid. For humans our n = 23, so germ cells (haploid) have only 23 chromosomes, while somatic (normal body) cells have "2n" or 46 chromosomes. It is important to only carry half the number of chromosomes or DNA (n), because it is going to combine with another half (n) when sperm meets egg during fertilization. This n + n = 2n restores the diploid number of chromosomes (DNA) in a zygote, the first cell of a future embryo, fetus, and new human being.
A. Most people thought that trillium was not getting enough sunlight in the forest.
Explanation – Scientists used to believe that the population of trillium decreased because there were not enough sunlight to reach these plants. Later, it was found that deer used to eat the flowers of trillium plant that led to the decrease of its population.
The seed of the trillium plant is very nutritious and hence consumed by the deer. Because of this, trilliums were found to be unlikely to recolonize local areas on their own.

Organizations must constantly analyze their external environments and their competition for innovation that may reduce or eliminate a competitive advantage. Innovation enables organizations to remain relevant in the competitive market, it also plays an important role in economic growth.
