The answer is '<span>triploid cell'. 
</span>

This occurs when two sperm nuclei reach the interior of a female gametophyte, where one sperm will fertilise the egg cell to form a zygote, whereas the other usually fuses with the binucleate central cell, forming a primary endosperm cell, effectively constituting an organism separate from the growing embryo. Approximately 70% of angiosperm species have polyploid endosperm cells which are typically triploid (containing three sets of chromosomes), but can vary widely from diploid(2n) to 15n.

Compare the biomes of New York City and Seattle. Why are their biomes different?
kupik [55]

Answer with Explanation:

New York City is located in the <em>eastern part of the USA.</em> Places in this area have a<em> "temperate deciduous forest</em>" as its biome. This kind of biome constantly changes and thus, it experiences four types of seasons (winter, spring, summer and fall). Precipitation in this biome occurs all throughout the year thus, this supplies the amount of water needed for plants and animals to grow. This also makes the soil fertile which allows the growth of <em>"hardwood trees."</em> In this sense, it becomes easier to build houses, facilities and other buildings, thereby increasing the population in this area.

On the contrary, Seattle is located on the<em> western area of the USA. </em>Places in this area have a <em>"temperate coniferous forest"</em> as its biome. This kind of biome has a moist temperate, thus resulting to evergreen forests even during winter. It has one of the longest dry summers in the world that it is said to have even stood out. However, temperate coniferous forests are known for having<u> warm summer and cool winter</u>. This allows the growth of many kinds of plants<em> (Needleleaf </em>and<em> Broadleaf). </em>
