Which example illustrates an adaptation that allows trees to survive in the taiga, a biome known for its cold, snowy winters and warm, rainy summers? •Needles have more surface area than leaves, allowing them to absorb more of the sun's rays for photosynthesis.
•Evergreen trees grow all year, crowding out other trees so they have more room for their extensive root systems.
•Needles need not be replaced every spring, increasing the amount of energy available for the short growing season.
•The shape of leaves allows snow to build up on branches, which acts like an insulating blanket throughout the winter.

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.
