The latitude of a particular ecosystem determines the climate zone of the ecosystem. What type of seasonal variation occurs in ecosystems in temperate zones, which are latitudes between 23.5° and 66.5°? Temperate zones experience warm, pleasant weather all year long because the amount of sun they receive is relatively constant all year.

Temperate zones experience extremely hot summers and brief, mild winters because this zone receives direct sun all year.

Temperate zones experience hot summers and cold winters because the sun is lower in the sky in the winter compared to summer.

Temperate zones experience short, mild summers and extremely cold winters because this zone receives less direct sun all year.

Will mark brainliest i only need the ! 1.use ten beads and a centromere of one color to construct the long chromosome. use ten beads and a centromere of a second color to construct the second chromosome in the long pair. make a drawing of the chromosomes in the space below. 2. for the second pair of chromosomes, use only five beads. 3. now model the replication of the chromosomes. make a drawing of your model in the space below. part b: meiosis i during meiosis i, the cell divides into two diploid daughter cells. 4. pair up the chromosomes to form tetrads. use the longer tetrad to model crossing-over. make a drawing of the tetrads in the space below. 5. line up the tetrads across the center of your “cell.” then model what happens to the chromosomes during anaphase i. 6. divide the cell into two daughter cells. use the space below to make a drawing of the result. part c: meiosis ii during meiosis ii, the daughter cells divide again. 7. line up the chromosomes at the center of the first cell, one above the other. separate the chromatids in each chromosome and move them to opposite sides of the cell. 8. repeat step 7 for the second cell. 9. divide each cell into two daughter cells. use the space below to make a drawing of the four haploid cells
