Nwhat phase of meiosis are tetrads of homologous pairs lined up along the center of the cell and attached to the spindle fibers?
answer
anaphase i
anaphase ii
metaphase i
metaphase ii

Option C, Metaphase I

Explanation:

During the metaphase I of the cell division process, the bivalent chromosomes that are attached to the fully formed meiotic spindle arrange themselves at the metaphase plate.

These chromosomes arrange themselves at equal distance on the metaphase plate and also during this phase the centrioles lies at the opposite poles of the cell. The spindle fibre at one end then attaches to one chromosome of each pair while the  spindle fibre at opposite end  attaches to the homologous chromosome

Hence, option C is correct

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.

that would be called plucking : )

explanation:

''plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". as a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock."
