Read each of the sentences that describe a phase of meiosis. Place each sentence into the correct box.
Lady bird [3.3K]

Answer:

Prophase1-crossing over may occur between the non-sister chromatids

Metaphase1- Homologous chromosomes line up at the center of the cell

Anaphase and telophase 1- homologous pairs separate and move towards opposite ends of the cell, Nuclear membrane forms and cytokinesis follows.

Meiosis 2- haploid number of duplicated chromosome line up…

Sister chromatids separate and become daughter…

Four haploid daughter cells are formed….

Explanation:

Meiosis I

P-I: Chromosomes condense, nuclear membrane dissolves, homologous chromosomes form bivalents, crossing over occurs

M-I: Spindle fibres from opposing centrosomes connect to bivalents (at centromeres) and align them along the middle of the cell

A-I: Spindle fibres contract and split the bivalent, homologous chromosomes move to opposite poles of the cell

T-I: Chromosomes decondense, nuclear membrane may reform, cell divides (cytokinesis) to form two haploid daughter cells

Meiosis II

The second division separates sister chromatids (these chromatids may not be identical due to crossing over in prophase I)

P-II: Chromosomes condense, nuclear membrane dissolves, centrosomes move to opposite poles (perpendicular to before)

M-II: Spindle fibres from opposing centrosomes attach to chromosomes (at centromere) and align them along the cell equator

A-II: Spindle fibres contract and separate the sister chromatids, chromatids (now called chromosomes) move to opposite poles

T-II: Chromosomes decondense, nuclear membrane reforms, cells divide (cytokinesis) to form four haploid daughter cells

The final outcome of meiosis is the production of four haploid daughter cells

Thepotemich [5.8K]

Answer:

Last one

since Osmosis is the diffusion of water. In comparing two solutions of unequal solute concentration, the solution with the higher solute concentration is hypertonic, and the solution with the lower concentration is hypotonic. Solutions of equal solute concentration are isotonic
