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

maksim [4K]

Answer:

It will take 83 days to recover the extra cost

Explanation:

To determine the length of time it will take to recover the extra cost, it will be logical that we compare the $200 extra cost to the total savings in running cost made for a year and covert this into days

The total savings in running cost is the cost savings per hour multiplied by the number of hours in a year.

The calculations are set below:

Savings in running cost per hour = $0.1

Total savings in a year = 365 days ×  $0.1 × 24 = $876

Extra cost of Energy Star refrigerator = $200

If total savings for a year is  $876 , then equivalent length of time to save $200 would be

Length of time = 200/876 × 365 days = 83 days

It will take 83 days to recover the extra cost
