A because radiometric dating is done by determining the relative proportions of particular radioactive isotopes present in a sample.
Hope this helps

Germ cells have only half the number of chromosomes as a diploid cell one of each pair - and are termed haploid (n). In a human egg or sperm, there are 23 chromosomes, one of which is an X or Y.Feb 16, 2000
Answer:
Equatorial plate/ metaphase plate
Explanation:
The cell cycle consists of 4 phases:
- G1 phase
- S phase
- G2 phase
- M phase
M phase is further divided into mitosis and cytokineses.
In <u>mitosis</u>, the <u>cell divides its chromosomes</u> whereas in<u> cytokinesis the division of cell contents takes place resulting in two daughter cells</u>.
Mitosis is further composed of:
- <u>Prophase</u> (chromosomes condense and mitotic spindles are formed)
- <u>Metaphase</u> (<u>chromosomes align along the equatorial plate or metahase plate</u>)
- <u>Anaphase</u> (chromosomes are separated and move towards their respective poles)
- <u>Telophase</u> (chromosomes have reached their respective poles and nuclear membranes starts forming around the newly separated chromosomes)
<u>QUESTION:</u>
<u>During metaphase the chromosomes line up along the middle of the cell called the metaphase plate or equatorial plate.</u>
