lbvjy [14]3 years ago
5 0

Answer:

PCBs and DDT are chemicals that were banned more than 30 years ago, but our air, water, land, and bodies are so contaminated that decades of cleanup efforts have yet to eliminate their threats to our health. Today, food is one of the most likely exposure routes to PCBs.

During which stage of mitosis do the centromeres split
larisa86 [58]
Mitosis is split into 4 phases.
P - prophase
M - metaphase
A - anaphase
T - telophase

During Metaphase, Chromosomes align singly along the metaphase plate.

During Anaphase, kinetochore microtubules shortens and non-kinetochore microtubules lengthens, allowing the chromosomes' centromeres to separate.

Therefore, the answer is anaphase.

P. S. centromeres separates, not split.

g100num [7]

Answer:

True

Explanation:

Unlike eukaryotic cells, which have a nucleus that contains the genome and is separated from the cytoplasm by a membrane, the prokaryotic nucleoid is not membrane-bound and is not considered an organelle. The nucleoid is simply the area within a prokaryiotic cell where its DNA is located.
