Some have a 30 yr life span but others have little as ten months
it all depends on the region of which it lives
Answer:
A. 1.2
Explanation:
Normally, a human body cell contains 46 chromosomes - 23 inherited from the father and the same number from the mother.
Most of the human DNA, or human genes, are located in the chromosomes.
Each metaphase chromosome consists of:
two sister chromatids containing one DNA molecule each, and since they are formed by replication, these molecules are completely identical in gene content; that is why chromatids are called sister chromatids; two centromeres, one on each chromatid.
Answer:
Fossils are important evidence for evolution because they show that life on earth was once different from life found on earth today. Paleontologists can determine the age of fossils using methods like radio metric dating and categorize them to determine the evolutionary relationships between organisms
Answer:
Genetic mutation.
Explanation:
Insects may grow used to the effects of pesticides over time (natural selection), causing their genetics to be stronger than the pesticides, while eagles (having nothing to do with pesticides, because they typically live in the air) would be affected because the presence of the chemicals are new to its genetics.
Chromosomes have lined up on the metaphase plate. During anaphase (b), the sister chromatids are pulled apart and move toward opposite poles of the cell.
