Prokaryotic cells are simple, ancient cells without a nucleus. Eukaryotic cells are more complex and have a nucleus.
Answer:
Hypoxia is believed to be caused primarily by excess nutrients delivered from the Mississippi River in combination with seasonal stratification of Gulf waters. ... Stratification of fresh and saline waters prevents oxygen replenishment by mixing of oxygen-rich surface water with oxygen-depleted bottom water.
Answer:
can adapt to environment, access to food, ability to mate and reproduce
Explanation:
yea this should be right
If you were able to look very closely at a portion of dna and find methylated histones, you would be looking at a region of inactive chromatin.
- Histone methylation is the process by which methyl groups are added to the histone protein amino acids, which create the nucleosomes around which the DNA double helix coils to form chromosomes.
- Histone methylation is the addition of one, two, or three methyl groups to certain amino acids within a histone protein. Histones are coiled around DNA in the cell nucleus.
- These findings collectively imply that DNA methylation can be either active—as a probable contributor to levels of gene expression variation—or passive—as a result of or a separate indicator of gene expression levels.

Mitosis is important because this is the stages (cell cycle) in a cell where the chromosomes are split into two and have their own nucleus. There are seven stages to this process
1. Interphase
2. Prophase
3.Prometaphase
4.metaphase
5. Anaphase
6. Telophase
7. Cytokinesis
