Plate boundary volcanism. Volcanic activity occurs at two types of plate boundaries: mid-ocean ridges and subduction zones. At mid-ocean ridges, basaltic eruptions produce new sea-floor crust.
Environmental conditions in enzyme functions both regulate to stay the same
Epithelial tissue covers the body surface and forms the lining for most internal cavities. The major function of epithelial tissue includes protection, secretion, absorption, and filtration.
<u>Explanation:</u>
- Epithelial tissue spreads throughout the body surface covering line body cavities and hollow organs which form the major tissue in the glands. Epithelial tissue covers the outside of the body and lines organs, vessels, and cavities.
- Endothelium joins with the inner tissue lining which covers the brain, lungs, skin, and the heart. It acts as a barrier protecting the body and the environment and maintains the process of protection, filtration, absorption, excretion, and sensation.
- Covering and lining epithelium and the Glandular epithelium which helps in surrounding the glands within the body surface are the characteristics feature in the human body.

I snatched this from someone else, so it isn't mine, but I hope it helps. They don't have a username so I cannot credit them.
Explanation:
DNA content is halved in both meiosis I and meiosis II. Ploidy level changes from diploid to haploid in meiosis I, and remains haploid in meiosis II.
During anaphase of both meiosis I and meiosis II, the DNA content (number of copies of chromosomes) in a cell is halved. However, the ploidy level changes only when the number of unique chromosome sets in the cell changes. This occurs only in meiosis I (where separation of homologous chromosomes decreases the ploidy level from 2n to n and produces daughter cells with a single chromosome set).
