There are 3 kinds of contraction in skeletal muscle:
Concentric contraction: The muscle in this contraction will gives force more than the load gives. This will make the muscle shorten as it pulling the load.
Eccentric contraction: In this contraction, the force given by muscle is not enough to pull the load. This causes the load pulling the muscle instead. So the muscle will be lengthened as the load moving away.
Isometric contraction: In this contraction, the length of the muscle will be kept same by adjusting the force given to be equal to the force needed.
Answer:
Mitosis produces 2 daughter cells which are genetically identical to the parent cell. Each daughter cell is diploid (contains the normal number of chromosomes). This is the result of DNA replication and 1 cell division. ... Meiosis is used to produce gametes (sperm and egg cells), the cells of sexual reproduction.

12. [could be both]
In order to see if something is Biotic or Abiotic, think about whether it’s alive or not.
Dissolve oxygen is just the oxygen levels in the ocean, it’s not really a living thing. While it does effect the environment, it’s abiotic because it isn’t living. Fish, however, are are biotic because they’re alive.
If you’re ever confused, just think about the basic things all living things have, which is cells, and apply it to the question. Does changing weather have cells? Nope. do trees have cells? Yep!
Also, for the Fertile soil, I said it could be both because of what’s in the soil. Fertile soil has biotic factors in it, like dead animal stuff and dead plant stuff. (Anything that was once living, even if it’s dead, is still considered a biotic by the way). I think your best bet would be to put biotic, but I might be wrong
But yeah, in summary, Biotic means living, Abiotic means non living, and in order to see which is which, ask yourself if whatever you’re questioning has cells. Good luck
