<span>Because an increase in oxytocin level increases the contractions </span>

Oxytocin can be defined as a hormone that usually acts on organs of the body which includes the uterus and breast. They can also act as a chemical messenger in the brain by controlling some important aspect of reproductive system such as lactation and childbirth. However, the positive feedback mechanism of oxytocin is that an increase in release of oxytocin will stimulate more contractions.

The cell you are examining under the microscope appears to contain a nucleus. This organism belongs to the domain:________
igor_vitrenko [27]

The cell you are examining under the microscope appears to contain a nucleus. This organism belongs to the domain <u>Eukarya</u>.

  • The only domain that includes multicellular, visible organisms including humans, animals, plants, and trees is eukaryote.
  • Numerous microorganisms, including fungi, algae, and micro-animals, also call it home. Since fungi are so diverse, two distinct fungi may have genetic differences comparable to those between a person and a fish.
  • Eukarya are eukaryotes, which have organelles and nuclei that are bound to membranes. Prokaryotes are older, less numerous, and simpler than eukaryotes.
  • Eukarya refers to creatures with nuclei in their cells. Additionally, it is the only realm in which multicellular observable organisms, such as people, animals, plants, and trees, exist. Achaea and bacteria are unicellular organisms without nuclei.

The change of cell volume is principally due to the loss or gain of
Anna11 [10]

Answer:

Water

Explanation:

In simple words, the volume of a cell refers to <u>the amount of water it contains</u>.

In eukaryotic cells may change their volume according to the effects of either the loss or gain of water. Furthermore, these changes in cell volume are extremely important as they work as a signal for different cell processes such as migration, proliferation, or death.

Therefore, the change of cell volume is principally due to the loss or gain of <u>water</u>.
