The correct answer is estrogen.
<span>Endometrial glands are uterine glands located inside the endometrium. Their appearance varies during the menstrual cycle and it is under the influence of hormones. For example, during the proliferative phase, uterine glands appear due to estrogen secretion by the ovaries while during the secretory phase, due to increase in progesterone secretion, the uterine glands become very coiled with wide lumens and produce a secretion. </span>
Answer:
D All of the above
Explanation:
Like our bones, bones in fish can provide general protection and support to their body.
(Fun fact, jellyfish do not have bones, so when they are out of the water, they loses their bell shape structure and looks more like a flat piece of jelly. But fish tends to look the same when it is in water and out of water.)
The bone is also where the muscles will attach to, which allows for movement.
(Imagine our fingers, the muscles in our fingers are attached to our bones, which allows us to do things like typing.)
Bones can also protect the fish's brain.
(Brain can be very fragile and soft, so having a hard structure around it can protect the brain. It's kind of similar to protecting the liquid egg in an egg shell.)
