Answer:
progesterone
Explanation:
Progesterone, unlike estrogen, has no activity on determining female sexual characteristics. Progesterone activity is to prepare the uterus for possible pregnancy by growing the endometrial lining of the uterus and receiving the fertilized egg and stimulating milk production.
Progesterone is directly responsible for maintaining and sustaining the fetus in the womb, stimulating, during the first two weeks of pregnancy, the fallopian tube and endometrial glands to secrete nutrients essential for the zygote. Uterine contractions are inhibited to prevent the fetus being expelled as it blocks prostaglandin production and decreases oxytocin sensitivity.
Answer:
Option C
Explanation:
Energy conservation is a set of practices followed to save energy. This can be done in two ways
a) Using energy efficiently so that even a small amount of energy with much higher efficiency is sufficient to cater the demand of people
b) Reduce the dependency on non-renewable energy resources and promote use of greener energy
c) Reducing the usage
Hence option C is correct
<span>ileocecal valve or sphincter</span>
It is called <span>hemoglobin</span>
I believe that sliding filament model of contraction states that; during contraction, the thin filaments slide past the thick filaments so that actin and myosin filaments overlap. According to this model the myosin or thick filaments of muscle fibers slide past the actin or thin filaments during muscle contraction, while the two groups of filaments remain at relatively constant length.
