Answer:
Through the photolysis of water molecules
Explanation:
<em>When the electrons in photosystem II gets excited, released and travel down to the electron transport chain, the electrons are replaced by the electron released by the cleavage/photolysis of water.</em>
<em>Water molecule is cleaved resulting in the formation of hydrogen ion, oxygen gas and electrons. The electrons then replace those lost by photosystem II.</em>
Answer:
They should think of an alternative explanation for their results.
Explanation:
The next step that the scientists should take is to interpret why their hypothesis went wrong. The researchers should look for patterns in their observations and provide an alternative explanation for the results which occurred. Based on the results and their understandings, they should further make another hypothesis and check for its authenticity.

In order to start labor, estrogen increases and progesterone decreases.
Estrogens are a class of hormones that are essential for women's healthy sexual and reproductive development. They are sex hormones as well. The majority of estrogen hormones are produced by a woman's ovaries, however minor quantities are also produced in modest amounts by the adrenal glands and fat cells.
Progesterone is a member of the progestin drug class (female hormones). By lowering the level of estrogen in the uterus, it functions as a component of hormone replacement treatment. By substituting for the natural progesterone that some women lack, it helps to initiate menstruation.
