Answer:
- All of the above<u>(experience a negative physiological response to negative infant emotion; evaluate an infant s negative emotional expressions as aversive and threatening; experience a fear of being rejected by the infant, a negative emotion stemming from their own attachment history</u>.)
Explanation:
Dismissive or uninvolved parents are described as the ones who are completely neglectful or irresponsible to the needs of their child and fail to provide them even the basic necessities like food, affection, and care. These parents tend to reflect a kind of bias when they witness infants expressing negative emotions as they were quite dismissive to realize that a child requires positive and healthy environment to have a positive social-learning.
These parents would evaluate their negative emotions as threats or aversion due to their own inability to realize the actual reason(which is their dismissive behavior from which the infant learns) for such a negative response. The uninvolved parents may even feel that they could be rejected by the baby as they associate it to their own personal(attachment) history rather than attempting to know the cause of infant's negative behavior. Thus, <u>all of the above</u> are correct in case of a 'dismissive or univolved parents'.

um please give more details about what we have to do in the question that's would be helpful.
At a fundamental level, water provides electrons to replace those removed from chlorophyll in photosystem II. Also, water produces oxygen as well as reduces NADP to NADPH (required in the Calvin cycle) by liberating H+ ions
During the process of photosynthesis, six molecules of carbon dioxide and six molecules of water react in the presence of sunlight to form one glucose molecule and six molecules of oxygen. The role of water is to release oxygen (O) from the water molecule into the atmosphere in the form of oxygen gas (O2).
Water also has another important role of being an electron feeder. In the process of photosynthesis, water provides the electron that binds the hydrogen atom (of a water molecule) to the carbon (of carbon dioxide) to give sugar (glucose).
Water acts as a reducing agent by providing H+ ions that convert NADP to NADPH. Since NADPH is an important reducing agent present in chloroplasts, its production results in a deficit of electrons, resulting from oxidation of chlorophyll. This loss of electron must be fulfilled by electrons from some other reducing agent. Photosystem II involves the first few steps of the Z-scheme (the diagram of the electron transport chain in photosynthesis) and therefore a reducing agent that can donate electrons is required to oxidize chlorophyll, which is provided by water (acting as a source of electrons in green plants and cynobacteria). Hydrogen ions thus released create a chemical potential (chemiosmotic) across the membrane that finally results in synthesis of ATP. Photosystem II is the primary known enzyme that acts as catalyst in this oxidation of water.
