The approach assumes that events are governed by some lawful order.
DerKrebs [107]

Answer:

scientific

Explanation:

A scientific method can be defined as a research method that typically involves the use of experimental and mathematical techniques which comprises of a series of steps such as systematic observation, measurement, and analysis to formulate, test and modify a hypothesis.

A hypothesis is considered to be tentative or an educated guess and can be defined as a testable explanation for an observation or a scientific problem. An example of a hypothesis is saying, Corona virus is caused by the introduction of the "5G" technology.

Thus, for any hypothesis to be true and acceptable in science, it must be supported by observations and the results of control experiments; this give rise to factual informations, theories and by extension solutions to problems. Consequently, we can deduce from the aforementioned paragraphs that a scientific method is simply an organized way to test scientific ideas and hypothesis.

Basically, the goals of science include the following;

I. Measurement and description of events or subjects that are being studied through research and experimentation.

II. Understanding and prediction of the natural and physical world by understanding the reason for each occurrence.

III. Application of scientific laws and control of mechanisms to proffer solutions to practical or real-life problems.

<em>In conclusion, the scientific approach assumes that events are governed by some lawful order by uncovering all of the laws or consistencies associated with them.</em>

In a situation where you want to perform one action when a Boolean expression evaluates as true and an alternate action when it
Ghella [55]

Answer:

if-else

Explanation:

Based on the information provided within the question it can be said that the best statement to use in this situation is an if-else statement. Like mentioned, this is a statement that outputs two different results depending on whether or not the input meets a predefined set of rules.

For Example: Input is 17

if (hour < 18) {

 greeting = "Good day";

} else {

 greeting = "Good evening";

}

Output would be "Good evening" in this situation

How does water's role in photosynthesis explain
Vera_Pavlovna [14]

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.
