Answer:
Scientific method
Explanation:
The scientific method is a systematic process used by scientists to explore observations, formulate hypotheses, and conduct experiments to investigate questions about the natural world. This method includes steps such as observation, hypothesis formation, experimentation, and analysis of results. It is adaptable and applicable to many fields of study.
A series of steps that guide scientists to investigate questions about the natural world is known as the scientific method. This process is integral to the way scientists explore observations, develop hypotheses, and conduct experiments. It typically begins with an observation that leads to a question. Following this, scientists engage in background research to frame a hypothesis, which is then rigorously tested through experimentation. After data collection, the results are analyzed, leading to conclusions that can either support or refute the hypothesis. Importantly, the scientific method is adaptable and can be applied beyond traditional scientific disciplines, embodying a standardized approach to problem-solving and inquiry.

What's the waste product of electrons and pyruvate combining in fermentation?
Answer:
Lactate
Explanation:
Under the conditions of oxygen scarcity, pyruvate does not enter the Kreb's cycle in the form of acetyl CoA. Rather pyruvate is reduced into lactate by accepting the electrons from NADH. Reduction of pyruvate and oxidation of NADH form lactate and NAD+. The process is called lactic acid fermentation.
Here, the NAD+ enter the glycolysis to continue the energy production while lactate is a waste product.

Alcohol builds up in the bloodstream after a person consumes more than how many drinks per hour? 1 2 3 4
Answer:
Option B, 2
Explanation:
As per the standard rule if a person taken one drink per hour then he/she gets enough time to burn off the alcohol consumed irrespective of number of drinks taken at the same rate. Hence, there is no accumulation of alcohol in the body.
However, if a person intakes more than one drink per hour then alcohol starts building/accumulating with in the blood stream. After consuming 2 drinks per hour , one is dissolved but the other one accumulates.
Hence, option B is correct.
The human body can metabolize approximately one standard drink per hour. Consuming more than this causes alcohol to build up in the bloodstream, with potential negative effects such as reduced reaction times and lowered alertness. Factors such as body weight, genetics, and consumption rate can affect how quickly alcohol is metabolized.
Explanation:Alcohol is metabolized and removed from the body at a certain rate; this rate slightly varies between individuals, typically being slower in women compared to men. On average, the human body can metabolize approximately one standard drink per hour. Drinking more than this will cause alcohol to build up in the bloodstream, resulting in higher blood alcohol concentrations. Consider that factors such as body weight, genetics, and consumption rate may also affect how quickly one can metabolize alcohol.
Drinking more than the body can metabolize can lead to riskier effects. Some effects of consuming a large quantity of alcohol include decrease in visual acuity, slow reaction times, lowered alertness, and loss of behavioural control. Excessive consumption can result in complete loss of consciousness and in some cases, can lead to health problems such as Fetal Alcohol Spectrum Disorder (FASD) in infants if consumed by a pregnant woman.
It's important to be aware of one's own drinking habits and the potential effects. Practicing moderation and understanding the body's limits when it comes to alcohol can help promote healthier and safer behaviour.
