The answer to this question is the gas carbon monoxide. Carbon monoxide is a gas that has the features of being odorless, colorless, and being tasteless. Carbon monoxide is known for the chemical formula as CO. This gas is also used as a fuel because this gas is flammable.
Answer:
Thiamine pyrophosphate (derived from vitamin B1) is a coenzyme required for the activity of pyruvate dehydrogenase enzyme complex.
Explanation:
Pyruvate is the end product of glycolysis. During aerobic cellular respiration, pyruvate is oxidatively decarboxylated into acetyl CoA which in turn enters the Kreb's cycle. Oxidative decarboxylation of pyruvate is carried out by enzyme complex pyruvate dehydrogenase (PDH). The first step is simple decarboxylation and is catalyzed by pyruvate decarboxylase of the PDH complex.
The enzyme pyruvate decarboxylase and has a tightly bound coenzyme, thiamine pyrophosphate. Thiamine pyrophosphate is derived from vitamin B1. Lack of vitamin B1 in the human diet leads to beriberi that is characterized by an increased concentration of pyruvate in blood urine since oxidative decarboxylation cannot occur due to lack of the coenzyme thiamine pyrophosphate.

Opinion on Climate Change
A poll taken in 2016 shows that 52% of Americans believe climate change to be caused by human activity, while 34% state it is caused by natural changes. Data is increasingly showing that 62% of Americans believe that the effects of global warming are happening now in 2017.
Answer: Metabolic alkalosis
Explanation: Metabolic alkalosis refers to a metabolic condition in which the tissue’s pH is increased above the normal range (7.35–7.45). This occurs as a result of decrease in the concentration of Hydrogen ion, which results to increased bicarbonate in the body system. It can also be caused by direct increase in the bicarbonate concentrations.

Whereas an onion epidermal cell has a cell wall, a human cheek cell does not. Instead, a semi-permeable membrane surrounds the cytoplasm of the cheek cell. While there are chloroplasts present in onion cells, they are absent in cheek cells. </span>
