The claims are based on empirical evidence and are likely to be pseudoscientific. They are not particularly useful. Therefore, option A is correct.
What is pseudoscience?A statement, discovery or explanatory system that is presented as pseudoscience lacks the objectivity required by the scientific process. Research that is based on dubious ideas, a defective experimental design, or unreliable data can also lead to pseudoscience.
Pseudoscience may be presented in good faith due to incomplete or inaccurate data analysis. However, it is also possible to deliberately apply scientific methods incorrectly in order to instill unjustified confidence in conclusions that would not be supported by a more rigorous approach.
These claims are pseudoscientific. Hence, option A is correct.

Hydrofluorocarbons (HFCs) were used to phase out chlorofluorocarbons (CFCs), which were used as aerosol propellants, refrigerants, and coolants. Members from 197 nations meeting at the summit of the United Nations Environment Programme in Kigali, Rwanda reached a legally-binding accord to phase out HFCs in an amendment to the Montreal Protocol due to HFCs potential for A) global warming. B) increased cancer incidence. C) toxicity and biomagnification in aquatic ecosystems. D) contributing to habitat destruction of endangered animals.
Answer:
Members from 197 nations meeting at the summit of the United Nations Environment Programme in Kigali, Rwanda reached a legally-binding accord to phase out HFCs in an amendment to the Montreal Protocol due to HFCs potential for global warming.
Explanation:
The Phase-out Management Plan (HPMP) for Hydrochlorofluorocarbons (HCFCs)
Under the Montreal Protocol on Substances Depleting the Ozone Layer, in particular the Executive Committee (ExCom) 53/37 and ExCom 54/39, the Parties to this Protocol agreed to set 2013 as the time for developing countries to freeze consumption and development of HCFCs. For developing countries, the decline in consumption and production of HCFCs started in 2004 and 2010, respectively, with a decline of 100% set for 2020. Developing countries have agreed to start reducing their HCFC consumption and output by 2015, with a reduction of 100% set for 2030.
Hydrochlorofluorocarbons are a category of man-made compounds containing hydrogen, chlorine , fluorine and carbon, generally referred to as HCFCs. In nature, they are not found anywhere. After countries decided to phase out the use of CFCs in the 1980s, which were found to be damaging the ozone layer, HCFC production began to take off. HCFCs are used for refrigeration, aerosol propellants, foam processing and air conditioning, much like CFCs. However, unlike CFCs, most HCFCs in the lowest part of the atmosphere are broken down and pose a much smaller danger to the ozone layer. Nonetheless, considering their very low atmospheric concentrations, HCFCs are very potent greenhouse gases, measured in parts per trillion. Compared to CFCs with ODP 0.6-1.0, these HCFCs have lower ODPs (0.01-0.5) in terms of ozone depletion potential (ODP). Compared to CFCs with a GWP of 4,680-10,720, HCFCs have lower GWPs (76-2,270) in terms of global warming potential ( GWP).
Hydrofluorocarbons (HFCs), manufactured mostly in developing countries, have replaced CFCs and HCFCs. HFCs do not cause damage to the ozone layer because they do not contain chlorine, unlike CFCs and HCFCs. However, they are greenhouse gases, similar to that of CFCs and HCFCs, with a strong global warming potential ( GWP).
In the other three options ,there is no role of the members from 197 nations meeting at the summit of the United Nations Environment Programme in Kigali.
Hence, the correct option is A.
Gene investigated the effect of moisture on the rate of growth of mold on bread. He put two identical slices of bread on separate plates. He made one slice moist and kept the other slice dry. He left the uncovered plates on a table for 2 hours. Then, he sealed them in plastic bags and put them in a dark, warm place. He looked at them each day for five days. After five days, he observed that 50 percent of the moist slice was moldy, and none of the dry slice was moldy. If Gene observed the slices for three more days, what would he most likely observe?
There would be less mold on the moist slice. There would be more mold on the moist slice. There would be the same amount of mold on each slice. There would be no change in the amount of mold on either slice
Answer:
More mold on the moist slice
Explanation:
Assuming that the trend continues, then after another 3 days, a higher percentage (more than the original 50%) of mold will be found on the moist slice, while the dry slice may either be unaffected or may develop very little mold.

Accidents can occur in meiosis wherein members of a chromosome pair fail to separate at anaphase. This is called _____.
Answer:
Accidents can occur in meiosis wherein members of a chromosome pair fail to separate at anaphase. This is called nondisjunction.
Explanation:
Answer:
Nondisjunction
Explanation:
Nondisjunction occurs when homologous chromosomes or sister chromatids fail to separate during mitosis or meiosis. This leads to daughter cells with unequal amounts of DNA. In fetuses in particular, this type of accident can have extreme consequences, such as the birth of a child with Down's Syndrome or a premature death.

why is the composition of oxygen in the alveoli lower than the composition of oxygen in the atmosphere?
Answer/ Explanation:
The respiratory system works to humidify incoming air, thereby causing the air present in the alveoli to have a greater amount of water vapor than atmospheric air. Alveolar air contains a greater amount of carbon dioxide and less oxygen than atmospheric air.
A few other reasons are....Alveolar air is partially replaced by atmospheric air during each breath
Oxygen is constantly absorbed into the blood from alveoli
Carbon dioxide is diffused into alveoli from blood
As air enters respiratory passages it becomes humidified diluting the inspired gases' partial pressures
