In African areas that are prone to malaria having normal blood leaves you prone to contracting malaria and death. Having sickle

cell anemia makes your blood unable to effectively transport oxygen and typically leads to early death. However, being heterozygous for normal blood and sickle cell anemia leads to the blood being able to effectively transport oxygen and resistance to malaria, allowing for a longer life expectancy.

Explain the statement “Scientific knowledge is the result of debate and conformation within the scientific community.”
spayn [35]

Answer:

What this statement means is that experimentation is not enough, but that true knowledge comes from the analysis of results in a critical and meticulous way

Explanation:

Scientific knowledge is based on the scientific method and the results of the research, however that information is useless if it is not interpreted.

When the results are analyzed by scientists who support the same theories and have the same opinions, the results are not enriched as much as when exposed to different points of view. The debate tests the hypothesis giving rise to more complete answers.

Help pleaseeeeeeeeeeeeeeeeeee
nasty-shy [4]

Answer:

Cells produce energy by breaking down sugar and other molecules in the presence of oxygen to produce ATP. So the answer is "B".

Explanation:

The process of producing ATP in animal cells occurs through cellular respiration. Various processes occur in this which involve the presence or absence of oxygen. Glycolysis in the presence of oxygen leads to the production of two molecules of ATP. Glucose is broken down into pyruvate and water.

In citric acid cycle, acetyl coA is utilized to produce <u>2ATP, 6NADH and 2FADH molecules.</u>

Finally oxidative phosphorylation occurs in mitochondria. With the help of electron transport chain, ATP is synthesized by ATP synthase enzyme.

Aerobic respiration takes place in the mitochondria and requires oxygen and glucose, and produces carbon dioxide, water, and energy.

anaerobic respiration also produces energy and uses glucose but it produces less energy and does not require oxygen.
