Which situation would result in a theory being replaced rather than revised

Biology
1 answer:
Slav-nsk [51]3 years ago
5 0

<u>Answer:</u>

A theory would be entirely replaced if a new information is discovered that contradicts with the previous theory.

Explanation:

Theories are made after being properly investigated and by having a large amount of supporting data.

But theories can be subjected to entirely change and be replaced if a new theory comes up that contradicts with the previous theory. As science is an emerging field and new researches are conducted day by day so previous theories can be wrong. However, the new theory should have enough evidence and reasoning to prove that the previous theory was wrong.

Why are there different normal values for hemoglobin levels and rbc count in males and females?
alina1380 [7]
<span>Women's mean hemoglobin levels are about 12% less than the mean hemoglobin levels of men. This sex-related difference is observed in many species of animals, such as birds and reptiles. It's believed this difference exists in humans between males and females because men have larger bones, which means they would have more blood cells producing bone marrow. Additionally, men's kidneys have a larger diameter than women's kidneys, which would lead to increased red blood cell production.</span>

Cellular respiration requires oxygen which is also called aerobic respiration. There are stages of cellular respiration and they include; glycolysis, pyruvate oxidation, Krebs cycle or citric acid and oxidative phosphorylation.

What facts can you compile that would support a theory that multicellular eukaryotes developed from unicellular prokaryotes?
Delicious77 [7]

Answer:

Multicellular eukaryotes evolved from unicellular prokaryotes by the process of endosymbiosis

Explanation:

All living beings have evolved from three groups of animals closely related with each other.Domains: Archaea,bacteria and eukarya.the archaea and bacteria are unicellular organism surrounded by single cell water and  and coiled stand of DNA. Eukaryotic cells are more complex and with a linear  strand of DNA which is in the nucleus. Actually mitochondria which had evolved from a free living bacterium which was swallowed by another cell. The host cell benefited from the chemical energy that mitochondria produced and mitochondria in turn is benefited to be inside the protected environment. Mitochondria is the main organelle which the multicellular eukaryotes with unicellular prokaryotes.
