Gastro-esophageal reflux disease is a disease in which the upset stomach causes re-flux of acid back to esophagus. This may produce highly uncomfortable feeling of chest burn that may last even for two hours. GERD can get worse after eating because more volume of acids are released by stomach on detection of food like fast food and food that have high protein content. Patients are recommended to lose weight because that loses the pressure on abdomen a decreases the chance of GERD. Head elevation is also recommended to keep the acid within the stomach.

GERD symptoms may have some respiratory complications like lung inflammation and chest congestion due to the action of stomach acid. This may lead to asthama.
A challenge to traditional (pre-1860) ideas about species came from embryology, when it was discovered that embryos of dissimilar organisms, such as sharks and humans, resemble each other. Embryology involves the study of the formation and the development of an embryo and the fetus. It is one type of evidence of evolution such that the embryos of many different kinds of animals, mammals, reptiles, birds, fish among others, are similar showing a common ancestry.
Answer:
Enzymes speed up a chemical reaction making the reaction easier to occur.
- The question can be solved by using the difference between eukaryotic and prokaryotic cell.
- Prokaryotic cell does not have a well defined nucleus. The nuclear material lies naked in the cytoplasm. It is known as nucleoid. While, eukaryotic cell has a well defined nucleus with a nuclear membrane.
- Prokaryotic cell has a single chromosome while eukaryotic cell has more than one chromosome.
- Finally, prokaryotic cell do not have membrane-bound cell organelles while eukaryotic cell have membrane-bound cell organelles.
Hope you could get an idea from here.
