The scientist can tell that punctured equilibrium has occurred if they have examined the fossil fuels and can see that one organism rapidly evolved different characteristics.
Answer: Option D
<u>Explanation:</u>
Punctured Equilibrium is an evolutionary theory which proposes that the species appearing in the fossil's record will show little evolutionary changes. In punctuated equilibrium, change occurs gradually, First very little change can be seen which later results in the occurrence of huge changes.
Such huge changes can be clearly seen by examining the fossil records. Thus if there is any evolutionary changes seen in the fossil's record, the scientist can conclude the occurrence of punctuated equilibrium.
B. the addition of one phosphate group
The reason of the protein digestion process is that the dietary protein is reduced into a group of amino acids in the gastrointestinal tract. Proteins are globular molecules that are comprised of smaller molecules called amino acids.
Cells divide for growth, to repair tissue damage, and because the nucleus can only control a certain size of cell.
Answer:
Plague is caused by Yersinia pestis. It is unicellular and placed in the bacteria domain.
Explanation:
Plague is caused by bacteria Yersinia pestis , a zoonotic bacteria usually found in the small mammals and their fleas. It is a gram-negative, nonmotile, rod-shaped, coccobacillus bacteria, with no spores. It is a facultative anaerobic organism that can infect humans via the Oriental rat flea.Y. pestis was discovered in 1894 by Alexandre Yersin, a Swiss/French physician and bacteriologist from the Pasteur Institute, during an epidemic of the plague in Hong Kong. Yersin was a member of the Pasteur school of thought. Kitasato Shibasaburō, a German-trained Japanese bacteriologist who practised Koch's methodology, was also engaged at the time in finding the causative agent of the plague. However, Yersin actually linked plague with Y. pestis. named Pasteurella pestis in the past, the organism was renamed Yersinia pestis in 1944.
