Answer:
447 calories
Explanation:
1 gram of fat is 9 calories
1 gram of carbohydrate is 4 calories
1 gram of protein is 4 calories
In one granola bar:
5 grams of fat = 5 x 9 = 45 calories
19 gram of carbohydrates = 19 x 4 = 76 calories
7 grams of protein = 7 x 4 = 28 calories
for a total of 45 + 76 + 28 = 149 calories
If Carter ate 3 granola bars then 149 x 3 = 447 calories
<u>Answer:</u>
<em>Colchicine is also known as mitotic poison. When it is added the separation of chromosomes of daughter cells are stopped. </em>
<u>Explanation:</u>
This is because the formation of spindle fiber is not allowed in the mitosis phase. Basically it is the process of arresting the mitosis at metaphase to study the chromosomes properly.
The addition of colchicine prevents the chromosomes to move to opposite poles. It makes the cell polyploidy. Hence the of addition of colchicine is the polyploidy of the cell.
Answer:
4. The suspected causative agent must be isolated from the diseased host and grown in pure culture
Explanation:
Robert Koch (1843-1910) was one of the most important bacteriologists of all time. Famous for discovering the tuberculosis bacillus (precisely on March 24, such as today, in 1882), he also discovered the cholera bacillus and is considered the founder of bacteriology. He worked on the isolation of infectious agents and reinfections from pure cultures, experiences from which he established the "Koch Postulates".
These postulates have been taken as a reference that describes the etiology of all the causative agents of an infectious disease, although they were originally used to describe only the tuberculosis bacillus. They are the following:
1- The agent must be present in each case of the disease and absent in the healthy.
2- The agent should not appear in other diseases.
3- The agent must be isolated in a pure culture from the lesions of the disease.
4- The agent has to cause the disease in an animal that can be inoculated
