Answer:
B. It's much harder to provide the right atmospheric environment to cultivate obligate anaerobes, so it's been harder to study them.
Explanation:
Obligate anaerobic bacteria are the ones that can grow only in the absence of oxygen. These bacteria do not derive the energy from aerobic cellular respiration and die when exposed to the presence of oxygen.
Owing to their oxygen sensitivity, the culturing of obligate anaerobic bacteria requires special equipment to ensure the absence of oxygen.
The presence of aerobic conditions in laboratories makes their culture and study harder than that of the aerobic or facultative anaerobic bacteria.
Answer:
The answer is the Algonquin, Abenaki and the Shawnee
If this is a true/false question, the answer is true. oxygen and co2 exchange happens at the capillaries.
Answer:
Option-C
Explanation:
A pulse-chase experiment which is used to study the cellular process taking place in the cells. This uses the labelled molecule which is incorporated into the cellular pathway and then the unlabeled molecules are used over time to determine how much time is required by the unlabeled molecule to replace the labelled molecule.
In the given question, the pancreatic cell which secretes the digestive enzyme known as the acinar cell is labelled with the leucine and then used unlabeled leucine.
When observed after three hours, the black spots will appear on the exterior of the cell as the protein has been synthesised by the ER and now has been secreted from the cell.
Thus, Option-C is the correct answer.
