The best answer is B.
An animal like the Llama lives in high altitudes from 7,400 to 12,800 meters above sea level.
When compared to other animals, Llamas have a lot more red blood cells per unit than other animals. More red blood cells mean more hemoglobin.
When hemoglobin combines with oxygen, oxyhemoglobin is formed. Thus oxyhemoglobin in Llamas is greatly increased than in most other animals and the Llamas are able to thrive in high altitude areas where oxygen is thinner.

Answer:
Population of lions are more than cheetahs and zebras.
Explanation:
The chart provides information about the population sizes of Lions, Cheetah and Zebras. According to this information, population of lions is the greatest as compared to Cheetah and Zebras. This is due to suitable conditions for the lions such as food and shelter etc in that jungle of Africa as well as strong competitor and its aggressive behaviour make them successfully survive and increase its population in the jungle.
Answer:
Explanation:
The O-F glucose test (oxidative-fermentation) is used to determine whether an organism is performs oxidative or fermentative metabolism.
Oxidative metabolism (i.e respiration) takes place in the presence of oxygen while fermentative takes place in the absence of oxygen.
Facultative anaerobes can carry out both fermentation and respiration.
The O-F medium has glucose, peptones and a pH indicator. When the pH of the medium is acidic, that is glucose has been broken down, the medium turns yellow. When it is basic, it turns blue implying that peptone and not glucose had been broken down.
The sealed tube is overlaid with oil so as to prevent oxygen from getting in, making it anaerobic.
The unsealed tube allows oxygen.
Enterics would be yellow is both tubes because they are facultative anaerobes and can grow in the presence or absence of oxygen, hence they carry out both respiration and fermentation.
