Answer:
Species 4
Explanation:
The species began to peak in population and then remained very steady
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.
Stratus is the cloud which forms near the ground.
Stratus is referred to as low-level clouds. They are being characterized by the horizontal layer which has a uniform base. Stratus is used to describing features and hazy.
Stratus clouds do produce a small amount of show or light drizzle and they are above ground. It is formed when a sheet of moist air, warm lifts off the depressurizes and ground and it follows lapse rate.
This leads to relative humidity to increase because of adiabatic cooling.
