Zepler [3.9K]

Answer:

Little increase in cell number

Explanation:

There are four distinct phases in the bacterial growth curves that is lag, log, stationary and death phase. The lag phase of the bacterial growth curve is characterized by very little increase in the cell number.

The growth rate of bacteria in the lag phase is slow because the medium is new to the bacterial culture and it requires time for bacteria have to adapt to the new cultural environment and to synthesize enzymes required for substrate utilization.  

After getting adapt in their new environment bacteria starts to grow at an exponential rate. So little increase in cell number characterizes the lag phase.

omeli [17]

Answer:

B) hypertension and bradycardia.

Explanation:

Autonomic dysreflexia is a syndrome which is characterised by the sudden rise in the blood pressure of the human. The disease is common in the people with a higher level of spinal cord injuries above the T6 level.

The condition occurs when some external stimuli like pain or irritant activate the involuntary response in the body which cause the blood pressure to rise (hypertension). This leads to the slowdown of the heartbeat (bradycardia) to restore the blood pressure but the body cannot restore the blood pressure due to the damage in the spinal cord.

Thus, Option-B is the correct answer.
