<u> Bacterial growth curve-</u>
The phase in the bacterial growth curve which is defined by zero net growth due to a lack of nutrients and excessive waste products being present is the death phase of the growth curve.
<u>Phases of the bacterial growth curve-</u>
The bacterial growth curve is a curve that depicts the number of viable live cells in a bacterial culture over a span of time. This growth curve has four very distinct phases, which are- lag phase, log phase, stationary phase, death phase.
- Lag phase- The first phase which is the period of metabolic growth rather than division of cells.
- Log phase- The second phase where the cells are dividing and increasing in numbers.
- Stationary phase- The third phase where the bacterial cells reach a stagnant period and stop dividing due to the lack of nutrients.
- Death phase- The last phase where there is no metabolic growth or cellular division. The culture is filled with metabolic wastes from the lysis of cells.

The subunit of proteins is one protein molecule that assembles with more protein molecules to make a protein complex.
Hope this helps! ;)
Answer:
The major organs of the nervous system are the brain, spinal cord, sensory organs, and all of the nerves that connect these organs together.
The nervous system reacts to the presence of danger(instinct), stores memories, control the 5 senses, and commands the rest of the organ systems to maintain homeostasis.
The nervous system works together with the respiratory system, the circulatory system, the muscular system, and many more.
<span>If jogging you should start off with a brisk walk and transition after about 1 minute to a slow jog. Then pick up your pace as your legs become warm with increased blood flow. If biking you should do a few static calf and thigh stretches but don't extend too far as muscles are cold. Then start off your cycling at a very slow comfortable pace. After about a minute you can start to slowly increase your pace until you reach your goal.</span>
Once retinal has absorbed a photon which initiates effects that create nerve impulses, the impulses get carried to the brain, which then processes the impulses along with other signals, ultimately allowing the eyes to see.
