Answer:
The answer to your question is: after two hours there will be 6400 cell/ ml
Explanation:
Data
Bacteria t = 0; 400 cells/ml
generation time = 30 minutes
# cells after two hours = ?
# of bacteria time
400 0
800 30 min
1600 60 min
3200 90 min
6400 120 min
D. Lysogenic cycle. In this cycle, viral DNA is inserted into the host cell's DNA. It divides with mitosis, soon creating many infected host cells. Once the lytic cycle is triggered (usually from external factors), the viral DNA is transcribed/translated into viruses.
Answer:
Immune
Explanation:
The immune system helps to protect our body from all sort of organisms ranging from invading toxins and micro-organisms which negatively affects an individual’s health and well being.
Stress has an adverse effect on the immune system such that it weakens and suppresses the functions of the required antibodies in the body system. This is the reason why many aged people fall sick because they have gone through more stress when compared to younger people.

Answer:
It is important that cell growth in a multi-cellular organism be regulated carefully so as to maintain the integrity of the cell cycle
Explanation: Each cell in a multi-cellular organism has it cycle which consist of the inter-phase and the m-phase (active division). Cell growth takes place in the G1 phase of the inter-phase and this ensures that deoxy ribonucleic acid is synthesized in the S-phase in preparation for division.
Hence, adequate cell volume is a key event in order for division to take place. If cell growth is not regulated, it might result in a cell exiting the cell cycle into the resting phase in case of slow growth or result in over-division of a cell in case of over-stimulated growth. The latter is often the case in the development of cancerous cells.
