A tissue.
Then a group of tissues that work together is an organ.
The a group of organs is an organ system.
A group of organ systems is and organism.
Answer:
The correct answer is D viruses that enter a lysogenic cycle do not immediately kill a host cell.
Explanation:
Lysogenic cycle is carried out by lambda phage which integrate its DNA with the genome of bacteria resulting in the formation of prophage.
The phage DNA replicate along with bacterial DNA and exist in this form for a period of time until the phage DNA recognizes any type of mutation such as exposure to ultraviolet ray which helps the lambda phage to enter the lytic cycle.
With a light microscope one can view the nucleus and endoplasmic reticulum, large vacuoles etc
The resolution of a light microscope is dependent on the wavelength of light that is the main beam of illumination. Light has approximately 0.4 um (UV)- 0.7um (Infrared) wavelength. Organelles smaller than about 0.5 um will be difficult to discern with a light microscope.
With an electron microscope one can view, in addition, even the ribosomes and mitochondria, chromosomes, tubules etc.
An electron microscope can discern very minute details of a cell. This is because its resolution is dependent on the very small wavelength of a beam of electrons which is approximately 0.002 um (about 10,000 times powerful than a light microscope)
