A. Fine Focus.
B. Nucleus, Cytoplasm, and membrane
C. 30 Micrometer.
Erythrocytes are well known to have no nucleus but in fact, they lack most organelles such as the Golgi apparatus endoplasmic reticulum and mitochondria. Hair consists of two parts the root and the hair shaft. The root is the part of the living hair located in the middle layer of the skin the dermis.
Epidermal root cells in some plants produce root hairs and tubular growths that increase the surface area of the root. Unlike other cells in the body, red blood cells do not have a nucleus. This habit dates back to when mammals began to evolve. Other vertebrates such as fish reptiles, and birds have erythrocytes that contain dormant nuclei. To allow red blood cells to carry an increased load of oxygen cells evolved to function without a nucleus and other associated organelles.

Answer:
Avirulent.
Explanation:
VIRULENCE is the ability of a pathogenic organism to infects the host, leading to damages or death of the host. The extent of these virulent effect depends on certain chemical substances ( called Virulence factors) produced during the pathogenic processes.
The virulence effects is achieved due to the ability of the virulent factor to disrupt the entire physiological mechanisms of the organisms; e,g crop plants; though suppression of the host immune response, disruptions of the immune mechanisms, colonization of the host DNA structure etc. Therefore the pathogenic effects suppressed the host resistance and spread throughout the host body system.
In this present scenario, the pathogenic effect of the likable bacteria; is not virulent, because
none of the d crop pant is completely diseased.
the nascent intenodes and leaves are growing to usual size.
Consequently, the physiological and the morphological features of the crop plants are still intact. Thus the infection is AVIRULENT.
<span>The means is unknown. Filoviruses are known for causing hemorrhagic fever in humans. However, once a human is infected, passing the virus from person-to-person is the means by which others become infected. Most especially is the transmission through infected bodily fluids or objects that have been unsterilized and come into contact with those fluids.</span>
