Answer:
The simplest virions consist of two basic components: nucleic acid (single- or double-stranded RNA or DNA) and a protein coat, the capsid, which functions as a shell to protect the viral genome from nucleases and which during infection attaches the virion to specific receptors exposed on the prospective host cell.
Since this is movement that is occurring against the natural movement from high to low concentration, this is Active transport.
The option C.
Answer:
Autotrophs. An organism like a green plant that can make its own food are called an autotrophs. Autotrophs can make their own food through the process of photosynthesis. Photosynthesis is present in these organisms, a mechanism where they gather, water from the soil, heat from the sunlight though the pigment called chlorophyll and carbon dioxide in the air to manufacture and generate its own food. Autotrophs are also the primary sources of food in the food chain which contains immense amount of calories.
