Answer:
phages are non-living biological entities that can produce numerous copies of themselves, forming ordered three-dimensional structures on a nanometre scale
Explanation:
A phage (i.e., a bacteriophage), is a virus capable of infecting and replicating within bacteria. Bacteriophages are composed of proteins forming a capsid that encapsulates the genetic material (either DNA or RNA genome), which may contain a variable number of genes. Bacteriophages, and viruses in general, can be considered nanomachines capable of producing numerous copies of themselves with high fidelity by utilizing the molecular machinery of the host bacterial cell. In biotechnology, it has been proposed to exploit the knowledge about bacteriophage reproduction to design diverse nanostructures.
Specialized epidermal cells aim to increase the absorption surface in the root system of a grass plant.
<h3>What are specialized cells?</h3>
They are those committed to the fulfillment of a specific function within a cellular system or tissue.
These help to absorb nutrients and are found, fundamentally, in the piliferous zone of the root.
Therefore, we can conclude that specialized epidermal cells aim to increase the absorption surface.

Answer:
conditioned response
Explanation:
The conditioned response, in classical conditioning, is the learned reaction that is elicited by an organism to a previously neutral stimulus, which is now a conditioned stimulus.
In the experiment of Pavlov, where the dog was taught to salivate by presenting food and the sound of the bell at the same time, the dog learns to salivate at the sound of bell alone even without food. This response of the dog is termed a conditioned response to a conditioned stimulus (sound of bell).
1. Organelles-. e.g. mitochondria, nucleus.
2. Cells- e.g. epithelial cells, palisade cells.
3. Tissues- e.g. muscles, connective tissue.
4. Organs- e.g. heart, liver.
5. Organ systems- e.g. digestive system, circulatory system
This is because there are many organelles inside a cell and a collection of same cells that creates tissues, a collection of tissues form organs, to carry out a particular function, and a collection of organs working together is an organ system. I think this is what they're after as I had a similar question a little while ago.
